The major causes of biodiversity decline are land use changes, pollution, changes in atmospheric CO2<span> concentrations, changes in the nitrogen cycle and acid rain, climate alterations, and the introduction of exotic species, all coincident to human population growth. For rainforests, the primary factor is land conversion. Climate will probably change least in tropical regions, and nitrogen problems are not as important because growth in rainforests is usually limited more by low phosphorus levels than by nitrogen insufficiency. The introduction of exotic species is also less of a problem than in temperate areas because there is so much diversity in tropical forests that newcomers have difficulty becoming established (Sala, </span>et al.<span>, 2000).</span>
Answer:
2.) binary fission
Explanation:
In asexual reproduction, a single parent is involved in the process of reproduction. The offspring that emerge out from the parent are identical and similar to each other. Binary fission is a type of asexual reproduction in which the cells of the parent spilled and form two daughter cells that are identical to each other.
<span>What ensures that DNA molecule is replicated
exactly as its original strand is with the ability of the DNA to make way and
let the base pairs match with each base. This enables them to form the same
strands so that it is identical and not different with the original strand.</span>
The plasma membrane and several cytoplasmic organelles such as the ER, Golgi apparatus, secretory granules and vesicles, lysosomes, endosomes, form an endomembrane system.
Good luck!
