Answer:
Leave is an important structure of plant body where food production occurs in the process of photosynthesis. In the leaves, small tiny pores called stomata are present on lower side of the leaf. These pores are responsible for the exchange of gases such as carbondioxide and oxygen. These stomata opens and carbondioxide is absorbed from the atmosphere and water from the soil. Both reactants combine in the presence of sunlight producing oxygen and glucose. Oxygen is released through stomata and glucose is stored in different parts of plant.

The saltwater causes osmosis, leading to water movement out of the zucchini cells, resulting in cell plasmolysis and a loss of firmness.
When a piece of zucchini is soaked in saltwater, the process primarily involves osmosis, leading to changes in the zucchini's texture and firmness. Osmosis is the movement of water across a semipermeable membrane, from an area of lower solute concentration to an area of higher solute concentration. In this case, the saltwater outside the zucchini cells has a higher solute concentration than the water inside the cells.
As the zucchini absorbs saltwater, water molecules within its cells begin to move outwards due to the osmotic pressure created by the higher concentration of salt outside. This results in the shrinking of the cell's cytoplasm away from the cell wall, a process known as plasmolysis. The loss of water from the cells causes the zucchini to become less turgid and firm.

Answer:
The cells in the zucchini shrink because they lose their water.
Explanation:
salt dehydrates things drawing out the water from the cells.
Answer:
The process in which one bacteria transfers DNA to another is called conjugation.
Explanation:
Conjugation is the process of transferring genetic material from one bacteria to another through direct cell contact. In the process of conjugation one bacteria acts as donor and transfer the DNA to a recipient. There is a specific DNA sequence present in Donor's DNA called fertility factor (F factor). F factor helps in the formation of pillus which is the site of genetic material transfer.
Answer:
Explanation:
the color of the leaves would be different (red, purple, yellow, etc.) and they would most likely fall off of the tree
B is the correct answer
A prokaryote cell has no distinct nucleus with a membrane and neither does it have other specialized organelle.
In a eukaryotic cell, the genetic material is DNA in the form of chromosomes which are found within a distinct nucleus.
Examples of prokaryotes Streptomyces soil bacteria (from which streptomycin antibiotic is derived), Escherichia coli bacterium and Streptococcus bacteria (which causes strep sore throat).
Examples of Eukaryotes include protozoa such as amoeba, fungi, plants, animals and generally all multicellular organisms.
The correct answer is actually A
