In ecosystem, Killer whales are apex predators, which means they have no natural predators.
What do you mean by apex predators?An apex predator, also known as a top predator, is a predator at the top of a food chain, without natural predators of its own. Apex predators are usually defined in terms of trophic dynamics, meaning that they occupy the highest trophic levels.
In the natural sciences, an apex predator is a predator that exists at the very top of the food chain. Unlike some other predators, it's never preyed upon itself. Examples include polar bears, lions, crocodiles, and orcas.
There are some “apex” predators that are found throughout much of the world, including grey wolves, blue whales, killer whales and great white sharks. In my mind, however, humans are clearly the overall apex predator of the world. We've even been called the super-predator.

What is Desert biome?
The driest biomes are the desert ones. In actuality, a desert's primary distinguishing feature is how little rain it gets. Compared to rainforests, which receive over 2,000 mm annually, most deserts receive less than 300 mm.
Hence, the desert only receives 10% of the rainfall that a rainforest does. Because the air is so dry and heat escapes so quickly at night, the temperature in the desert can vary significantly from day to night.
The average daily temperature is 38°C, while at night, it can fall as low as -4°C in some desert regions. The location of the desert has a significant impact on the temperature as well.
Therefore, Grass, star cactus, and cactus are food web.

describe the two forces that control the speed at which fragments pass through the gel
The two forces that control the speed at which fragments pass through the gel in Gel electrophoresis is frictional force of agarose gel and the electrostatic force by the electrical field.
Gel electrophoresis is method of separating molecules by the size and electric field. It is common technology used in genetic engineering. The DNA is cut up into small fragments using restriction enzymes. The molecules are forced to move along the agarose gel by applying an electric field.
The fragments separates based on the size. The bigger fragments moves slower. The frictional force of the agarose gel oppose the movement of the fragments. The electrical field provides the electrostatic coulomb force, to move the particles. More the electrical field strength, the fragments move faster.
The other factors that affects the speed is shape of the molecule, the strength and temperature of the buffer etc.
So the forces that control the movement of fragments are Electrostatic coulomb force and frictional force.

when will greenhouse gases have the biggest impact on atmospheric temperatures? why then and there?
Greenhouse gases have the biggest impact on atmospheric temperatures when they are at their highest levels.
This is due to the fact that larger concentrations of greenhouse gases trap more heat in the atmosphere, raising world average temperatures.
The "greenhouse effect" is created by increasing concentrations of carbon dioxide, methane, and other gases in the atmosphere, which behave like a blanket in the atmosphere, trapping heat and warming the globe.
Due to the melting of glaciers and ice sheets, this might cause more extreme weather conditions, such as heat waves and droughts, as well as an increase in sea level.
More air pollution and health concerns associated with climate change can result from the atmosphere's composition being altered by higher amounts of greenhouse gases.
The most heat is trapped and the most substantial changes in the climate are visible when greenhouse gas concentrations are at their peak, which has the most influence on atmospheric temperatures.

the process by which co2 (and then carbon) is added to intermediate and deep-ocean water and the ocean bottom, through the involvement of photosynthetic organisms, is called the ______.
The biological pump is the mechanism through which CO2 (and then carbon) are added to intermediate and deep ocean water as well as the ocean floor by photosynthetic organisms.
Seawater's pH is lowered as a result of the oceans absorbing roughly 30% of the carbon dioxide (CO2) that we produce. We call this phenomenon "ocean acidification." Whenever air meets water, the ocean takes carbon dioxide from the atmosphere. Water has greater opportunities to absorb carbon dioxide when there are waves and turbulence, which are brought on by wind.
Like land animals, fish and other oceanic creatures also breathe oxygen and exhale carbon dioxide (CO2). The concentration of hydrogen ions increases as a result of a series of chemical reactions that take place when CO2 is absorbed by saltwater.

Question 11 (1 point) If a bacterium adapted to a cold environment were moved to a much warmer environment, what changes to the membrane lipids should the bacterium make? Because increased temperature decreases fluidity, the bacterium should increase the length of fatty acid tails on membrane lipids Because increased temperature increases fluidity, the bacterium should decrease the length of fatty acid tails on membrane lipids Because increased temperature decreases fluidity, the bacterium should decrease the length of fatty acid tails on membrane lipids Because increased temperature increases fluidity, the bacterium should increase the length of fatty acid tails on membrane lipids
A bacteria that has evolved to a warm environment should shorten the length of the fatty acid tails on its membrane lipids if it is placed in a significantly cooler environment.
A sort of unicellular organism that is a member of the genus bacteria is called a bacterium. Unlike plants and humans, bacteria typically have a single cell and smaller cells. They can be found in a variety of habitats, such as soil, water, and other living things.
The reason for this is that as it gets colder, the membrane loses fluidity; however, longer fatty acid tails can help to prevent this. The bacteria can enhance the amount of van der Waals connections between nearby fatty acid tails by lengthening their tails, which helps to stabilize and maintain the fluidity of the membrane. The bacterium's modification would increase its functionality and enable it to endure the colder climate.

does the lung inflate part by part or as a whole, like a balloon?
The lung inflates as a whole, like a balloon. The process of exhalation is also a whole-lung process, in which the diaphragm and other muscles relax, causing the volume of the thoracic cavity to decrease.
During inhalation, the diaphragm and other muscles contract, causing the volume of the thoracic cavity to increase. This increase in volume causes a decrease in air pressure in the lungs, and air is drawn in to equalize the pressure. The air fills the airways and the alveoli, small air sacs in the lungs where gas exchange takes place.
As the lungs fill with air, they expand as a whole, rather than inflating part by part. The pleural membranes that surround the lungs allow them to expand and contract easily within the thoracic cavity, so that the entire lung inflates and deflates with each breath.
This decrease in volume increases air pressure in the lungs, and air is forced out of the airways and alveoli. Again, the whole lung deflates as a single unit.
