Answer:
Mylein Sheath
Explanation:
what are the bonds that hold two animo acids together called ? A.peptide bonds B.double bonds C. oxygen bonds D. ionic bonds
Answer:
Peptide bonds are the bonds that hold two amino acids together.
Hope its helpful!
The bonds that hold two amino acids together are called peptide bonds. Therefore option A is correct.
Peptide bonds are a type of covalent bond formed between the carboxyl group (-COOH) of one amino acid and the amino group (-NH2) of another amino acid.
During a process called dehydration synthesis or condensation reaction, the carboxyl group of one amino acid combines with the amino group of another, releasing a water molecule and forming a peptide bond.
This process links amino acids together to create polypeptide chains, which are the building blocks of proteins. The sequence and arrangement of amino acids in a protein determine its unique structure and function.
Therefore option A is correct.

In the ovary, oocytes are held at metaphase II of meiosis until fertilization. How is this block released
In the ovary, oocytes are held at metaphase II of meiosis until fertilization.This block released, when Progesterone activates c-Mos, which further phosphorylates maturation promotion factor (MPF).
Maturation promoting factor :
One of the major protein kinases that activates and acts as the master regulator for the M-phase transition is Cdk1/cyclin B, also known as maturation promoting factor or MPF. It phosphorylates and activates other downstream protein kinases and directly phosphorylates several structural proteins involved in cellular reorganization.
It also play a major role in chromatin condensation by phosphorylating condensins; a role in NEBD by phosphorylating lamins, nuclear pore complexes, and inner nuclear membrane proteins; a role in fragmentation of the Golgi apparatus by phosphorylating Golgi matrix proteins; and a role in spindle formation by phosphorylating centrosome-associated proteins and MAPs.

If the overall diversity of a population is measured that had gone through a recent bottleneck and then rapidly recovered its former population size, it would have a lower than expected diversity based on its population size.
What is Population Bottleneck?A population bottleneck is a situation where the population is substantially reduced. A variety of occurrences, such as an environmental catastrophe, the extinction-level hunting of a species, or the destruction of an organism's habitat, might result in the bottleneck. Due to the loss of many alleles, or gene variants, present in the initial population, the population's gene pool decreases as a result of the population bottleneck. The event has resulted in an extremely low amount of genetic variation in the remaining population, which indicates that the population as a whole has few genetic traits.When a population bottleneck occurs and there are alleles present, the residual population is more susceptible to genetic drift.

A newly discovered species of bird is found to only lay a single egg and both parents are necessary to raise the chick to adulthood. What would be the most successful mating strategy for this species
monogamous is the answer.
When birds are vigilant, they rub together the swollen cloaca. The male sperm stored in his cloaca deposits in the female cloaca, where it travels up the chamber and eventually fertilizes the egg.
Most birds mate for only one season and for one reason. However, some species mate for life, while others mate multiple times during the season. Goose, swan, and eagle are known to have only one companion until one of them dies.
Monogamous is a mating system in which one adult male and one adult female are mated. Such a pair of turns can follow a single breeding attempt, breeding season, or many breeding seasons, such as mating mammals, geese, and swans.

In most cases along the nephron, the driving force in the reabsorption of solutes is the downward concentration gradient of -ATPase, which is localized in the basolateral membrane.
Ion Transport in the Kidney TubulesThe -ATPase, which is located in the basolateral membrane, is the main enzyme that drives Na+Cl reabsorption, according to the current review of the subject.As a result of the tiny ionic gradients that form in the proximal tubule, where bulk reabsorption occurs, the transport here is so cost-effective. As a result of Na+Cl- being reabsorbed and water being unable to follow, the TAL already has less efficient transport, but this nephron segment builds up ionic gradients (the urinary concentrating mechanism).

The theory of evolution by natural selection requires variability of a given trait. Why is variability necessary and where does it come from
Genetic variation is required for natural selection to operate. If all individuals possessed the same feature, there would be no relative variation in their reproductive success because they would all be equally suited to their environments.
A population's genetic variation can be measured to provide an idea of the range of genetic differences that are present in that community.
The genetic variation that exists throughout an entire species is typically referred to as the species' genetic diversity. Individuals might have distinct genetic variants due to variances in the DNA segments or genes they inherited from their parents. These variations are referred to as alleles. A population, for instance, is said to have a high level of genetic variety when there are many distinct alleles present at a single chromosome site. Natural selection can only increase or reduce the frequency of alleles that already exist in a population.
Mutations, which change the order of genes in DNA, are one way that genes can be different. Another source is gene flow, which is when genes move from one group of organisms to another. Lastly, sexual reproduction can cause genetic variation because it creates new combinations of genes.
