Some characteristics of plants that typically grow in the early and late stages of secondary succession are high respiration and photosynthesis.
<h3>Early and late stages of secondary succession plants?</h3>
Early succession plants are plants that exist or plants that sprout before any activity on farmland, they usually have a high rate of resource intake.
Typical examples are the weeds and grasses

Answer:
A. The synthesis of triose phosphates from 3-phosphoglycerate
Explanation:
ATP and NADPH are produced during light-dependent reactions of photosynthesis in chloroplasts. These molecules serve as an energy source and reducing power respectively during the Calvin cycle. Calvin cycle includes fixation of carbon into 3-PGA followed by reduction of 3-PGA into glyceraldehyde 3-phosphate (a triose phosphate).
The reduction step also uses NADPH as an electron donor. Two molecules of glyceraldehyde 3-phosphate make one molecule of glucose. A reduced ATP production during light-dependent reactions in chloroplast would not allow the reduction of 3-PGA into glyceraldehyde 3-phosphate. Without the formation of triose phosphate, glucose synthesis will also reduce.
Yes, I agree with statement b/c in meiosis I, specifically in prophase I the homologous chromosomes line and form tetrads in which they exhibit the act of ‘crossing over’ which allows for genetic diversity; This would not occur in mitosis as body cells are produced to repair or for growth so the division of cells must allow for the exact replication of DNA or it is not possible to repair the body or growth if there is genetic variation in each cell. Also, in Meiosis I, specifically when metaphase I occurs, it is impossible to predict how the homologous chromosomes will be split, therefore creating even more diversity of genes known as Independent assortment. None of these processes occur in meiosis II, as the exchange of DNA and act of genetic diversity has already occurred in Meiosis I, therefore Meiosis II simply has to go throwing regular cell division making it more similar to mitosis than Meiosis I; Independent assortment and crossing over are the processes that set Meiosis I to differ from the others.
