Heritability in the narrow sense -h²- refers to the proportion of the phenotypic variability that is influenced by genetic factors. In the exposed example, the narrow-sense heritability of this trait is h² = 0.689 ≅ 0.7
-----------------------------
Before answering the question, let us first review a few concepts.
The selection differential, SD, is calculated by getting the difference between the mean value of the desired trait in the population (X₀) and the mean value of the same trait expressed by parents, (Xs). So,SD = Xs - X₀
Heritability in the narrow sense -h²- is the measure of the genetic component to which additive genetic variance contributes.It referes to the proportion of the phenotypic variability that is influenced by genetic factors.
The heritability might be used to determine how the population will respond to the selection done, R.
h² = R/SD
The response to selection (R) refers to the metric value gained from the cross between the selected parents. R can be calculated by multiplying the heritability h² with the selection differential, SD.R = h²SD
R also equals the difference between the new generation phenotypic value (X₁) and the original population phenotypic value (X₀),
R = X₁ - X₀
Now that we know these concepts and how to calculate them, we can solve the proposed problem.
Available data:
Population average body fat ⇒ 10.5% ⇒ X₀ Selected parents average body weight ⇒ 20.8% ⇒ XsOffspring average body weight ⇒ 17.6% ⇒ X₁We ned to get the narrow-sense heritability of this trait, h².
h² = R/SD
R = X₁ - X₀ = 17.6% - 10.5% = 7.1%SD = Xs - X₀ = 20.8% - 10.5% = 10.3%
h² = R/SD = 7.1% / 10.3% = 0.689 ≅ 0.7
The narrow-sense heritability of this trait is h² = 0.689 ≅ 0.7

Explain how each of the following could lead to the reemergence of malaria in the United States: (a) global warming, (b) increased travel of individuals from endemic regions to the United States, (c) increased immigration of individuals from endemic regions to the United States, and (d) laws protecting wetlands.
Answer:
(b) increased travel of individuals from endemic regions to the United States,
The possible reason that lead to the reemergence of malaria in the United States is increased travel of individuals from endemic regions to the United States. The correct option is b.
What is malaria?Malaria is a potentially fatal disease caused by a parasite that infects a specific type of mosquito that feeds on humans. Malaria typically causes severe illness, including high fevers, shaking chills, and flu-like symptoms.
Malaria is typically transmitted through the bite of an infective female Anopheles mosquito. Only Anopheles mosquitos can transmit malaria, and they must have previously been infected through a blood meal taken from an infected person.
It has been determined that mosquitoes become infectious more quickly, resulting in increased malaria transmission and increased travel from endemic regions to the United States.
Thus, the correct option is b.

When a cross between 2 contrasting parents produces new phenotype, different from
either parents, we can conclude that that there is which of the following?
When a cross between 2 contrasting parents produces a new phenotype, it is known as incomplete dominance. In diploid (2n) organisms, individuals receive one allele or gene variant from each parent.
Heterozygous individuals carry different alleles for the same gene locus.
Incomplete dominance occurs when both alleles are expressed in heterozygous organisms.
The phenotype in cases of incomplete dominance is a mixture of the phenotype observed in both parents.

Answer: These stem cells are manipulated to specialize into specific types of cells, such as heart muscle cells, blood cells or nerve cells. The specialized cells can then be implanted into a person. For example, if the person has heart disease, the cells could be injected into the heart muscle.
Explanation: Describe the three methods for harvesting stem cells, for each method, explain the benefits of the method and the ethical concerns related to the method
Stem cells are specialized cells that can proliferate into many types of cells lineages. Umbilical cord blood collection, bone marrow harvesting and dental pulp collection are the methods.
What are stem cells harvest methods?Stem cells can be collected from the blood and the tissues of the umbilical cord of the baby born and is an easy method that collects the cells from the umbilical cord and the placenta for future use.
The cells and the tissues are chopped and kept in the low temperatures that include the Mesenchymal stem cells in it. They are beneficial as they can treat cancers, anaemia etc. There are not many ethical issues related to umbilical cord use.
Stem cells can be derived from the bone marrow as this is the site where they originate from. The method uses the removal of the bone marrow from the pelvic bones and subjects them to the removal of the stem cells from the blood.
Stem cells from the bone marrow are used for the replacement of damaged cells. The use of the bone marrow and using human lives is the ethical issue concerned with bone marrow based stem cells.
The dental pulp collection method of the stem cells uses the method of deriving cells from the teeth region and are a source of the bone and the mesenchymal cells.
DPSCs can be used for cell banking and are the method that has no ethical concerns. It is simple can be done in dental routines.
Therefore, umbilical cord, dental pulp and bone marrow are the stem cells collection methods.

A runner expends an average of 4 kcal per minute during a two hour run. She want to eat a meal of
50% energy from carbohydrate, 25% of energy from protein and 25% of energy from fat, how
much protein would their meal have to contain, in order to replenish their expended energy?
Given what we know about nutrition, we can confirm that the runner's meal would have to contain 30 grams of protein.
The runner in question wishes to complete a two-hour run while expending 4kcal or calories per minute, for a total of 480kcal. Furthermore, the runner wishes for only 25% (120kcal) of this energy to come from a source of protein.
Since every gram of protein adds 4 calories of energy to the meal, and we have to account for 120 calories, the runner will have to consume 30 grams of protein to achieve the desired results.

Could there be winds without differential heating? Using evidence from Unit 5 explain what differential heating is and whether this effects the earth’s global wind patterns.
HELPPP PLEASE SITE EVIDENCE (WILL MARK BRAINLIEST)!!!!!!!!
Differential heating is responsible for the wind patterns across the globe.
Differential heating is defined as the difference in heating of air on the land versus water. Sea breezes occur when land heats up faster than water which rises and creates a low pressure system. The high pressure air from the sea influxes is responsible for the creation of a sea breeze.
Unequal heating of the Earth's surface is responsible for the formation of large global wind patterns. Warm air rises at the equator and moves toward the poles while on the other hand, the cooler air rises at the poles and moves back toward the equator so in this way the earth’s global wind patterns occurs so we can say that differential heating is responsible for the wind patterns across the globe.
