Part A What is a telomere? What is a telomere? the mechanism that holds two sister chromatids together the ends of linear chromo
GrogVix [38]

Answer: B the ends of linear chromosomes.

Explanation:

Based on structure, telomeres are located at the end of chromosomes; they are protective caps that bind the genes at the end of the chromosomes in order to prevent it from interchromosomal fusion (clumping) and degradation (broken down). Simply, they serve the same role as plastic caps to the tip of shoe laces; preventing it from unraveling.

.

Generally, telomeres becomes short in length with time. At this stage they become weaken, and breaks down. The affected the cells basic replication activites, and therefore the functions. These non-functioning cells accumulated in body organs, and made them to degenerate .This reduced longevity, leading to death of cells. However the shortening of the length is an advantage to prevent the spread of cancer in cells because I naturally stops the uncontrivable growth of cells

Therefore the longer the length of    telomeres at the genome end of chromosomes, the higher the rate of replication of the concerned cells, and hence the increase in the age of the cell

What type of reproduction do ferns use
Elena-2011 [213]

They both use a reproductive strategy called alternation of generations, where there are two different reproducing morphologies: a diploid sporophyte, and a haplod gametophyte. The sporophyte produces spores by meiosis (2N -> N), which disperse and form the gametophyte, which produces gametes by mitosis (N ->N). Two of those gametes fuse to create a diplod zygote (N + N -> 2N), which becomes the new sporophyte

There are differences between the two types of plants, especially the relative size of the sporophytes and gametophytes, but they both use this kind of reproductive strategy.
