What is an example of an elevation change

Biology
1 answer:
Olegator [25]2 years ago
5 0

<em>For example,</em>

<em> consider a mountain whose summit is 5,000 feet (1,500 m) in elevation, but somewhere on the way up, the trail goes back down 250 feet (76 m). ... </em>

<em>If one hikes over five hills of 100 vertical feet each, the cumulative elevation gain is 5 × (100 feet (30 m)) = 500 feet (150 m).</em>

Arturiano [62]

Answer:

The best explanation for the increased lymphocyte levels in Kaya is that she was not tissue typed prior to her surgery, and her body is mounting an immune response.

Explanation:

When performing an organ transplant, it must be verified whether the organ to be transplanted is compatible -by tissue typing- with the recipient, since it is recognized as a foreign body by the body and can be rejected.

One of the immunological responses to organ rejection is called cell rejection, involving T-helper and cytotoxic lymphocytes.

<u>It is very likely that in Kaya's case the tests have not been performed correctly, and she is experiencing rejection of the organ she received</u>. The progressive increase in lymphocytes may be an indication of this.

The other options are not possible because:

  • <em>Administering </em><u><em>antibiotics</em></u><em> should not raise lymphocyte levels. </em>
  • <em>There is no evidence of </em><u><em>antigen </em></u><em>attack. </em>
  • <u><em>Immunosuppressant drugs</em></u><em> do not increase lymphocyte count.</em>

Please HELP!! Place the events 1 to 7 in order of how they happen during speciation.
hoa [83]

Answer:

6, 3, 4, 5, 7, 2, 1

Explanation:

Here, speciation occurs because the original butterfly population gets separated into two populations, each facing a different set of environmental conditions. Initially, there was just a single population of butterflies in the valley and all butterflies were able to mate with each other. A fire destroyed their habitat so they had to migrate to other areas. Some butterflies migrated to eastern side of mountain and some to western side of mountain.

Now there were two butterfly populations and they faced different environment from each other. Over the time, the populations adapted to their local surroundings and started to accumulate changes in their genome. Their gene pools started to separate from each other. Eventually they evolved into two different species. When their old habitat was restored in the valley, they returned once again. However, this time they were not able to interbreed because they were now two different species.

Why are there more males than females with the krabby-blindness trait?<br>​
Over [174]

Answer:

Because males are never carriers for x-linked trait, only females are carriers which gives them a lower chance of receiving the trait. While males can either have the trait or not have it.

How is a lysogenic cycle different from a lytic cycle
Rudiy27

The difference between lysogenic and lytic cycles is that, in lysogenic cycles, the spread of the viral DNA occurs through the usual prokaryotic reproduction, whereas a lytic cycle is more immediate in that it results in many copies of the virus being created very quickly and the cell is destroyed.

Please mark brainliest. :)
