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:
The sugar and phosphate group make up the backbone of the DNA double helix, while the bases are located in the middle.

Discontinuous variable ;)
Cell theory is one of the foundations of biology. The observation of Robert Hooke,Anton Van Leeuewenhoek,Matthias Schleiden,Theodor Schwann,Rudolf Virchow, and others led to the devolepment of the cell theory.
Answer:
All forms of life employ the same genetic code
Explanation:
The genetic code refers to the set of rules that facilitates the translation of nucleotide sequences into amino acids sequences (proteins). mRNA is read in a group of three nucleotides called CODON, which specifies a particular amino acid. The totality of all codons makes up the genetic code.
However, one of the characteristics of the genetic cos is its UNIVERSAL nature. The genetic code is said to be nearly universal meaning that the genetic code is the same in almost all living organisms with few exceptions. For example, AUG codon encodes Methionine amino acid in all forms of life.
Hence, All forms of life employ the same genetic code is TRUE. Note that, tRNA and rRNA are other types of RNA found in living systems. Also, liver cells are diploid i.e. has two sets of chromosomes. Lastly, interacting organisms affect their environment
