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.

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.

Phosphocreatine is a chemical compound that provides high energy to the skeletal muscles. One molecule of phosphocreatine produces one ATP molecule. Thus, option a is correct.

The phosphocreatine system is a way to generate ATP and energy in the body (muscles). During muscle contraction, the phosphocreatine yields a phosphate molecule that in turn produces ATP.

The phosphocreatine system provides quick and fast energy in the form of ATP molecules through the anaerobic system that does not require oxygen. It gives its phosphate group to ADP to produce ATP as,

ADP + phosphocreatine → ATP + Creatine

The ATP-PC system yields only one molecule per phosphocreatine at a very fast rate for the muscles to utilize when doing any exercise or physical activity that involves contraction and relaxation.

Therefore, phosphocreatine produces 1 ATP.

The correct graphical representation of the organization levels of a biological system is as follows:

The level of the biological system may be defined as the arrangement of structures that are usually characterized by relationships with things at higher levels that are being composed of things at the next lower level. A cell is the smallest level of organization for living things while the biosphere is the highest level of organization for living things.

A cell is the basic structural and functional unit of living organisms. The collection of cells gives rise to the formation of tissues which are combindly known as organs. Organs give rise to the organ system that completely formed a living entity.

Therefore, the correct graphical representation of the organization levels of a biological system is well represented above.

A place on the enzyme where the reaction occurs

A substrate can be defined as the reactant in a chemical reaction. A substrate is consumed during a chemical reaction and it is converted into product molecules.

A substrate can be defined as a molecule that an enzyme reacts with during a chemical reaction. The active site of an enzyme are the locations where weak bonds between the two substrate molecules can be formed, this place is loaded with a substrate molecule. An enzyme substrate complex is formed, and the enzyme's pressure on the substrate is responsible for the reaction and it become the planned reaction's result.

Some examples of substrate molecule include carbohydrates like glucose, starch act substrates for the enzymes such as salivary amylase, maltase. Amino acids, proteins act as substrate molecules for enzymes such as trypsin, chymotrypsin, etc.

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.

Answer:

the spotted parent has the genotype ss

Explanation:

we will use s as the letter when describing the spotted trait.

since spotted is recessive, that parents have to have two little s to have the trait. Since the child also has that, we know that they will have the genotype ss.  the child would have to get a little s from both parents, so the solid parent would have Ss, showing as solid, but still having the gene for spots.

Answer:

Photosynthesis removes carbon dioxide naturally

Explanation:

When trees or plants take CO2 out of the air and recycle it with oxygen

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.

Explanation:

The other two are positive aspects, and these two are true.

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.
