Answer: The cell is the structural and functional unit of all living organisms, and is sometimes called <u>the "building block of life."</u> Some organisms, such as bacteria, are unicellular, consisting of a single cell.
Answer:
It is false. carbohydrates are stored in form of glycogen.
A mutation is a permanent change in the DNA sequence of a gene. This can be beneficial if the change gives a new function to or improves the function of that gene.
<span>The above is a definition. But one must really define "beneficial". Some regard it as beneficial if it helps the specific individual who has it. Others would think it beneficial if it produced some survival advantage that insured more descendents for that individual. </span>
<span>It is the difference between a mutation that allowed for greater athletic ability, but a decreased desire for offspring, versus a more moderate athletic enhancement, but a greater desire for offspring. </span>
<span>The small percentage of ways to improve an organism, versus the near infinite ways of harming the organism, mean that most mutations are not going to be beneficial. At best, they will be "inconsequential" - such as a new shade of eye color, or a mole on a section of your skin. </span>
The populist notion of "powers" that can come from mutations is wildly inaccurate. Even assuming a minor power like the ability to see infra red radiation would take thousands upon thousands of mutations over vast amounts of time. A mutation for blindness is far more likely.
<span>It should also be noted that the traditional model of evolutionary theory no longer applies to man. We don't allow changes in our environment, and without such changes, there is no need for one trait more than another to predominate. After all, it is irrelevent that a mutation might allow for greater speed in running, when everyone drives a car.</span>
The Equator line does not pass through the north and south poles. This line divides the Earth's planet into two hemispheres.
The Equator can be defined as an invisible line located at the center of the Earth (0 degrees latitude).
This invisible line (Equator) divides the Earth into two hemispheres: the northern hemisphere and the southern hemisphere.
The Equator is a circle of latitude, and the distance of this imaginary line is approximately 40,000 km in circumference.

Answer:
Explanation:
Prokaryotic cells are very simple so they have:
circular chromosome
smaller than eukaryotic cells
lack nuclei
have cell walls
