The correct answer is the last option: all of the above. The ethical concerns regarding genetic engineering are the privacy of the genetically tested individuals, the unnatural and potentially dangerous organisms being created, and the long-term effects of genetically engineered foods.

Answer:
is a thick band of neural fibers enabling communication between the two brain hemispheres.
Explanation:
A brain can be defined as an organ of soft nerve tissue that is found in the skull of vertebrates and it's typically responsible for the coordination of nervous activities, intellect and sensation.
The human brain consists of various sections and these includes;
I. Anterior Cingulate Cortex (ACC) which resembles a bow or collar surrounding the frontal part of the corpus callosum. This is the frontal part of the cingulate cortex which helps to make complex cognitive functions such as impulse control, decision-making, emotions and empathy.
II. Ventral prefrontal cortex in humans are interconnected with the brain and are responsible for the processing of risk, empathy, fear and social decision-making
III. The Cerebral Cortex: this part of the brain primarily comprises of grey matter, foldable sheets of neurons and forms its outermost layer. Therefore, cerebral cortex is known as the outermost layer of the brain (cerebrum) and thus, makes up half of its weight. It is about 2.5 millimeters in thickness and as such it's able to fold.
The corpus callosum is a large, thick band of C-shaped neural fibers found beneath the cerebral cortex and it's saddled with the responsibility of enabling communication between the two brain hemispheres i.e the right hemisphere and the left hemisphere.
The two cells that result from a single cell need to have the same amount of genetic material as the initial cell, therefore the DNA needs to be duplicated before the cell divides.
The sister chromatids are attached together so that during anaphase the daugther cells will receive the same chromosomes
It would be most important for Eric to find out his <em>zinc, iron and vitamin B12 (or riboflavin) levels, and ensure that he is obtaining adequate amounts of these vitamins and minerals through vegetarian sources </em>.
A vegetarian diet is typically low in zinc rich foods, since meat, shell fish and eggs are the most abundant sources of zinc. In order to ensure that he obtains sufficient zinc, Eric should make sure he consumes vegetarian zinc sources such as legumes, lentils, dairy, nuts and seeds on a daily basis.
Since iron and vitamin B12 are also difficult to obtain from vegetarian sources, Eric should consume iron rich foods such as spinach, kale, whole grains, broccoli, legumes,etc., on a daily basis. As for vitamin B12, daily supplementation of 2.4 μg is recommended for vegetarians. Alternatively, riboflavin fortified cereals and grains are also recommended to meet daily riboflavin requirements.
