If methods were developed to improve the efficiency and effectiveness of one system, what effect might that improvement have on

Thepotemich [5.8K]

Minor Malfunction: If the Excretory doesn't do it job, waste will begin to pile up in the body, ultimately leading to death.Improvement: If the respiratory cold take in more air, more blood would be transported to the brain. Which will make almost all senses feel sharper and will understand things more clearly.

In a holistic approach to the study of

harina [27]

Answer:

C

Explanation:

A holistic approach to an issue means that there are several interconnected parts to the issue and referring to all these parts is necessary in order to tackle the issue.

Hence, in a holistic approach to the study of environmental science, a student might look at the complete system consisting of individual parts.

The correct option would be C.

Which of the following statements about DNA is FALSE?

Gwar [14]

Answer:

A) The two strands of a DNA molecule are parallel and complementary.

Explanation:

DNA is a polymer of nucleotide and this nucleotide are made up of a deoxyribose sugar molecule, a nitrogenous base, and a phosphate group. In DNA genetic information of the cell is stored in the form of nitrogenous bases.

DNA is double-stranded and both the strands run anti-parallel with each other. This anti-parallel orientation provides the nitrogenous base of one strand to form hydrogen bonds with the nitrogenous base present on the opposite strand.

In DNA adenine base pairs with thymine with two hydrogen bonds and guanine base pairs with cytosine with three hydrogen bonds. So the false statement is A.

N the cross shown here, involving two linked genes, ebony (e) and claret (ca) in drosophila, where crossing over does not occur

jonny [76]

I found the full exercise on the internet and it ends like this:
"These genes are 30 cM apart on the third chromosome. Explain how this ratio arose." Attached is an image of the cross mentioned above.
Crossing over in the female contributed to the possible existing allele combination |e-ca| that did not exist in the parents genotypes. With this new allele combination, the new possibilities are |♀e-ca/♂e-ca+|, |♀e-ca/♂e+-ca|, |♀e+-ca+/♂e-ca+|, and |♀e+-ca+/♂e+-ca|, leading to the respectively phenotypes ebony, claret, wild, wild. These results correspond to the obtained phenotype ratio.
