What are two microscopic features of cardiac cells that help to distinguish them from other types of muscle cells?ANSWER: CORTICOSTEROIDS
Explanation:
It's a piece of cake. Here we are provided with the information that a human cell with a chromosome number of 46, undergoes meiosis, what number of chromosomes will be in each daughter cell.
To solve this question first you must be aware about the word meiosis. Meiosis is a type of cell division. It's end product results in the formation of four daughter cells each having half the number of chromosomes as that of the parent cell.
Did you notice? That formed daughter cell will have half the number of chromosomes as that of the parent cell. Hence, 23 chromosomes will be in each daughter cell.
The question that Charles Darwin would be prompted to ask on his voyage is as follows: can selection in nature also lead to a new species over time?.
<h3>Who is Charles Darwin?</h3>
Charles Darwin was a British naturalist/scientist and founder of the theory of evolution by natural selection.
He is best known for his award-winning work on the origin of species, which he published in 1859. Darwin developed his theory from findings he made following a five-year expedition on board HMS Beagle.
According to this question, Darwin reviewed his observations after he returned home from his voyage studying the selective breeding of pigeons.

Answer:
Ozone is formed in the stratosphere naturally.
High energy solar radiation strike the oxygen atoms O2, the two atoms split apart. The freed atom collides with another oxygen atom O2 forming O3 (Ozone)
Ozone layer is destroyed when chloroflourocarbons and halons.
CFCs and halons cause chemical reactions that break down ozone molecules. Consequences ofnozone depletion are that UV radiations are not filtered and they reach the earth causing damage to eyes and skin.
Explanation:
Ozone layer is a protective layer which protects from UV damaging radiations. It is formed when oxygen atoms are broken down by photolysis and a freed oxygen atom combines with another amd form O3.
Ozone is being depleted now because chlorofluorocarbons (CFCs) and halons—gases found in aerosol spray cans and refrigerants—are released into the atmosphere they decrease the ozone's ultraviolet radiation-absorbing capacity.Ozone layer depletion causes increased UV radiation levels at the Earth's surface, which is damaging to human health. Negative effects include skin cancers, eye cataracts and immune deficiency disorders.
