why might changes to the gulf coast prairies and marshes ecoregion happen more quickly then to other ecoregion?
liq [111]
The reason for this is because it is closer to water, therefor they have more events that could happen. Also there is a lot of weathering, erosion, and deposition which makes the gulf coast prairies and marshes more susceptible to changes. 

I hope this helps!

The energy required to run the Calvin cycle reactions of photosynthesis comes from which two substances produced during the ligh
Lelu [443]

Answer:

a. ATP and NADPH

Explanation:

Light-dependent reactions of photosynthesis include splitting of water in the presence of sunlight and release of electrons. The electrons move from the reaction center of the PS-II via electron carriers to the PS-I. From the reaction center of PS-I, the electrons finally reach NADP reductase and reduce NADP into NADPH.

During this electron transfer via electron carriers, a proton concentration gradient is generated across the thylakoid membrane. The energy of this gradient is used to drive ATP synthesis. ATP and NADPH formed during the light-dependent phase of photosynthesis are then used during the reactions of the Calvin cycle.

Which of the following is true?
Arlecino [84]

During meiosis but not during mitosis, which of the following is true? __.

A haploid gametes are produced that are identical in their allelic composition

B the cytoplasm divides

C chromosomes line up in the center of the cell during metaphase

D genetic variation among the daughter cells is increased

E two identical daughter cells are produced

Answer:

D. genetic variation among the daughter cells is increased

Explanation:

Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. Meiosis occurs in germ cells, as a result; genetic variation among the daughter cells is increased. These cells (germ cells) are our sex cells – sperm in males, eggs in females.

In meiosis, the haploid gametes that are produced are not identical in their allelic composition.

In prophase 1, the chromosome pair up.

During metaphase, The chromosome pairs line up next to each other along the center (equator) of the cell.
