The parent cell that enters meiosis is diploid, whereas the four daughter cells that result are haploid.

abruzzese [7]

Answer:

option d

Explanation:

Meiosis stage was formerly called the reduction stage involving two divisions; meiosis I and II. After the first stage of meiosis, the ploidy level of each of the daughter cell changes is in an haploid state, meaning here the DNA content has been reduced by half. In humans (2n = 46), who have 23 pairs of chromosomes, the number of chromosomes is reduced by half at the end of meiosis I (n = 23). This haploid state is still maintained by the meiosis II just undergoing the normal mitosis division.

What prevents the full intake of calcium in milk?

katrin [286]

Phosphorous: Also known as phosphoric acid and phosphate, phosphorous, which is in cola and many processed foods, can interfere with calcium absorption.

Insoluble fiber: This type of fiber, such as the kind in wheat bran, reduces calcium absorption

Foods with high levels of oxalic acid include spinach, collard greens, sweet potatoes, rhubarb, and beans and this will interfere with calcium absorption.

The heart is the major organ in the circulatory system. Which region of the heart supplies oxygenated blood to the aorta?

aev [14]

The LEFT VENTRICLE of the heart supplies oxygenated blood to the aorta.

Aorta is the main artery that supplies oxygenated blood from the heart to other organs and tissues (except lungs, lungs are for gas exchange instead) so that they get enough oxygen and nutrients.

Meanwhile, the heart has 4 chambers, left and right atrium, and left and right ventricles. Atrium are for receiving blood from different vessels, and ventricles are for pumping blood out of the heart.

Since only the left ventricle is connected to the aorta, so, the answer should be left ventricle.

Which extinction factors do you think cause the least extinctions? Why?

vazorg [7]

Answer:

Pollution.

Explanation:

Pollution is the extinction factors that cause the least extinctions because it has less effect on the population of that organisms. Due to pollution, some organisms die and decrease occur in the population while the rest move to another safe place and some lives in that environment produce resistance against that pollution and are able to live in that pollution so pollution is the factor that cause the least extinction.
