Somatic mutations are important to the evolutionary process; most cancers result from somatic mutations : True
What is somatic mutations?
Any mutation that happens in a cell other than a gamete, germ cell, or gametocyte is referred to as a somatic mutation because it involves a change in the DNA sequence of a somatic cell of a multicellular organism with dedicated reproductive cells. Somatic mutations are typically not passed on to descendants, in contrast to germline mutations, which can be transmitted to an organism's offspring. Plants, which lack a separate germline, and animals that can reproduce asexually by processes like budding, as in the case of members of the cnidarian genus Hydra, obfuscate this distinction.
The descendants of a cell inside the same organism will all carry somatic mutations, even if somatic mutations are not passed on to an organism's progeny.

Answer:
The answer to the question: What do you view as important issues within healthcare delivery, would be: the availability of more and better resources to ensure that all patients are treated with efficiency and effectiveness, depending on their individual needs, and the possibility to have more, and better-prepared office staff, like secretaries and receptionists, so that healthcare providers can focus entirely on patient care, and not on the mountains of paperwork, phone calls and documentation that insurance companies require to authorize a simple procedure that would improve a patient´s life.
Explanation:
Although there are a lot more issues that need to be addressed regarding patient care delivery, these two have proven to become real obstacles. First, although some hospitals and clinics are blessed with resources, this is not always the case, especially for public hospitals. The result of this is that patients at public hospitals are not always given the best care that could be given to them due to lack of resources and this lowers the efficiency of healthcare. The second issue is that healthcare professionals are becoming encumbered more and more with the amount of paperwork and documentation that is demanded by insurance companies simply to authorize the payment of a procedure. This also limits the effectiveness of treatment, as healthcare professionals do not have access to all the resources that are available to ensure the best treatment. This is why, to me, these two are some of the most important issues to face right now.
Answer:
The chyme, which is already a fecal bolus formed produces an involuntary stimulus reaching the colon that cause the defecation; The first step is the relaxation of the internal sphincter through the sacral nerve (involuntary), and then voluntarily the cerebral cortex through the pudendal nerves that relax the external sphincter.

Answer:
(D). cesarean section
Explanation:
Oxytocin is a peptide hormone, synthesized by hypothalamus and secreted by posterior pituitary. Oxytocin plays role in sexual reproduction, lactation, and induce contractions during child birth.
Oxytocin is naturally produced at the time of child birth, but natural oxytocin has a short half-life. Hence, oxytocin infusion is done during child birth or cesarean section as it maintains contraction of uterine wall during the surgery.
Thus, the correct answer is option (D).
