Why does the moon have a greater influence on Earth's Tides than the sun does
Answer:
Because ocean tides are the effect of ocean water responding to a gravitational gradient, the moon plays a larger role in creating tides than does the sun. But the sun's gravitational gradient across the earth is significant and it does contribute to tides as well.

Which of the following statements regarding selenium/selenoproteins is incorrect?
a. They are proven protection against colon cancer.
b. The amount of selenium in foods depends upon the soil where the plants were grown and animals grazed.
c. Selenium functions as an antioxidant.
d. Selenium plays an important role in the regulation of thyroid hormones.
Answer:
The correct answer is: A. They are proven protection against colon cancer.
Explanation:
Selenium is a mineral that can be incorporated into our bodies in small amounts when we consume certain foods, such as whole grain and dairy products. The amount of selenium in these products depends on the soil where the plants and animals were.
Selenium plays an important role as an antioxidant, which can lower the risk of developing several types of cancer. However, this doesn't mean that its consumption can prevent colon cancer, and the studies that had been done to prove its effectivity in these regards have been inconclusive.
Besides functioning as an antioxidant, selenium also is very important for the regulation of the thyroid hormones, which play an important part in metabolism.
The protein that contains selenocysteine amino acid remnants is called selenoproteins. They are found in the endoplasmic reticulum of the cells.
The incorrect statement is:
Option a. They are proven protection against colon cancer.
The statement can be explained as:
Selenium is a mineral that gets incorporated into our body through foods, dairy and whole grains. The amount of selenium depends on its amount and presence in the soil.Selenoproteins are good antioxidants that can lower the risks of cancers. But its consumption does not provide complete protection against cancers.It also regulates the thyroid hormone and plays a vital role in the regulation of metabolism.Thus, they have not proven medication for colon cancer.

Anya and Greg are working in their research laboratory. Anya tells Greg that one of the mice has a 50% probability of having the alleles DD and a 50% probability of having the alleles Dd. How can Anya explain her reasoning? In two out of 50 times, the mouse has the alleles DD or Dd. The probability that the mouse has the alleles DD is equal to the probability that it has the alleles Dd. The mouse is twice as likely to have the alleles DD than it is to have the alleles Dd. There are two more possible outcomes besides the mouse having DD or Dd alleles.
Answer:
Option B: The probability that the mouse has the alleles DD is equal to the probability that it has the alleles Dd.
Explanation:
Anya tells Greg that one of the mice has a 50% probability of having the alleles DD and a 50% probability of having the alleles Dd.
She can explain her reasoning by saying that both pairs of alleles (DD and Dd) has equal chance of being expressed i e, the probability that the mouse has the alleles DD is equal to the probability that it has the alleles Dd. Both pairs each has 0.5 chance of occuring.
Answer:
Explanation:
A Dominant Allele is an Allele that express itself.
DD- this represent a dominant homozygous allele
Dd- represent a dominant heterozygous allele
When an individual with DD is crossed with Dd we will have DD,Dd,DD,Dd
Phenotypic ratio is 2:2
i.e homozgous dominant crosses with heterozygous dominant
which means both DD and Dd have 50% chance of occuring in the genotype and the probabality is the same.
Note that in the phenotype of an individual with homozygous dominant (DD) is the same phenotype with heterozygous dominant(Dd)
