Answer:
The correct answer will be option-D
Explanation:
Stem cells are the cells which have the ability to form different types of cells. They differentiate and specializes to perform different functions in the body and thus forms the different cells.
The differentiation and specialization are controlled at the gene level by different patterns of gene expression. The pattern of gene expression is not fully understood during development but research have shown that the gene expression is influenced by the different environmental signals and internal regulators.
Thus, option-D is the correct answer.
Answer:
Definition. The first metaphase of meisosis I encompasses the alignment of paired chromosomes along the center (metaphase plate) of a cell, ensuring that two complete copies of chromosomes are present in the resulting two daughter cells of meiosis I. Metaphase I follows prophase I and precedes anaphase I.
Explanation:
<span>Irwin Rosenstock developed this model. His research was used to show why so few people undertake preventative measures for diseases and illnesses. This model shows that people tend to think that they are healthier than they might be, so there is no need for them to get screenings or other types of treatment.</span>
Scientists believe that great apes such as chimpanzees and gorillas are more closely related to humans based on the evolutionary timeline because apes are larger than monkeys and have long legs and no tails. Apes are known to have larger brains than monkeys which makes them so closely related to us. This fact cancels out B and C for the answer. Also, apes (gorillas, orangutans, etc.) are much larger than monkeys (mandrill, lesula, etc.). This right away cancels out option D. What's left is option A which features body parts and comparisons that are comparatively accurate towards humans. Hope this helped :))
