American documentarian "Blackfish" was released in 2013 and was directed by Gabriela Cowperthwaite. Tilikum, an orca kept by SeaWorld, and the debate concerning orcas in captivity are discussed. Four details from the movie that I found impressive are listed below, along with how each detail pertains to the movie's stance on whether or not orcas should be kept in captivity:

1. Orcas are very clever creatures. They have a sophisticated social structure and use a range of noises to communicate with one another.². The argument made in the movie is that keeping them in captivity is cruel since it robs them of their social structure and natural habitat.

2. Captive orcas live shorter lives than their wild counterparts. The movie claims that the average lifetime of caged orcas is about 25 years, as opposed to 50–60 years for those living in the wild3. This is a result of their abnormal surroundings and the stress of confinement.

3. Captive orcas are more aggressive than their wild counterparts. The movie details multiple instances where trainers were assaulted by captive orcas4. The movie makes the case that this is because being captive and being held in cramped tanks causes stress.

4. When orcas are young, their family are separated from them. Young orcas are separated from their family in the wild and sent to SeaWorld, as shown in the movie. The movie makes the case that doing this is inhumane and robs them of their social structure and natural environment.

The statement "The Lambert Azimuthal Equal Area Projection is an example of an equivalent projection commonly used in mapping today" is false.

While it is an example of an equivalent projection, it is not as widely employed as other projections like the Mercator projection or the Robinson projection.

The Lambert Azimuthal Equal Area Projection is designed to preserve area accuracy, meaning that the relative sizes of features on the map are preserved. However, it distorts shapes, angles, and distances, particularly as you move away from the center of the projection.

This distortion makes it less suitable for general-purpose mapping, where maintaining accurate shapes and distances is often crucial.

The Mercator projection, on the other hand, is a conformal projection that preserves angles and shapes, making it useful for navigation and presenting accurate shapes of landmasses. It is commonly used for world maps, particularly in navigation charts.

The Robinson projection is a compromise projection that attempts to balance size and shape distortions, resulting in a visually pleasing representation of the entire world.

While the Lambert Azimuthal Equal Area Projection may be used for specialized purposes or in specific regions, it is not as commonly employed as other projections due to its limitations in preserving shape and distance accuracy.

As mapping technologies and needs continue to evolve, cartographers and mapmakers choose projections that best suit the intended purpose and provide the most accurate representation of the Earth's surface.

The following statement is about synapses: neurotransmitters can bind to receptors on both sides of the synapse and cause ion-specific channels to open.

A synapse is a junction that allows a neuron to communicate with another cell. It is a tiny gap between two cells. This gap is known as the synaptic cleft. The action potential is converted into a chemical signal in synapses. The chemical signal is carried by a neurotransmitter that travels across the synaptic cleft to the postsynaptic membrane.

Once the neurotransmitter binds to its receptor, it induces a response in the postsynaptic neuron that can be either excitatory or inhibitory. Neurotransmitters at the synapse are coupled to ion-specific channels. This means that the type of receptor that the neurotransmitter binds to will determine which type of ion channel opens.

Neurotransmitter receptors at the synapse are coupled to ion-specific channels, not to receptors on both sides of the synapse. This statement is false. Thus, the correct answer is neurotransmitters can bind to receptors on both sides of the synapse and cause ion-specific channels to open.

b) each blade makes approximately 53 revolutions per minute.

(a) To find the angular speed of the fan in radians per minute, we can use the formula:

angular speed = linear speed / radius

We are given the linear speed of the tip of the blade as 7 feet per second, but we need to convert it to inches per minute to match the units of the radius. There are 12 inches in a foot and 60 seconds in a minute, so:

7 feet/second * 12 inches/foot * 60 seconds/minute = 5,040 inches/minute

Now we can plug in the values:

angular speed = 5,040 inches/minute / 15 inches = 336 radians/minute

(b) To find the number of revolutions a blade makes per minute, we need to convert the angular speed from radians per minute to revolutions per minute. There are 2π radians in one revolution, so:

revolutions per minute = angular speed / 2π

Plugging in the value we found for angular speed:

An example of organic solidarity would be a modern industrial society where individuals are interconnected and interdependent through their specialized roles and occupations.

