Food- Most Ag animals, (Such as farm animals) Are mainly a source of food. This role is vital to my life and everyone else because Food is one of the major things we need for life. This item is produced through farming and Manufacturing. The main contributors to this would be Cows, Sheep, Pigs and Chicken.
Clothing- Some animals fur or Wool can be used as a type of base material for clothing. This Role is vital to my life and everyone else because Clothing is one of the major things we need for life. This item is produced through Shearing, Hunting and/or Manufacturing. The main contributors would be Sheep, but sometimes game animals (such as bears or deer) are used too
Milk- Cows and Some goats Makes milk. This is an important role because Milk is used in a variety of foods such as Cakes, Cereal, Oatmeal, etc. The main contributor would be Cows, however some times Goats milk can be used as well. Milk is mainly processed through pasteurization
Pets- Some animals (cats, dogs, birds, etc.) Can be used as Pets. This role is important because Pets are Stress relievers and can help mentally with what could go on around the world. Most pets are breed through selective breeding. The main contributors are Cats, Dogs and Fish.
Butter- Animal fat can be used to make butter. This is a important role because butter is also used in a variety of foods, such as cakes, Meats, etc. Animal fat left over from butchering animals can be process into butter. Most ag animals that are used for meat, (cows pigs) are used. A second way to make butter would be to use goats milk.

What is Nucleotide?Nucleotides are defined as organic molecules composed of a nitrogenous base, a pentose sugar and a phosphate, which serve as the monomeric units of nucleic acid polymers such as deoxyribonucleic acid and ribonucleic acid, which are essential for all life-forms. There are essential biomolecules inside the Earth.
The sugar and phosphate groups which form the backbone of the DNA double helix, while the bases are located in the middle, a chemical bond between the phosphate group of one nucleotide and the sugar backbone of a neighboring nucleotide hold it together.
Therefore, the correct option is D.

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.

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.

4. Analyze: Compare the offspring traits to the parent traits.
A. Which traits were passed from parents to offspring? __________________________
B. Which traits were not passed down? ______________________________________
Traits that are not passed down (not inherited) are called acquired traits.
Answer: 4a. The transmission of characteristics from parents to offspring is called heredity, and the characteristics that are inherited can be predicted. 4b. An acquired characteristic is a non-heritable change in a function or structure of a living organism caused after birth by disease, injury, accident, deliberate modification, variation, repeated use, disuse, misuse, or other environmental influence. Acquired traits are synonymous with acquired characteristics.

A. the helper T-cells
B. the thymus
C. inherited DNA
D. the bone marrow
The directions for generating MHC comes from the option c. inherited DNA. hence, the option c is correct.
What is MHC?The full form is a major histocompatibility complex. It is the genes group that have the proteins code that should be founded on the cell surface which helped the immune system, that recorded in the foreign substance.
So at the time of directing, it produced MHC that came from inherited DNA.

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
Two species of three-spined stickleback fish have been found together in five different lakes. The larger, bottom-dwelling species feeds on large prey close to shore. A surface-dwelling species feeds on small plankton in open water. DNA analysis shows that the two species in each lake are more closely related to each other than they are to any of the other species in the lake. 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.
