You are studying the source of new virus that has recently infected humans. You suspect that the virus was transferred from othe

r primates (they exhibit a similar infection), specifically chimpanzees, gorillas, or orangutans. You sample blood from several infected humans and sequence some viral genes. You then build a phylogenetic tree with the human sequences and all the known strains from each primate. Draw a hypothetical phylogenetic tree that would suggest that the virus came from gorillas, and this transfer occurred twice independently. Label chimp sequences (c), gorilla (g), orangutans (o), and humans (h).

In a plant called jimsonweed, flowers can be white or purple. A jimsonweed plant with white flowers is crossed with a jimsonweed
STALIN [3.7K]

<u>Answer:</u>

Although statements are not given in the question, we could make the most possible deduction as follows:

The allele for purple flowers is dominant whereas allele for white flowers is recessive.

<u>Explanation:</u>

According to the question,

  1. Purple flower plant was crossed with white flower plant.
  2. All offsprings have purple flowers.

Here we have one possibility that both parents were homozygous but in their own traits. <u>Purple flower</u> plants were "PP" and white <u>flower plants</u> were "pp" So, the <u>first progeny</u> (direct offsprings) would have "Pp". So, as per considerations, purple is dominant allele which will mask the recessive allele thus defining the color of all offsprings as purple. However, further cross of their generation will definitely end up into purple and white flowers (3:1) but this condition is not mentioned in the statement.

Photosynthesis is the process is specific to green plants and other photosynthetic organism converting light energy into storage energy by forming glucose from carbon dioxide and water and oxygen released as a byproduct.

This process involves the green pigment present in the plants called chlorophyll located in the chloroplast. The chloroplast is a double membrane organelle present in green plants. The membranes of the chloroplast are the site of photosynthesis.

Thus, the correct answer is option a. Membranes and chloroplast
