Biology
1 answer:
vazorg [7]3 years ago

Answer:

Epinephrine binds to receptors on some smooth muscles (ex: around arterioles) → Ca++ released from ER → intracellular Ca++ up → stimulates contraction. c. Epinephrine binds to receptors on some smooth muscles (ex: around bronchioles) → phosphorylates protein needed for response to Ca++, preventing response.

Answer:

c. carbon source

Explanation:

A "carbon source" refers to processes that<u><em> hastens carbon release into the atmosphere more than what they absorb.</em></u> Example of this is the burning of nonrenewable resources like fossil fuels.

The combustion of fossil fuels<em> increases the release of carbon dioxide.</em> Carbon is then being trapped into the atmosphere. This contributes to <em>"global warming."</em>

This is<u> opposite to</u><em><u> "carbon sink,"</u></em><em> </em>which absorbs most of the carbon than they emit.

Explanation on Mitosis​
Kipish [7]
Mitosis is the division that results in two “daughter” cells. Both of these daughter cells have the same number of chromosomes as the “parent” cell.
Mitosis consists of 4 phases: prophase, metaphase, anaphase, and telophase.
Prophase: the DNA is copied and the chromosomes pair up
Metaphase: the chromosomes line up in the middle of the cell
Anaphase: sister chromatids are pulled apart from each other towards opposite sides of the cell
Telophase: the cell begins to pinch in the middle and separates into two identical daughter cells
