A female fish may lay thousands of eggs at once. The additional statement about the fish which is most useful for explaining that the fish species can evolve by natural selection is that the fish eggs will develop into embryos only if they are fertilized by the sperm from the male fish. Thus, the correct option is D.
What is Natural selection?Natural selection can be defined as the differential survival and reproduction of the individual species due to the differences in phenotype of the organism. Natural selection is a key mechanism of evolution, the change in the heritable traits or characteristics of a population which take place over the period of several generations.

Increasing the alveolar ventilation rate will Group of answer choices increase the partial pressure of oxygen in the alveoli. decrease the rate of oxygen diffusion from the alveoli to the blood. increase the partial pressure of carbon dioxide in the alveoli. decrease the rate of carbon dioxide diffusion from the blood to the alveoli. have no effect on either the partial pressure or diffusion rate of gases.
Answer:
Increasing the alveolar ventilation rate will increase the partial pressure of oxygen in the alveoli.
Explanation:
Alveolar Ventilation rate is the rate of air flow in the alveoli of the lung during normal breathing. It is measured in milliliters of air per minute (mL/min). The alveolar ventilation rate is an important factor in determining the concentrations (partial pressures) of oxygen and carbon dioxide in the functioning alveoli.
A high rate of alveolar ventilation, would result in a rapid influx of oxygen-rich air and efflux carbon dioxide-filled air from the alveoli. This ultimately results in an increase in the concentration of oxygen and a decrease in the concentration of carbon dioxide within the alveoli.
Effects of alveolar ventilation on partial pressures of alveolar carbon dioxide and oxygen (PACO₂ and PAO₂)
If the alveolar ventilation rate is increased (and carbon dioxide production is unchanged), then the partial pressure of carbon dioxide in the alveoli, PACO₂ will decrease.
If the alveolar ventilation rate increases, then the partial pressure of oxygen in the alveoli, PAO₂ will increase.

At one time, Chondrichthyes were thought to have diverged from other vertebrates before the evolution of bone. Now we have concluded that the Chondrichthyes diverged after the evolution of bone had started. What does this change demonstrate about the evolution of fishes
Answer:
The correct answer would be - Characteristics can be lost in evolution.
Explanation:
The new evidence helps in developing a new hypothesis. In this case, new evidence proved that the Chondrichthyes diverged after the evolution of bone had started instead of before the evolution started. This process called atavism where an ancestral genetic trait reappears after having lost. This leads to loss of the traits in the evolution
This can take place by knocking the mutation out to overriding the gene by the old gene or overriding the new trait by the old trait during the evolution period.
At one time, Chondrichthyes were thought to have diverged from other vertebrates before the evolution of bone. Now we have concluded that the Chondrichthyes diverged after the evolution of bone had started might be their characteristics lost in evolution according to atavism.
What is atavism?
Recurrence in an organism of a trait or character typical of an ancestral form and usually due to genetic recombination. This leads to the loss of the traits in the evolution.
Hence, Chondrichthyes diverged after the evolution of bone had started might be their characteristics lost in evolution according to atavism.

