Answer 2

Answer:

When antibodies attach to an antigen (think a lock–key configuration), it signals other parts of the immune system to attack and destroy the invaders. This is how the human body develops immunity (acquired) to a particular disease. But some germs and viruses are very adaptive.

ow do cells use food to make energy and maintain homeostasis

Answers

Answer:

Cells obtain energy through the process of cellular respiration. It is a metabolic process of conversion of the biochemical energy from the nutrients into adenosine triphosphate (ATP). ... They exchange substances with the new cells and also eliminate the wastes thereby maintaining homeostasis.

Explanation:

There are several ion transport mechanisms within the cell membrane that function to maintain proper levels of solutes inside and outside the cell. ... This system uses the energy stored in ATP to pump potassium into the cell and sodium out of the cell.

When the particles are equally spaced apart they have reached:
A. Hypertonicity

B. Dynamic Equilibrium

C. Homeostasis

D. Osmolarity

Answers

Answer:

B. Dynamic Equilibrium

Explanation:

Since the molecules are still in motion, but an equilibrium has been established, the end result of molecular diffusion is called a "dynamic equilibrium". The end result of diffusion is an equal concentration, or equilibrium, of molecules on both sides of the membrane. At equilibrium, the movement of molecules does not stop.

Answer:

B. Dynamic Equilibrium

Explanation:

When the particles are equally spaced apart they have reached the dynamic Equilibrium.

A toad is brought into a new ecosystem. It is stronger than the toads that
already live there and reproduces quickly. Which is the best way to describe
these toads in the new ecosystem?
A. Invasive species
B. Native species
C. Keystone species
D. Cyclical species

Answers

Answer:

a

Explanation:

newer, stronger, and reproduces more

this means that the other animals would have to compete and they usually lose.

Invasive species is the best way to describe toads in the new ecosystem. Therefore, option (A) is correct.

What are invasive species?

Invasive species are non-native organisms that are introduced to an ecosystem and have negative impacts on the environment, economy, or human health. They typically outcompete native species, reproduce quickly, and lack natural predators in the new ecosystem.

The fact that the toad is stronger than the toads already living there and reproduces quickly suggests that it may outcompete native toads for resources and space. This could potentially lead to a decline in the population of native toads, which could have negative effects on the ecosystem.

Answer:

[tex]\huge\boxed{Answer\hookrightarrow}[/tex]

It doesn't depend on whether the seal is a mammal or not. A seal has a thick layer of fat - 'blubber' that helps them to stay warm in the cold polar seas. This layer of fat or blubber is not found in humans as we live in warmer areas & hence don't have a need for it. So, humans will die in the cold polar seas without extra protection unlike seals.

Explanation:

The main function of carbohydrates is to provide energy and regulation of glucose in the blood.  It prevent the use of proteins for production of energy and also promote breakdown of fatty acids and preventing ketosis. Ketosis is a process that occurs when our body doesn't have carbohydrates in sufficient quantity for the production of energy. Carbohydrates are the first biomolecules that are used for energy production.

Will mark as brilliant answer

Answers

Answer:

Below :D

Explanation:

So basically, this question is asking what will cause a species' population to reach a point where it stops increasing.

Lets think about what can cause a lack of increase?

A decrease can cause this.

Or a slow in the rate of increase.

Now lets look at our selectable answers and see if any of them would fall under these two things.

First up is fewer deaths.

Well, fewer deaths basically means less of a decrease in population.

This is the opposite of decreasing the populatin count, and would instead raise it.

Next we have a limit in food supply.

This would cause a organism to starve and die.

So this would cause a decrease in population count.

So B is one of the answers

Next up is competition with other species.

When two species compete for a sort of resources, one massivly dies out due to outcompetion, and loses the resources needed to survive.

So this would also cause a large decrease in population count.

This makes C one of the answers

Next is increase in birth rates.

This would cause more organisms to be born of a species, basically increasing the population count.

This is the opposite of a decrease in  population.

Next we have competition for space.

This is very similar to answer C, and the outcompeted species dies out due to lack of space.

So E is one of the answers

Now, the next answer seems viable, because major storms can kill off organisms, like hurricanes, earthquakes, and volcanos for instance.

However, as seen in many organisms over history, while these major storms kill of organisms, they can recover.

So although major storms decrease populations, they dont actually limit them.

In the end:

B is correct

C is correct

E is correct

Hope this helps!
