The number of chromosomes found within the cells of any given species is a constant number maintained through multiple generations. The accumulation of chromosomes is prevented because the process of meiosis creates – a
mutations that destroy extra DNA
b
genetically identical daughter cells
c
haploid gamete cells
d
offspring through asexual reproduction

c  haploid gamete cells

Explanation:

The vast majority of cells in the body are diploid, meaning they have two copies of every chromosome. However, like the question says, if during fertilization, the diploid cells fuse, then there will be 4x copies of every chromosome in the first generation, 8 in the second, and so on.

Meiosis creates haploid cells from diploid cells through one round of DNA replication and then two cell divisions to create haploid cells, one copy of each chromosome.

During fertilisation, when the gametes fuse, they make a diploid cell that develops into a new organism.

the nitrogen cycle provides nitrogen to the ecosystem from the atmosphere, ground and oceans. nitrogen is an important component of complex molecules such as amino acids and nucleotides, which lead to the creation of proteins and dna, the building blocks of all life. plants absorb nitrogen in the form of ammonium, nitrate ion and, on rare occasions, as amino acids. animals receive nitrogen necessary for biological processes from feeding on living or dead organic matter.
