Answer:
C: autocrine
Explanation:
There are three types of hormones according to where their target cells are.
- Endocrine: Their target cells are distributed far and they travel via blood to reach the target cells.
- Paracrine: Their target cells are often their neighbors so they often diffuse to reach them
- Autocrine: Their secretion acts on themselves. Hence they are their own targets.
The energy role of a grizzly is that is is a omnivorous consumer because it is not a producer.
A grizzly bear's diet consist of both plants and animals as it relies on the food it eats for energy consuptions. It is incapable of producing energy with photosythesis, hence it is not a producer.
Many different ways, primarily through bone and muscle loss. The lack of pressure on bones causes the body to reabsorb calcium from them, weakening them and potentially causing kidney stones.
Answer:
The conditions that would cause a molecule to diffuse from outside to inside of a structure is a higher concentration of that molecule outside and the presence of a semipermeable membrane that facilitates its passage.
Explanation:
The process by which a molecule passes from a place where it is more concentrated where its concentration is lower - crossing a semipermeable membrane - is called simple diffusion.
<u>Simple diffusion is a mechanism that does not require energy and responds to a concentration gradient</u>. When a molecule is more concentrated in a space it can enter the space where it is less concentrated
.
The cell membrane is an example of a semi-permeable membrane where the simple diffusion process occurs.
