Answer:
It exhibits traits and metabolic instructions of the cell.
Explanation:
A DNA strand is a thin long molecule, with an average width of just around two nanometers. The remarkable thinness of the DNA strands allows them to be bundled very tightly fitted inside cells. Once DNA has been replicated adequately during the process of cell division, it is further wrapped together under a mechanism known as supercoiling. A non-condensed DNA is further condensed during supercoiling using a special protein known as a histone. A part of DNA packed around a large cluster of histones is called a nucleosome. Additional condensation leads to a chromosome or the most compact type of DNA that fits into the nucleus. It is also worth noting that this wrapping does not merely align DNA into a cell, but serves other objectives such as protecting DNA, thus ensuring metabolic instructions to the cell.
Answer:
Do you mean the definition?
I think it is "population density". Population density is the number of individuals per unit area or volume.
Explanation:
Answer:
Natural Gas
Petroleum
Coal
Explanation:
1) Ethanol is not a fossil fuel
2) 94% of ethanol is produced from the starch in corn grain
3) fossil fuel definition: a natural fuel such as coal or gas, formed in the geological past from the remains of living organisms.
4) fossil fuels are usually found in the earth's crust... not made from corn grain
<span>The only incorrect
answer is d. within very short spans of time.<span>
<span>In his
Theory of Evolution, Darwin
noted three patterns of biodiversity:</span>
<span>1.
Species vary globally - different, but ecologically similar animal species inhabit separate habitats around the
Globe, but again, these habitats are ecologically similar.</span>
2.
Species vary locally - different animal species that are related to each other,
may occupy different habitats in an area not so far away.
<span>3.
Species vary over time - some traits become more common, other less common.
