Answer:
the conversion of sunlight energy into chemical energy
the process by which plants, some bacteria, and some protist use the energy from sunlight to produce sugar
Explanation:
<em>Photosynthesis is a process during which the energy present in the sun is converted into chemical energy and locked up in an organic compound. The energy from the sun is trapped by the chlorophyll - a compound found in green plants, some bacteria, and some protists - and utilized to synthesize sugar along with inorganic materials such as carbon dioxide and water. </em>
The entire process of photosynthesis consists of multiple steps whose chemical equation can be summarised below:
The heavenly body referred to in the question above is Jupiter. It is approximately 5.2 AU away from the sun. It is classified under the outer planets, so the answer is C. The Kuiper belt is around 50 AU from the sun. While the asteriod belt is 3.2 AU away. As for the inner planets, Mars, Earth, Venue, and Mercury are 1.5, 1, 0.7 and 0.39 AU away from the sun respectively.
During the repolarization phase of an action potential which of the following is the primary activity in the membrane of the post-synaptic cell?
A) Sodium ions are flowing out of the cell.
B) Sodium ions are flowing into the cell.
C) Potassium ions are flowing into the cell.
D) Potassium ions are flowing out of the cell.
Answer:
D) Potassium ions are flowing out of the cell.
Explanation:
The threshold opens both voltage-gated Na+ channels and the voltage-gated K+ channels. The voltage-gated K+ channels are very slow in opening. Therefore, they open when the voltage-gated Na+ channels are closing. The opened voltage-gated K+ channels are responsible for the repolarizing phase.
During this phase, the inflow of Na+ becomes less as the responsible channels are inactivated. The opened K+ channels allow the K+ to move out of the post-synaptic cell. It results in the generation of negative charge inside the cell membrane as the membrane potential reduces +30 mV to −70 mV.
Answer:
C) are sequence-specific DNA endonucleases
B) degrade foreign DNA that enters a bacterium.
Explanation:
Restriction enzymes are the proteins that cut the DNA at a specific sequence.
<u>Restriction enzymes are also known as restriction endonuclease produced by bacteria that recognizes a specific sequence on DNA and split it by catalyzing the hydrolysis or addition of water molecule. </u>So, Restriction enzymes are sequence-specific DNA endonucleases.
The biological role of restriction enzymes is to restrict the entry of foreign DNA into the bacterium. <u>Restriction enzymes have the ability to restrict the number of bacteriophage strains that affect bacteria.</u>
Hence, the correct options are "C and B"
