1) What two problems does the transfer of information from DNA to protein need to overcome?
Clues:
a. DNA is made of nucleotides.
b. Protein is made of amino acids.
c. DNA is located exclusively in the nucleus.
d. Protein is synthesized exclusively in the cytoplasm.
Answer:
The two problems that the transfer of information from DNA to protein must overcome are:
How to bring the information from the nuclear DNA to the place of protein synthesis?How to convert this DNA information into amino acids and then into proteins?Explanation:
The genetic information is found in the DNA and depends on a specific sequence of nitrogenous bases. This information is transcribed into the messenger RNA, whose base sequence is organized into triplets and codons, each of which encodes an amino acid, as well as establishing the pattern for starting and stopping the synthesis of a protein.
How to bring the information from the nuclear DNA to the place of protein synthesis?The DNA must be transcribed into messenger RNA (mRNA), a process that occurs in the nucleus of the cell. mRNA leaves the nucleus and travels to the cytoplasm, where amino acid synthesis will take place.
How to convert this DNA information into amino acids and then into proteins?Once in the cytoplasm mRNA binds to ribosomes, structures in charge of translating the sequence of nitrogenous bases RNA to synthesize amino acids. The set of ribosomes and rough endoplasmic reticulum are in charge of the assembly of amino acids to produce peptides and proteins.

What is the difference between aerobic respiration and anerobic respiration?
1.) Aerobic respiration produces ATP, and anaerobic respiration does not.
2.) Anaerobic respiration produces ATP, and aerobic respiration does not.
3.) Anaerobic respiration uses oxygen, and aerobic respiration does not.
4.) Aerobic respiration uses oxygen, and anaerobic respiration does not.
Answer:
The difference is C
Anaerobic respiration uses oxygen, and aerobic respiration does not.
Explanation:
The difference between aerobic respiration and anaerobic respiration is that aerobic respiration uses oxygen, and anaerobic respiration does not. The correct answer is option 4.
Glycolysis is the first step in cellular respiration and can take place with or without oxygen.
Anaerobic respiration is cellular respiration that takes place without oxygen. Aerobic respiration is the type of cellular respiration that takes place when there is oxygen present. Aerobic respiration developed first, then anaerobic.
During aerobic cellular respiration, glucose and oxygen combine to create ATP, which the cell can utilize. As byproducts, carbon dioxide and water are produced.
Without oxygen, organisms must manufacture ATP by anaerobic respiration, which yields just two ATP molecules for every glucose molecule. Anaerobic respiration has the advantage of producing ATP relatively quickly despite producing less of it.

what type of carbon sink does the author propose people use?
Answer: Underground facilities that previously contained fossil fuels
Explanation:
In the attached passage, the author speaks on how natural carbon sinks such as trees and oceans can not be trusted with holding Carbon dioxide indefinitely because oceans are reaching their holding limits and trees are being cut down on a massive scale.
The author suggestion to mitigate this is to convert underground facilities such as oil and gas wells that previously held fossil fuels until they were pumped out. The author claims that the technology to do so is already present and that there are ways this could be made inexpensive.

Answer:
An important term in genetics that was not used by Mendel was the word "gene", a particle of the chromosome responsible for the traits of a living being. The molecule discovered by Oswald Avery - related to genes and inheritance - was DNA, a discovery he made in 1944.
Explanation:
Despite being considered the father of genetics and providing important information about the inheritance of traits, Mendel did not go so far as to use the term "gene," which is where the alleles responsible for those traits reside. The term "gene" was first used by another botanist, Wilhelm Johanssen, who in 1909 proposed the use of the word gene as the name of the particle responsible for inheritance.
In 1944, the Canadian physician Oswald Avery, faced with the mistaken belief that genes were found in proteins, proposed an experiment where he discovered that the molecule responsible for heredity was deoxyribonucleic acid, or DNA.
