Identify the phrase that best describes a transfer of energy between the hydrosphere and the atmosphere
HACTEHA [7]

Answer;

-Condensation and evaporation

Explanation;

-The atmosphere and hydrosphere are the two essential parts of the climate system. This is because they are able to absorb and store thermal energy, thus they act as heat sinks, and also by absorbing the energy and storing it, it creates a big impact on our atmosphere. Energy transfer by the atmosphere regulates the temperature of the earth.

-Once received by radiation or convection thermal energy is distributed through the atmosphere and the hydrosphere by convection and conduction. This is what creates a climate.

Nesterboy [21]

Answer:

(E) None of the above

Explanation:

All of the answers contribute to the high fidelity of DNA synthesis.

Accuracy of the DNA replication is achieved thanks to various mechanisms such as:

  • DNA polymerase activity (high processivity)-ability of the enzyme to copy long stretches of DNA
  • DNA polymerase proofreading-ability to recognize its own mistakes and fix them
  • Cell's surveillance-cell monitors its DNA status, checks for the damage

What is the role of your kidneys in compensating for low levels of oxygen
TEA [102]

Explanation:

When there are low oxygen levels in blood, the blood pH tends to lower. This is because there is an increased level of carbon dioxide in the blood that is converted to carbonic acid by carbonic anhydrase. When carbon acid dissociates, into H⁺ and HCO₃⁻ . The H⁺ influences the increase in acidity of the blood.   The kidneys will excrete most of the H⁺ and retain most of the HCO₃⁻ to help maintain the right blood pH. However, most of blood pH homeostasis is maintained largely by the lungs.

How does carbon dioxide concentration affect photosynthesis rate?
DiKsa [7]
Increasing the concentration of carbon dioxide increases the rate of photosynthesis, as there is a greater supply of it that can be used. Of course, you can only add so much carbon dioxide before the plant can’t perform photosynthesis at an any faster rate. Increased carbon dioxide concentration will increase the rate of photosynthesis until it is no longer the limiting factor in the reaction.