Organic solidarity, as coined by sociologist Émile Durkheim, refers to a form of social cohesion that emerges in societies characterized by complex division of labor and specialization. In such societies, individuals have diverse roles and occupations, and their interdependence creates a sense of unity. Unlike mechanical solidarity, which is based on shared beliefs and values in traditional societies, organic solidarity is rooted in functional interdependence.

A modern industrial society serves as a prime example of organic solidarity. In such a society, individuals have specialized occupations and perform specific tasks necessary for the functioning of the whole. For instance, in a car manufacturing plant, workers in different departments like assembly, quality control, and logistics rely on one another to produce and deliver cars. Each individual's role contributes to the overall functioning of the organization, creating a sense of interconnectedness and mutual reliance.

This interdependence extends beyond the workplace. In modern societies, individuals rely on various services and professions, such as healthcare, transportation, and education, provided by others to meet their daily needs. The complex web of interconnected roles and occupations reinforces organic solidarity as people recognize their dependence on others to sustain their way of life.

Organic solidarity can be observed in modern industrial societies where individuals' interdependence, resulting from their specialized roles and occupations, fosters a sense of social cohesion.

In an Electrostatic Precipitator (ESP), the particle collection efficiency is typically expressed as the percentage of particles removed from the air stream.

Given that the ESP initially collects 95 percent of the particles, we can determine the new percent recovery when doubling the air flow rate while keeping the particle loading constant.

When the air flow rate is doubled, the residence time of particles passing through the ESP decreases, which can potentially affect the collection efficiency. However, since we're keeping the particle loading constant, it means that the number of particles entering the ESP remains the same even with the increased air flow rate.

Under the assumption that the ESP's collection efficiency remains constant regardless of the air flow rate, the new percent recovery can still be considered as 95 percent.

It's important to note that in real-world scenarios, the collection efficiency of an ESP may vary with changes in air flow rate, particle size, particle concentration, and other factors. Therefore, for accurate predictions or evaluations, it's recommended to consult specific ESP performance data or conduct experimental testing.

The process that maintained a stable Tasmanian devil population size involved a balance between birth rates, death rates, and population dispersal.

Tasmanian devils are marsupials native to Tasmania, an island off the coast of Australia. The stability of their population size can be attributed to several factors:

Birth rates: Tasmanian devils have relatively high reproductive rates. Females give birth to litters of up to 30 joeys, but usually, only 2-4 survive due to limited teats in the mother's pouch. The survival rate ensures that the population does not grow too rapidly.

Death rates: The death rates among Tasmanian devils are influenced by various factors, including disease, predation, and competition for resources. One significant factor affecting their population was the emergence of Devil Facial Tumor Disease (DFTD) in the 1990s. DFTD is a contagious cancer that spreads through biting during aggressive interactions, leading to high mortality rates. The disease caused a drastic decline in the Tasmanian devil population.

Population dispersal: Tasmanian devils have limited dispersal abilities due to their habitat confinement on the island of Tasmania. However, occasional dispersal events occur when individuals move to new areas in search of mates or resources. These dispersal events help maintain genetic diversity and prevent inbreeding within isolated populations.

The process that maintained a stable Tasmanian devil population size involved a balance between birth rates, death rates, and occasional dispersal. The high reproductive rates of Tasmanian devils, coupled with limited pouch space for joeys, helped control population growth. However, the emergence of Devil Facial Tumor Disease caused a significant decline in population numbers. The occasional dispersal of individuals allowed for genetic diversity and prevented inbreeding.

The process of transferring genetic information from DNA to RNA is known as transcription. It is a fundamental step in the central dogma of molecular biology, which describes the flow of genetic information.

Transcription is the process by which genetic information encoded in DNA is converted into RNA molecules. It plays a vital role in gene expression, allowing the information stored in DNA to be used for the synthesis of proteins. The central dogma of molecular biology outlines the flow of genetic information, stating that DNA is transcribed into RNA, and RNA is translated into proteins.

