Any estimate of the heritability of a particular trait is specific to one population in one environment.
The degree to which genetic variations among persons may adequately explain the variations in their attributes is known as heritability. Characteristics like height, eye color, and IQ are examples of traits, as are illnesses like schizophrenia and autism spectrum disorder.Heritability, which is denoted by the statistic h2 in science, describes the proportion of a trait's variation that can be attributable to genetic variation. An estimation of a trait's heritability is particular to one population in a particular setting, and it might alter over time as conditions change.Between 0 and 1 heritability estimates are given. A heritability near to zero indicates that environmental variables, rather than genetic differences, account for the majority of variation in a trait among individuals. Due to their lack of genetic control, traits like religion or spoken language have a heritability of zero. A heritability near to one means that genetic differences account for almost all of the variability in a characteristic, with little to no influence from environmental factors. High heritability is a characteristic of many diseases, including phenylketonuria (PKU), which is brought on by variations (also known as mutations) in a single gene.learn more about heritability here: https://brainly.com/question/6965635

Which hormone released by the highlighted structure inhibits the secretion of fsh only inhibin?
Inhibin hormone released by the highlighted structure inhibits the secretion of FSH only.
What is inhibin hormone?A protein called inhibin is secreted by the granulosa cells in women and the Sertoli cells in men. It decreases the amount of LH-releasing hormone in the hypothalamus and prevents the pituitary gland from producing and releasing follicle-stimulating hormone.Inhibin is a factor in the feedback control of FSH secretion in both males and females going through puberty. Follistatin suppresses FSH-subunit expression like inhibin, whereas activin enhances it, which in turn influences FSH production and secretion.Inhibin A is secreted by the corpora lutea and dominant ovarian follicles in women, which helps to explain why levels are so high during the late follicular and luteal stages. During the late luteal and early follicular phases of the menstrual cycle, inhibin B is reciprocally raised.Learn more about inhibin here:

One advantage of branched sugar polymers is the availability of more ends for chemical reaction.
a. true
b. false
The one advantage of branched sugar polymers is the availability of more ends for chemical reactions. So, the statement is true.
What are branched sugar polymers?Polysaccharides are simply the monomers of thousands of monosaccharides units. The kind of polysaccharide formed will be based on the kind of monosaccharide units involved.
The branching of monomers helps in the formation of polysaccharides. Branching of glucose monomers in the formation of different polysaccharides. These are starch and cellulose present in plants and glycogen in animals.
These kinds of polysaccharides are made of a lot of monomers and that is caused by the branching. This kind of branching can also help in the addition of more monomeric units to make a longer polysaccharide chain.
Therefore, an advantage of branched sugar polymers is the availability of more ends for chemical reactions.

What are the chemical changes that occur in your blood that will potentially stimulate an increase in ventilation during and shortly after exercise?
More CO2 and H+ is generated, enhancing oxygen unloading in the muscles in the process.
When you exercise and your muscles work harder, your body uses more oxygen and produces more carbon dioxide. To cope with this extra demand, your breathing has to increase from about 15 times a minute when you are resting, up to about 40–60 times a minute during exercise.
The gas exchange requirements of the lung increase due to an increased oxygen consumption and increased carbon dioxide production. In addition, both the respiratory rate and tidal volume increase, hence alveolar ventilation also increases. This increases the rate of gas exchange and minute volume.

Disruptive selection acts to eliminate individuals which are intermediate on a phenotypic range.
What is disruptive selection?Extreme values of a trait are preferred above intermediate values in population genetic alterations known as disruptive selection, also known as diversifying selection. In this situation, the trait's variation rises and the population is split into two clearly defined groups.A population that has two extreme variants of a trait as the dominant phenotype is the result of disruptive selection. For instance, disruptive selection would be in play if both short and tall species, but not medium-sized organisms, were favored.A type of natural selection in which traits with extreme values are preferred over those with moderate values.A type of natural selection known as stabilizing selection is one in which genetic diversity declines as the population stabilizes on a particular trait value.Natural selection that discriminates against the typical person in a population is known as disruptive selection.

What might happen if a substance that is not a substrate molecule binds to an enzyme's active site?
If a substance which is not a substrate happens to bind to the active site of an enzyme, it will result in the reduction of the activity of the enzyme.
For an enzyme to catalyze a reaction, a substrate has to come and bind to the active site which is present on the enzyme. As the substrates binds, some modifications occur resulting in a change of shape of the active site and results in the grasping of the substrate more tightly and thereby catalyzing the reaction.
If a substance which is not a substrate comes and takes the place of the substrate on the active site, the rate of the reaction will slow down as the active site will now not be able to bind to the target molecule.

What three key observations allowed darwin to deduce that natural selection is a primary driver of evolution?
Populations of organisms vary, more offspring are produced than can survive, and the relative frequency of favourable mutations rises with time.
What is natural selection?Natural selection is the variation in individual survival and procreation brought on by phenotypic variances. The evolution of a population's heritable features across generations is a fundamental mechanism of evolution. By contrasting it with artificial selection, which in his opinion is intentional and natural selection is not, Charles Darwin popularized the phrase "natural ."

Recent discovery of endogenous synthesis of peptidoglycan in eukaryotes stated that the amount of PG difference between animals and bacteria becomes quantitative and no longer qualitative.
