Answer:

mitochondria DNA (mtDNA) has maternal inheritance

chloroplast DNA (cpDNA) has paternal inheritance

Explanation:

DNA is deoxyribonucleic acid is the molecule responsible for encoding the genetics instructions used in the development and functioning of all known leaving organism.

in humans mitochondria DNA (mtDNA) has maternal inheritance and

Which pathway is affected by an inherited mutation in the atm gene?
Katena32 [7]

The question is incomplete as it does not have the options which are:

photoreactivation

reactivation repair pathway

nucleotide excision repair pathway

UV repair pathway

p53 repair pathway

Answer:

p53 repair pathway

Explanation:

ATM gene or ataxia telangiectasia-mutated is a gene which codes for the protein kinase involved in the DNA double-stranded break.

The DNA double-stranded break is repaired easily as the protein kinase is recruited to the site of the break where it allows the DNA repair machinery to repair the DNA.

The gene also controls the cell growth therefore this gene is important to study cancer.  Since the p53 protein is a suppressor protein which if mutated is repaired by the ATM gene and if the gene becomes mutated then the p53 repair pathway is affected.

Thus, p53 repair pathway is the correct answer.

Organisms can adapt to their environment within one generation
bezimeni [28]

Answer:

Organisms can adapt to their environment within one generation if they are selected naturally by the nature.

Explanation:

Organisms can survived which can withstand or tolerate the harsh climate of the environment while some organisms removed from that environment due to low survival ability in that harsh climate. This selection is done by nature in which well suited animals and plants can survive in that environment due to certain adaptations. Those organisms can adapt to their environment within one generation due to survival ability and high fitness.

For example, in deserts, bears did not survive because it requires cold climate so only reptiles such as snakes and lizards can survive in this environment.
