Answer:
A stellar-mass black hole forms when a star with more than 20 solar masses exhausts the nuclear fuel in its core and collapses under its own weight. The collapse triggers a supernova explosion that blows off the star's outer layers.
Explanation:
Answer:
- In glycolysis, glucose is split into two pyruvate and makes some ATP
- The Krebs cycle produces ATP, NADH and CO2
- NADH gives electrons to the ETC
- As electrons move down the ETC, a H+ gradient is made
- H+ pass through the ATP synthase to make ATP
Explanation:
This question is describing the processes involved in cellular respiration. Cellular respiration is the way through which living cells synthesize energy (ATP) by breaking down sugar. Cellular respiration involves three major steps: glycolysis, Krebs cycle, and oxidative phosphorylation (electron transport chain).
- Glycolysis is the process whereby glucose is broken down into pyruvic acid or pyruvate with the synthesis of net 2 ATP molecules.
- Kreb's cycle produces ATP, NADH and CO2.
- NADH is an electron carrier that donates electrons to the Electron transport chain (ETC).
- Electrons move down the ETC to produce a proton (H+) gradient
- The proton (H+) passes through an enzyme called ATP synthase to make ATP from ADP molecule.
B I think(sorry if you get this wrong)
Answer:
The description indicates that Genetic variation is decreasing
The reasoning is that SEM is progressively smaller
Explanation:
Genetic variation decreases when organisms mate between relatives
