Sally and Harry fall in love. They introduce Sally's identical twin, Emily, to Harry's identical twin, Ken. Soon there is a doub

le wedding where Sally marries Harry and Emily marries Ken. Both Sally and Emily get pregnant. They wonder "Will their babies look exactly alike?" Answer their question, and explain your reasoning. (To answer this question, think about the children that could be produced if both pairs of identical twins are heterozygous Aa.)

No their babies won't look alike.

<h3>Explanation:</h3>

Both the couples mentioned here i.e. Sally - Harry and Emily - Ken are both identical twins. So they have similar pairs of genetic setup. This was possible because they developed from same zygote.

But during gametogenesis, crossing over and independent assortment occurs which brings about variation in genetic setup among the offspring. And it's very less probable that same crossing over will occur between the gametes of these couples. So, their offsprings won't look same.

1. Which of the following molecules is broken down in cellular respiration, providing fuel for the cell?
vladimir1956 [14]
1. Cellular respiration is a metabolic pathway that occurs inside the cell. During cellular respiration, glucose molecule is broken down in the presence of oxygen.

2. During cellular respiration, ATP (Adenosine Triphosphate) molecule is also produced that acts as energy currency and directly powers cell work.

3. Amylase is an enzyme that helps in digestion. It catalyzes the hydrolysis of starch into simple sugars. If amylase is present in normal amount it will break down starch into disaccharides. If the amount of disaccharidase amount is less than usual then less disaccharides will be broken down into monosaccharides. Thus the production of monosaccharides will decrease.

4. In the reactions shown above, the end product is largely dependent on the last enzyme. If Enzyme3 is in less amount than usual then there will be greatest reduction in the production of G and H. This is because the formation of product in any reaction is dependent on the substrate concentration and enzyme concentration.

Suppose virus A has a viral genome of 19,000 bp, and 10,000,000,000 viruses are replicated in an infected individual in a single
Kitty [74]

Answer:

1 day.

Explanation:

From the given information:

The rate of mutation induced by RNA polymerase is:

\implies \dfrac{1}{10000}= 0.0001

Since the genome comprise of 19000 bp;

To complete a single replication, the viral cycle induce: = \dfrac{19000}{1000}

= 1.9 \ mutation \\ \\  \simeq 2 \  mutation

However, in a single day; 10,000,000,000 viruses are reported to be replicated.

Hence, if a virus has 2 mutations; Then 10,000,000,000 virus will have:

= \dfrac{10,000,000,000}{2} \\ \\ = \text{5000000000 \ mutations \ in \ a \ half \ day which is half} \\ \\ \text{ the given no of the replicated virus}

SO, to round this up to whole number, it will take 1 day (s) to overcome the therapy.
