There are two types of aging, primary aging and secondary aging.
Anything that cannot be controlled is called primary aging, things that can be controlled such as physical factors, are called secondary aging.

The answer is <span>hygrometer, will.
</span><span>Your <u>hygrometer</u> indicates that the relative humidity is very high. Rain probably <u>will</u> occur.
Hygrometer is an instrument used for measuring the relative humidity in the atmosphere. If the relative humidity is very high, then it rain will probably occur and vice versa.
Anemometer is an instrument used for measuring wind speed, thus it cannot be the right answer.</span>
Answer:
Cell phones emit radiofrequency energy, a form of non-ionizing electromagnetic radiation, which can be absorbed by tissues close to the phone. The amount of radiofrequency energy a person is exposed to depends on the frequency of the signal and the amount of time they spend on the phone. The Federal Communications Commission (FCC), the International Agency for Research on Cancer (IARC), and the American Cancer Society (ACS) all agree that more research is needed to determine the possible health effects of cell phone use. So far, there is no scientific evidence that proves that cell phone use causes cancer. Some studies have suggested a possible link between cell phone use and cancer, but more research is needed to confirm these results. The ACS does not recommend limiting cell phone use because the risk of cancer is still unknown.

Explanation:
Answer:
In the first step of meiosis I, the chromosomes/genetic material of the cell condenses into a visible form, into a form called heterochromatin. The nucleolus also disappears.
In the second step, a process called synapsis occurs. This is when homologous chromosomes align themselves, gene by gene.
In the third step, crossing over occurs. Segments of corresponding DNA are cut and exchanged between non-sister chromatids of the formed tetrads.
In the fourth step, the nucleus fragments, the nuclear envelope fragments, the two centrosomes (if we're talking about an animal cell) separate from each other as their asters and mitotic spindles (mostly microtubules (kinetochore and non-kinetochore) lengthen. The microtubules extending from the centrosomes can now connect to chromosomes.
Ell theory refers to the idea that cells are the basic unit of structure in every living thing.
