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)

Answers

Answer 1

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.

Answer 2

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.

Complete question:

A geneticist crossed fruit flies to determine the phenotypic ratio. The geneticist crossed a fly with blistery wings and spineless bristles (bbss) with a heterozygous fly that had normal wings and normal bristles (BbSs). Which proportion of offspring that are dominant for both traits in would you not expect based on Mendel's law of independent assortment? 1/2 , 4/16, 25% , or 1/4

Answer:

1/2 is the proportion of the offspring that is NOT expected among individuals that are dominant for both traits.

4/16 = 1/4 = 25% of the progeny and the correct expected proportion of individuals that are dominant for both traits.

Explanation:

Available data:

Cross:  a fly with blistery wings and spineless bristles with a heterozygous fly that had normal wings and normal bristles Recessive trait: blistery wings and spineless bristlesDominant trait: normal wings and normal bristles

Let us say that:

B is the dominant allele for normal wingsb is the recessive allele for blistery wingsS is the dominant allele for normal bristless is the recessive allele for spineless bristles

F1)  4/16 = 1/4 = 25%  of the progeny is expected to be BbSs, dyhibrid individuals, expressing normal wings and normal bristles

     4/16 = 1/4 = 25% of the progeny is expected to be Bbss, expressing normal wings and spineless bristles

     4/16 = 1/4 = 25% of the progeny is expected to be bbSs, expressing  blistery wings and normal bristles

Answer:

Collect some data about the distribution of the explosive.

Explanation:

Following 9.06's Scientific Method Lab, we can see that what Adams has done is ask a question: who set the explosive?

The next step of the scientific method would be conducting research, followed then by forming a hypothesis. So the answer is collect some data about the distribution of the explosive, as that falls under conducting research.

porque los alimentos se oscurecen?(platanos, palta, manzana, papa, etc) respondan pls✋

Answers

Answer:

Una enzima es una sustancia, generalmente una proteína, en la célula de un organismo que acelera las reacciones químicas.

Durante el pardeamiento enzimático, una enzima llamada fenolasa y otro compuesto orgánico que se encuentra en las células de la fruta llamados fenoles pasan por una reacción de oxidación cuando se exponen al oxígeno. La fenolasa regula la reacción, convirtiendo los fenoles en melanina.

Por lo general, las enzimas de la fruta están encerradas en tejido. Las enzimas están metidas en sus células, trabajando para madurar la fruta. Pero cuando esas células se descomponen, ya sea por una causa externa como si alguien muerde o corta la fruta o por causas naturales como el envejecimiento, las enzimas se liberan y entran en contacto con el oxígeno, lo que desencadena la reacción química y hace que la fruta se vuelva marrón.

A population of deer has a carrying capacity of 875 deer, with a maximum rate of increase of 1.0 per individual per year. Using the logistic population growth model, what is the approximate population growth rate for a population of 420 deer?
148 deer per year
218 deer per year
307 deer per year
474 deer per year

Answers

Answer:

Option B, 218 deer per year

Explanation:

As we know

[tex]\frac{dP}{dt} = kP (1- \frac{P}{K})[/tex]

Where K is the carrying capacity

K is the rate constant

dP/dt is the change in population per unit time and

P is the population

Substituting the given values we get

[tex]\frac{dP}{dt} = k * 420 * (1-\frac{420}{875})\\= 1 *420 * (1-0.48)\\= 218[/tex]

Option B is correct

if a vector not have origin of replication result in what

Answers

Answer:

What will be the consequence of not having an origin of replication (ori) in the vector? Explanation: In the case ori is absent, the vector won't be able to replicate

Explanation:

As the replication won't take place, only one of the daughter cells would be having the vector. A colony of transformed colonies won't be obtained.

if a vector does not has the origin of replication result in not doing replication as the unit of replication is Ori.

In the case Ori is absent, the vector may not be capable of replicating. As the replication may not take place, the handiest one of the daughter cells might be having the vector. A colony of converted colonies may not be obtained.

What is transgene?

Of these, the maximum usually used vectors are plasmids. Common to all engineered vectors have a foundation of replication, a multi cloning site, and a selectable marker. The vector itself is normally a DNA series that includes an insert (transgene) and a bigger series that serves as the "backbone" of the vector.

Thus it is clear that if a vector does not have an origin of replication result in nonreplicating.

How do you suppose changes in DNA lead to speciation

Answers

Answer:

The correct answer is - change in DNA is called mutation which is essential for evolution including speciation.

Explanation:

A mutation is a change in the genetic or hereditary material which is DNA. A mutation is the main reason behind the evolution of the organism or species and speciation can be led by evolution, which takes place by results in the accumulation of many small changes in DNA or genetic changes in a population over a long period of time.

Mutations that change in DNA are required for the evolution process they are the raw material of genetic variation. without changes in hereditary material, there is no speciation or evolution possible.

Cell includes a cell membrane, cytoplasm and cell organelles. Cell organelles are mitochondria, golgi bodies, nucleus, ribosomes, vacuoles, lysosomes, centrioles, etc.

What are cell organelles?

Cell organelles are the structures present in cell that are responsible to carry out necessary processes and maintains homeostasis.

This can include nucleus, mitochondria, golgi bodies, ribosomes, etc.

Nucleus: Nucleus is a membrane bound cell organelle that contain an entangled thread like structure called as chromatin material. This chromatin material condenses at the time of cell division and forms chromosomes. Nucleus also contain nucleolus that helps in formation of ribosomal units. it contains a fluid called as nucleoplasm.

Ribosome is the organelle that is involved in formation of protein. It has two subunits i.e. a smaller one and a bigger one. these subunits are joined at the time of protein synthesis and are formed in nucleolus of nucleus.

Thus, these were explanation of two cell organelles along with their explanation.
