1c) If the amino acid sequences in the proteins of 2 organisms are similar, why will their DNA also be similar?
Trava [24]

Answer and Explanation:

Because the DNA sequence determines a protein's amino acid sequence, a gene shared by two closely related organisms should have similar, or even identical, amino acid sequences. That's because closely related species most likely diverged from one another fairly recently in the evolutionary span. Thus, they haven't had as much time to accumulate random mutations in their genetic codes.

Priya has been having trouble conceiving. She went through testing at a fertility clinic and found that everything seemed fine w
NARA [144]

Answer:

A. Estradiol

Explanation:

Estradiol, which is also referred to as 17 beta-estradiol, is an estrogen steroid hormone. This form of estrogen is one of the major female sex hormone that plays major role in the female reproductive system such as regulation of the estrous and menstrual cycle. It also helps in regulating body metabolism.

Reduction in the level of Estradiol is one of the problems common in women approaching menopause. Optimal level of estradiol in the body helps improve fertility in the body as symptoms such as such as vaginal dryness, burning, itching that are associated with menopause are reduced to the barest minimum.

The supplement taken by Priya in order to thin the mucus and allow sperm to get through the mucus to the uterus most likely works to benefit the body by increasing <em>estradiol.</em>

How is a mantle plume (hot spot) different from volcanoes in the Ring of Fire? How are they similar? Give one specific example o
riadik2000 [5.3K]

The difference between a hot spot volcano and the volcanoes from Ring of Fire can mainly be seen in the way of formation and functioning. The hot spot volcanoes are far away from any tectonic plate boundary and they manage to penetrate the crust over them and come out on the surface to usually create volcanic islands. The activity of the volcanoes from the Ring of Fire depends directly from the activity between the bordering tectonic plates, and as the borders move over time, the volcanoes stop existing, and new ones rise in the direction where the boundary moves.

The similarity can be seen in the type of eruptions, and that usually both types of volcanoes form volcanic islands.

Example for a hot spot volcano is Mauna Loa on Hawaii.
