Steroid hormones ________. begin their action outside the membrane usually diffuse through the plasma membrane into target cells bind to receptors in the plasma membrane are water soluble

Answers

Answer 1
Answer:

Steroid hormones usually diffuse through the plasma membrane into target cells. Thus, the correct option for this question is B.

What are Steroid hormones?

Steroid hormones may be defined as a type of hormones that are synthesized in the adrenal cortex, the gonads, and the placenta. They are all derived from cholesterol and many are of clinical importance. Steroid hormones are synthesized in the mitochondria and smooth endoplasmic reticulum.

According to the context of this question, lipid-derived (soluble) hormones such as steroid hormones diffuse across the membranes of the endocrine cell. Once outside the cell, they bind to transport proteins that keep them soluble in the bloodstream.

Therefore, steroid hormones usually diffuse through the plasma membrane into target cells. Thus, the correct option for this question is B.

What's happens to biomass as you move up the biomass pyramid

Answers

Answer;

The biomass and energy decreases as you move up the biomass pyramid.

Explanation;

  • Biomass is the mass of material in living organism. It is usually measured as dry mass of biological material in grams. A biomass of organisms at different levels of a food chain can be shown in a pyramid of biomass.
  • The biomass of in each trophic level is always less than the trophic level below because not all organisms at one stage are eaten by the same stage above. Some material and energy is passed out as waste by the organism. Some of the energy is used for growth.
  • Therefore, biomass and energy decreases as you move up the biomass pyramid from one trophic level to the next.
the amount of energy decreases. the top of the pyramid always has the least amount of energy and the bottom of the pyramid has the most amount of energy.

A finite resource in the environment that keeps a population from steadily increasing is known as?

Answers

Answer;

Limiting factor.


A finite resource in the environment that keeps a population from steadily increasing is known as Limiting factor.


Explanation;

If the presence or absence of a factor limits the growth, abundance, or distribution of the ecosystems elements, it is called a limiting factor.

There are several abiotic factors (non living factors) that limit ecosystem growth, including temperature, precipitation, sunlight, soil configuration, and soil nutrients.

This would be a "limiting factor." To limit means to restrict, which is what happens when one of these factors prevents the population from steadily increasing.
