How does DNA molecules show constancy and variation from one species to the next?

DNA replication follows the semi-conservative model, base pairing and complentary RNA are formed, in a '5 to '3 direction, so the new strands will have old and new material but look the same as the original strand. variation occurs due to the genetic mutation that alters the base-pairing which is sometimes due to a problematic polymerase"2 enzyme, and this mutation will alter the genes structure permanently.

How does variation ensure that a species to survive?
Creation of variation occurs in a species and help in the survival to species as the most suitable or favorable character pass next generation and under unfavorable condition only the most fit organism survive and help in continuation of the species.
Constancy of a chromosome number from one cell generation to the next is maintained through?
No of chromosomes is maintained by meiosis and fertilization .
How does the motion of the molecules change during melting?
The motion of molecules is accelerated.
Why does variation occurs?
Variation occurs because of mutations in the genetic code.Mutaions occur when one of the nitrogen bases are in the wrong spot like if aa is next to each other in the wrong sequence then the mutations occur
What is an example of a variation in a plant?
Biological variations occur in plants and animals when their physical appearance differs to that of the general population. Mostly this occurs through a genetic mutation, and as such if the mutation proves to be an advantage to the plant in order to survive and thrive it can be carried forward in its genes to the next generation. An example of a variation in a plant would be a species that developed tendrils to help it climb trees in search of sunlight, where the vast majority of plants don't do this.

How does the creations of variations in species promote survival?
Creation of variation occurs in a species and help in the survival to species as the most suitable or favorable character pass next generation and under unfavorable condition only the most fit organism survive and help in continuation of the species.
What is the next Airbus?
A variation of the Airbus A380
Constancy of a chromosome number from one cell generation to the next is maintained through?
No of chromosomes is maintained by meiosis and fertilization .
How does heat from a radiator transfer?
The heat energy from the radiator transfers that energy to the air molecules next to it. Those molecules then transfer that heat energy to the molecules next to them. This process continues until all the molecules are at the same energy level. This process is call conduction.
What variation statement can be drawn from the given data set?
= ",n,"!"; % Print the result! next n; % On to the next factorial up. END
As the concentration of molecules outside a cell increases more molecules will enter the cell?
the molecules are moving down their concentration gradient BACK NEXT
What is the difference between flower genus and species?
A genus is the next higher taxon up from species. It is a group of closely related species.
How does the motion of the molecules change during melting?
The motion of molecules is accelerated.
Which state of matter has molecules vibrating next to each other?
All substances always vibrate and shake next to each other: it's how we perceive temperature. I don't think I quite understand this question. But this may help: If a substance is in solid form, it is the most compact. The molecules are vibrating next to each other very closely. If a substance is in liquid form, it is somewhat compact. Molecules are vibrating next to each other, but not as closely. If a substance is in a gaseous form, it is spread out and crazy: and like every other state of matter, the molecules are vibrating next to each other.
Why does variation occurs?
Variation occurs because of mutations in the genetic code.Mutaions occur when one of the nitrogen bases are in the wrong spot like if aa is next to each other in the wrong sequence then the mutations occur
What will the next human species look like?
Various theoriest have proposed that human head sizes will increases (in order to contain the ever enlarging brain which humans possess), and that fingers will become more dextrous. It is estimated that another few hundred thousand years could pass before there is enough genetic variation to make a subsequent human species distinct enough from our own.
