Answer:
b) convolutions
Explanation:
The part that makes the outer rim of the cerebrum is the cerebral cortex. It is composed of gray matter. The billions of neurons of the cerebral cortex are organized in distinct layers. During embryonic development, enlargement of the brain is accompanied by even more enlargement in the gray matter of the cerebral cortex. However, it fits into the skull due to its folds which are also called convolutions or gyri. The cortical region rolls and folds on itself.
Answer:
The nervous system produces rapid responses while the endocrine system generates slow but long term responses.
Explanation:
The nervous system rapidly generates a response by sending the sensory and motor information in the form of nerve impulses. The rapid responses of the nervous system are compared with text messages that are delivered instantly to the other person.
On the other hand, the endocrine system produces a relatively slow response by releasing hormones. Therefore, it is compared with a letter that takes a few days, depending on the distance, to be delivered to the other person. However, the effects of the endocrine system are long-lasting as compared to the short term responses generated by the nervous system.
Answer: we dont have enough information.
Explanation:
Answer:
Genetic information is bundled into packages of DNA known as chromosomes.
Explanation:
Chromosomes can be described as thread-like structures made up of genes. A genes can be described as a hereditary molecule which is made up of a segment of DNA. Hence, a chromosome contains genetic information packaged into bundles of DNA.
The number of chromosomes vary for each organism. For example, the number of chromosomes in each somatic cell of the human body is 46. These chromosomes occur in the form of homologous pars.
The chemical division process called mitosis is split into the following 6 steps, such that: interphase<span>, prophase, </span>metaphase<span>, anaphase, telophase, cytokinasis. The firts step of mitosis is characterized by the presence of one cell, but in the end of process there exists two identical cells.</span>
