devlian [24]
The correct answer is oviduct.

<span>When oocyte (female gamete) is released from the ovary during the ovulation, it travels down the fallopian tube (uterine tubes or oviduct) into the uterus, where it may become fertilised by a sperm. If fertilisation does not occur, the uterine wall and blood will be shed during menstruation.</span>

Identify the locations within the human body for Hyaline, Elastic and Fibrocartilage.
belka [17]

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.

Researchers identify a gene in cockroaches that is responsible for their ability of nerve regeneration. How might it be possible
natulia [17]

This gene could be analyzed to determine its homology level with a human gene, which then could be restored in its normal expression. This strategy can restore the normal phenotype in defective human cells.

Sequence homology, which refers to the level of evolutionary relationship among genetic or proteins sequences, is a fundamental subject matter to determine gene function.

From this approach (sequence homology search), researchers can identify valuable genes involved in diseases in which the restoration of their normal expression levels can be used to restore the normal phenotype in defective cells.

In this case, the identification of a gene in cockroaches that is responsible for nerve regeneration could be used for subsequent identification of a human homologous gene sequence, which then can be restored in order to treat human paralysis.
