Irradiated mice given a stimulatory antigen fail to mount an adaptive immune response. A robust response can be restored by:
Answer:
A bone marrow transplant (BMT)
Explanation:
An irradiated mouse would have immune hypocellularity or acellularity. A BMT would replenish its immune system to mount a robust immune response.
How is a proton gradient formed across the inner mitochondrial membrane?
Answer:
Energy is released in these “downhill” electron transfers, and several of the protein complexes use the released energy to pump protons from the mitochondrial matrix to the intermembrane space, forming a proton gradient.

Which of the following statements apply to leukocytes? Select all that apply.
Multiple select question.
They eject major organelles when mature.
They are capable of protein synthesis.
They live approximately 120 days.
They retain their organelles throughout their life time.
They are not uniform in form and function.
Explanation:
leukocytes are white blood cells. mainly 4 killing bacterial infections.
Leukocytes are the specialized cells which are a part of blood. These are known as white blood cells. These protects the body. These produce antibodies. Thus, the correct options are B, D, and E.
What are Leukocytes?
Leukocytes are the white blood cells. These are a type of specialized cell type which is present in blood along with erythrocyte and plasma. Leukocytes are primarily responsible for protecting the body from pathogens and germs by producing antibody proteins which fight against these organisms.
Leukocytes are irregular in shape. They can change their shape to engulf or kill the bacteria which enters the blood to prevent disease. Erythrocytes change their shape which allows them to pass through the capillaries which are very tiny.
Therefore, the correct option is B, D, and E.

What does the graph tell you about the concentration of salt inside the cell?
Answer:
So,
Assuming that the plasma membrane is either semipermeable or fully permeable, either diffusion or osmosis will even out the concentration eventually. Therefore, options A and B are eliminated.
The only options left both say that osmosis will take place. We know that osmosis will always move the solvent from an area of low solute concentration (outside the cell) to an area of high solute concentration (inside the cell). Thus, water will move into the cell through osmosis. That is option C.
If the cell cannot get rid of the water quickly enough, the cell will explode by cytolysis.

Fracking uses highly pressurized fluids, such as water mixed with sand and chemicals, to drive open cracks that exist in underground rock. Which statement
best describes an environmental consequence of this process for ecosystems?
O Wastewater is contaminated with oil and becomes sludge in landfills
O Water vapor is released into the air, which is considered a greenhouse gas,
Heavy metals are released into surrounding soil, poisoning local vegetation
O Billions of gallons of water are pulled from surrounding areas
The correct answer is that chemicals added to the liquid can contaminate groundwater.
Fracking is a method of drilling fossil energy resources, which requires a lot of water and consumes local water resources. It is pumped with high pressure water, sand and chemicals, causing high pressure to block the porous rock and release gas.
The water spill itself destroys nature from the drilling site, and may even cause earthquakes, especially due to the pumping of abundant wastewater into porous rock types such as limestone. For example, Oklahoma appears to have become a special earthquake risk area. The biggest impact of water distortion is on groundwater. In Wyoming, USA, the same chemicals found in groundwater have been found in groundwater, and some of them are toxic or carcinogenic.

Answer:
Statements thar are true:
Some organisms have phenotypes that make them better increase chances of reproduction.
Natural selection continues to occur even today
Phenotypes found In the most successful members of a species become the most prevalent after several generations.
Explanation:
It is not true that all organisms must compete for survival, sometimes the conditions are good and there is enough food or good climate conditions and that makes no need of competition an increase in the individuals of the species.
Animals undergo natural selection, this is a random natural phenomenon that can make plants and animals adapt better or worse to the enviromental conditions. This cause that the beneficiaries can adapt, survive and reproduce and became the most prevalent after generations.
Mutations are not phenomen that occur because the living being needs it, but rather they are phenomenon that occur at random at any time and determine the possibility of survival.
A decrease in food availability will do the contrary, decrease the variation in a population because it makes that only those who manage to adapt to eat another food survive, for example.
