Prolactin hormone allows a woman to produce milk after she gives birth. Thus, the correct option is D.

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.

Complete question: PUNNETT SQUARE CROSSES

1. Set up and complete Punnett squares for these crosses (remember Y = yellow, y = blue):

a. YY and Yy

b. YY and yy

2. Answer these questions: a. What are the resulting phenotypes? b. Are there any blue kernels? c. How can you tell whether or not there are blue kernels?

3. Set up and complete a Punnett square for a cross of two of the F1 from Step 1 (above).

4. Answer these questions: a. What are the genotypes of the F2 generation? b. What are their phenotypes? c. Are there more or fewer blue kernels than in the F1 generation?

5. Identify the four possible gametes produced by the following individuals (S = smooth, s = wrinkled):

a. YY Ss

b. Yy Ss

Punnett squares are used to get the genotypic and phenotypic frequencies among the progeny produced from a cross. Punnett squares and answers below.

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

1/2 = 50% of the progeny is expected to be homozygous dominant, YY

1/2 = 50% of the progeny is expected to be heterozygous, Yy

   Phenotype

100% of the progeny is expected to be yellow.

b- Cross 2

Parentals)  YY   x    yy

Gametes) Y     Y     y    y

Punnett square)      Y        Y

                       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.  

3) Let us cross two heterozygous individuals from the F1

Parentals)  Yy   x    Yy

Gametes) Y    y     Y    y

Punnett square)     Y        y

                       Y    YY     Yy

                        y    Yy      yy

F1) Genotype

1/4 = 25% of the progeny is expected to be homozygous dominant, YY

1/2 = 50% of the progeny is expected to be heterozygous, Yy

1/4 = 25% of the progeny is expected to be homozygous recessive, yy    

   Phenotype

75% of the progeny is expected to be yellow.

25% of the progeny is expected to be blue.

4)

a. What are the genotypes of the F2 generation?

- 25% YY (homozygous dominant)

- 50% Yy (Heterozygous)

- 25% yy (Homozygous recessive)

b. What are their phenotypes?

- 75% yellow kernels

- 25% blue kernels

c. Are there more or fewer blue kernels than in the F1 generation?

More. Blue kernels appeared in the F2.

5. Assuming independent genes, the resulting gametes after meiosis are as follows

                        Gametes

a. YY Ss   ⇒   YS, YS, Ys, Ys

b. Yy Ss  ⇒     YS, Ys, yS, ys

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.

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.

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.

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.

Greater force of contraction, volume of blood ejected, and cardiac output result in aerobically trained individuals with greater stroke volume compared to untrained individuals

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

The diagram below (attached image) represents two cells, X and Y.

Which statement is correct concerning the structure labeled A?

A) It is involved in cell communication in cell X but not in cell y.

B) It represents a cell wall in cell X and the cell membrane in cell y.

C) It prevents the absorption of CO2 in cell x and O2 and cell y.

D) It aids in the removal of metabolic waste in both cell X and Y ​

Cell membrane accomplishes several functions, among them, the removal of cell wastes. Option D. It aids in the removal of metabolic waste in both cell X and Y.

The cell membrane is a barrier that surrounds the cell content and isolates it from the extracellular space. It is composed of two lipidic layers, proteins, and glucans incrusted in between.

The cell membrane accomplishes many different functions. Among them, we can mention,

Substances interchange

⇒  Passive transport → Simple diffusion → through lipids

                                     → Facilitated diffusion → Assisted by channel  

                                        proteins

                                     → Does not need energy

                                    → Depends on the molecule size, the concentration                      

                                       at each side of the membrane, and the charge of      

                                       the ions.

                                      → Occurs in favor of the electrochemical gradient

⇒ Active transport → It does the energy to occur

                                → Mediated by carrier proteins

                                → Transport big-sized molecules

                                → Against the electrochemical gradient

⇒ Endocytosis/Exocytosis → Active transport mediated by vesicles.  

In the exposed example X cell represents an animal cell, and Y cell is a plant cell.

Both the animal and plant cells are eukaryotic. They carry their genetic material in the nucleus and mitochondria. Organelles are located in the cytosol, and both of them are surrounded by a protector cell membrane.
