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
If your asking if you can prove everything by science then no but people will try they will give out theories and try to find solutions that they can't. And if your asking if your able to prove all things that happen/the explanations scientifically then the answer is no. Take how the world was made for example nobody knows how it is made. The scientists are trying to prove it was created by some big bang when in reality nobody really knows that's just a theory. One of many theories.
The population of beetle will increasingly become green, with subsequent generations, until it becomes the dominant phenotype. This is because the green beetles will be able to camouflage with their environment and avoid being preyed on by the birds as compared to the black beetles. Therefore, the green beetle will have a high chance of reaching the reproductive stage and passing its genes to the next generation as compared to the black beetle.
Metabolism
Metabolism is a body function which enables a cell to process and create needed organic compounds that will be used for cell processes like repairing, rejuvenating and energy.
Ecology, genetics and evolution are themes, subdisciplines and subtopics of biology -the study of life.
Each Golgi stack has two distinct ends, or faces. The cis face of a Golgi stack is the end of the organelle where substances enter from the endoplasmic reticulum for processing, while the trans face is where they exit in the form of smaller detached vesicles.
