Reproduction in prokaryotes occurs primarily through the process known as Binary Fission.
Explanation:
the amount of CO2 found in the atmospheres varies over the course of a year how much of this variation happens because of the role of plants in the carbon cycle respiration occurs all the time but dominates during the colder months of the year resulting in higher CO2 levels in the atmosphere during those months.

Answer:
Unvaccinated person has naturally immune , cannot catched by this disease.
Explanation:
The white blood cells can recognise that these are not human protein . The invading or foreign protein is called an antigen . Antigen in the blood
starts the white cells making defence chemicals called antibodies. Some antibodies break up the antigens . This stops the antigen entering the body cells & makes it easier for the Phagocytes
to egulfs and digest antigens/pathogens & also
Lymphocytes produce antibodies to destroy pathogens.
Some bacteria produce toxins inside the body ,
Our white blood cells can also make antitoxins to
destroy the poison .
Antibodies and antitoxins help prevent microbes damaging the body . The help us fight off the. disease , giving us IMMUNITY to the disease.

Answer:
Nerve cells release chemical signals into synapses between them (short distance). They also transverse their lengths with an electrical signal that can result in signal travel along a series of cells (long distance).
Explanation:
Nerve cells release neurotransmitters in the synaptic cleft which are capable of affecting nearby cells such as other nerve cells and muscle cells. Neurotransmitter molecules include, among others, serotonin, acetylcholine, dopamine, norepinephrine and histamine. Moreover, the synaptic cleft is the space that separates a neuron cell and its target cell. On the other hand, neurons transmit signals through electrical impulses. Electrical impulses travel long distances in the body carried by axons of the nerves. Thus, nerve impulses connect the brain and spinal cord and they carry signals to different parts of the body.
