Answer:
Nuclear Fusion
Explanation:
The Sun gets its energy from the process of nuclear fusion. This process occurs in the sun's core or interior
Answer:
A mixture
Explanation:
The elements of a mixture combine physically, yet there is no chemical reaction
I think the answer you’re looking for is hydrogen bonding or dipole dipole interactions. These interactions happen between molecules that are polar. Meaning their atoms don’t share their electrons equally and one’s more electronegative than the other one.
Hope this helps:)
When the kidney's own blood supply decreases, they release<u> renin, </u>which leads to secretions of aldosterone from the adrenal cortex.
Renin is an enzyme produced by certain kidney cells. It is a component of the renin-angiotensin-aldosterone system, which regulates blood pressure through a chain of reactions. Specifically, renin regulates the adrenal glands' synthesis of the hormone aldosterone.
- Renin transforms angiotensinogen (a liver-produced precursor to angiotensin) into angiotensin I. Angiotensin is a hormone that causes constriction of the blood vessels.
- Angiotensin I is then converted to angiotensin II. Angiotensin II constricts blood vessels and promotes aldosterone release.
- Aldosterone helps the kidneys retain water and salt, thereby boosting the body's water content. This causes the blood pressure to rise.
