-Dominant- [34]3 years ago
6 0

Answer:

Crystal Size and Rock Texture

Explanation:

Extrusive rocks are also known as volcanic rocks. Igneous rocks are classified according to their texture and mineral or chemical content. The texture of the rock is determined by the rate of cooling. The slower the rock cools, the larger the crystals form.

A very common type of red–green colorblindness in humans is caused by a mutation in a gene located on the X chromosome. Knowing
Harrizon [31]

Answer:

50%

Explanation:

According to the given information, the allele for the red-green colorblindness is inherited in an X linked recessive manner. Let's assume that the allele X^c is responsible for red-green colorblindness. The woman is normal but had a colorblind father (X^cY). Fathers give their X chromosomes to the daughters while their Y chromosome is transmitted to their sons. The sons get their X chromosomes from the mother.

The colorblind father has transmitted the X-linked allele for the red-green colorblindness to his daughter. Therefore, the genotype of the woman is X^cX. The woman would produce two types of eggs: 50 % with X^C and 50% with X. Therefore, 50% of sons of this woman would get X linked allele for the red-green colorblindness and would be affected by the disorder while the rest 50% of her sons will be normal.

What is mixed-acid fermentation? how is methyl red used to determine if a microbe has undergone mixed-acid fermentation?
Vika [28.1K]

Mixed Acid Fermentation is a biological process by which a six carbon sugar is converted into complex mixture of acids. It is an example of anaerobic fermentation reaction which is commonly seen in bacteria.

The fermentation produces lactate, acetate, succinate, formate, ethanol, H_{2} and CO_{2} and their formation depends upon the presence of certain key enzymes in the bacterium.

The Methyl Red test is used in detecting occurring of mixed acid fermentation pathway when glucose is provided to microbes by using ph indicator. If the fermentation pathway has taken place, the mixture of acids will make the solution very acidic and causes red color change. The Methyl Red test belongs to the group called as IMViC tests.
