Biology
1 answer:
balandron [24]2 years ago

Answer:

Explanation:Two of the nuclei (the polar nuclei) move to the center of the embryo sac and fuse together, forming a single, diploid central cell. This central cell later fuses with a sperm to form the triploid endosperm, which will ultimately provide nourishment for the developing embryo (analogous to yolk in animal eggs).

Kipish [7]

Regeneration in planarians depends on the presence of stem cells called neoblasts. These cells are distributed throughout the body and, when part of the worm has been amputated, they are activated to reform the tissues that have been removed.

Sodium Chloride is placed in water, what happens to the sodium ions and chloride ions in the solution.
blondinia [14]
Na+ ion in sodium chloride is attracted to the oxygen side of the water molecules, while the Cl- ion is attracted to the hydrogens' side of the water molecule

this causes the sodium chloride to split in water, and the sodium chloride dissolves into separate Na+ and Cl- atoms

What is the relationship between light intensity and gas production?
balandron [24]

Answer:

As light intensity increases (distance between lamp and plant decreases) the volume of oxygen (or the rate of bubble production) increases. This indicates that the rate of photosynthesis increases with light intensity. However, at sufficiently high levels of light intensity, the rate oxygen evolution remains constant.
