Can a human male be a carrier of red-green color blindness?
miskamm [114]

Answer:

The answer is no Human male can not be carrier for the red green color blindness.

Explanation:

Red green color blindness is a sex linked disorder that is recessive in nature. If an individual male have one copy of X gene with recessive allele of the trait he will be color blind because male have only one copy of X chromosomes and one copy of Y chromosome. So, the recessive X chromosome will express itself in absence of dominant X chromosome.

For being a carrier one should be heterozygous For this gene and its not possible in males as they have only one copy of X chromosome.

Thus, the correct answer is No.

A group of single-cell organisms collected from the ocean was brought into the lab for examination. The lab assistant was concer
jolli1 [7]

The correct answer is C. She added water that was hypotonic to the culture of organisms, and they ruptured.

Explanation:

In biology, a hypotonic solution is a substance with less concentration than the inner concentration in cells, this is the opposite of a hypertonic solution that has a higher concentration. Additionally, if cells are in hypotonic solution water or liquid will begin to get into them and this would make cells burst and finally explode and die due to the pressure in them.

This occurred in the case presented as it is likely the organisms collected from the ocean had a high concentration and therefore hen they were exposed to clean water in which concentration was lower, water entered into the cells and made them explode, which explains the only remains of them were bit and pieces.

Typical chemical formula for beta d galactose is _________________________with a double bond to oxyygen at the __carbon in the f
lawyer [7]

Typical chemical formula for beta d galactose is C_{6} H_{12} O_{6} with a double bond to oxygen at the <u>1st</u> carbon in the fisher projection.

A stereo formula can be represented in two dimensions using Fischer projection and Fischer projection formula despite losing the stereochemical information, including absolute configuration, near chiral centers.

Galactose lies in the D- configuration if the hydroxyl group (-OH) in carbon 5 appears on the right side with the Fischer projection. Galactose becomes L-sugar whenever the hydroxyl group of carbon 5 occurs on the left side with the Fischer projection.
