What step in photosynthesis may occur during day and night? A.Light independant reactions B.Light dependant reactions c. Photolysis
Answer:
a is the answer
Explanation:
Light independent reactions of photosynthesis may occur during day and night.
STAGES OF PHOTOSYNTHESIS:
Photosynthesis is a metabolic reaction undergone by green plants to obtain their food using energy from sunlight. Photosynthesis is a process that involves two major stages: light independent reactions and light reactions. Light dependent reactions occur strictly under light conditions because light is needed to break down water molecules in a process called photolysis. In the light dependent reactions, water is broken down by light to give oxygen gas. In the light independent reactions, carbon dioxide is required.However, light independent reactions may occur during day and night. This is because light independent reactions does not require light to occur.

2.
condensation of water vapor during the day, and evaporation of water during the night
3.
convection resulting from temperature and pressure differences above land and water
4.
greater radiation from the warmer ocean during the day and from the warmer land at night
Submit Answer
Answer:
3. convection resulting from temperature and pressure differences above land and water
Explanation:
Due to the the difference between the ability of land and to water to absorb and radiate heat energy, the land gets heated up by the sun more quickly than water during the hot afternoons. As a result, the air above the land surface gets heated up more quickly than that above water. Warm air being less dense than cold air will rise above to atmosphere creating a low pressure area on land. On the other hand, air above water is not heated up as quickly, thus the dense cooler air over water will rush in and replace the warm air that has risen above the land surface.
At night, the land cools off more easily than water, hence the air above the land surface is cooler. On the other, water does not lose heat as quickly as the land, hence the air above the water surface is warmer than that over land. Warm air over the water surface will rise above, while colder air from land will replace it.
A car advertised states that it can accelerate from rest to 70 m/s in 7 seconds. What is its acceleration?
Answer:
10[tex]m/s^{2}[/tex]
Explanation:
Formula to find acceleration is :
Acceleration = [tex]\frac{ChangeInVelocity}{TIme}[/tex]
OR
Acceleration = [tex]\frac{Final velocity-Initial velocity}{Time}[/tex]
= [tex]\frac{70 - 0}{7}[/tex]
= [tex]\frac{70}{7}[/tex]
= 10[tex]m/s^{2}[/tex]
The data showed that recently the alligator population has decreased. How could the decrease in the alligator
population affect the other populations? Be sure to explain whether the gar population, the diving duck population, and
the crab population will change, and why.
Answer:
the gar population will increase, the diving duck will decrease slightly and the crab population will decrease
Explanation:
Since the alligator population will decrease, the gar population won't have anything to limit their population, so they will increase fast. The crab population will decrease fast as there are more gars to eat them. The duck population will decrease slightly as the gar is eating more crabs then the duck

Which of the following is the correct sequence of events in Protein Synthesis?
A. mRNA strand is formed, mRNA is processed, polypeptide chain is formed, protein is modified
B. Polypeptide is formed, mRNA is processed, polypeptide chain is formed, mRNA is modified
C. mRNA strand is formed, polypeptide chain is formed, mRNA is processed, protein is modified
D. Polypeptide chain is formed, protein is modified, mRNA strand is formed, mRNA is processed
Answer: A
Explanation:
It can't be B or D because to get the polypeptide chain, we need the mNRA first to go through the ribosome. It's not C because after the mRNA is generated in the nucleus, it undergoes some modifications like splicing and the addition of the 5' cap and 3' tail.
The answer to the question is option A which is mRNA strand is formed, mRNA is processed, polypeptide chain is formed, protein is modified.
What is Translation?
In its most basic form, expressing a gene implies producing its matching protein, and this multi-step process comprises two primary phases. The information in DNA is converted to a messenger RNA (mRNA) molecule in the first phase, which is known as transcription.
During transcription, the DNA of a gene acts as a template for complementary base pairing, and an enzyme called RNA polymerase II catalyses the creation of a pre-mRNA molecule, which is subsequently processed to form mature mRNA. The mRNA that results is a single stranded copy of the gene that must then be translated into a protein molecule.
The genetic coding is used to "read" the mRNA, which connects the DNA sequence to the amino acid sequence in proteins, during translation, the second key step in gene expression.
Each codon in mRNA is made up of three nucleotides and represents a different amino acid.
As a result, The mRNA sequence serves as a template for constructing the chain of amino acids that comprise a protein in the correct order.
So we can conclude that first mRNA strand is formed then mRNA is processed, then polypeptide chain is formed and protein is modified.
