3. What challenges do older generations face?
Answer:
Health problem. As aging occurs, the more weak and unstable the body gets.
Unporportionate generation distribution. Some older generations are larger than the ones that precede it, thus, making it harder to have the proper resources to take care of older generations.
Technology. It is harder for older generations to be up-to-date on technology. This can make it harder for older generations to function in society properly.

Amphibians, such as frogs, have adapted to have thin, very permeable skin that is well supplied with blood vessels. How does this adaptation most likely help amphibians survive in aquatic environments?
A. It allows them to maintain fairly stable internal temperatures.
B. It allows them to absorb nutrients directly from their environment.
C. It allows them to release chemicals into their environment to attract mates.
D. It allows them to take in oxygen and release carbon dioxide through their skin.
Answer:
to allow easier gas exchange
Explanation:
What term best describe the role of carbon dioxide in the human body
Answer:
Carbon dioxide is essential for internal respiration in a human body. Internal respiration is a process, by which oxygen is transported to body tissues and carbon dioxide is carried away from them. Carbon dioxide is a guardian of the pH of the blood, which is essential for survival.

How many combinations of A, C, G, and U exist? Include an equation
Answer:
64
Explanation:
4 ^ 3 because your first nucleotide can be any of the 4, same with your second, and same with the last nucleotide. 4^3 tells you there are 3 different positions that 4 different bases can be placed.
Hope this helps!
There are 64 possible combinations of nucleotides to form a given amino acid.
The genetic code to add an amino acid is the result of a triplet of nucleotides or codons. In consequence, there are 4^3 possible combinations of nucleotides in a codon.This number (64) gives us the number of different codons that can be found in the genetic code.In conclusion, there are 64 possible combinations of nucleotides to form a given amino acid.

The pedigree below depicts a dominant trait. What is the genotype of individual I-1 (use the letter A for a dominant allele and a for a recessive allele)? How did you come to this conclusion? Using your best grammar, write 3-5 sentences.
A pedigree chart is a diagrammatic representation showing the occurrence and appearance of phenotypes of a particular gene/traits and its ancestors from one generation to the next establishing relationships between individuals in a family.
Using the letter A for a dominant allele and a for a recessive allele, the genotype of individual I-1 is Aa.
In the key pedigree nomenclature, an individual marked with the black ink is affected with the trait (and this trait is dominant - A). Looking at the F1 generation, there are males affected and females as well. For inheritance of the trait, just one copy is enough to become affected. Therefore, the male parent is heterozygous for the trait and the female normal (aa) to enable the production of both affected and non-affected individuals.Learn more about pedigrees: https://brainly.com/question/318443
