How many molecules of carbon dioxide is produced from cellular respiration?
Answer:
six
Explanation:
Since two acetyl-CoA molecules enter the cycle, and each has two carbon atoms, four carbon dioxide molecules will form. Add these four molecules to the two carbon dioxide molecules formed in the conversion of pyruvic acid to acetyl-CoA, and the total is six carbon dioxide molecules.

What role does reproduction play in both natural and artificial
selection?
Answer:
It allow organisms to pass down their traits to the next generation.
Explanation:
Reproduction can be defined as a biological process which typically involves living organisms producing an offspring.
Basically, there are two (2) methods of reproduction and these are;
I. Sexual reproduction: it involves the combination of the genome (gamete) of a male and female living organism during fertilization.
II. Asexual reproduction: it involves the cloning of a living organism to produce an offspring because there is only a single parent.
Natural selection can be defined as a biological process in which species of living organisms having certain traits that enable them to adapt to environmental factors such as predators, competition for food, climate change, sex mates, etc., tend to survive and reproduce, as well as passing on their genes to subsequent generations.
Simply stated, natural selection entails the survival of the fittest.
Artificial selection is also known as selective breeding and it is a process that involves humans (breeders) selecting the animal or plant with desirable traits in order to reproduce favorable offspring having phenotypic traits.
Hence, the role which reproduction play in both natural and artificial selection is that it allow organisms to pass down their traits to the next generation.

DNA _____.
is a long, single chain of nucleotides
cannot determine behavior traits
contains coded information for the creation of proteins
is enclosed by a nuclear membrane in prokaryotes
Answer:
Answer:
The correct answer would be "contains coded information for the creation of proteins".
DNA or deoxyribonucleic acid is a polymer of nucleotides.
It is the genetic material in most of the living cells present on earth. That is, it controls all the characters and traits of the living organisms.
In prokaryotes, it keeps floating in the cytoplasm whereas it is confined in the well-defined nucleus in eukaryotic cells.
The nucleotide sequence of the DNA is used as the code for the synthesis of the proteins.
It is first transcribed into the nucleotide sequence of mRNA which is further decoded into the amino acid sequence of the proteins.

If a population pyramid has a very broad base then what does that tell you about the population it represents?
Answer:
A population pyramid is defined as a graphical representation that shows distribution of both genders male and female in all age groups.
The base of a population pyramid represents the birth rate, so a very broad base represents the higher population of younger age children and higher birth rate.
Hence, the wide base shows higher population of younger age children and higher birth rate.
What molecule is removed during dehydration synthesis? *
a. Water
b. Carbon dioxide
c. Sugar
d. Carbon
During dehydration synthesis, water molecule gets removed. The correct option is a.
What is dehydration?A dehydration reaction in chemistry is a chemical process in which the reacting molecule or ion loses water. The opposite of a hydration reaction, dehydration reactions are frequent processes.
"Chemical processes known as dehydration reactions are those in which a water molecule is removed from the reactant molecule. Dehydration synthesis is the process of combining two compounds while removing water molecules.
These kinds of reactions can assemble and disassemble nucleic acids, proteins, and carbohydrates, however the monomers in each case vary.
Many polymers are made by dehydration processes as well. Another illustration is the transformation of alcohols into ethers.
Thus, the correct option is a.

Scientific theories can change when new evidence is discovered and is supported and accepted widely. Which statement can possibly create a change in the cell theory?
a. A scientist discovers a new living organism with different cells.
b. A scientist discovers a new living organism with cells but no tissues.
c. A scientist discovers a new living organism that has no cells.
d. A scientist discovers a new living organism that has cells that work separately.
Answer:
c. A scientist discovers a new living organism that has no cells.
Explanation:
The cell theory is a widely accepted and globally recognized theory of living things. It was proposed in the 1830's by the collective effort of three scientists namely: Mathias Schleiden, Theodor Schwann and Rudolph Virchow. The cell theory is made up of three components as follows:
- All living things are made up of one or more cells.
- The cell is the basic and fundamental unit of life.
- All living cells comes from pre-existing cells.
According to this question, a new evidence that can possibly create a change in the cell theory is if a SCIENTIST DISCOVERS A NEW LIVING ORGANISM THAT HAS NO CELLS because all living organisms have been said to be made up of cells in the cell theory.

HIV is a retrovirus whose sequence is RNA DNA → RNA protein which it uses as part of its reproductive cycle. So, the correct option is A.
What is HIV?HIV stands for Human Immunodeficiency Virus which is defined as a virus that attacks the body's immune system. If HIV is not treated, it can lead to AIDS which stands for acquired immunodeficiency syndrome. There is currently no effective cure, while once people have HIV, it remains with it for life.
HIV can spread through sexual contact, illicit injection drug use or sharing needles, contact with infected blood, or from mother to child during pregnancy, childbirth or breastfeeding. HIV is a retrovirus whose sequence is RNA DNA → RNA protein which it uses as part of its reproductive cycle.
So, the correct option is A.
