a neurosecretory cell in the hypothalamus.
Answer:
A. Water molecules are split.
Explanation:
The light dependent reactions of photosynthesis require the energy in sunlight to proceed. Structures called photosystems which contain chlorophyll absorb the light from the sun to generate excited electrons, which are transferred to electron carriers ATP and NADH.
These electron carriers are used in the light-independent reactions of photosynthesis.
During this process, the high energy electrons are passed to an acceptor molecule and replaced with an electron from water. This splitting of water produces H+ ions and oxygen as a byproduct. The splitting of water is called photolysis
Answer:
1. Part A: No
2. Part B: Yes
3: Part C : Yes
4: Part D : No
Explanation:
1) Part A: Facilitated diffusion of glucose into a muscle cell:
No; sodium ion co - transport is required for active transport of glucose but not for facilitated diffusion of glucose
2) Part B: Active transport of dietary phenylalanine across the intestinal mucosa:
Yes; co - transport of sodium ions drives the inward movement of amino acids and can only occur if sodium ions are actively pumped back out again.
3) Part C: Uptake of potassium ions by red blood cells:
Yes; uptake of potassium ions can occur only via a pump that couples the inward pumping of potassium ions to the outward pumping of sodium ions.
4) Part D: Active uptake of lactose by the bacteria in your intestine
No; active uptake of sugars and amino acids in bacteria is driven by a proton gradient.
Answer: the part of the brain that does decision making is different because adolescents arent fully grown
Explanation:
Answer:
mutation
Explanation:
occurs when a DNA gene is damaged or changed in such a way a to alter the genetic message carried by that gene. A mutation is an gent of substance that can bring about permanent alteration to the physical composition of a DNA gene such that the genetic message is changed
