The answer lies with carbon's unique properties. Carbon has an exceptional ability to bind with a wide variety of other elements. Carbon atoms can form multiple stable bonds with other small atoms, including hydrogen, oxygen, and nitrogen. Carbon atoms can also form stable bonds with other carbon atoms.
The correct answer is Mitosis !! B !!
Mitosis did not do DNA varriations !!
Answer: C. 30 - 50 million years ago
Explanation:
Fossils found in layer Y formed 30 million years ago according to the graph above. Similarly, fossils found in layer Z formed 50 million years ago.
If a fossil (fern fossil) is found between layer Y and layer Z, it means that it formed between the years that the fossils in layers Y and Z formed which is 30 - 50 million years ago.
The answer is that the equatorial regions receive sun rays closest to the vertical (direct rays) because of their position relative to the equator where the tilting of the earth only mildly affects the climate. The climate along the equator changes very little through out the year and has summer like conditions for most of the year.
However the other regions may receive direct sun rays but for far more limited periods. In the months of July and August (summer months), the northern hemisphere is tilted towards the sun and receives the most direct rays. The opposite occurs in December and January when it is tilted away from the sun and thus winter sets in, whereas the southern hemisphere is at this time tilted toward the sun and receives the most direct sun rays.
Well fungi usually feed off of the decomposing matter of dead creatures and nutrients around it, while animals usually feed off plants or living things. fungi is a decomposer while animals are just consumers.
