Two Changes that happen to your gas exchange system when you exercise regularly
Answer:
Hi hope this helps:
During exercise there's an increase in physical activity and muscle cells respire more
The heart rate increases during exercise.
The rate and depth of breathing increases - this makes sure that more oxygen is absorbed into the blood, and more carbon dioxide is removed from it.

Can someone explain how a cladogram works?
Answer:
it shows ancestral relatedness the traits show where they evolved on the tree with things below that having that trait the hagfish is the outgroup
rabbits and gorillas have fur
Explanation:
Answer:
A cladogram is the diagrammatic result of an analysis, which groups taxa on the basis of synapomorphies alone. There are many other phylogenetic algorithms that treat data somewhat differently, and result in phylogenetic trees that look like cladograms but are not cladograms.

Question 11
Which statement best describes the relationship between inherited traits and genes?
A
An individual's inherited traits are determined by genes, which are located inside a person's chromosomes.
B
An individual's inherited traits are based on a person's environment, and the traits change over time.
С
Inherited traits are determined by a person's health and nutrition.
D
Inherited traits are determined only by a person's maternal parent
Answer: A. Genotype is inherited
Explanation: b,c are about phenotype
D, since the maternal parent is mentioned, one can assume a diploid, sexually reproducing species, in which case both parents’ genes contribute.
Through their genes, parents transmit features or qualities to their offspring, such as eye color and blood type. Thus, option A is correct.
What is relationship between the inherited traits and genes?We can pass on inherited features to the next generation since they are encoded in our DNA.
Examples include eye color, height, skin tone, and hair color. The differences that come from reproduction may be passed down through families, increasing the likelihood that entities will survive.
Dominant and recessive alleles are the two categories. A recessive allele is written with a lowercase letter, and a dominant allele is written with a capital letter.
The progeny will exhibit the dominant trait if a gene pair contains the dominant allele.
Therefore, An individual's inherited traits are determined by genes, which are located inside a person's chromosomes.

The number of chromosomes is DOUBLED after mitosis. True or False, AND explain.
PLEASE HELP IT'S DUE TODAY!!!!
Answer:
False
Explanation:
The number of chromosomes is doubled during mitosis, but each daughter cell (new cell) has the same number as the mother (original cell)
Mitosis is a cell division cycle in which the parent cell divides to produce equivalent daughter cells. It can occur in the body for growth, replacing dead cells etc.
The statement is False.
The sentence can be explained as:
Mitosis is a function of division in cells in which the two exact daughter cells are produced from the parent cell division of the nucleus and cytoplasm.The parent cells undergo the doubling of the hereditary content by the process of central dogma during the synthesis stage. The parent and daughter cell is diploid during this sort of cycle and does not get halved or duplicated at the end of the cycle.Therefore, chromosomes do not get doubled at the end of the division.

The forearm of all of these
animals are considered
homologous structures. Why?
A. They develop from the same embryonic
tissue.
Human
Bird
B. They are the most important sets of
bones.
C. They have no current use.
D. These animals do not share a common
ancestor.
Answer: its A
Explanation:
They have no current use, because they were passed down from a common ancestor, homologous structures are those that are comparable in related organisms, hence option C is correct.
What is homologous structures?The descendants of these structures may or may not carry out the same purpose. Tetrapods' four limbs are an illustration of homologous features. All four limbs are present in birds, bats, mice, and crocodiles.
Bony fish such as sharks do not. Tetrapods evolved four limbs, and their descendants have carried on this trait.
As a result, the presence of four limbs is a homology. The upper arm of both humans and cats consists of just one bone, which we refer to as the humerus, and two forearm bones, the radius on the more medial side and the ulna on the more lateral side.
Therefore, option C is correct.

1. The nucleus is the site of
in protein synthesis
A. transcription
B. translation
The nucleus is the site of transcription in protein synthesis.
What do you mean by Transcription?Transcription may be defined as a process through which a cell makes a copy of RNA (mRNA) from a strand of the DNA.
These messenger RNA carries the genetic information which is essential to make a protein in a cell. The process of transcription occurs in the nucleus of the cell.
While translation is the process by which the sequences of mRNA may transform into proteins. This process occurs in the cytoplasm of the cell.
Therefore, the nucleus is the site of transcription in protein synthesis.

Look again at the enzyme diagram and it’s target molecule. How might a mutation affect the interaction between the enzyme and its target and the function of the enzyme in the organism?
By viewing the enzyme diagram and its target molecule, we can infer that a mutation might affect the interaction between the enzyme and target because it may change the shape of the enzyme and consequently inhibit its function.
What is a genetic mutation?A genetic mutation can be defined as a permanent alteration in the DNA sequence that makes up a gene, which affects the production of a protein and may have a wide range of effects on the function of a cell.
Therefore, with this data, we can see that a genetic mutation may modify the protein and thus affect the reaction.
