Answer:
D Flow of protons across an electrochemical gradient
Explanation:
The chloroplast adenosine triphosphate (ATP) synthase uses the electrochemical proton gradient generated by photosynthesis to produce ATP, the energy currency of all cells. Protons conducted through the membrane-embedded Fo motor drive ATP synthesis in the F1 head by rotary catalysis.
In chloroplasts, photosynthetic electron transport generates a proton gradient across the thylakoid membrane which then drives ATP synthesis via ATP synthase.
The light-induced electron transfer in photosynthesis drives protons into the thylakoid lumen. The excess protons flow out of the lumen through ATP synthase to generate ATP in the stroma.
Majority of ATP is produced by OXIDATION PHOSPHORYLATION. The generation of ATP by oxidation phosphorylation differs from the way ATP is produced during glycolysis.
Electrons are passed from one member of the transport chain to another in a series of redox reactions. Energy released in these reactions is captured as a proton gradient, which is then used to make ATP in a process called chemiosmosis.
D.Flow of protons across an electrochemical gradient
is the correct answer

Scientists use a process called gel electrophoresis to separate DNA fragments. The process involves placing a mixture of DNA fragments at one end of a slab of porous gel. Then a power source is used to generate an electric potential across the gel.
The diagram shows the process of gel electrophoresis. First, DNA fragments, mixed with a restriction enzyme, are placed at one end of a slab of gel. Then a power source is applied; the longer DNA fragments stay near the negatively charged end, and the shorter fragments move toward the positive end.
Gel electrophoresis is successful because of which property of the DNA fragments?
A. The DNA fragments may be positively-charged, negatively-charged, or neutral.
B. The DNA fragments travel at different speeds through the gel.
C. The DNA fragments travel at the same speed through the gel.
D. The DNA fragments chemically react with the gel in different ways.

C. The DNA fragments travel at different speeds through the gel.

What does it mean that there is both unity and diversity of life at the level of the cell?
Answers
Answer:
All livings organisms are with unicellular origin. The cells have a common structure like cell membrane, DNA , RNA and necessary enzymes. The genetic code of protein synthesis is almost similar with few exceptions. This shows unity in design.
Further evolutionary changes took place due to environmental stress. The genome of each species is designed as per need and efficiency. This is diversity.
This is true with all five kingdoms of life that is monera, protista, fungi, plantae and animalia.

produces genetically identical diploid cells
Answers
Answer: C.) Produces genetically unique haploid cells
Explanation: Meiosis will produce genetically unique cells because they are meant to pass onto offspring, and they are haploid because there are half the number of chromosomes in them. The organism will receive 2 sets, one from each parent, so that is why each parent who's cells undergo meiosis have to produce haploid cells.

What are capillaries?
Select one:
a.
blood cells that fight infection
b.
vessels through which nutrient and gas exchange take place
c.
chambers of the heart that pump blood throughout the body
d.
the liquid part of the blood that transports hormones
Answers
b. Capillaries are vessels through which nutrient and gas exchange take place.
Capillaries are the smallest blood vessels in the body and are responsible for facilitating the exchange of nutrients, gases, and waste products between the bloodstream and surrounding tissues. They connect the arterioles (small branches of arteries) and venules (small branches of veins).
Capillaries have thin and permeable walls, consisting of a single layer of endothelial cells. This structure allows for the exchange of substances between the blood and surrounding tissues. Oxygen and nutrients diffuse out of the capillaries into the tissues, while carbon dioxide and waste products from cellular metabolism diffuse into the capillaries to be carried away.
The extensive network of capillaries ensures that every cell in the body is located in close proximity to a capillary, allowing for efficient exchange of substances. This exchange includes the delivery of oxygen and nutrients to the cells, as well as the removal of carbon dioxide and waste products.
While blood cells, such as red blood cells and white blood cells, are present in the capillaries, they are not the defining characteristic of capillaries. Instead, capillaries are primarily associated with facilitating the exchange of substances between the bloodstream and the surrounding tissues.
Therefore, option b is the correct answer as it accurately describes the role of capillaries in facilitating nutrient and gas exchange.
