Explanation:
The breaking of a large organic molecule into smaller individual subunits involves multiple ________. dehydration synthesis reactions osmotic reactions hydrolysis reactions hydrosynthetic reactions
Answer:
hydrolysis reaction
Explanation:
Hydrolysis reactions are the reverse of condensation reactions. In a hydrolysis reaction, a larger molecule forms two (or more) smaller molecules and water is consumed as a reactant. Hydrolysis ("hydro" = water and "lysis" = break) involves adding water to one large molecule to break it into multiple smaller molecules.

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.

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.

How is climate change being impacted?
More frequent and intense drought, storms, heat waves, rising sea levels, melting glaciers and warming oceans can directly harm animals, destroy the places they live, and wreak havoc on people's livelihoods and communities. As climate change worsens, dangerous weather events are becoming more frequent or severe.
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.

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.

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.

DNA damage can affect normal cell replicative function and impact rates of apoptosis (programmed cell death, often referred to as 'cellular senescence'). Alternatively, damage to genetic material can result in impaired cellular function, cell loss, or the transformation of healthy cells to cancers.
