The given question is incomplete as the group of choices lack the correct answer, however, the correct group of choices are as follows:
A. Movement of sister chromatids to opposite poles at anaphase II of meiosis.
B. Movement of homologous chromosomes to opposite poles at anaphase I of meiosis.
C. Crossing over between homologous chromosomes during prophase I of meiosis.
D. Replication of chromosomes prior to meiosis.
E. Independent alignment of different homologous pairs on the metaphase I spindle.
Answer:
The correct answer is : Movement of homologous chromosomes to opposite poles at anaphase I of meiosis.
Explanation:
The Mendel's law of segregation says that during formation of gametes the copies of genes segregate from each other so each gamete has equal and only one allele of the gene.
This behavior of homologous chromosome can be seen in anaphase I in meiosis, responsible for the segregation of copies of allele into different copies.
Thus, the correct answer is : Movement of homologous chromosomes to opposite poles at anaphase I of meiosis.
Progressive degeneration of the retina that affects night and peripheral vision is known as retinitis pigmentosa.
<h3>
What is retinitis pigmentosa?</h3>
- A collection of uncommon eye conditions known as retinitis pigmentosa affect the retina.
- Retinitis pigmentosa causes the retinal cells to gradually deteriorate over time, resulting in visual loss.
- RP is a hereditary condition that affects people at birth.
- The term "retinitis pigmentosa" (RP) refers to a group of illnesses that affect the retina's light-sensitive cells and impair vision.
- There is currently no medication to stop the course of the disease, nor is there a cure.
- Night blindness and tunnel vision are symptoms.
- Retinitis pigmentosa has no specific treatment.
- However, using UV sunglasses to protect the retina in your eyes may help postpone the onset of symptoms.
- For people with very advanced disease and severe visual loss, a retinal prosthesis (artificial retina) has been developed.

Chloroplasts
In plants and algae, which developed much later, photosynthesis occurs in a specialized intracellular organelle—the chloroplast. Chloroplasts perform photosynthesis during the daylight hours. The immediate products of photosynthesis, NADPH and ATP, are used by the photosynthetic cells to produce many organic molecules. I have taken the test before
Answer:
From what I remember in my 9th grade biology class, it's usually half that amount.
