8 0

Answer:

C) They have similar antibiotic sensitivities to those of bacteria.

Explanation:

  • Ribosomes are the site for biological protein synthesis that is composed of macromolecular machine for protein synthesis.
  • In archaea they ribosomes comprise of three RNA molecules - 16S, 23S, and 5S.
  • The archaeal ribosome is a 70S ribosome that is composed of 50S and 30 S subunits.
  • The ribosomal binding site of archaeol ribosome may be similar to that of the bacteria, i.e. the Shine- Dalgarno sequence.
  • <em>However, the antibiotic sensitivity of the archaeal ribosome is different than those of bacteria as the r-protein sequence of the archaea are closer to that of eukaryote than the bacteria. </em>

An oil spill happened at the Wild Harbor salt marsh on Cape Cod, Massachusetts in 1969. The oil has persisted in the ground sinc
Dima020 [189]
I would guess that the answer would be :'<span>These organisms dig more shallow burrows than they used to.</span>' If the crabs actively dig burrows, as many crab species do, and a layer of oil has persisted in the lower soil strata, it makes sense that the crabs would be reducing the depths of their burrows to avoid contact with the oil. The other possibility is that the crabs might might migrate to deeper waters, but this is less likely because the crabs would be evolved to utilise the intertidal zone.

The stage of spinal shock that follows spinal cord injury is characterized by a. absent spinal reflexes below the level of injur
IrinaVladis [17]

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.
