4. Explain why nuclear radiation can be used to preserve food.
Answer:
The radiation destroys food-borne bacteria. Radiation is measured in units called rads. The FDA allows exposure of up to 100,000 rads for already approved foods.

Typical gram-negative bacteria are more impervious to the action of antimicrobial chemicals than are gram-positives because gram-negatives have a(n)
As gram-negative bacteria have an extra layer of cell wall therefore it is less sensitive towards antimicrobial chemicals than gram-positive bacteria.
Why gram-positives are less impervious to the action of antimicrobial chemicals?Gram-positive bacterial cell wall is made up of only the peptidoglycan layer and it does not have an extra barrier that protects it from some antimicrobial chemicals.
Gram-negative bacteria have two layers of cell wall peptidoglycan layer and a lipopolysaccharide layer.
Thus, gram-negative bacteria have an extra layer of cell wall.

Why must cytosine bind to guanine, while thymine bonds to adenine?
a
These are Chargaff's rules.
b
Like bonds with like.
c
Two-ring molecules (adenine and guanine) must bind with one-ring molecules (thymine and guanine) to keep the distance between DNA chains consistent.
d
This will not happen, as it violates Chargaff's rules.
These are Chargaff's rules that is why cytosine bind to guanine, while thymine bonds to adenine. Thus, the correct option is A.
What is Chargaff's rule?According to the rule, in DNA there is always equality in quantity between the bases A and T and between the bases G and C. (A is adenine, T is thymine, G is guanine, and C is cytosine).
According to Chargaff's rule, Concentration of adenine = concentration of thymine. therefore if [A]=40% then the [T] will also be 40%.

2. (b) Why is it important to maintain genetic diversity in populations?
Genetic diversity encourages the health of a species and provides material resources such as plants. The loss of genetic diversity leads to reduced options for mates which means even more loss of a species and the species becomes more susceptible to disease. These are very few results that occur with the loss of genetic diversity.
A biologist sequences the DNA of two different organisms and identifies these two sequences:
Sequence 1: GTACCACATCGAAGGGTC
Sequence 2: GTACGACACCGAAAGTTC
What conclusion can the biologist draw about the two organisms based on the DNA fingerprinting?
A.They are closely related but different species.
B.They are the same species.
C. One organism evolved from the other.
D. They are not related at all.
The two DNA sequences of organisms represent that they are closely related but different species.
What do you mean by Species?Species may be characterized as a group of organisms that can reproduce naturally with one another and produce fertile offspring.
DNA fingerprinting is a technology that reveals the similarity between the DNA sequences of two or more organisms of the same or different species.
Both the sequence are very similar to one another, only a few bases are altered which signifies that they are closely related but belongs to different species.
Therefore, the two DNA sequences of organisms represent that they are closely related but different species.

What is the net result of one glucose molecule going through the krebs cycle.
Answer:
Recall that glycolysis, stage I of cellular respiration, produces two molecules of pyruvate. These molecules enter the matrix of a mitochondrion, where they start the Krebs cycle.
Two molecules of pyruvate are produced during the first stage of cellular respiration, glycolysis. These substances enter a mitochondrion's matrix, where they initiate the Krebs cycle.
Thus, A little quantity of ATP (adenosine triphosphate) is produced by the Krebs cycle through substrate-level phosphorylation. Two ATP molecules are directly created in the Krebs cycle for every glucose molecule.
Electron transport chain (ETC): The Krebs cycle also generates high-energy electron carriers called NADH (nicotinamide adenine dinucleotide) and (flavin adenine dinucleotide), which transport the electrons to the ETC for additional ATP generation.
Carbon dioxide is generated as a waste product during the Krebs cycle's breakdown of glucose. Six CO2 molecules are produced overall for every molecule of glucose.
Thus, Two molecules of pyruvate are produced during the first stage of cellular respiration, glycolysis. These substances enter a mitochondrion's matrix, where they initiate the Krebs cycle.

A crocodile that has birds in its mouth represents a type of parasitism, whereas scavenger behaviors include:
bearshyenas piranhasWhat is parasitism?Parasitism is a class of symbiotic relationships in which one species is benefited from such interaction and the other species is harmed.
In this case, when the crocodile needs to clean its tooths, it opens its mouth to allow the arrival of birds.
Moreover, scavengers are organisms that eat dead biomass (e.g. dead animals or rotting plants).
In conclusion, although the movie is NOT found here, a crocodile that has birds in its mouth represents a type of parasitism, whereas animals having scavenger behaviors include bears, hyenas and piranhas.
