Which statement is true about oxygen and nutrient levels of rivers? TIMED TEST

Your answer:

Fast moving mountain streams which flow over rocks and waterfalls are high in oxygen due to the amount of surface area of the water that is exposed to the air.


Fast moving mountain streams are high in nutrients. Organisms have adaptations to hold on in fast moving water, resulting in a large diversity organism.


Slow moving flood plain rivers are high in oxygen due to the amount of surface area of the water that is exposed to the air.


Slow moving flood plain rivers are low in nutrients. These rivers move too slow for plant growth and other organisms to survive.

All organisms utilize adenosine triphosphate (ATP) as their major source of energy. The molecules
of ATP and ADP (adenosine diphosphate) + P: (inorganic phosphate) form a cycle to allow for a
constant source of energy-rich ATP molecules.
Which of the following MOST accurately describes the role of ATP as a source of energy?
O ATP absorbs energy as it is converted into ADP + Pi.
ADP + P; release energy as they are converted into ATP.
O When ATP is converted into ADP + Pi , energy is released and used by the cell.
O When ADP + Pi are converted into ATP, energy is released and used by the cell.

Answers

Answer:

When ATP is converted into ADP + P energy is released and used by the cell.

Explanation: ATP contains energy, when a certain part breaks off it converts into ADP and releases energy for the cell tp use.

When ATP is converted into ADP + Pi , energy is released and used by the cell is the most accurately describes the role of ATP as a source of energy.

What is ATP?

An organic substance called adenosine triphosphate (ATP) gives energy to a variety of biological functions in living cells, including muscular contraction, nerve impulse transmission, condensate dissolving, and chemical synthesis.

ATP is frequently referred to as the "molecular unit of currency" of intracellular energy transfer and is present in all known forms of life. It either transforms into adenosine monophosphate (AMP) or adenosine diphosphate (ADP) when absorbed in metabolic activities (AMP).

ATP is replenished by other processes. Every day, the human body recycles the equivalent amount of ATP to its own body weight. Additionally, it serves as a coenzyme and a precursor to DNA and RNA.

Therefore, When ATP is converted into ADP + Pi , energy is released and used by the cell is the most accurately describes the role of ATP as a source of energy.

Use hydrogen bonding to explain how the unique properties of water you observed emerge.

Answers

Water molecules are polar, so they form hydrogen bonds. This gives water unique properties, such as a relatively high boiling point, high specific heat, cohesion, adhesion and density.

Due to the existence of hydrogen bonding between the hydrogen atom and an oxygen atom of a water molecule, it shows the following unique properties.

It is polar in nature.It has a high heat of vaporization and high specific heat.Its solid form is less dense as compared to its liquid form.It illustrates other properties like cohesion and adhesion.It acts as a universal solvent.

How the charges are distributed in a water molecule?

The distribution of charge is determined by the fact that the oxygen atom attracts electrons a bit more strongly than the hydrogen atom. This is due to the unequal sharing of electrons between the two different atoms.

This unequal sharing of electrons is responsible for obtaining a slight negative charge near the oxygen atom, while a slight positive charge near the hydrogen atom.

Therefore, it is well described above.

O D. Higher land temperatures in the tropics

Answers

Answer:

Higher ocean temperatures in the tropics

Explanation:

apex :)

Higher ocean temperatures in the tropics are linked to increased hurricane strength. Therefore, option (C) is correct.

What is hurricane strength?

Hurricane strength is a measure of the intensity of a tropical cyclone, which is a rotating storm system that forms over warm ocean waters in the tropics. The strength of a hurricane is measured using the Saffir-Simpson Hurricane Wind Scale, which ranks hurricanes from Category 1 (weakest) to Category 5 (strongest) based on their sustained wind speeds.

Hurricanes can cause significant damage due to their strong winds, heavy rainfall, storm surges, and flooding. The strength of a hurricane is influenced by a variety of factors, including warm ocean temperatures, low wind shear, and high humidity. As global temperatures continue to rise due to climate change, it is expected that hurricanes will become more frequent and more intense, which could have significant impacts on coastal communities and infrastructure.

Refer to the family pedigree shown here. In generation I, one parent is affected by the gene mutation and one parent isn't. In generation II, all three children are affected by the gene mutation. What can you conclude about this gene mutation?

Answers

Answer:

What can be concluded about this genetic mutation is that it is inherited as a dominant trait.

Explanation:

In the case that one of the parents has a mutation whose inheritance pattern is dominant —which is rare— all the descendants will have the same mutation, since this gene will necessarily be expressed.

A dominant allele is one whose presence produces the phenotypic expression of the characteristic it determines. When the mutation is dominant, it will always be expressed in the descendants.

Hungtinton's disease and achondroplasia are examples of mutations with an autosomal dominant inheritance pattern.

Answer:

Occurrence of mud slides after heavy rains.

Explanation:

Soil erosion is defined as the removal of top soil from the land and it affects the fertility of the soil. It is also known as soil degradation.

Soil erosion has both short-term and long-term damage. Short-term damage of erosion includes the occurrence of mudslides after heavy rains which is called landslide. It is a short-term damage because landslides took long-duration to happen and when happened it can be shortly recovered using machines.

Hence, the correct answer is "the Occurrence of mudslides after heavy rains."
