Answer:

Two strands.

Explanation:

Answer:

2 strands

Explanation:

DNA is a double-stranded helix. During replication, the helix is broken apart and DNA polymerase adds new nucleotides to both strands. This results in the creation of new DNA. DNA will always have 2 strands.

Answer:

C. Nitrogen

Explanation:

this is because it is a nitrogen cycle

Answer:

As latitude and altitude increase, biomes and vegetation change. Trees of tropical rainforests usually grow closer to the equator, while mosses and lichen of the tundra grow closer to the poles.

Latitude determines the amount of sunlight received. The amount of sunlight and the amount of moisture received determines the ecosystem or biome. Biomes are partly determined by altitude. More precisely, biomes are mainly determined by temperature and precipitation, and the altitude can affect both temperature and precipitation. The temperature drops as the altitude increases. This would alter the structure and composition of our biome.

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 molecular data are not found here but rabbits and whales are linked with the dogs and pigs in a cladogram due to evolutionary relationships.

A cladogram is a graphical representation used to evidence the relationships between organisms due to a common evolutionary origin.

A cladogram is composed of a root that represents the common ancestor of the group and nodes where taxonomic groups diverge.

Cladograms based on molecular data use the homology level of nucleotide sequences of the genome to determine evolutionary relationships among individuals of different species.

In conclusion, rabbits and whales are linked with dogs and pigs in a cladogram due to evolutionary relationships.

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.

The idea that correctly states a relationship between the practice of conserving energy and the effect that it has on people's health is: Energy conservation promotes less air conditioner use and warmer homes (option B).

To conserve means to use judiciously or wisely, therefore, energy conservation refers to the effort made to reduce the consumption of energy by using less of an energy service.

The conservation of energy helps to reduce workload on mechanical devices such as air conditioner, cooker etc.

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°

Answer: The mutation gene codes for a protein that causes a new trait.

Explanation:

Answer:

jey que tal

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.
