Anaphase 2 is the correct answer.
SVETLANKA909090 [29]3 years ago
5 0

Answer:

This would occur in Anaphase II.

Explanation:

Anaphase II, in meiosis, is a process very similar to anaphase of mitosis, where the separation of sister chromatids from duplicated chromosomes occurs. That is, it is at this stage that the chromosomes are separated.

If the gamete that participates in the fertilization has received one more or less chromosome from an error of this separation, the embryo formed may suffer from some disease, as is the case of Down Syndrome. In this disease, the carrier has 3 chromosomes number 21 instead of just 2, one from the father and one from the mother. The third chromosome is the result of chromosomal non-separation of pair number 21 when gametes are produced.

Non-separation can also occur on sex chromosomes. A girl who receives an extra X chromosome will have the 44A, XXX (triple X syndrome) karyotype, which will result in mental problems, for example. A boy may have two Y sex chromosomes, for example, and have the 44A karyotype, XYY (double Y).

Trace minerals are needed in much smaller amounts than major minerals, but they are just as essential for good health. They are
kow [346]

Answer:

1. Heme iron is found in animal foods like meat and poultry, whereas the nonheme iron form is found in plant foods like grains and vegetables.

2. The metal and trace mineral copper is part of several enzymes and proteins.

3. Adequate zinc is important for maintaining a healthy immune system and may aid in wound healing.

4. Selenium acts as an antioxidant and aids in thyroid function.

5. Fluoride is not considered essential, but it is very important for maintaining strong, healthy teeth.

6. The deficiency disease goiter was much more common before iodine was added to salt in the United States.  

7. Manganese acts as a cofactor for a variety of enzymes and also plays a role in synthesis of bone.

Explanation:

  • Iron: The major difference between the iron provided by animals Heme Iron) and plants (Nonheme iron) is that the heme iron is better absorbed by the organism. There are several mechanisms in the intestine that improve the heme iron absorption that is used for producing red globules for the organism. Carnic products such as red meat, fish, and poultry are rich in heme iron. Vegetables contain nonheme iron, which is harder to assimilate by the organism and thus its absorption is lower.
  • Copper: Is an essential element for life that intervenes in the electronic transport chain, being part of the IV complex. It is also part of the enzyme that catalyzes the decomposition of the superoxide ion, toxic for living organisms. Copper is an element of the hemocyanin which is a protein present in some invertebrates, with a function similar to hemoglobin.
  • Zinc: This metal has many uses in industry. In health, it is used in dietetic supplements, to maintain its correct levels. It is also useful in wound healing, in reducing duration and severity of colds, and has antimicrobial properties that help to relieve gastroenteritis symptoms. It is added in solar protectors, in toothpaste for good breath, and in the shampoo to deal with dandruff problems.
  • Selenium: It is an antioxidant component of some enzymes that act in the elimination of substances with reactive oxygen. Besides this element is important in the regulation of the thyroid function.
  • Fluoride: Although it lacks if metabolic activity in mammals and superior plants, some plants and marine sponges can synthesize a fluor compound as a poison for protection. Fluoride is used in many kinds of toothpaste because it interacts with calcium to create a harder and more stable fluorapatite matrix that protects the teeth.
  • Iodine: Is an essential element that intervenes in numerous functions in the organism. The only entranceway of the element is by ingesting it with a recommended diet. Iodine lack might cause several problems in health such as thyroid problems or goiter.
  • Manganese: This metal is an essential element that exists naturally in the ground and water. For animals, the manganese is an essential component of enzymes that are used in carbohydrates, fat, and protein metabolism. Manganese is a cofactor for numerous enzyme activities. It is also important in bony tissue development and reproduction.

Which is not a source of emerging diseases?
Illusion [34]

Answer:

The term "disease" refers to conditions that impair normal tissue function. For example, cystic fibrosis, atherosclerosis, and measles are all considered diseases. However, there are fundamentally different causes for each of these diseases. Cystic fibrosis (CF) is due to a specific genotype that results in impaired transport of chloride ions across cell membranes, leading to the production of abnormally thick mucus. Thus, CF is most accurately called a genetic or metabolic disease. Atherosclerosis, which can lead to heart attacks and strokes, may be considered a disease of aging, because it typically becomes a problem later in life after plaques of cholesterol have built up and partially blocked arteries. In contrast, measles is an infectious disease because it occurs when an individual contracts an outside agent, the measles virus. An infectious disease is a disease that is caused by the invasion of a host by agents whose activities harm the host's tissues (that is, they cause disease) and can be transmitted to other individuals (that is, they are infectious).
