Biology

Answer:

Because it has a double division, it's like a double mitosis process

Explanation:

As you can see in the image below, meiosis has a larger process than mitosis, and it results in 4 new cells. Actually, the first part of the process is very similar to mitosis, but the next part is the second division and thats the moment when new cells result just with half chromosomes.

In fact, meiosis is the reproduction process of sexual cells, and these cells need to have just half chromosome, because when a fetus is formed by an ovule and a spermatozoon (both of them just with half chromosomes) the genetic information is gonna be complete and not duplicated.

Trava [24]

Answer:

0.25%

Explanation:

20 people start the new population. So there are 20 genes or 40 alleles for the recessive disorder phenylketonuria. 2 out of 40 alleles are recessive for the condition hence frequency of the allele = 2/40 = 0.05

Frequency of the allele does not change when the population increases so it is in Hardy-Weinberg equilibrium. According to it, if q is the frequency of recessive allele, q² = frequency of the recessive condition

Here, q = 0.05 So,

q² = (0.05)² = 0.0025

In percentage, it is 100 * 0.0025 = 0.25%

Hence, incidence of phenylketonuria in the new population is 0.25%

mafiozo [28]

Patty (age 7) has symptoms that include a skin rash, fever slowed growth, fatigue, and swelling in the joints. She was diagnosed as having juvenile rheumatoid arthritis.

What is juvenile rheumatoid arthritis described as?

Juvenile rheumatoid arthritis is the most common kind of arthritis in children. It is characterized by heat and discomfort and causes the joints to expand. The duration of acute arthritis can range from a few weeks or months to years or even a lifetime. It can also be persistent. IA types include autoimmune and autoinflammatory illnesses. This suggests that the immune system, which is meant to fight off viruses and pathogens, becomes confused and attacks the body's cells and tissues. The doctor can suggest blood testing for C-reactive protein and erythrocyte sedimentation rate. These blood tests evaluate inflammatory markers or markers of inflammation.
