Answer: A) Fetal waste is removed through the chorion; infant waste is removed through the rectum.
Explanation:
A developing fetus is surrounded by chorion which is an outer membrane. The role of the chorion is to protect the embryo and provide nutrition to it in the form of blood supply. It helps in getting rid of waste products from the developing fetus that goes into the mother blood to remove out of her body. In case of infants the rectum is the last part of the digestive tract and it receives the waste in the form of fecal matter from small intestine which is removed out through the rectum.
Answer:
A flexible connective tissue, known as cartilage varies from bones in many ways, its microcomposition is less developed in comparison to the bone and is avascular. It is not supplied with nerves and thus depends upon the process of diffusion to attain nutrients. The three kinds of cartilage are fibrous, hyaline, and elastic.
Of these the most widespread kind is the hyaline cartilage, it looks like glass. It is witnessed in embryos, where the formation of bone takes place as hyaline cartilage, which ossifies later. In adults, it is found on the tips of the ribs, on the articular surfaces of the long bones, the parts of the skull, and the rings of the trachea.
Fibrous cartilage is witnessed in the pubic symphysis and intervertebral discs and exhibits many collagen fibers.
Elastic cartilage is witnessed in the internal support of the external ear and the epiglottis and is yellow, springy, and elastic in characteristics.

Answer
It takes longer time for fructose to be absorbed un human body's small intestine as compared to other monosaccharides.
Explanation
A human body takes fructose in the form sucrose present in fruits or vegetable, it break up into glucose and fructose with the heip of sucrase enzyme.
Absorption in small intestine
Fructose is absorbed in samll intestine join blood stream, travel along other nutrients towards liver for further metabolism ans processing.
Metabolism in liver
Once it reach to liver here and enzyme known as aldolase beta help in the metabolism of fructose. the last products of metabolized fructose are now same other monosaccharides and enter to glycolysis either through aerobic or anaerobic respiration.
In case of glucose
Glucose absorption and metabolism is not much difficult as compared to fructose, because it is directly absorbed in blood stream from small intestine and reach to those cells where it it needed for respiration (energy production).
