Answer:
1. Nucleus
2. RNA polymerase
3. mRNA
Explanation:
Transcription is the first process of gene expression in which a DNA strand is used to synthesize a mRNA molecule. In the process of transcription, which occurs in the NUCLEUS, an enzyme called RNA polymerase binds to the DNA molecule.
The enzyme separates the double stranded DNA and the uses the complementary base pairing rule i.e. A-U, G-C to synthesize a mRNA molecule that is complementary to the DNA template strand. This newly built mRNA molecule then leaves the nucleus and enters the cytoplasm of the cell for translation to occur.
Answer:
Insular cortex
Explanation:
The insular cortex is found in the visceral sensory area and receives sensory input from the thalamus to the CNS. They play a role in emotions including self awareness, motor control etc and they also play a part in the regulation of the body's homeostasis.
The answer to your question is A., as the random movement is a movement
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.
