Plants need to have chloroplasts, because chloroplasts are responsible for converting solar energy into chemical energy. By doing this, the plant is able to perform photosynthesis, which then provides the food energy that the plant needs. Without chloroplasts, the plant would die.

Thanks won't tell them anything and neither anyone else
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
Answer:
the penguins have a special care process since the hatching of the egg, the newborns receive care from their parents and have warmth from them placing themselves between their paws, the parents take turns caring for them and when the father is not with the chick, he goes in search of food, which he gives regurgitated, then the cris can go to a kindergarten where others of the same age are cared for by a herd of penguins, however his parents go to the sea and feed and continue to bring food to their son, this process it is kept until they change plumage and are ready to get their food on their own.
