Answer:
the four zones found in the ocean:
<em>the intertidal zone,</em> which is the area of the seashore that's underwater at high tide and above water level at low tide. this zone also has various kinds of organisms, like seastars, sea urchins and a lot of different species of coral !
<em>the pelagic zone,</em> which could be described as all of the sea other than the sea along the shoreline or the bottom of the ocean. it's funny because the word is actually derived from ancient greek, and the word pelagic literally means
"<em>open sea</em>" !
<em>the abyssal zone,</em> which can also be called the abyssopelagic zone (i don't even know how to say that-) describes the "depths" or the very bottom of the ocean, especially between about 10,000 and 20,000 feet (3,000 and 6,000 m) down !
and <em>the benthic zone, </em>which is made up of the "bottom", like the bottom of a lake or ocean floor, the sediment surface, and some sub surface layers. there's actually organisms living in that zone, too, and they're called benthos ! (i think that's really cute, lil benthos uwu)

A mutation is a change in a DNA sequence. Mutations can result from DNA copying mistakes made during cell division, exposure to ionizing radiation, exposure to chemicals called mutagens, or infection by viruses. Germ line mutations occur in the eggs and sperm and can be passed on to offspring, while somatic mutations occur in body cells and are not passed on.
Recessive mutations inactivate the affected gene and lead to a loss of function. For instance, recessive mutations may remove part of or all the gene from the chromosome, disrupt expression of the gene, or alter the structure of the encoded protein, thereby altering its function.
Answer:
nearly one million tons per year
Explanation:
Midgely would receive the Society of Chemical Industry’s Perkin Medal for this research in 1937; in 1941, he was awarded the Priestley Medal, the American Chemical Society’s highest award, for his contributions to chemistry.
By the early 1970s, CFCs were in widespread use, and worldwide production of the compounds had reached nearly one million tons per year, representing roughly a $500 million slice of the chemical industry.
The correct answer is A.
Secondary growth in plants allows many woody and non woody plants to grow tall and strong. The growth basically occurs in the roots and the stems and it is controlled by lateral meristem. Examples of non woody plants that undergo secondary growth include: carrot, potato, tuber, etc.<span />
