process A is meiosis, you can see that the gamete(haploid cell) results from the diploid cell. The gamete has n chromosomes(39), whereas the diploid cell has 2n(78)
process B is fertilization the two gametes(haploid) fuse together to form the zygote(diploid)
Process A allows the chromosome number in the dog cells to be reduced by half. This is only possible due to meiosis as it undergoes 2 phases of meiosis/cell division which is meiosis I and II. (From 2n to 4n to 2n to n)
(After mitosis, the chromosome number will remain constant even though DNA replication occured in S phase, as there is only 1 phase of mitosis/cell division, so from 2n to 4n back to 2n)
Process B allows the dog gamete cells to undergo fertilization and produce a zygote, therefore the chromosome number returns back to 2n.
(Pollination only occurs in plants, not in animals such as dogs and humans)
The purpose of fungi and algae is to decompose dead plants and animals to break them down into smaller molecules that can be used by other members of the ecosystem
staw or straw? But, never the less, normal insulation hurts the environment. while being manufactured, the factory's blow smoke. while straw/staw do not have to be built, so there for wont hurt the environment.
