Since you provided no answer choices, I will assume the correct answer choice is ANCESTOR. A cladogram begins with a common ancestor of all the organisms represented above.
The answers are A, B, & C. Steroid hormones have a
longer half-life than peptide hormones because steroid hormones ride on carrier
proteins in the blood. In other words, they
are bound to protein carriers that transport molecules across the membrane. They can also be stored temporarily in the adipose
tissue. And also, steroid hormones are sent to the nucleus where it regulates transcription
while peptides don’t require this process. This is the reason why the effects of
steroid hormones are exerted more slowly than peptides.
Answer:
First, the activity that humans execute that affects their ecosystem positively is reforestation. Second, the activity that humans execute that affects their ecosystem positively is hunting. Their effects rely completely in nature, however, one improves the ecosystem by making it greener and increasing the space nature has to grow, while the other impacts the ecosystem negatively by unbalancing the food chain.
Explanation:
The reasons behind this answer are that in the first place the ecosystem is a very sensitive environment that can be affected by a wide range of factors. In the first place, reforestation helps the environment have better conditions for the animals that live in it, as well as to provide the human race a better quality of air, water and feel better after living in a more natural ecosystem. While hunting breaks the ecosystem's balance because it allows the food chain of the ecosystem to break and allow a general modification.
