Answer:
A. Both waves carry energy and refract
Explanation:
There are two major types of waves viz; mechanical waves and electromagnetic eaves. Mechanical waves such as sound waves are waves that require a medium or matter to pass/travel through while electromagnetic waves like light waves do not strictly require a medium to travel i.e through vacuum.
Electromagnetic waves are transverse waves i.e their particles move perpendicularly to the direction of the wave while mechanical waves can either be transverse or longitudinal. All waves carry energy from one medium to another and are capable of refraction i.e. change of direction.
Therefore, both mechanical and electromagnetic waves carry energy and refract.

The earth rotates on its axis in a counterclockwise direction once every 24 hours, deflecting anything traveling long distances on or above the surface. This is known a the Coriolis Effect. What impact could the Coriolis Effect have on weather patterns
Answer:
in the Southern Hemisphere, currents are deflected to the left. As a result, storm systems seem to rotate clockwise. Outside storm systems, the impact of the Coriolis effect helps define regular wind patterns around the globe. As warm air rises near the Equator, for instance, it flows toward the poles.

1. What is the role of a receptor in helping an
organism maintain homeostasis?
A. receives messages sent by the control center
B. carries out a response to restore internal
conditions
C. detects stimuli and sends information to the
control center
D. compares current conditions with ideal values
for those conditions
Answer:
b
Explanation:
Homeostasis has been the tendency of the organism to maintain the equilibrium state. The stimuli are detected and transmitted to the control center by the receptors. Thus, option C is correct.
What is homeostasis?Homeostasis is the physiological process that monitors the internal environment of the body. This involves the feedback system that includes receptors that report and transfers the information to the control center of the body.
The receptor is involved in detecting the stimuli in order to generate the response through the feedback control system. The mechanism involves the effector that provides a response to the stimuli detected and transmitted by the receptors.
Therefore, in option C. the receptor sends information by detecting the stimuli.

Carbohydrates, proteins, and lipids are important molecules that make up the structure of the cell membrane. They help move materials into and out of the cell through the cell membrane
In what way is the cell membrane like a security guard?
Answer:
The cell membrane only alows certian materials to move through the membrane. Just like a security guard the membrane sorts through the good stuff and lets it past, but if someone or something bad comes along the security guard stops it. Just like the cell membrane.
Diffusion movement is always (h->L/L->H)

Ivan reads a story about a population of mice that become stranded in a dark jungle. Some mice are dark brown, while others are white. According to the process of natural selection, predict which mice would be more successful living in a dark jungle. Explain natural selection and your prediction.
Answer:
The dark brown mice would be more successful in a dark jungle since the darker color of their fur would make it hard for predators to spot them.
The process of natural selection, predict which mice would be more successful living in a dark jungle is de dark brown.
What is natural selection?Natural selection is one of the main mechanisms of evolution. In a very simple way, we can say that natural selection is a process in which the fittest organisms are selected, survive in the environment, reproduce and pass their characteristics on to their descendants.
In this case, as it is a very dark forest, an animal with a white coat will attract more attention while an animal with a dark brown color will only be camouflaged in the environment.

Which of the following is not a key ingredient in cloud formation?
particles. drizzle. water vaper. drop in air pressure
Answer:Drizzle
Explanation:
Clouds require water vapor, particles the vapor can condense around, and a drop in air pressure to form.
Cloud formation is a process that begins with a drop in air pressure. An ingredient that is not key in the formation of clouds is;
A. DrizzleDrizzle is not an important factor in the formation of clouds. Clouds are formed when water and ice are suspended in the air.
The process of cloud formation begins when the terrain is heated up by the sun.
Wind blows more around the areas of low pressure thus causing the rising of warm air which holds up water.
After some time, this air becomes condensed and falls down as rain.
Summarily, Drizzling is not an important part of cloud formation.

Answer:
B. The first generation will not have short plants. The short trait will return in the second generation.
Explanation:
If T is for Tall and t is for short, then the first generation doesn't have any short offspring. We can rule out answer choices A and D.
The second generation results in TT, Tt, Tt, tt.
TT is a tall Offspring.
Tt is a Tall Offspring, with a small t as a recessive trait.
tt is a short offspring because both the recessive traits (t) are together.
We can rule out option C.
That leaves us with the correct answer being B. The first generation will not have short offspring, but will pass it on to the second generation, which will have a short offspring (25% chance of having short offspring).

Answer:
This type of natural selection occurs when there are selective pressures working against two extremes of a trait and therefore the intermediate or “middle” trait is selected for. If we look at a distribution of traits in the population, it is noticeable that a standard distribution is followed: Example: For a plant, the plants that are very tall are exposed to more wind and are at risk of being blown over. The plants that are very short fail to get enough sunlight to prosper. Therefore, the plants that are a middle height between the two get both enough sunlight and protection from the wind.
This type of natural selection occurs when selective pressures are working in favour of one extreme of a trait. Therefore when looking at a distribution of traits in a population, a graph tends to lean more to one side: Example: Giraffes with the longest necks are able to reach more leaves to each. Selective pressures will work in the advantage of the longer neck giraffes and therefore the distribution of the trait within the population will shift towards the longer neck trait.
This type of natural selection occurs when selective pressures are working in favour of the two extremes and against the intermediate trait. This type of selection is not as common. When looking at a trait distribution, there are two higher peaks on both ends with a minimum in the middle as such: Example: An area that has black, white and grey bunnies contains both black and white rocks. Both the traits for white and black will be favored by natural selection since they both prove useful for camouflage. The intermediate trait of grey does not prove as useful and therefore selective pressures act against the trait.
Genes help to define who an individual is inside and out. In addition to visible traits like weight and eye color, psychological qualities such as personality traits, intelligence, risk of mental illness, and more have been linked to genetics.
