Answer:
The research shows that for the cortex to evolve to be large, primates need a longer pregnancy, whereas a longer childhood is needed for a larger cerebellum to evolve. This means it is critical for infants to have the right environment to develop crucial skills.

Answer:
Organelle
Explanation:
The general name given to membrane bound structures eukaryotic cell that perform specific function for necessary cell survival.
Answer:
The correct answer is ''METAPHASE I.''
Explanation:
Metaphase I is the stage in which chromosomal studies are generally performed, because its morphology is very clear. The chromosomes, moved by the mitotic spindle, are placed in the center, between the two asters and form the so-called metaphase plate, in which the chromosomes are positioned in such a way that the kinetochore of each sister chromatid are oriented towards the opposite poles. Keeping chromosomes on the cell equator implies a balance between the forces of the microtubules that tend to move the kinetochores toward opposite poles, so positioning them in the center involves a great deal of energy.In each kinetochore, between 20-30 microtubules can be anchored, which exert traction force towards the pole from which they come, so the metaphase plate is maintained by the balance between the opposite forces of the poles on the chromosomes, which hold their sister chromatids by centromeric cohesin.
Mitochondria important for the cell that can't survive without it but blood cell is an exception. Blood is a tissue in animals so RBCs are animal cells and don't have mitochondria
Answer: cofactors.
Explanation:
Epinephrine, insulin and auxins are cofactors.
Cofactors are non protein substance which activate enzymes activity by increasing the rate of chemical reaction of enzymes. They are organic molecules and they assist in enzyme activity. They exist in performing some reactions the enzymes cannot perform alone.
For example, insulin activate enzyme hexokinase which phosphorylate glucose.
