What is Anatomy and why is it important for evolution?
Answer:
Anatomy is the branch of science concerned with bodily structure of humans, animals, and living organism,especially as revealed by dissection and the separation of parts. It is important for evolution because it determines the evolutionary relationship between organisms and weather or not they have something in common.
What kind of information does DNA store?
Answer:
biological information
Explanation:
DNA is found in almost every cell in the human body. It stores biological information, such as eye color, hair color and skin tone. The genetic data contained in DNA serves as a blueprint for each cell to perform its functions. So, DNA essentially 'programs' the human body

Answer:

Explanation:
The blue people of Troublesome Creek Kentucky were genetically isolated from the rest of the world for generations. A rare recessive allele that causes people to have a blue tone to their skin, methemoglobinemia, became disproportionately common within this population by way of their genetic isolation. In the last few decades new roads opened leading to the end of this communities isolation. To the surprise of many, the methemoglobinemia phenotype disappeared along with their genetic isolation. Which of the following may best explain the apparent disappearance of this once common trait?
a. Methemoglobinemia did not confer any physical advantage so that the trait was selected against.
b. Methemoglobinemia was probably lethal and all those that carried this trait died and did not have a chance to pass on this trait to future generations.
c. Those that had the traits simply did not have descendents.
d. With the end of genetic isolation gene flow took place.
Answer:
The correct answer would be - d. With the end of genetic isolation gene flow took place
Explanation:
It is given that people of Troublesome Creek Kentucky were isolated and have a rare recessive allele that results in a blue tone to their skin. However, later these isolated people connected with the people from outside, and due which allow them to intermate. Intermating among populations from isolated and people from outside leads to gene flow.
Methemoglobinemia was present in the isolated population as they had both recessive alleles in their genotype and other hand people from outside might have heterozygous or both dominant allele genotypes that make them free from this disorder.
Due to the intermating and gene flow, the number of heterozygous conditions rises and after many generations slowly methemoglobinemia could have disappeared due to the masked recessive allele.

how is mitosis different from mitosis
Answer:
Mitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell.

Homologous recombination occurs in a heterozygote in which alleles D and d differ by a single base pair. The D allele has a G (a GC base pair) at one position, whereas the d allele has a C (a CG base pair) at the same position. If branch migration causes heteroduplex formation across this position, what is the expected outcome
Answer:
Mismatch DNA repair mechanism recognizes the abnormal base pairing (G-G base pair) and may correct it by converting the D allele to d
Explanation:
The DNA mismatch repair can be defined as a specialized mechanism that recognizes and repairs errors in the nuclotide sequence (such as, for example, bases erroneously incorporated) during DNA replication and recombination. The DNA mismatch repair is a system that also acts to repair the DNA after damage. It has been shown that the DNA mismatch repair mechanism leads to the generation of a DNA molecule with one chain that has the nucleotide sequence arising from DNA repair and one parental chain. In this case, it is expected that the DNA mismatch repair mechanism will identify the abnormal G-G base pairing and then this system may change the D allele to a d allele by introducing a C base instead of a G base in the DNA strand.

What type of mutation has occurred?
A) deletion
B) insertion

Since 1953, when Tenzing Norgay and Edmund Hillary reached the summit of Mount Everest, many climbers have attempted to scale the world's two highest mountains, Everest and K2. Norgay and Hillary aided their climb by bringing supplemental oxygen in tanks, and some later groups have attempted to outdo the originals by trying the ascent without supplemental oxygen. From 1978 to 1999, in fact, 159 teams have attempted to climb Mount Everest or K2. The numbers of individuals who either survived or died during those attempts are given in the following table (data is hypothetical and not the exact numbers observed by Huey and Eguskitza 2000).
Survived supplemental O2 (16) No Supplemental 02 (175), did not survive (38) (192) - seen in 2 by 2 table, amounts are in parathesis

Darwin suggested that plants pollinated by long tongued insects would benefit by having long flowers. To measure the advantaged of having long flowers, Johnson and Steiner (1997) experimentally shortened 68 of 140 flowers. The remaining flowers were control. One week later, 24 out of the 68 shortened flowers had received pollen, whereas 18 out of the control flowers had received pollen. Estimate the odds ratio of not receiving pollen after flower shortening, as compared to control flowers
Answer:
The possibility of not receiving pollen for shortened flowers is 64.7% and for the control group it is 75%.
Explanation:
Pollination carried out by insects help plants spread their pollens and multiply. Contrary to Darwin's suggestion, the experiment results prove that having long flowers decreases the chances of pollination by long tongued insects as it is shown in the experiment.
The odds ratio of not receiving pollen after the flower shortening can be calculated as 64.7% compared to the odds of flowers that were not shortened which have a possibility of 75% of not receiving pollen.
I hope this answer helps.
You are studying a new gene "X" that you think controls skin color in Bearded Dragons. In order to determine what gene X does you need lots of gene X DNA to work with. So, you decide to amplify it through the process known as PCR. You have a forward and a reverse primer that have been designed to gene Xf – a gene in frogs that is similar to the one found in the Bearded Dragon. You are pretty sure that these two primers will work in Bearded Dragons, so you decide to go ahead with the PCR. In frogs, the Forward Xf primer binds gene Xf between nucleotides 32 and 47. The Reverse Xf primer binds between nucleotides 1110 and 1135. What size PCR product would these two primers create if they amplified the frog gene Xfp
Answer:
The correct answer is - 1103 bp.
Explanation:
PCR or polymerase chain reaction is a process that uses a primer to amplifying the desired segments of DNA molecules. It is a technique that can amplify a million copies of the DNA segment.
given:
forward primer binds from - 32 to 47
reverse primer binds from - 1135 to 1110
PCR product would be between - 32 to 1135
So, product size would = 1135-32 = 1103.
Thus, the correct answer is - 1103.

D.
a cell that possesses the ability to change its shap
The description best describes a squamous-shaped cell, a cell that is taller than it is wide a spherical-shaped cell a flattened, scalelike cell. The correct option is C.
What is a cell?
A cell is the basic unit of life. It is the smallest unit from which all living matter is made up of. It contains cell organs, and it performs many functions of the living bodies.
Cells are of different types and different shapes. Squamous-shaped cells are flattened, thin cells, and their nuclei are oval-shaped due to less space. They are called squamous epithelial cells.
These types of cells are present in the layers of skin and alveoli of the lungs. They help in passive diffusion.
Thus, the correct option is C. a flattened, scalelike cell.
