Chemoreceptors in the circulatory system detect changes in circulating pCO2. If CO2 concentrations get too high, the rate of ven
Levart [38]

Answer: The more active cells produce more carbon dioxide.

Explanation:

When the cells are constantly working the amount of oxygen consumed and more amount of carbon dioxide is released by the cells.

Chemo receptors in the circulatory system increases the ventilation so that more carbon dioxide can go out of the cell and more oxygen can get inside the cell.

This is because the more active cells more carbon dioxide and there is a sudden increase in the concentration of carbon dioxide which need to be corrected by the help of ventilation.

which evolutionary process determines that individuals of a species best adapted to the environment survive and reproduce
FinnZ [79.3K]

Natural selection is the process through which species adapt to their environments

natural selection is the method through which populations of dwelling organisms and species adapt and exchange. individuals in a population are obviously variable, that means that they will be all unique in a few methods. this variation approach that some humans have trends higher suited to the environment than others. people with adaptive tendencies—traits that supply them a few advantage—are more likely to live to tell the tale and reproduce. those humans then pass the adaptive developments directly to their offspring. over the years, the ones powerful trends come to be more not unusual within the populace. through this machine of natural selection, favorable trends are transmitted through generations.
natural selection can cause speciation, in which one species offers rise to a brand new and rather precise species. it is one of the processes that drives evolution and permits to provide an cause of the sort of existence inside the world
Darwin selected the decision natural choice to contrast with “artificia  selection,” or selective breeding that is controlled via human beings..

(a) Describe the process by which cells produce the FGF5 pre-mRNA , and include the location
Svetlanka [38]

Answer:

Explanation:

mRNA (messanger ribonucleic acid) is produced through the process called transcription in the nucleus. Transcription make ribonucleic acid from deoxyribonucleic acid. The enzyme RNA polymerase creates an RNA molecule that is complementary to the template DNA coping all the information on the DNA into the mRNA formed and 3' to 5' cap are added to stabilize the RNA after which this mRNA then moves from the nucleus where it was produced to the ribosome in the cytoplasm for translation of the information that is coded in the bases.

FGF5 is a gene that is encoded in the DNA.

How many amino acids could be specified if codons consisted of two nucleotides instead of three? What problem would this present
Greeley [361]

Answer:

This could result in a mutation.

Explanation:

A change in the DNA can affect the work of cells because it can cause a mutation; it can be a good mutation or bad. The three main mutations that occur are Insertion, Deletion and Substitution. Insertion is when DNA base(s) are added in, Deletion is when DNA base(s) are removed. Lastly, Substitution is when DNA base(s) are switched on. All of these mutations can have effects. These effects are Silent effect, Missence, and Nonsense. Silent effect is a mutation that does not change the sequence of amino acids in a protein. Missence is a mutation that causes the sequence of amino acids to change. This can cause incorrect protein folding and protein malfunction. Nonsense is a mutation that causes an early stop codon. This effect leads to a protein that is too small. Also a Frameshift can occur. Framshift is when the reading of a frameshift is moved over by one or more bases such that every subsequent amino acid changes. An example of a frameshift is THE CAT ATE THE RAT. If you insert an A at the Beginning this happens ATH ECA TAT ETH ERA T. IN Conclusion there are two Mutations that also play a role in this Point Mutation and Chromosomal Mutaion. Point Mutation is when a single DNA base is either substituted, inserted or deleted from the sequence. Chromocomal Mutation is when large pieces of a chromosome or an entire chromosome is either substituted, inserted or deleted.
