The belief of Kiesha is that she was treated unfairly, her bloodstream likely contains high levels of cortisol.
What is the function of Cortisol?Cortisol is an essential hormone that plays a major role in regulating the body's stress, controlling body fat, activating anti-inflammatory pathways, and functions significantly in metabolism.
The expectation of promotion but did not get it causes some anxiety, stress, and loss of interest to Kiesha. As a result of this, the stress regulating hormone cortisol increases in the bloodstream to control the significant effect of stress on the body.
Therefore, it is well described above.

Moving molecules from low to high
concentration requires energy.
This is the opposite of diffusion.
What is this process called?
Answer:
Active transport
Explanation:
Diffusion is when particles (like perfume) spread out everywhere from an area where there is a lot of it to where there is a little to none of it. Active transport is the opposite. A cell for example would use it's own energy to absorb nutrients when it already has quite a lot. Naturally diffusion would make the particles or nutrients go out of the cell because there is a lot of it inside the cell not outside, so active transport is used to absorb as much as the cell can from around it, even when it is full.

Personal boats and watercraft do not contribute to ocean pollution. t/f
Answer and Explanation:
FALSE
Personal boats and watercraft DO contribute to ocean pollution.
Most water vehicles need fuel to be powered and go through the water. This fuel can sometimes go into the water, polluting the surrounding area.
Watercraft that don't use fuel, but instead are man-powered, can still contribute to ocean pollution. People can bring items such as soda cans, beer bottles, fishing equipment, etc., and any of these items tend to be discarded into the water, leading to pollution and degradation of the ecosystem, harming any wildlife that lives there.

7. Identify 3 adaptations that result in aerobically trained individuals having greater SV compared to
untrained individuals (I just need 3 adaptations listed). Please and thank you for your help in advance
Greater force of contraction, volume of blood ejected, and cardiac output result in aerobically trained individuals with greater stroke volume compared to untrained individuals
What increases stroke volume?A greater force of contraction consequently increases the volume of blood ejected with each systole (Systolic Volume). Increasing the stroke volume also increases, as a consequence, the cardiac output (CO = VS x HR).
With this information, we can conclude that greater force of contraction, volume of blood ejected, and cardiac output result in aerobically trained individuals with greater stroke volume compared to untrained individuals

Punnett squares are used to get the genotypic and phenotypic frequencies among the progeny produced from a cross. Punnett squares and answers below.
What is a punnett square?The Punnett square is a graphic representation that shows the different types of gamete combinations according to the alleles involved in a cross.
Punnett square shows the probabilities of getting offspring with different genotypes and their consequent phenotypes.
In the exposed example,
Diallelic genes that codes for color
Y = yellow ⇒ dominant allele
y = blue ⇒ recessive allele
We will assume complete dominance, meaning that genotypes with at least one dominant allele will express yellow.
1)
a- Cross 1
Parentals) YY x Yy
Gametes) Y Y Y y
Punnett square) Y Y
Y YY YY
y Yy Yy
F1) Genotype

y Yy Yy
y Yy Yy
F1) Genotype
100% of the progeny is expected to be heterozygous, Yy
Phenotype
100% of the progeny is expected to be yellow.
2)
a. What are the resulting phenotypes? Only yellow kernels
b. Are there any blue kernels? No
c. How can you tell whether or not there are blue kernels?
Blue is the recessive phenotype for kernels. Assuming complete dominance, since all genotypes are expected to carry at least one dominant allele, all the F1 kernels are yellow.

5. Draw conclusions: Natural selection is the process by which favorable traits tend to increase in frequency over time. How does this experiment illustrate natural selection
Natural selection is usually defined as the process by which forms of life having traits that better enable them to adapt to specific environmental pressures, as predators, changes in climate, or competition for food of mates, will tend to survive and reproduce in greater number than others of their kind, thus ensuring the perpetuation of those favorable traits in succeeding generations. Charles Darwin and Alfred Wallace developed the theory of evolution by natural selection and jointly presented papers on the subject in 1858. It is based on the finding that some distinctions between people in a group can be passed down across generations. Darwinism, or Darwin's theory, is a theory of evolution created by Charles Darwin stating that all life forms arise, change and develop from a process of natural selection. Natural selection is the process of changes in evolution due to the survival of certain individuals in a species. It is one of the most important parts of the theory of evolution. Darwin's idea provided a straightforward yet persuasive explanation for the diversity of species on Earth. Because various locations have distinct circumstances and survival possibilities, natural selection selects the organisms that are best adapted to that particular environment.

What was the problem with this genetic engineering solution
The potential for greater economic disparity and higher human misery, as well as the potential for extensive eugenics programs and dictatorial control over human life, are among the social and political concerns of genetic engineering. In certain situations, moral danger overrides technological risk without a doubt.
What is genetic engineering?Genetic engineering, often known as genetic alteration, is a technique that modifies an organism's DNA using technology developed in labs. This could entail altering a single base pair (A-T or C-G), erasing a section of DNA, or incorporating new DNA.
Millions of workers will be out of work in a few years if multinational businesses decide to replace the national products of Third World nations with their own biotechnology compounds. And the unintended result is guaranteed, not possible, or likely if governments decide to create racial programs and monitoring systems based on genetic engineering advances. The risk is not that the decision-makers underestimated the effects of their decisions, but rather that they act in an unethical manner.

Prolactin hormone allows a woman to produce milk after she gives birth. Thus, the correct option is D.
What is lactation?Lactation is the process of producing and releasing milk from the mammary glands in breasts. Lactation begins in pregnancy when hormonal changes signal the mammary glands to make milk in preparation for the birth of baby.
It’s also possible to induce lactation without a pregnancy using the same hormones that your body makes during pregnancy. Lactation ends once your body stops producing milk.
Milk ducts increase in size and number when levels of estrogen and progesterone rise. The result is a fuller breast. The mammary glands start to get ready to produce milk.
