The high-energy batteries from the question above are used to power another very important reaction in photosynthesis. What is the reaction?
Answer:
This question is incomplete but it can be answered based on general understanding.
The reaction is CALVIN CYCLE OR LIGHT-INDEPENDENT REACTION
Explanation:
The high energy batteries being referred to in this question IS ATP. ATP is an energy-storing molecule produced in the first stage or reaction of photosynthesis called LIGHT DEPENDENT REACTION. Photosynthesis, which occurs in two stages, produces ATP molecule in the first stage as a result of the charging of ADP into ATP.
The ATP molecule, which serves as a high energy battery, is used to power the second stage of photosynthesis called LIGHT INDEPENDENT REACTION OR CALVIN CYCLE in order to yield sugars.
Crossing over and fertilization both result in which of the following
A.transcription
B.increase in genetic variation
C.an increase in the chromosome number
D. horizontal gene transfer
Answer: increase in genetic variation
Explanation:
Which of the following accurately describes the process of crossing over?
А
Crossing over occurs before replication and non-sister chromatids exchange gene segments to make new combinations of genes.
B
Crossing over occurs after replication and non-sister chromatids exchange gene segments to make new combinations of genes.
с
Crossing over occurs before replication and only sister chromatids exchange gene segments to make new combinations of genes.
D
Crossing over occurs after replication and only sister chromatids exchange gene segments to make new combinations of genes.
The statement that accurately describes the process of crossing over is that crossing over occurs after replication and non-sister chromatids exchange gene segments to make new combinations of genes. So, the correct option is B.
What is Crossing over?Crossing over is a process through which there is an exchange of genetic material between non-sister chromatids of a homologous chromosome.
After the replication process, the amount of genetic content gets doubled and arranged in the form of chromatids. Two chromatids of the same chromosomes are known as sister chromatids. And those two chromatids of homologous chromosomes are known as non-sister chromatids.
Therefore, crossing overs occurs after replication, and non-sister chromatids exchange gene segments to make new combinations of genes.

Energy-storing sugars are made during the __________ in photosynthesis.
Answer:
Photosynthesis occurs in two stages. In the first stage, light-dependent reactions or light reactions capture the energy of light and use it to make the energy-storage molecules ATP and NADPH. During the second stage, the light-independent reactions use these products to capture and reduce carbon dioxide.
Explanation:

Plants and other living things use photosynthesis to convert light energy into chemical energy, which is then released via cellular respiration to power the organism's activities.
How does sugar get its energy from photosynthesis?Plants use their leaves to capture light energy during photosynthesis. Water and carbon dioxide are converted by plants into a sugar called glucose using the power of the sun. Plants use glucose as a source of energy and to create other compounds like cellulose and starch.
Light, water, and carbon dioxide (CO2) are converted into energy and sugar inside the chloroplasts of leaves (glucose). Sunlight is transformed into energy-storing molecules in the plant cells using water. These molecules' energy is subsequently utilised to convert CO2 into glucose.

If you were to examine a plant or animal cell under a microscope, what phase of the cell cycle would you most likely see? Explain your reasoning.
Answer:
Explanation:
During interphase (1), chromatin is in its least condensed state and appears loosely distributed throughout the nucleus. Chromatin condensation begins during prophase (2) and chromosomes become visible. Chromosomes remain condensed throughout the various stages of mitosis (2-5).
If you were to examine a plant or animal cell under a microscope, you would most likely see the interphase of the cell cycle. This is the resting phase.
What is the cell cycle?The cell cycle may be defined as the entire sequence of events happening from the end of one nuclear division to the beginning of the next. The cell cycle can be divided into two phases. They are as follows:
InterphaseM-phase (Division phase).During the interphase of the cell cycle, the cell undergoes normal growth processes with the replication of DNA in the synthesis phase. Chromosomes are observed in a little bit condensed state during the mitotic division.
Apart from this, cells do not undergo many series of alterations. It follows the path of rest, and hence it is known as the resting phase. Chromatin is somehow observed in a condensed state loosely distributed throughout the nucleus of the cell.
Therefore, the interphase of the cell cycle would you most likely see, when you were to examine a plant or animal cell under a microscope.

Which of the following is NOT a common problem associated with inorganic fertilizers?
O They are often subject to leaching
O They can dry out, or desiccate, seedlings and young plants
O They may release insufficient nutrients and can deplete nitrogen in the soil
They can cause toxic residues to appear in conventionally grown fruits and vegetables
Answer:
They can cause toxic residues to appear in conventionally grown fruits and vegetables
Explanation:
Since inorganic fertilisers are made with chemical and such, they should not produce toxins.
Overuse of inorganic fertilizer destroys the physical characteristics of soil, hence, option d toxic more in conventionally grown vegetables and fruits is correct.
What are the problems associated with inorganic fertilizers?Many, such as anhydrous ammonia, urea, urea-ammonium nitrate solutions, triple superphosphate, ammonium phosphates, and potash muriate, can be administered directly (potassium chloride).
Compound fertilizers are chemical or physical blends of pure ingredients. As a result, excessive use of inorganic fertilizers has resulted in soil and air.
Water pollution due to nutrient leakage, soil physical features deterioration, toxic chemical buildup in water bodies, and so on, as well as serious environmental concerns and biodiversity loss.
Therefore inorganic fertilizers can cause toxic residue to appear in fruits and vegetables, hence option d is correct.
