Answer:
4. cannot be made by the body and therefore must be consumed to maintain health.
Explanation:
Essential nutrients are nutrients that our body cannot synthesized and also those nutrients our body cannot produced in sufficient quantity, for the normal functioning of the body. These nutrients have to be obtained from the food we consume to support our life and health.
Essential nutrients obtained from food include carbohydrates, fats and oils, proteins, water, as well as certain vitamins and minerals. These essential nutrients that we get from our food are needed for good growth and development, prevention of diseases, as well as for maintaining good health.
D) The AV valves are supported by chordae tendineae so that they do not blow back up into the atria during ventricular contraction.
Answer: Divergence evolution or divergent selection
Explanation:
The divergent evolution/divergent selection can be defined as the process of accumulation of differences between the related populations lies within the species. This process leads to speciation.
This occurs when the two populations of the same species get separated by a geographic barrier. The separated members of the same species experience different selective pressure that are responsible for adaptation in the new environment.
The answer is; anaphase
Cytokinesis is the process in which the mother cell divides into daughter cells. This begins with the partitioning of the cytoplasm, then the cell membrane. During anaphase, the chromosomes are moved towards different poles of the cells using spindle fibers. Cytokinesis also begins in this phase and ends during telophase.
<span>the bones of fibrous joints are joined by fibrous tissue, such as the sutures in the skull or the pelvis. Fibrous joints allow no movement at all. he bones of synovial joints meet in a joint capsule, such as the knee joint where the femur and tibia meet. These joints are the most common and most moveable joints in the human body</span>
