Answer:

If you have elevated carbon dioxide in the blood, the body sends a signal to the lungs to breathe faster to eliminate the carbon dioxide build-up, thus causing a faster breathing rate.

Explanation:

raised carbon dioxide triggers an increase in respiratory rate, which decreases the amount of carbon dioxide, and the respiratory rate falls again.

For a person to develop Huntington's disease, he must be homozygous (HH) or heterozygous (Hh) for the dominant allele.

Huntington’s disease is a type of defective dominant disease. This means that any person having 1 or 2 defective dominant genes, have the disorder.  But, if a person has 2 recessive genes, they are normal.

ATP can be hydrolyzed to ADP and Pi by the addition of water, releasing energy. ADP can be "recharged" to form ATP by adding energy, combining with Pi in a process that releases a water molecule.

As energy is released, they form ATPs, binding phosphate to ADP. So the energy is in ATP. The process of binding phosphate to ADP is called oxidative phosphorylation.

There are three common energy-producing processes for making ATP:

The rainforest is one of the most diverse biomes. Options A and D. Experience some of the most fertile soil in the world.  Are numerous and in constant competition for sunlight.

The tropical rainforest is a biome is located near the equator, where precipitations are abundant and the average temperature is elevated most of the year.

As a result of the climatic conditions, this biome gives shelter to a huge number of living organisms. The canopy structure provides many refuges for plants and animals and is an important source of food. It also favors interactions between species.

There are different plant species, such as epiphytes, lianas, stranglers, aerial-rooted pants, and tabular-rooted plants, among other vegetation forms.

Fanerophic species dominate this biome. Evergreen tall trees might reach up to 50 meters in height. They develop dense foliation and branches, becoming a refuge and source of food for many species.

Vegetation does not need to develop strategies for surviving the dry season. Instead, they need to develop strategies for competing for light and nutrients.

Since vegetation is very dense, woody species grow in height looking to get greater sun radiation. Competition for sunlight is quite significant, generating different strata canopy at varying levels in the forest.

Abundant vegetation and other factors such as temperature, precipitation, and natural cycles create one of the most fertile soils favoring the growth and development of many species.

According to this framework, the correct options are A and D.  Experience some of the most fertile soil in the world. Are numerous and in constant competition for sunlight.

Answer: It will be a homologous

Explanation:

The enzyme’s shape changes as it binds to its substrate because enzymes are highly specific, the main reason for enzyme’s shape changes as it binds to its substrate is temperature, pH and time.

Is due to the fact that the enzyme's active site has a complementary format to its substrate, promoting a contract, like a key that fits perfectly in a given fixation.

Substrate is the reagent on which an enzyme acts. When an enzyme binds to its substrate, the enzyme-substrate complex is formed. This binding takes place in a specific region, called the active site.

One exemple of an enzyme changing it's shape to binds to a substrate is pepsine. Pepsine changes it's shape to bind to proteins in the stomach and break them down into smaller peptides.

Based on the definition of supplementary angles, the angles are: 2° and 178°.

Angles that are supplementary have a sum that equals 180 degrees.

Let the measure of the supplement be x.

The other angle would be: (x + 176)

Therefore, we would have:

x + (x + 176) = 180

2x + 176 = 180

2x = 180 - 176

2x = 4

x = 2

One of the angles is, 2°

Second angle = x + 176 = 2 + 176 = 178°

The elevated level of HDL cholesterol would increase the risk for atherosclerosis, which could eventually lead to heart attack or stroke.

The blood flow is obstructed by a buildup of cholesterol plaque in the artery walls. The artery may suddenly become blocked by a clot when plaques burst. Atherosclerosis frequently goes unnoticed until a plaque bursts or the buildup becomes severe enough to obstruct blood flow. Exercise and a nutritious diet may be beneficial. Medication, artery-clearing surgery, and other forms of treatment are available. A CT scan of the heart called a "coronary calcium scan" quantifies the calcium content of the coronary artery walls. Atherosclerosis or coronary heart disease are indicated by calcifications, a buildup of calcium. Hospitals or medical imaging centers may do a coronary calcium scan.

A test cross must be performed to ascertain this plant's genotype. Yellow and green peas are the anticipated phenotypes of the progeny.

To ascertain whether a progeny is homozygous or heterozygous for a given trait, an F1 progeny is crossed with a double (homozygous) recessive parental progeny (green pea). This is referred to as a test cross.

All of the hybrid's offspring will exhibit the dominant (yellow) phenotype if the mother is homozygous (YY) dominant.

Mother  yellow pea (YY)  x   green pea (yy)   - P generation

                            Y                            y             - Gamete

                          Yy (yellow) , Yy (yellow)         -F1 generation

If the mother is heterozygous dominant(Yy), then half of the offspring will exhibit the dominant phenotype and the other half will exhibit the recessive phenotype and the ratio should be 1:1.

Mother yellow pea (Yy)   x    green pea (yy)   -P generation

                           Y, y                            y            - Gamete

                           Yy (yellow) , yy (green)           -F1 generation

Therefore, it is concluded from the above explanation that we have to perform a test-cross to know the genotype of the pea plant.
