In meiosis I, homologous chromosomes separate, while in meiosis II, sister chromatids separate. Meiosis II produces 4 haploid daughter cells, whereas meiosis I produces 2 diploid daughter cells. Genetic recombination (crossing over) only occurs in meiosis I.
Answer:
DNA and RNA are composed of nucleotides that are linked to one another in a chain by chemical bonds, called ester bonds, between the sugar base of one nucleotide and the phosphate group of the adjacent nucleotide. The sugar is the 3' end, and the phosphate is the 5' end of each nucleiotide.
Answer:
There is a low probability that a future pregnancy would exhibit similar phenotypes since it probably was a germinative line mutation that affected that egg.
Explanation:
The malformations of the unborn child, probably are due to a mutation in the germ cell of any or both parents. Germline mutations are detectable changes in a sperm or egg that we can see when the fetus is growing, as malformations since the original germ cell that was mutated divided itself to give more mutated cells for all the different parts of the fetus.
Answer:
The correct answer is C.
Explanation:
The respiratory center is divided into 3 main groups, the dorsal respiratory group and the ventral respiratory group, both located in the <u>medulla</u>, and the pontine respiratory group, located in the <u>pons</u>. This last one also divides into two areas: <em>the pneumotaxic and the apneustic center.</em>
During quiet, restful breathing, the dorsal group stimulates the diaphragm and the intercostal muscles for inspiration. Expiration then occurs depending on the elastic recoil of the lungs. When forced expiration is required, the ventral group activates.
Deep water jogging is an alternative form of jogging recommended to patients who are injured and have chronic back pain.
Deep water jogging:
It is an exercise of slow running in the swimming pool, doing this helps in relieving the acute pain as water creates resistance on the by which makes the movement more difficult. This results in stretching of the muscles and more rapid blood flow in the body. This jogging provides benefits the same as jogging or running is done on the ground.
The person recovers from the injury very fast, athletes do this jogging to recover fast from the injury. Overweight people face a high risk of injury on the ground. So, to reduce the risk of getting injured and exercise, deep water jogging is also recommended for overweight people.