During transcription, a region of DNA called a gene is first unwound and separated. An enzyme called RNA polymerase binds to a specific region of DNA called the promoter and initiates the synthesis of RNA. The RNA polymerase moves along the DNA strand, reading the DNA sequence and building a complementary RNA molecule. The resulting RNA molecule called messenger RNA (mRNA), carries the genetic code from the DNA to the ribosomes, where it serves as a template for protein synthesis.

The correct answer choice that describes the path taken by excretory fluid through the mammalian kidney is as follows:

Renal artery: Excretory fluid enters the kidney through the renal artery, which supplies oxygenated blood to the organ.

Renal cortex: The renal artery branches into smaller arterioles, which lead to the renal cortex, the outer region of the kidney.

Glomerulus: Within the renal cortex, each arteriole forms a network of tiny blood vessels called the glomerulus. It is here that excretory fluid filtration occurs.

Bowman's capsule: The glomerulus is enclosed by Bowman's capsule, a cup-shaped structure that collects filtrate.

Proximal convoluted tubule (PCT): From the Bowman's capsule, the filtrate moves into the PCT, a twisted tubular structure where reabsorption of valuable substances like glucose, ions, and water occurs.

Loop of Henle: The filtrate then descends into the Henle loop, which consists of a descending limb and an ascending limb. The Henle loop plays a crucial role in concentrating urine and maintaining the balance of water and salt in the body.

Distal convoluted tubule (DCT): After the Henle loop, the filtrate enters the DCT, which further fine-tunes the reabsorption and secretion of substances based on the body's needs.

Collecting duct: The DCT connects to the collecting duct, which gathers filtrate from multiple nephrons. The collecting ducts merge and eventually lead to the renal pelvis.

Renal pelvis: The renal pelvis is a funnel-like structure that collects excreted fluid from the collecting ducts.

Ureter: From the renal pelvis, the excretory fluid flows into the ureter, a tube that transports the fluid to the urinary bladder for storage.

Urinary bladder: The urinary bladder temporarily stores excretory fluid until it is eliminated from the body through the urethra during urination.

This is a simplified overview of the excretory fluid's path in the mammalian kidney. It highlights the main structures involved in the filtration, reabsorption, and excretion processes.

In this scenario, wild type (v) is dominant to vestigial (v) wings, and brown (y) is dominant to yellow (y) bodies. The genes controlling these traits are linked. Flies that are true breeding for wild-type wings and brown bodies were crossed with flies that are true breeding for vestigial wings and yellow bodies.

The f1s were test crossed and the following offspring were observed: 356 wild-type wings, brown bodies; 8 wild-type wings, yellow bodies; 10 vestigial wings, brown bodies; 326 vestigial wings, yellow bodies. The total number of progeny is obtained by adding all the offspring, which is:

356 + 8 + 10 + 326 = 700

The number of recombinant progeny is the sum of the two classes of offspring that exhibit the recombinant phenotypes, which are the wild-type wings and yellow bodies, and the vestigial wings and brown bodies. These are:

8 + 10 = 18

Recombination frequency = (18 / 700) × 100

Recombination frequency = 2.6%

Therefore, the genetic distance between these two genes is 2.6 cM (centimorgans). Therefore, the answer is option D, 2.6.

Strong bright lights will cause sensory neurons to increase their firing rate while dim low lights will cause sensory neurons to decrease their firing rate.

Sensory neurons are specialized cells that transmit sensory information from the sensory organs to the central nervous system. These neurons respond to different stimuli, including light, and their firing rate is influenced by the intensity or strength of the stimulus.

In the case of strong bright lights, the sensory neurons will exhibit an increased firing rate. This increased activity is a result of the heightened stimulation from the intense light.

On the other hand, when exposed to dim low lights, sensory neurons will show a decreased firing rate. The reduced activity is a response to the lower level of stimulation provided by the dim lights.

Therefore, the firing rate of sensory neurons can be modulated by the intensity of the light stimulus, with strong bright lights increasing their firing and dim low lights decreasing their firing.
