Answer:
I think it would be C.Hot and bright
Explanation:
Because stars are usually hot and bright my bad if I'm wrong
The sequence of events in meiosis I is first 'chromosomes condense and crossing over occurs', second 'paired homologues align at the equator', third 'chromosomes are pulled to opposite poles', fourth 'separated homologues cluster at each pole' and fifth 'nuclear envelope re-forms around each daughter nucleus'.
Meiosis is a reductional cell division by which a parent cell produces four daughter cells with half of the genetic material.
Meiosis can be divided into meiosis I and meiosis II.
During prophase I (meiosis I),
- Begins the formation of the spindle apparatus from cytoskeleton present in the cytoplasm
- The homo-logous chromosomes pair and crossing over occurs. Crossing over refers to the interchange of genetic material between non-sister chromatids.
During metaphase I,
- The homo-logous chromosomes align at the equator plate of the cell
- The microtubules attach to the kinetochores of sister chromatids
During anaphase I,
- The chiasmata, which link homo-logous chromosomes together until anaphase I, are broken
- The homo-logous chromosomes are pulled to opposite poles, thereby, one chromosome of each pair randomly moves to one pole of the cell and the homologous chromosome to the other.
During telophase I,
- The separated homologous chromosomes cluster at each pole of the new cells
- The nuclear envelope is formed around each cell nucleus.

Answer:
Option d: black 75%, white 25%
Explanation:
The cross is between a homozygous black and a heterozygous black guinea pig
Parents gen. BB x Bb
F1 generation BB Bb Bb bb
The probability of an offspring with the same phenotype as its parents is
Genotype: BB - 25% and Bb - 50%, bb-25%
Phenotype: black 75%, white 25%
Answer:
The Calvin cycle requires the ATP and NADPH produced in the light-capturing reactions, while the inputs to the light-capturing reactions are regenerated by the Calvin cycle.
Explanation:
This process is fueled by, and dependent on, ATP and NADPH from the light reactions. Unlike the light reactions, which take place in the thylakoid membrane, the reactions of the Calvin cycle take place in the stroma (the inner space of chloroplasts).
