Small rocky bodies that revolve around the sun are asteroid's
You can reduce the risks of radiation exposure by:
1. Eating foods that contain chlorophyll. Foods that contain this substance detoxify the blood, helping to remove all kinds of nasty toxins including radiation.
2. Ingest sea vegetables. Kelp, dulse, and agar contain natural iodine, which protects against radioactive iodine found in foods like dairy products.
3. Supplement with bee pollen. It can protect your body against x-ray induced radiation sickness.
4. Limit daily exposure to nonionizing radiation.
Answer:
The species that will be most similar to humans will be
1. rhesus
2. pigeon
3. fruit fly
Explanation:
Evolution can be described as the process in which different organism evolve from common ancestors over a long period of time. Evolutionary studies show that some organisms have more shared characteristics as compared with other organisms. These organisms with common characteristics are believed to be closer to one another and evolved from the same ancestors.
In the above question, as there is only one difference between the cytochrome c of humans and rhesus, hence rhesus is the closest to humans. Pigeons has lesser number of differences than fruit fly, hence it is second on the list. Fruit fly has the maximum differences hence it is placed last.
Question in English:
A female carries a recessive lethal gene (l) on one of her X chromosomes, and a normal dominant allele (L) on the other. What is the sex ratio to be expected in this woman's dependency if she marries a normal man?
Answer:
2/3 females
1/3 males
Explanation:
Females have two X chromosomes (XX) and males have an X and a Y chromosome (XY).
The genotype of the female is XLXl. The genotype of the male is XLY, since he is normal.
The possible genotypes are:
<u> XL Xl</u>
<u>XL</u> <em>XLXL XLXl</em>
<u>Y</u> <em>XLY </em><em>XlY</em>
<em />
All female offspring will be normal as they will always have one normal copy of the X chromosome from their father.
50% of the male offspring will be normal, but 50% will inherit the lethal gene from their mother.
Because the allele is lethal, that means XlY males will not be born.
That means 2/3 of the children will be females, and 1/3 will be males.
