Chromatin is the lose form of genetic material & the "normal state" of DNA, RNA, and protein in the nucleus and in the cells.
Chromosomes are a condensed form of chromatin. Chromatin becomes chromosomes in the Prophase of Mitosis and Prophase 1 and Prophase 2 of Meiosis. It loosens again in the Telophase in Mitosis and Telophase 1 and Telophase 2 in Meiosis.
Sister Chromatids are made when chromosomes replicate during the cell cycle. The replication leads to the formation of the chromatids. The chromatids are joined by a single centromere. They separate during Anaphase 2 of meiosis.
I hope that this helps! Sorry if it doesn't I tried my best to explain!
cooling of the power plant
b.
mining of uranium
c.
storage of radioactive waste
d.
monitoring the reactor
The correct answer is option B
The mining of uranium is harmful for both air and water. Uranium is a radioactive compound that is extracted by mining.
Uranium ore emits the gas named radon. The health effects of exposure to radon have particular problems. Significant rate of lungs cancer was observed during the 1940s and 1950s.
Water is used in the heap leaching of the uranium mining. The water can get mixed into the normal supply of water and harm the health of people.
Mining of the radioactive element Uranium has the following negative effects on both air and water such as contamination.
This is a a silvery-white metallic chemical element in the periodic table, with atomic number 92 and is commonly used to run nuclear power plant.
it exists in the air and when contaminates water could lead to kidneyailments in affected individuals which is why option B was chosen as the most appropriate choice.

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.

Curiousity-A scientist shows interest and pays particular attentions to objects or events. He asks questions and seeks answers.
Honesty-A scientist gives a truthful report of observations. He does not withhold important information just to please himself or others.
Open-Mindedness- A scientist listens to and respects the ideas of others. He accepts criticism and changes his mind if reliable evidence contrdicts his believes.

Why do most biologists believe that true commensalism does not exist?
an ecosystem usually has more parasites than hosts
animals of different species usually do not like to work together
the relationships are probably mutual or parasitic
animals of the same species rarely compete with one another
Answer:
its not host or partner the answer is parasite.
