A phylogeny is an evolutionary ”tree” of related
organisms that can be constructed by using
information obtained from the genetic material.
Genetic information is contained in all living cells,
in the form of long DNA molecules that take the
shape of connected double- stranded spirals
(DNA stands for deoxyribonucleic acid). DNA
spirals, or “helixes”, are tightly compressed in the
nucleus of every cell. Their information is
organized into a code made up of four small
molecules — the building blocks of DNA. The
molecules, called nucleotides, are labelled:
A (adenine), C (cytosine), G (guanine) and T
(thymine).
It is possible to draw conclusions about the
evolution of a group of plant or animal species,
and the relationships among them, by comparing
selected pieces of DNA.
Water helps keep cells in an even temperature despite temperature changes in the environment because water has a high heat capacity. Water can absorb a lot of heat before there’s a change in the temperature.
I hope this helped!
Ozone, which is also known as trioxygen, is a chemically bonded compound, and contains three oxygens.
<span>Natural selection causes favorable or superior traits in organisms. These favorable genes like that for tallness (women are attracted to taller men) would also them to reproduce more often and then these genes are passed on to the next generation. Over time, the tall genes become more common or frequent.
