In a population of cattle, the average body fat percentage is 10.5%. You select parents with an average body weight percentage of 20.8%. The offspring they produce have an average body weight percentage of 17.6%. Based on these data, what is the narrow-sense heritability of this trait
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

Are there any differences between what we need as humans and what animals need? If so, what?
Answer:
Animal society is mainly based on instincts or reflex behavior, whereas human society is based on reason or rational behavior. There are no rights and duties in animal society. Every animal lives upon his physical powers whereas human society has a wonderful system of law and order.
Animals usually live in the wild where they have to find there own food and hunt for it, where we as humans spend money on our food and it is all at the grocery store. There are more differences but this is one main difference.

Traditional antibiotics build immunity by exposing the memory cells of our body to inactive versions of viruses or bacteria.
True
False
Conventional antibiotics increase immunity by exposing our bodies' memory cells to dormant viruses or bacteria. So, the aforementioned is True.
What are Antibiotics?A particular class of antimicrobial agent that works against bacteria is an antibiotic. Antibiotic drugs are frequently used for the treatment and control of bacterial infections because they are the most effective type of effective antibacterial for doing so. Bacteria may be killed or have their growth suppressed.
Several types of bacterial infections are treated or prevented with the help of antibiotics. They either eradicate bacteria or stop them from proliferating and spreading.
Viral infections cannot be treated with antibiotics. This covers the typical cold, the flu, the majority of coughs, and sore throats. By introducing our bodies' immunological memory to latent viruses or bacteria, traditional antibiotics boost immunity.

gases and nutrients in

A. mitochondria
B. cytoplasm
C. nucleus
D. cell membrane
The cell membrane allows gases and nutrients in and out of the cell.
The correct answer is option D, the cell membrane. The cell membrane, also known as the plasma membrane, is a vital component of all cells. It serves as a selectively permeable barrier that separates the internal environment of the cell from its external surroundings. One of its crucial functions is to regulate the movement of substances in and out of the cell, including gases and nutrients.
The cell membrane is made up of a phospholipid bilayer embedded with various proteins. These proteins play a role in facilitating the transport of molecules across the membrane. There are two main types of transport across the cell membrane:
Passive Transport: This includes processes like diffusion and facilitated diffusion, where substances move from an area of higher concentration to an area of lower concentration. Small gases like oxygen and carbon dioxide can passively diffuse through the lipid bilayer of the membrane.
Active Transport: This involves the use of energy to move substances against their concentration gradient, from an area of lower concentration to an area of higher concentration. Nutrients and other molecules can be actively transported using protein pumps.
In both cases, the cell membrane is responsible for controlling what enters and exits the cell, maintaining an appropriate internal environment for cellular functions. This selective permeability ensures that essential gases like oxygen and nutrients can enter the cell while waste products can exit. Thus, the cell membrane is a crucial structure that enables the exchange of gases and nutrients required for cellular metabolism and survival.

The policy which would would increase the risk of a liquidity crisis is Banks
being required to store a smaller percentage of depositor funds in their
vaults.
Liquidity occurs when there is an increase in demand and decrease in
supply. Banks usually have a large percentage of depositor funds stored in
their vault to prevent these occurrence.
In situations whereby they store a smaller percentage of depositor funds in
their vaults , it will lead to a liquidity crisis as they won't be able to cater for

3. In 1981, a stray black cat with unusual curled-back ears was adopted by a family in California. Suppose you were the person who owned the first "curl" cat, and wanted to develop it into its own breed. How would you determine whether the allele for curled ears is dominant or recessive? Why does it make a difference for breeders whether an allele for a trait is dominant or recessive?
It is possible to determine whether the allele for curled ears is dominant or recessive by performing a test cross. It is fundamental for breeders because desired traits show differential patterns of inheritance.
In a diploid (2n) organism, a given gene locus exhibit two different variants or forms called 'alleles'.
An individual is homo-zygous when both alleles for a given gene locus are the same, while an individual is heterozygous when alleles are different.
In cases of complete dominance, the expression of the recessive allele is completely masked in heterozygous individuals.
A breeder is a professional who performs genetic crosses between different organisms in order to obtain offspring (eg., plants, animals, etc) with desired phenotypic features.
A test cross is a type of cross that breeders use to determine whether an allele is dominant or recessive (in this case, the allele for curled ears).
In a test cross, the organism that is a carrier of the unidentified allele is crossed with another organism that is believed to be homo-zygous for the recessive trait, and then the proportion of offspring is examined.

How does meiosis most benefit a species?
It decreases the number of chromosomes.
It increases genetic variation.
It increases the number of chromosomes.
It increases mutations.
Answer:
It increases genetic variation.
Explanation:
Meiosis does not decrease the number of chromosomes nor increase the number of them, it merely splits them.
While it could increase mutations, this might not necesarily be a good thing.
However, it does increase genetic variation, especially during the process where crossing over occurs. Increased genetic variation is beneficial for the population for many reasons like higher resistance to certain diseases. Increasing genetic variation also makes a species look unique from other members of the species.
