The primary ethical guidelines that apply to this experiment are those of human experimentation.
The use of humans as subjects of experimentation would seem to demean their human dignity. The issue of abuse of the human subjects and also the prospects of the clinical trial going wrong (such as causing an adverse effect on the subjects) also raise ethical challenges even when the subjects are volunteers. In case of a clinical error, what is the right compensation?
Explanation:
Stratified cuboidal epithelium and stratified columnar epithelium can also be found in certain glands and ducts, but are uncommon in the human body.
Answer:
Examples of abiotic factors are water, air, soil, sunlight, and minerals. Biotic factors are living or once-living organisms in the ecosystem. These are obtained from the biosphere and are capable of reproduction. Examples of biotic factors are animals, birds, plants, fungi, and other similar organisms.
Answer: Valves in the veins
Explanation: The flow of the blood inside the body takes place through the veins and arteries. The oxygenated blood from the heart is supplied to the different parts of the body.
The blood flows from the capillaries to the venules and from there to the veins. The blood moves in the veins by the rhythmic movement of the smooth muscles in the body.
Most of the blood moves against the gravity so there is a chance that it can backflow so to prevent this there are valves in the veins known as one way valves.
The answer is C because more cells= more specialization
