Body cells perform mitosis in which they copy there chromosome prior to division, then dividing once, keeping there number of chromosomes, these are referred to as diploid cells. Sex cells perform meiosis where they double there chromosomes then divide twice, creating 4 cells, each containing half the chromosomes. These are referred to as haploid cells. The answer choice is choice 2. Hope I helped!
A.) Viruses
All cells are living things.
Viruses does not count as a living thing AND does not have the genetic makeup to be a cellular organism.
<span>Because biological activities such as muscle contraction, active transport, transmission of nerve impulse, and so on requires energy from ATP not from glucose. the role of Glucose molecules are providing hydrogen atoms to undergo oxidative phosphlyration(the formation of ADP to ATP). </span>
<span>Biodiversity is the number of species in a particular ecosystem.
It's generally considered more healthy for an environment to have large numbers of species. Many organisms come to depend on others so when you lose one species, it could cause others to be lost.
Example: Several trees in New Zealand required a giant extinct bird the moas to spread their seeds. They lost the trees because they lost the moas.
