Answer:
The correct answer is a. absent spinal reflexes below the level of injury.
Explanation:
Spinal shock strictly refers to the neurological condition that occurs immediately after a spinal cord injury, in which the loss of not only motor and sensory functions occurs, but also the abolition of all reflexes below the injury (reflexes of muscular or myotatic stretching and cutaneous reflexes). There is also flaccidity, loss of reflexes. It is characterized by hypotension associated with cervical or upper thoracic spinal injuries. This characteristic shock results from the lesion of the descending sympathetic pathway in the spinal cord, producing a loss of vasomotor tone and sympathetic innervation of the heart. This causes vasodilation of the affected area with accumulation of blood and a decrease in venous return to the heart as well as cardiac output.
Answer:
A zinc finger is also known as zinc-binding repeats or ZnF that are molecular scaffold which is characterized by the coordination of Zn²⁺ ions so it can stabilize the fold.
The zinc fingers consist of several amino acid sequence 2 histidine and 2 cysteine residues at intervals. These residues bind to the zinc atom covalently and form finger-like motifs.
They are a major family of eukaryotic transcription factors. These are identified in a significant regulatory state such as developmental control genes and proto-oncogene by binding to the DNA, RNA, or protein.

Answer:
The correct answer is embroynic stage
Explanation:
The prenatal development is divided into three stages germinal stage, embryonic stage and fetal stage. The period of two weeks after fertilization is called the germinal stage. In this stage, the zygote divided and gets implanted in the uterine wall.
The embryonic stage starts for two weeks and lasts up to 8 weeks after fertilization. At this stage, the cell mass is called embryo. In the embryonic stage, the basic brain structure, CNS, PNS are developed. All the basic organs and body parts develop in this stage except sex organs. So the right answer is the embryonic stage.
