Answer:
The statement '<em>the genetic material of the original cell is divided among the new cells</em>' describes how cells are produced in meiosis process.
<u>Explanation: </u>
<em>In meiosis a single cell is divided into twice to form four cells and it contains the original half amount of 'genetic information'.</em> In meiosis, the two cells are called daughter cells are produced, and each identical cells to the parent cell meiosis are produced four haploid cells and mitosis are produced two diploid cells.
<em>The meiosis cell division is to reduces the number of 'chromosomes' in the parent cell by its half portion and also they produce four gamete cells.</em> In this process they required to produce 'eggs and sperm' cells for the sexual reproduction .It is the main aim to make a daughter cells with same half so many 'chromosomes' as the starting cell.
An Egyptian pyramid that is 4500 years old will be considered as a fossil in this scenario.
<h3>What is a Fossil?</h3>
This is defined as trace of an animal or plant of a past geologic age that has been preserved in Earth's crust.
Since it has been discovered that the egyptian pyramid contains thousands of marine fossils then it can be generally referred to as a fossil.

Explanation:
The beneficial uses of bacterial toxins in medicine are more and more used lately. For example, Botulinum toxin is a toxic protein produced by the bacterium Clostridium botulinum which has paralytic effects (injection of this toxin into muscle relax specific muscles). Botulinum toxin accomplishes his effects on the neuromuscular junction where he prevents the release of the neurotransmitter acetylcholine (Ach). Utilization of this toxin is in the treatment of various muscle spasms. It is also used in the treatment of migraines. Diphtheria toxin is also one of the toxins used for medical purposes for the treatment of cutaneous and non-Hodgkin T-cell lymphomas. <span>Some bacterial toxins can be used in the treatment of tumours. For example, immunotoxin, which is protein made by fusion of modified antibody and toxin.The antibody binds to an antigen on the target cell, the toxin then enters via endocytosis and kills the cell. Commonly used bacterial toxins in immunotoxins are Diphtheria toxin and the Pseudomonas exotoxin.</span>
<span>Only one sperm normally fuses
with an egg because if more than one sperm fuses, through a process
called polyspermy, development of the zygote usually stops.
</span>
<span>Fertilization of one egg by
two sperm is possible, but the resulting zygote is almost never viable
because such a zygote would have three sets of chromosomes instead of
the normal two. This condition, called triploidy, is usually
incompatible with life. Those rare triploid infants that do survive to
term have severe and multiple birth defects and rarely live more than a
few days. </span>
