Answer:
The repeating subunits of DNA are ribonucleotides whereas in RNA they are deoxyribonucleotides.
Explanation:
Ribonucleotides are repeating subunit of RNA while the deoxy-ribonucleotides are repeating subunits of DNA. That why RNA full form represent the ribonucleic acid and DNA represent deoxyribonucleic acid.
Actually the word "deoxy" means one oxygen is removed or less in DNA. The DNA lacks the one oxygen atom of hydroxyl group at carbon number two of ribose sugar. While RNA have the hydroxyl group at carbon number two of hydrogen atom.
The removal of one hydrogen atom in DNA make it more stable than RNA because DNA is made specifically to store genetic information and needed to be strong. The oxygen atom in RNA makes it vulnerable for attack by other biological molecules.
Answer: Hewo, there! your answer is Below
B. Warm all year long
Explanation:
here are normally only two seasons in tropical climates, a wet season and a dry season. The annual temperature range in tropical climates is normally very small. Sunlight is intense.
Hope this helps!
Have a great day!!
Answer:
The correct answer will be- Transmission electron microscope
Explanation:
A Microscope is an optical instrument designed to view the microscopic things which could be living or non-living around us.
The internal structure of a microscope can be viewed by a light microscope mainly dark-field microscope but a detailed structure of a microscope can be viewed by an electron microscope mainly a transmission electron microscope.
The transmission electron microscope studies the internals structure of the cell by creating the 2D images by passing the beam of electrons through the specimen.
Thus, a transmission electron microscope is the correct answer.
Explanation:
The equation that shows the equilibrium reaction of carbon dioxide in the blood is the following one:
<h3>
CO₂ + H₂O ↔ H₂CO₃ ↔ H⁺ + HCO₃⁻</h3><h3 />
This equation describes the bicarbonate buffer system which regulates the pH of the blood.
- During hypoventilation, the CO₂ produced by the cells through metabolism is not released fast enough, so CO₂ levels in the blood increase. In this situation, the equation shifts towards the right, and an excess of protons is produced, therefore decreasing the pH and causing acidosis.
- During hyperventilation the breathing is very rapid and CO₂ is exhaled from the body at a very fast rate. In this situation, the CO₂ levels in the blood decrease, the equation shifts towads the left and the concentration of H+ thus decreases, causing alkalosis.
