A student proposes that left-handedness is a recessive trait and is hidden in much of the human population. a survey of his class of 36 students finds that 9 students are left-handed. using the hardy-weinberg formula, what would be the expected allelic and genotypic frequencies in this theoretical population
The frequency of the recessive allele for the left handle will be in this case equal to q^2 = 0.25 >> q = 0.5.
What is the Hardy Weinberg principle?The Hardy Weinberg principle is a model used in population genetics to estimate genotypic and allele frequencies.
The Hardy Weinberg principle states that the sum of the dominant allele and the recessive allele in a population is equal to 1 (p + q = 1).
This principle also states p2 + q2 + 2pq = 1, where p^2 is the dominant homo-zygous allele, 2pq the heterozygous frequency and q^2 the recessive homo-zygous frequency.
In this case, 9 individuals represent 25% (q^2 = 0.25), thereby the feecuency of q is equal to √0.25 = 0.5.

Some snail species' shells can have right-handed direction of shell coiling or left-handed direction of shell coiling. The direction of coiling depends on a protein deposited by the mother in the egg cytoplasm with DD and Dd mothers depositing a protein that directs right-handed direction of coiling in shells. If Dd egg-producing snail and a dd sperm-producing snail mate what genotype(s) and phenotype(s) of offspring will result
The cross between Dd egg-snail and a dd s snail mate will result in snails with genotype 1/2 Dd:1/2 dd and phenotype all right-coiling.
What is a genotype?The genotype refers to the allele combinations that can be found for one or more loci in an individual.
The phenotype refers to how the genes and alleles interact to produce a physical trait in an organism.
In this case, one parent can produce two types of gametes (D and d), whereas the other parent can only produce d gametes.

What are three ways that the function of a root is helped by its structure
Answer:
Subsequently, question is, what are three ways that the function of a root is helped by its structure? A root's four major functions are 1) absorption of water and inorganic nutrients, 2) anchoring of the plant body to the ground, and supporting it, 3) storage of food and nutrients, 4) trans locating water and minerals to the stem.
Explanation:
In addition to absorbing water and nutrients, they also anchor and support the plant and store food.
What are roots?Roots are defined as a vascular plant's subterranean portion. Water and essential minerals are taken up by a plant's roots from the earth and sent to the stem. The plant's roots firmly anchor it to the earth. They first give a plant the anchor it needs to stay put. More significantly, a plant's roots are its life support system because they transport nutrients, water, and air up into the leaves.
The root hairs have a vast surface area, making them ideal for absorbing water from the soil. The absorption increases as surface area increases. There is a semi-permeable barrier on each root hair. Anchoring the plant, absorbing water and dissolving nutrients, transferring them to the shoot, storing nutrients, vegetative reproduction, and binding soil particles are just a few of the crucial roles that roots play in plants.
Thus, in addition to absorbing water and nutrients, they also anchor and support the plant and store food.

1: Explain why cellular respiration releases energy as an overall chemical reaction.
2:Explain why the amount of biomass and stored energy is lower at high trophic levels than it is at low trophic levels
Cellular respiration is the metabolic reaction inside the cell to convert chemical energy into ATP. Biomass is the total mass of organisms at a trophic level.
What is exothermic reaction?The type of reaction in which releases energy after its completion.
Cellular respiration releases energy because it is an exothermic process in which energy is released as a by-product of the reaction.Organisms are larger in size at higher trophic levels, but their smaller numbers result in less biomass.Thus, being exothermic in nature, cellular respiration releases energy and because of less numbers, there is less biomass at high trophic levels.

In a population of short, ground-dwelling animals, some offspring were produced that were approximately 1 cm taller than others in the population. This group was able to reach slightly higher vegetation than the rest of the population. When these animals grew up, they were able to produce more offspring than other animals in the population. This pattern, where the tallest animals were more likely to survive and reproduce, continued over several generations. Eventually, after many generations, all members of the population were at least 20 cm taller than animals of the original population had been. What does this illustrate?
A. Biological change does not apply to ground-dwelling animals. B. Slight differences between parents and offspring can eventually result in future generations that are very different from their ancestors. C. Only major differences between parents and offspring can result in future generations that are very different from their ancestors. D. Ground-dwelling animals would survive better if they evolve to be shorter.
Answer:
B. Slight differences between parents and offspring can eventually result in future generations that are very different from their ancestors.
Explanation:
Seemingly minor mutations that increase a species' ability to survive will likely be spread over many generations, and can eventually cause major differences between generations.

Vasoconstriction of the afferent arteriole and/or vasodilation of the efferent arteriole will cause a(n) __________ in glomerular filtration rate (GFR).
Afferent arteriolar vasoconstriction decreases blood flow into the glomerulus, which causes the glomerular-capillary blood pressure to decrease, leading to a(n) decrease in the net filtration pressure and a resultant decrease in the GFR.
What happens if the afferent arteriole is vasoconstriction?Constriction of the afferent arterioles has two inpact
it increases the vascular resistance which lessens renal blood flow (RBF), and it lowers the pressure downstream from the constriction, which lower the GFR.

How and why might the R0 value change over time during an outbreak? pls help
Answer:
Vaccinations
Explanation:
For example, if a disease has an R0 of 18, a person who has the disease will transmit it to an average of 18 other people. That replication will continue if no one has been vaccinated against the disease or is already immune to it in their community. So if you have (for example) a vaccination then you're less likely to get it, resulting in a lower R0
