They play huge role in organisms, every living organism needs proteins.
- enzymatic role ( they build enzymes which lower an activation energy in reactions and increase reaction speed)
- hormonal role (they build hormons)
- structural role (for example keratin)
- transport role ( for example hemoglobin)
- energetic role ( for example aleurone grains in plant cells or they are used to gain energy in human organism when it's out of lipids and carbohydrates)
These are known as Hormones. Hormones are chemical messengers that are released in one tissue normally endocrine glands for example, adrenal glands, pituitary glands, and transported in the blood stream to alter the activities of specific cells in other tissues. Hormones serves as messengers, controlling and coordinating activities or processes such as growth, metabolism and fertility in the body.
D is the answer of transportation
Answer:
This is what I put (its kinda bad so don't judge)
Explanation:
A) Examining Table 1 with cancerous cells and HeLa cells we can see that with both HeLa and cancerous cells when treated with EGF increase in cells. Examining Table 2 we can see that HeLa cells create the most cells when treated with a concentration of 25 ug of EGF.
B) Normal cells increased by 33 when treated with a concentration of 10 ug of EGF. Cancerous cells increased by 405 when treated with a concentration of 10 ug of EGF. We can conclude from this that the cancerous cells multiply faster than normal cells with a concentration of 10 ug of EGF.
C) The mitotic index of HeLa cells with zero EGF treatment is 11 mitotic figures noted per 73 high power fields. The mitotic index of HeLa cells with 10 ug of EGF treatment is 8 mitotic figures noted per 90 high power fields. The mitotic index of cancerous cells with zero EGF treatment is 22 mitotic figures noted per 60 high power fields. The mitotic index of cancerous cells with 10 ug of EGF treatment is 27 mitotic figures noted per 465high power fields.
I'm on D right now so I'll put that in when I'm done with it
