Traumatic brain injury is usually caused by a blow or other traumatic injury to the head or body. The degree of damage can depend on several factors, including the nature of the injury and the force of impact. Common events causing traumatic brain injury include the following: Falls.
The question is incomplete. The correct question is as following:
__________ studied the role of RNA in protein synthesis, specifically in the bacteria E. coli.
Answer:
Marshall Nirenberg and Heinrich Matthaei
Explanation:
Marshall Nirenberg and Heinrich Matthaei are two biochemist and geneticist who studied the functional importance of RNA in the process of translation (protein synthesis) experimentally in E.Coli.
Nirenberg and Matthaei discovered the first codon out of 64 codons present in RNA and they successfully performed translation (protein synthesis) in E.coli in a test tube. They decoded the first codon UUU (phenylalanine) by using synthetic RNA having only uracil nucleotides in a E.Coli and later they decoded further codons.
So, the correct answer is Marshall Nirenberg and Heinrich Matthaei.
Hey Taonga! Tropism involves an organism (mainly plant) growing toward or away from a stimulus. Taxis involves an organism (protist or animal) moving toward a stimulus.
The correct answer is C. She added water that was hypotonic to the culture of organisms, and they ruptured.
Explanation:
In biology, a hypotonic solution is a substance with less concentration than the inner concentration in cells, this is the opposite of a hypertonic solution that has a higher concentration. Additionally, if cells are in hypotonic solution water or liquid will begin to get into them and this would make cells burst and finally explode and die due to the pressure in them.
This occurred in the case presented as it is likely the organisms collected from the ocean had a high concentration and therefore hen they were exposed to clean water in which concentration was lower, water entered into the cells and made them explode, which explains the only remains of them were bit and pieces.
