tasks such as walking or chewing are typically controlled ________ , because __________.
Tasks such as walking or chewing are typically controlled automatically because they involve well-learned motor patterns that do not require conscious effort or attention to execute.
The neural control for these activities is primarily governed by the lower levels of the central nervous system, such as the brainstem and spinal cord, which contain circuits known as central pattern generators (CPGs). These CPGs generate rhythmic motor patterns and coordinate muscle contractions involved in repetitive tasks like walking or chewing. As a result, these activities can be performed without conscious thought, allowing individuals to focus on other cognitive tasks or environmental stimuli.
Tasks such as walking or chewing are typically controlled automatically because they have become ingrained motor patterns through practice and repetition. Once these motor patterns are learned, they are stored in the neural circuits of the lower levels of the central nervous system, such as the brainstem and spinal cord.

The addition of folic acid to enriched foods is intended to reduce the ocurrence of:A.) Premature birthsB.) Fetal alcohol syndromeC.) HydrocephalusD.) Neural tube defects
The addition of folic acid to enriched foods is intended to reduce the occurrence of neural tube defects.
The addition of folic acid to enriched foods is primarily intended to reduce the occurrence of neural tube defects (NTDs). Neural tube defects are serious birth defects that affect the development of the brain and spinal cord in the early stages of pregnancy. By supplementing the diet with folic acid, the risk of NTDs such as spina bifida and anencephaly can be significantly reduced.
Folic acid is a synthetic form of folate, a B-vitamin that plays a crucial role in fetal development. Adequate folic acid intake before and during early pregnancy is important because neural tube formation occurs during the first few weeks when many women may not even be aware that they are pregnant.
While folic acid supplementation is beneficial in reducing the occurrence of NTDs, it is not directly associated with reducing premature births, fetal alcohol syndrome, or hydrocephalus. Premature births have various causes, and fetal alcohol syndrome is caused by maternal alcohol consumption during pregnancy. Hydrocephalus, on the other hand, is a condition characterized by an accumulation of cerebrospinal fluid in the brain and is not directly linked to folic acid intake.

the type of anemia caused by a failure of the bone marrow to produce red blood cells is
The type of anemia caused by a failure of the bone marrow to produce red blood cells is aplastic anemia.
The aplastic anemia is a rare but serious condition characterized by a failure of the bone marrow to produce an adequate number of red blood cells, white blood cells, and platelets. It can occur due to various causes, including autoimmune disorders, viral infections, exposure to certain medications or toxins, and inherited conditions. In aplastic anemia, the bone marrow becomes aplastic or hypoplastic, meaning it fails to produce enough healthy blood cells.
The reduction in red blood cell production leads to a decrease in the number of circulating red blood cells, resulting in anemia. This can lead to symptoms such as fatigue, weakness, shortness of breath, pale skin, and rapid heartbeat. Additionally, the decreased production of white blood cells and platelets can lead to an increased risk of infections and bleeding tendencies.
Diagnosis of aplastic anemia involves a thorough medical history, physical examination, blood tests to assess blood cell counts and other parameters, and a bone marrow biopsy to evaluate the bone marrow's function and cellularity. Treatment options for aplastic anemia may include blood transfusions, medications to stimulate bone marrow function, immunosuppressive therapy, and in severe cases, bone marrow transplantation.
