Is DNA replication always a foolproof process? Explain your answer.
Answers
Answer: No. Although many proteins check the DNA for damage or errors, damaged regions can still be replicated. This may result in gene alterations and serious complications for the organism.
Explanation:
No, replication is not always a foolproof process although many proteins look for DNA damage or mistakes, damaged areas can still replicate. This can lead to gene rearrangements and serious problems in the body.
Some mutations are caused by mistakes in DNA replication. DNA replication isn’t always 100% complete. Sometimes, an incorrect base is inserted into the new DNA strand. This incorrect base can become permanent.
Breaks in DNA are caused by DNA replication errors, particularly those in regions that are difficult to replicate, known as fragile sites.
Breaks in DNA can cause cancer, mainly because they increase the risk of chromosome fragments rearranging themselves and activating genes that cause uncontrolled cell division.

Answer:
1. Fluid or water balance
2. Electrolytes
3. Thirst mechanism.
4. Osmosis
5. Dehydration
6. Diuretics
7. Interstitial fluid
8. Hyponatremia
Explanation:
1. Fluid or water balance is achieved when there is an equal concentration of water and electrolytes inside and outside the body's cells. The thirst mechanism of the body serves to maintain fluid balance of the body state by ensuring that enough fluid is consumed to allow for an equal concentration of electrolytes between the intracellular and extracellular fluid compartments.
2. Charged ions such as sodium, potassium, and chloride are called electrolytes. They are the molecules which help the body to maintain fluid balance when they are pumped in or out of the cell.
3. The feeling of dry mouth experienced during dehydration is part of the body's thirst mechanism.
4. The process by which water moves in and out of cells from an area of lower concentration of solutes to an area of higher concentration of solutes is called osmosis.
5. If you are not consuming enough water, or if you are excreting too much water from your body, dehydration can occur.
6. Diuretics are substances that cause the body to lose water via urine.
7. The liquid that is between cells is called interstitial fluid.
8. Hyponatremia (low sodium concentration) occurs when the extracellular concentration of sodium is too low. It can occur when too much water is consumed over a short period of time, or it can occur due to sodium loss from the body due to kidney diseases.

Question 1. What change led to an increase in the number of light-colored moths within the population?
1. More mutations
2. Decreased pollution
3. More dark colored trees
4. Fewer humans
Question 2. Claim: Individuals in a population have genetic variations that can be passed on to their offspring. Refer back to the rabbits in the desert from the natural selection activity we did in class. How could an organism's traits influence the survival rate of the population?
Answers
Answer: 1. 1. More mutations. 2. According to Charles Darwin's theory of evolution by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation.
Explanation:
Many closely related species of ducks have different courtship dances that are performed to solidify a pair-bond. If you were to cross individuals from each of these species what would you expect to see in the hybrid offspring if behaviors related to pair-bond formation were completely due to genetics?
Answers
Answer:
I would expect to see a new phenotype in which the new duck hybrid species would express a new mixed courtship dance with the behaviors of both parentals.
Explanation:
The cross between both parentals, each from different species, might produce a new phenotype that exhibits both parental dances. The new dance might be considered a hybrid of the parental dances.
Genetically speaking, we can think that there is a gene codifying for the courtship behavior in one species and another gene expressing a different courtship behavior in the other species. This cross´ product would be a hybrid species that exhibits a part of both parentals´ behaviors.

Explanation:
Opposites for REGULAR mDNA base pairings are T= A and G = C, however, since it is mRNA, your base pairings change a little. G is still to C BUT Thymine (T) becomes Uracil (U) so A= U instead of A= T. So big difference between mRNA and mDNA is that Thymine changes to Uracil and vice versa depending on how the code is being translated.
