A woman, Penelope, has a sister with polycystic kidney disease (ARPKD), which is inherited in an autosomal recessive mode. Penelope does not have the disease, and both of her parents do not have ARPKD. Penelope marries a man from Europe who does not have ARPKD. There is no information about whether this disease runs in his family, but 96% of the population does not have ARPKD (assume the disease is in Hardy-Weinberg equilibrium). What is the probability that they will have a child with ARPKD?
A) 0.25
B) 0.15
C) 0.05
D) 0.04
E) there is not enough information to answer this question

### Answers

Answer:

D) 0.04

Explanation:

Assuming that a is the recessive allele when homozygous that causes the polycystic kidney disease and A is the dominant one:

Since Penelope's sisters has the disease, she must be homozygous recessive (aa). Her parents must both be Aa (otherwise her sister wouldn't have inherit the disease).  So, the probability of Penelope of being heterozygous (Aa) is 0.5.

On the other hand, the probability of having the disease in the population is 0.04 (1 minus the probability of not having the disease which is 0.96). This, according the Hardy–Weinberg principle, in the population would represent  the genotype frequency . So, the allele a would have a frequency = = 0.2. Since the gene has only two alleles, all alleles must be either A or a , therefore p + q = 1. So, the A population's frequency is p = 1 - q = 1 - 0.2 = 0.8.

The European man's probability of being Aa (doesn't have the disease but can carry the disease allele) is 2pq = 2 x 0.8 x 0.2 = 0.32.

The probability of Penelope and the European man of having an ill kid (assuming they both are Aa) is 0.25.

Finally, given the Penelope's probability of being Aa (0.5), the European man's 's probability of being Aa (0.32) and the probability of having a kid homozygous recessive aa (0.25) = 0.5 x 0.32 x 0.25 = 0.4 is the probability that they will have a child with ARPKD.

(GIVING BRAINLIEST AND EXTRA POINTS!!)Edwin wrote the following notes about static electricity. When an uncharged object is placed close to a charged object, the objects can attract or repel each other. When two electrically charged objects are placed next to one another, the objects can also attract or repel. What statement will correct the error in Edwin's notes?

A) An electrically charged object needs to touch an uncharged object before they attract or repel.

B) When an electrically charged object comes close to an uncharged object, it will attract it.

C) If an electrically charged object is near an uncharged object, it will repel it.

D) When two electrically charged objects are placed close together, they only attract.

### Answers

The statement that will correct the error in Edwin's notes is as follows:

• An electrically charged object needs to touch an uncharged object before they attract or repel.

Thus, the correct option is A.

### How do electrically charged objects produce attraction?

The electrically charged objects produce attraction of oppositely charged objects. For example, if a positively charged object and a negatively charged object bring close to each other, they interact with one another. Their forces act in the same direction. i.e. from the positive to the negative charge.

There is an interaction between two oppositely charged objects required in order to furnish attraction, while there is an interaction between two identical charged objects required in order to furnish repulsion.

Whether it is attraction or repulsion, it must be required that an electrically charged object needs to touch an uncharged object.

Therefore, the correct option for this question is A.

### Answers

Answer:

Epigenetic mark

Explanation:

A methyl group attached to the nitrogenous base of one amino acid on the DNA is known to have effects on the expression and transcripcion of the genes, and this is also called epigenetic modifications. Therefore, an methyl group attached to the DNA is responsible for epigenetic modifications and so is an epigenetic mark.

Answer:

Ahmed and Fatima, two teenage siblings, are fighting over the evening newspaper. Knowing Ahmed only wants the sports section and Fatima only wants the latest stock quotations, their mother takes the paper and gives each the section containing their news of interest. In the context of mediation, the mother arrived at a(n) integrative agreement.

Explanation:

In business studies, an integrative agreement can be described as a situation in which all the parties benefit from an action and are in win-win situation. An integrative agreement tends to find beneficial options for both the parties at dispute so that a mutual agreement can occur between them.

In the following scenario, Ahmed and Fatima's mother provided a solution which benefited both of them. Hence, it is an example of an integrative agreement.
