Active transport is a process requiring energy in which a substance crosses the cell membrane. When the nerve cell is in its resting potential, there are the positively charged sodium ions and the negatively charged potassium ions. During depolarization, the neuron fires, wherein the active transport plays its role: the positive ions are forced in and the negative ions are forced out. When depolarization is done, these ions are again back to normal through active transport.<span>

True, because computers are digital machines, as they can read information.
Answer:
Yes or no
Explanation:
If the disease is genetic then the answer is yes because identical twins have the same genes.
If the disease is viral or bacterial than the answer is no because identical twins are growing in a different environment and facing different bacteria and viruses. So if one is sick it's not compulsory that the second one is also sick it purely depends on the environmental conditions.
1. the hearts job is to propel blood throughout the body
2. i think the lungs trade CO2 for O2
3. they would go into hypothermic shock or something:p
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.
