7.5 too, its kinda of ratio, 1cm : 1Km to 7.5cm : x
x will be equal 7.5 km
Answer:
A). True
Explanation:
tRNA, which means transfer RNA is one of the three types of RNA known in nature. The tRNA is found in the ribosome, where it plays a pivotal role in protein synthesis (translation). Transfer RNA is the RNA responsible for reading the nucleotides in the mRNA codon and carrying the amino acid that corresponds those codons to the ribosome.
The tRNA has a 3-dimensional structure that allows it to carry anticodon that reads codon and also carry amino acids on opposite ends. Hence, according to this question, tRNA is a type of RNA that delivers amino acids to the ribosome during protein synthesis.
Answer:
Option B
Explanation:
B. The cell will grow uncontrollably and continue to divide as long as it has food.
Cell growth is theeoretically stimulated by the binding of growth factors to their receptors using signaling pathways.
These pathways are regulated by proteins which are encoded for in the genes.
The gene that controls the regulation of these pathway when mutated produce malfunctioning signaling protein thus not allow for regulations of the cell cycle causing uncontrollable cell division. These mutated genes are called oncogenes.
I think it is called mechanical digestion. Or alas, chemical digestion. One of those. Or both!

Answer: the correct answer is d. all of the above must happen for defecation to occur.
Explanation:
In response to the distention of the rectal wall, the receptors send sensory nerve impulses to the sacral spinal cord. Motor impulses from the cord travel along parasympathetic nerves back to the descending colon, sigmoid colon, rectum, and anus. The resulting contraction of the longitudinal rectal muscles shortens the rectum, thereby increasing the pressure within it. This then opens the internal sphincter.
