The Tibetans and Han Chinese share several genetic traits and DNA. However, the EPAS1 gene, which increases the ability of red blood cells to carry oxygen even in low oxygen environments, is only commonly found in the Tibetan population that live in higher elevations. Explain why this gene is only common in Tibetan populations from the perspective of competitive advantage and natural selection. Write your answer in three to five sentences.(4 points)
Answer:
When in higher altitudes, ticker blond has a tendency to cause problems like heart attack's, however the Tibetans have adapted to the high altitudes and this has made their blood thinner in order to keep them safe in the altitudes, including that it has low oxygen rates in the altitude therefore providing more oxygen in the bloods cells.
Explanation:
:D It's not my best explanation but I hope this helps <3.
Owing to the fact that ability of the redblood cells to to carry oxygen even in low oxygen environments is neccessary at high elevations, the Tibetan population that live in higher elevations are found to possess the EPAS1 gene.
What is natural selection?The term natural selection refers to the fact that organisms that are better adapted to their habitat will live longer and reproduce. Now we have to note that owing to the elevation at which they live, the people that possess this EPAS1 gene can cope with oxygen stress that could likely occur at a high altitude.
As such, the Tibetan population that live in higher elevations are found to possess the EPAS1 gene.

Where can proteins be found when part of a plasma membrane?
Answer:
Peripheral membrane proteins are found on the outside and inside surfaces of membranes, attached either to integral proteins or to phospholipids. Unlike integral membrane proteins, peripheral membrane proteins do not stick into the hydrophobic core of the membrane, and they tend to be more loosely attached.

why does a male body produce more testosterone than a female's body
Answer:
Levels depend on a person's age, sex, and health. Males usually have much higher levels of testosterone in their body than females
Explanation:
As the metabolism of testosterone in males is more pronounced, the daily production is about 20 times greater in men. Females are also more sensitive to the hormone

The government wants to set new regulations that prohibit chlorofluorocarbons (CFCs) use in aerosol sprays and refrigerants. How will this act help with the sustainability of our environment?
Answer:
The new regulation will help reduce the amount of green house gases available in the atmosphere thereby saving our environment from the Green house effect
Explanation:
Chlorofluorocarbons are examples of greenhouse gases which contribute to the Green house effect been experienced in our environment, by destroying the earths' Ozone layer
If the Government sets a new regulation that prohibit its use in sprays and refrigerants it will help reduce the amount of green house gases available in the atmosphere thereby saving our environment from the Green house effect
Answer:
that act will help the sustainability of out environment because : C. It will slow down the degradation of the ozone layer
The usage of CFC will crate chlorine atoms that catalyze ozone degradation. By prohibiting this product, Government will slow down Ozone's degradation

The most likely reason(s) a metastatic tumor cell might lose its connection to the basal lamina would be: a change in the integrin proteins from the cell's surface. a change in the cadherin proteins on the cell surface. a change in connexins disrupting gap junctions. All of these choices are correct.
Answer:
A change in the integrin proteins from the cell's surface.
Explanation:
Integrin proteins' principal function is to attach the cell to the basal lamina. Also, they transmit signals from the extracellular matrix to the interior of the cell. A change in the integrin could result in loss of connection between the mutated cell and the basal lamina.
Cadherin proteins connect one cell to another. A change in these proteins will not result in the loss of connection between the metastatic tumor cell and its extracellular matrix. It most likely will affect the communication and adhesion of cells.
A change in connexins will disrupt the communication between cells but not the connection to the lamina basal. Connexins are transmembrane proteins that connect one cell to another with gap junctions that allow the passage of different components from cell to cell.
What is the difference between the original strand of DNA and the mutated
strand?
(HELPP)
Answer:
An original section of dna has the base sequence agcgttaccgt. A mutation in this dna strand results in the base sequence aggcgttaccgt. This change represents a frameshift mutation. It is a genetic mutation caused by indels (insertions or deletions) of a number of nucleotides in a DNA sequence that is not divisible by three.

Answer:
Explanation:
For the 1st one with the Cheetah: It would be a long tail because it helps them balance when they turn. Sinch Cheetahs move extremely quickly they need a balance to ensure they don't topple over when they turn, this tail provides this balance.
For the 2nd one with the bear: Thick coats on a bare will help provide warmth whenever they go to hybernate. Thin fur would leave room for freezing and wouldn't be able to help them maintain the proper body temperature.
The 3rd one with the clownfish: A round tail provides a bigger boost when swimming since it is able to push more water. A forked tail would create a gap when they swim so they would have to expend more energy than with a round tail.
The 4th one with the Finch: Since grubs live underground a thinner beak would be able to dig them out and stab them faster. This allows them to reach farther and get more food.
