Which pedigree symbol is used to represent a female carrier of a recessive X-linked trait? An empty circle. A half-filled circle. An empty square. A filled square.

Answers

Answer 1
Answer:

Answer:

A half filled circle

Explanation:

In pedigrees, females are always denoted with a circle, and males with a square. Affected individuals usually have coloured or filled symbols, whereas unaffected individuals have an empty symbol.

In the case of carriers, this is often denoted as a half filled symbol. I.e. the shape is filled on one side and not the other, split down the middle). Sometimes a carrier of an X linked condition is denoted as a half filled, but instead of left vs right, the circle is filled with a smaller circle in the middle.

What do animals do with the carbon dioxide produced in their cells during cellular respiration?

Answers

What animals do is that they eat that plant and they get to energy they need from it because since the equation in words for cellular respiration is 
sugar+oxygen------------> carbon dioxide+ sugar+energy
                          energy
so that means during cellular respiration energy is being formed into food and thats what animals eat.

An organism's genomic dna is analyzed and found to contain 22% thymine. what percentage of that organism's dna is guanine?

Answers

In an organism's genomic data, 100 percent is made up of adenine, cytosine, guanine and thymine. Adenine and thymine are complementary pairs in a DNA so they should have the same concentration in the DNA. This would also be the case for Cytosine and Guanine. We are given 22 percent of thymine so we also have 22% of adenine. This would leave us with only 100-22 = 78 percent for both guanine and cytosine. And since they are present in equal amounts, we simply divide the remaining percentage by two to determine the amount of each. Therefore, there would be 78 / 2 = 39 percent of guanine present in that certain DNA.
