Why is meiosis important for organisms?It creates gametes and allows for genetic variation among organisms.
It produces genetically identical cells.
0 It provides a means of asexual reproduction.
O It allows for cell and tissue repair

Answers

Answer 1

Answer: The correct answer is A. It creates gametes and allows for genetic variation among organisms.

Meiosis is the process of cell division in which a single cell divides into four daughter cells. The genetic constitution of the daughter cells reduces to the half as compared with the parent cells. While crossing over, an exchanging of genetic material is passed between chromosomes and that allow variations to happen.

The scientist anneals a mutant oligonucleotide to the original M13 DNA. Then DNA polymerase replicates the M13 DNA. After DNA synthesis, the scientist adds a restriction enzyme, EcoRI, that recognizes the DNA sequence 5′−GAATTC−3′5′−GAATTC−3′ and cuts after the guanosine nucleotide. Following the restriction digest, the scientist adds exonuclease III for a short period of time. Another round of DNA polymerase‑catalyzed DNA synthesis completes the procedure. What is the nucleotide mixture required by the DNA polymerase reaction in this procedure?

What is brain cancer ?

Answers

Answer:

Brain cancer is an overgrowth of cells in your brain that forms masses called tumors. Cancerous, or malignant, brain tumors tend to grow very quickly. The symptoms of brain cancer depend on the size and location of the tumor.

Common brain cancer symptoms include:

headaches that are usually worse in the morning

nausea

vomiting

a lack of coordination

a lack of balance

difficulty walking

memory lapses

difficulty thinking ,speech problems

.Many of the symptoms of brain cancer are also caused by other, less serious conditions. There’s no need to panic if you’re experiencing these symptoms, but it’s a good idea to visit your doctor to have your symptoms investigated, just in case.

All of the following are cofactors used in the reaction catalyzed by pyruvate dehydrogenase EXCEPT ________.A. NAD+
B. Thiamine pyrophosphate
C. Biotin
D. FAD

Answers

Answer: Option B.

Thiamine pyrophosphate.

Explanation:

Pyruvate dehydrogenase is an enzyme that catalyses the oxidative decarboxylation of pyruvate to acetyl coA , NADH and CO2. Pyruvate dehydrogenase uses NAD, biotin, FAD and lipoic acid.

Thiamine pyrophosphate is not a cofactor for pyruvate dehydrogenase . It is a cofactor in living systems. Thiamine pyrophosphate is a coenzyme that function in carbohydrates, Amino acids and lipids metabolism.

Final answer:

Biotin is not a cofactor in the reaction catalyzed by pyruvate dehydrogenase. NAD+, Thiamine pyrophosphate, and FAD do function as cofactors in this reaction.

Explanation:

The cofactors used in the reaction catalyzed by pyruvate dehydrogenase are NAD+, Thiamine pyrophosphate, and FAD. The compound that is not used as a cofactor in this reaction is Biotin. Biotin functions as a cofactor for carboxylase enzymes, and it is involved in fatty acid synthesis and gluconeogenesis but not in the process involving pyruvate dehydrogenase.

Actually it’s B. The hydrophilic heads attract water, which would mean water can be found above or below the structure

Water most likely to be found in the presence of the phospholipid bilayer above and below the structure because the heads attract water. Option B

why do the processes and events dating back to the big bang eventually led to the existence of life on earth

Answers

Answer:

Stars are formed such that their death led to the creation of life.

Explanation:

The Big Bang theory was developed in 1927. This theory helps to understand how the universe was created. According to this theory, hydrogen gas was created through a process of expansion and explosion. As a result, stars are formed such that their death led to the creation of life.

Earth formed around 4.54 billion years ago which is equal to approximately one-third of the age of the universe.

A woman ovulates but does not get pregnant. Trace the journey of the egg from ovulation torelease of the egg during menstruation. Put the following structures in order: cervix, fallopian
tube, ovary, uterus, vagina.

Answers

Final answer:

The journey of the egg from ovulation to release during menstruation includes the ovary, fallopian tube, uterus, cervix, and vagina.

Explanation:

The journey of the egg from ovulation to release during menstruation involves several structures in the female reproductive system. The process begins with ovulation, during which an egg is released from the ovary. The egg then travels through the fallopian tube, where it may be fertilized if sperm is present. If the egg is not fertilized, it continues to the uterus and is eventually shed during menstruation through the cervix and vagina.