what is HIV in full
Answer:
Human Immunodeficiency viruses
HIV Overview
HIV (human immunodeficiency virus) is a virus that attacks the body’s immune system. If HIV is not treated, it can lead to AIDS (acquired immunodeficiency syndrome).
There is currently no effective cure. Once people get HIV, they have it for life.
But with proper medical care, HIV can be controlled. People with HIV who get effective HIV treatment can live long, healthy lives and protect their partners.
History of HIV
HIV infection in humans came from a type of chimpanzee in Central Africa.
The chimpanzee version of the virus (called simian immunodeficiency virus, or SIV) was probably passed to humans when humans hunted these chimpanzees for meat and came in contact with their infected blood.
Studies show that HIV may have jumped from chimpanzees to humans as far back as the late 1800s.
Over decades, HIV slowly spread across Africa and later into other parts of the world. We know that the virus has existed in the United States since at least the mid to late 1970s.
To learn more about the history of HIV in the United States and CDC’s response to the epidemic, see CDC’s HIV and AIDS Timeline.
How do I know if I have HIV?
The only way to know for sure whether you have HIV is to get tested. Knowing your HIV status helps you make healthy decisions to prevent getting or transmitting HIV.
Are there symptoms?
Graphic listing symptoms of HIV: Fever,HIV Symptoms and Testing, Chills, Rash, Night sweats, Muscle aches, Sore throat, Fatigue, Swollen lymph nodes, and Mouth ulcers.
Some people have flu-like symptoms within 2 to 4 weeks after infection (called acute HIV infection). These symptoms may last for a few days or several weeks. Possible symptoms include
Fever,
Chills,
Rash,
Night sweats,
Muscle aches,
Sore throat,
Fatigue,
Swollen lymph nodes, and
Mouth ulcers.
But some people may not feel sick during acute HIV infection. These symptoms don’t mean you have HIV. Other illnesses can cause these same symptoms.
See a health care provider if you have these symptoms and think you may have been exposed to HIV. Getting tested for HIV is the only way to know for sure.
What are the stages of HIV?
When people with HIV don’t get treatment, they typically progress through three stages. But HIV medicine can slow or prevent progression of the disease. With the advancements in treatment, progression to Stage 3 is less common today than in the early days of HIV.
Stage 1: Acute HIV Infection
Stage 1: Acute HIV Infection
People have a large amount of HIV in their blood. They are very contagious.
Some people have flu-like symptoms. This is the body’s natural response to infection.
But some people may not feel sick right away or at all.
If you have flu-like symptoms and think you may have been exposed to HIV, seek medical care and ask for a test to diagnose acute infection.
Only antigen/antibody tests or nucleic acid tests (NATs) can diagnose acute infection.
Stage 2: Chronic HIV Infection
Stage 2: Chronic HIV Infection
This stage is also called asymptomatic HIV infection or clinical latency.
HIV is still active but reproduces at very low levels.
People may not have any symptoms or get sick during this phase.
Without taking HIV medicine, this period may last a decade or longer, but some may progress faster.
People can transmit HIV in this phase.
At the end of this phase, the amount of HIV in the blood (called viral load) goes up and the CD4 cell count goes down. The person may have symptoms as the virus levels increase in the body, and the person moves into Stage 3.
People who take HIV medicine as prescribed may never move into Stage 3.
Stage 3: Acquired Immunodeficiency Syndrome (AIDS)
Stage 3: Acquired Immunodeficiency Syndrome (AIDS)
People with AIDS have such badly damaged immune systems that they get an increasing number of severe illnesses, called opportunistic infections.
People receive an AIDS diagnosis when their CD4 cell count drops below 200 cells/mm, or if they develop certain opportunistic infections.
People with AIDS can have a high viral load and be very infectious.
Without treatment, people with AIDS typically survive about three years.

Why do these sisters have different traits? Use these words in your response (protein, molecule, structure, trait, variation) describing what would determine these traits at the molecular scale.
Answer:
[Protein, Molecule, Structure, Trait, Variation]
Each offspring receives two copies or variations of each gene, one from their mother and one from their father. Each offspring can inherit a different combination of gene versions, so siblings can have different traits from each other and from their parents. The girl on the right has straight hair, whereas the girl on her left, has curlier hair. A gene code for a specific protein that's involved in a traits expression. In the structure of a cell, the proteins do much of the chemical work inside the cell, so they largely determine the traits and whose they are. Another thing to remember is genes are also made up of molecules. Thin strands twisted around each other like a spiral staircase.

The differences that occur at the molecular level or in the genes, will result in changes in the proteins which the genes code for bringing about variation in traits.
What is variation?Variation refers to the changes that occur between individuals of the same species due to environmental or genetic factors.
The basis for variation is differences that occur at the molecular level.
The genes are regions of the DNA which code for a particular trait.
The DNA is composed of chains of polynucleotide molecules.
When differences occur at the molecular level or in the genes, the proteins which the genes code for will have differences in structure.
Thus, the individuals will show variation as in the case of the two sisters who show variation in height and hair structure.

Using established recombinant DNA technology, you insert a gene from a human immune cell into a bacterium. The bacterium expresses the protein corresponding to the inserted DNA. To your disappointment, you discover that the protein produced is useless and is found to contain many more amino acids than does the protein made by eukaryotic cells. Assuming that there is no mutation in the human gene, what is a reasonable explanation for why this happened
The group of choices associated with the question is -
The inserted gene does not have a start codon.
The inserted gene does not have a stop codon.
The inserted gene is not present in bacteria.
The inserted gene contained introns.
None of the above.
Answer:
The correct answer is - The inserted gene contained introns.
Explanation:
In the given case says that one gene inserted from human to bacteria that produces a protein with more amino acids than humans. In eukaryotic organisms, there is a process that removes the unwanted mRNA part during transcription and joins exons together, called splicing to form functional mRNA.
In this case. splicing does not take place as bacteria is a prokaryotic organism and splicing is exclusive to eukaryotic organisms like humans.
So introns are also translated into protein in bacteria due to lack of splicing genes.
