Why does the mitochondrial gene tree suggest a later split? Why the disparity between the nuclear gene tree?
this is the link: https://learn.genetics.utah.edu/content/evolution/bears/
Answers
Answer:
Why does the mitochondrial gene tree suggest a later split?The mitochondrial gene tree suggests a later split because it occurred hybridization later in time, with the transference of the brown bear mitochondrial genetic information to the polar bear population. So the mitochondrial gene tree exhibits a later divergence.
Why the disparity between the nuclear gene tree?Because the first divergence event of the common ancestor occurred 60,000 years ago, evidenced by nuclear DNI and mitochondrial DNI. However, 100,000 years ago, concerning the mitochondrial genetic material, the hybridization event defined a new more recent common ancestor between the two species.
Explanation:
The use of mitochondrial DNA might present a few problems that need to be considered in evolution studies. It involves only one locus, so it has some limitations when reconstructing history, especially if the locus went through any process, such as natural selection, bottleneck events, or its transference to another population due to hybridization. There is also a high possibility of an incomplete reconstruction of the population history if males and females have different dispersal patterns.
The most proper way of reconstructing history is by complementing mitochondrial information with nuclear genetic information and evaluating their concordancies.
In the exposed example, 600,000 years ago, the original species split into the polar bear and the brown bear. But 100,000 years ago, hybridization occurred between a brown bear female and a polar bear male. The offspring joined the polar bear population, carrying the female genetic information, nuclear and mitochondrial. With time, these individuals interbred with the polar bears, diluting the nuclear brown bear genetic information. However, females carrying the brown bear mitochondrial DNI seemed to be more successful reproductively than the polar bear females. The mitochondrial information, hence, has been in the population for many generations, until today. And this information came from a more recent common ancestor, compared with nuclear genetic information.

Explain why finding the average energy of the system would be a smarter way to record the temperature than giving the energy of each individual particle
Answers
Answer:
See Explanation
Explanation:
Temperature is defined as the average kinetic energy of the particles of a system.
In a system, there are several particles moving at various velocities and having various values of kinetic energy. It is very difficult to determine the individual kinetic energies of each individual particle.
Hence, we only need to obtain the average kinetic energy of the particles of the system in order to record the temperature.

Answer:
The answer is "Sympatric speciation due to disruptive selection"
Explanation:
Disruptive selection is a certain type of natural choice, that aggressively favors all ends of the spectrum in a moderate community. Disruptive selection is often deduced by a phyletic prepared to change to contribute to speciation. These two species happened due to various habitats associated with extreme speciation due to various confusing choices.

The heart doesn't have to do as much work to pump blood when in orbit. After only one day beyond Earth's gravity, astronauts have a lower blood volume. They can lose as much as 20 percent of their blood volume while on a space mission. Since the body has less blood to push around and the heart is pushing more blood with each beat, an astronaut's heart rate also slows down to compensate.

The oxygen and carbon dioxide exchange that occurs during photosynthesis and respiration help to
Answers
release carbohydrates
The oxygen and carbon dioxide exchange that occurs during photosynthesis and respiration aid in the release of carbon dioxide and the utilization of oxygen produced by the photosynthetic process.
What is the significance of respiration and photosynthesis?The photosynthetic process is the one that can make oxygen as a product, and later that oxygen is used by plants and other animals in the process of respiration, which is essential for life as the cell makes energy in this process. Plants and other chloroplast-containing photosynthetic organisms, such as blue-green algae, phytoplanktons, etc., can produce oxygen, which is then used in respiration to power the cell's activities.
Hence, the oxygen and carbon dioxide exchange that occurs during photosynthesis and respiration aid in the release of carbon dioxide and the utilization of oxygen produced by the photosynthetic process.

A gene has 2 alleles, R & B, List the possible genotypes? I also need help with questions 5, 6, 7 and 8 please help! Pls look at the picture! I will mark whoever sounds best the brain! Ty!
Answers
Answer:
5.) The possible genotypes should be: RR RB BB ( if the could for the same proteins)
6.) Frequency of R: 0.5
7.)Frequency of R: 0.5
8.)Frequency of R: 0.375
Explanation:
5.) If R and B code for the different forms of the same protein then they are only a few possible out comes
6.) First calculate the total alleles in population
allele R= 40
Allele B=40
total allele = R+B= 40+40
=80
Now to find allele R frequency is:
(Total R alleles) / (Total allele in pop)
40/80=
0.5
7.)Calculate the total alleles
Alleles from for R
RR= 10
R=10x 2= 20
Multiply the value by 2 because there are 2 R alleles present in
RB=20
R=20
Number doesn't change there is only 1 R allele
Total R=20+20
=40
Alleles For B
BB=10
B=10×2
=20
Same thing here, two B alleles together so multiple by 2
RB=20
B=20
Total B= 20+20
=40
Total alleles in pop add
40+40
=80
Frequency of R
Total of R/Total Alleles
=40/80
=0.5
8.)Repeat the same thing in 7 but use different numbers
RR=10
R=10x2
=20
RB=10
R=10
Total R= 20+10
=30

Answers
Answer:
The high sugar content caused too much water to move out of the root cells.
Explanation:
Too much causes transpiration to occur, in this case too much water killed the plant.
The statement which explains why the plant in Group E and F died is that the high sugar content caused too much water to move out of the root cells.
What do you mean by High sugar content?
High sugar content in plants may be defined as the amount of carbohydrates (glucose) and their components get accumulated in the different parts of the plants in a high ratio. It also affects the rate of photosynthesis.
High sugar content leads to the loss of water (transpiration) in plants. In this condition, water loss is maximum which results in the scarcity of water in the root cells. And hence the plant died.
Therefore, the statement which explains why the plant in Group E and F died is that the high sugar content caused too much water to move out of the root cells.
