Answer:

Ecosystem

Explanation:

The ecosystem includes a total of the abiotic and biotic components of a region. These components interact with each other and make the ecosystem self-sufficient in terms of energy and nutrients. Climatic conditions, physical factors, soil type, and its feature together make the non-living or abiotic part of an ecosystem. They interact among themselves and with the living components by nutrient cycling. All the species of living beings together make the biotic components of an ecosystem. They interact with each other by food chains and food webs.

Oceans are an example of the aquatic ecosystem while deserts are terrestrial ecosystems.

Estrogens from the vesicular follicle trigger an LH surge from the anterior pituitary. This is an example of: Estrogens from the
brilliants [131]

Answer:

The correct answer is: positive feedback.

Explanation:

Positive and negative feedback are terms that are used to define the way a system is regulated by its products. For example, when the production of a certain substance <u>inhibits</u> its producer that is called <u>negative feedback</u>. On the other hand, when a substance <u>stimulates</u> its producer to keep secreting said substance, this is called <u>positive feedback</u>.

Estrogen is a hormone of great importance in the female reproductive cycle and is secreted by the follicle cells in response to the presence of FSH (follicle-stimulating hormone), released by the anterior pituitary when stimulated by the GnRH (gonadotropin-releasing hormone).

Estrogen appears at the beginning of the cycle to stimulate the development of the ovarian follicles, and the hormone levels continue to rise as the cycle advances. Up until the 14th day of the cycle, estrogen has a negative feedback on GnRH and FSH, but then it makes an abrupt change to now exert positive feedback on GnRH to stimulate the release of LH (luteinizing hormone), which will be responsible for ovulation.

Hemophilia is a disease that causes uncontrollable bleeding. If a father has it, all of his daughters will be carriers of the di
Ipatiy [6.2K]

Answer:

<em>Yes, the following description is true.</em>

Explanation:

Hemophilia is a sex-linked recessive disorder. This means that only one allele recessive allele for the trait in males will cause the disease to occur in males. However, for females, there should be two recessive alleles present for the gene for the trait to occur. A female carrying one recessive allele for the trait will be a carrier.

If a father is hemophiliac, this will mean that all the daughters will be carriers for the disease as they will have one of the allele for the trait from the father. On the other hand, about half of the sons will have the disease if they get the recessive allele from the father for the trait.

What is the most important reason for studying soil structure​
ziro4ka [17]

"A good soil structure is important to allow air and water into the soil which are vital for healthy plant growth. It will improve drainage and reduce soil erosion caused by excess surface run-off."

Describe the changes that take place during the menstrual cycle from Day 5-13 to the following:
erastovalidia [21]

Answer:

Between days 5 and 13 of a woman's menstrual cycle, an unfertilized egg in ovary prepares its development and maturation within the follicle, while the lining of the uterus -the endometrium- progressively enlarges.

Explanation:

Under normal conditions, a woman's menstrual cycle lasts 28 to 30 days, during which time both hormonal and physiological changes occur as part of the reproductive process.

Menstruation occurs as a result of the shedding of the endometrium, which had previously developed to facilitate the implantation of a possible pregnancy. This phase usually lasts five days and is characterized by genital bleeding.

From the fifth to the 13th day, a woman's reproductive system undergoes changes in preparation for possible fertilization and pregnancy:

  • <em>The unfertilized egg</em><em> is found inside the ovarian follicle, maturing before its imminent release, under the influence of follicle-stimulating hormone (FSH). The maturation of a few follicles occurs simultaneously, but only one will reach the necessary maturity to allow the release of the egg. </em>
  • <em>The lining of the uterus</em><em>, called the endometrium, receives signals from the hormone estradiol -produced by the mature ovarian follicle- and induces proliferation and thickening of the endometrium.</em>

Approximately on the 15th day of the menstrual cycle, the egg is released and it is the time when it can be fertilized by a sperm to produce the zygote, which will start a pregnancy in women.
