Read the following summary, which describes blood flow and heart output in space. Then, answer the question.
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.

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/
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.
Write at least 3 sentences explaining why plants are so important to humans. *
Answer:
Please mark brainliest :)
Explanation:
Plants provide oxygen for humans through photosynthesis. They can store carbon which is a greenhouse gas. Plants are a staple in humans' diets. Bonus: They are a source of income for farmers. They hold important vitamins. They can be beneficial to healthy soil and keep it from blowing away or eroding.

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!
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
8. For the food chain shown below, which of the following changes would 2 points
have the most severe consequences? Grasses - Crickets → Field Mice →
Hawks
A minor decrease in rainfall
The field mice population slightly increasing
The introduction of a second predator that eats field mice
0 A parasitic infestation that reduces the cricket population
Answer:
I think it is A Parasitic one
Explanation:
A decrease in rainfall may lead to drought, thereby altering the basis (first level) of the food web.
A food web is a diagram that represents the relationships between different groups of organisms in an ecosystem.Producers (e.g., plants) are organisms that maintain the entry of matter and energy to the food web.Rainfall is fundamental for maintaining the life of land producers (in this case, grasses) in the food web.In conclusion, a decrease in rainfall may lead to drought, thereby altering the basis (first level) of the food web.

The oxygen and carbon dioxide exchange that occurs during photosynthesis and respiration help to
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.

Explanation:
TAC GGG AGT CTT TCC ACT -DNA
AUG CCC UCA GAA AGG UGA -mRNA
Met Pro Ser Glu Arg Stop -Amino acid sequence
Can't see the bold :/
Insertion mutation I believe.
A codon chart can be used to read the genetic code. To utilize this chart, start by finding the first codon nucleotide, then the second, and finally the third. The chart will then show which codon codes for the amino acid. Because the genetic code is degenerate, there are several codons for each amino acid.
What role of genetic code in DNA sequence?The genetic code serves as the body's language for converting the DNA instructions from our genes into the constituent parts of life. It is typically discussed using the “codons” found in mRNA since mRNA is the messenger that transmits information from the DNA to the site of protein production.
Therefore, TAC GGG AGT CTT TCC ACT -DNA
AUG CCC UCA GAA AGG UGA -mRNA
Met Pro Ser Glu Arg Stop -Amino acid sequence

Answer:
2.
Explanation:
they needed less skin surface area touching the cold and more wider body shape so that it can keep warm its body, like how fat people are basically insulated and have a coat around their organs
Answer:
2. because they migrated to Europe with a colder climate

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
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.

Which prezygotic mechanism most likely allowed divergence of an ancestral species into these present-day species
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.
