Answer:
A <u><em>receptor</em></u> is a protein that recognizes and responds to a signal.
Explanation:
A receptor is a protein molecule present on the cells on which the signalling molecules can bind and generate a physiological response. Some receptor molecules can also respond to Sun and light. Each type of cell has specific receptors molecules and hence can respond to specific signals. The receptor molecules hence tend to receive signals for a cell. Molecules such as hormones bind to the receptors.
Answer:
mRNA interacts with ribosomes in the cytoplasm.
Explanation:
<em>The correct option would be that mRNA interacts with ribosomes in the cytoplasm.</em>
Translation involves the use of genetic codes in mRNA to synthesize amino acids that are eventually linked together by polypeptide bonds to form proteins.
<u>During translation, the mRNA synthesized in the nucleus is transported into the cytoplasm where it gets attached to the ribosome and another RNA - the tRNA. The codons on the mRNA eventually match with the anticodon of the tRNA with the later releasing the amino acid that corresponds to each codon</u>.
Hence, the correct answer out of all the options is that mRNA interacts with ribosomes in the cytoplasm.
Answer:
Option A
Explanation:
Corona is defined by the strong magnetic fields. When these strong magnetic fields confine solar atmosphere and produces violent bubble of gases then it is said to cause coronal mass ejection (CME).
When a CME passes through the solar wind, it causes production of high velocity solar energetic particles that follow magnetic field lines and passes through the space between the Sun and the Earth. The charged particle added by CME intensifies the solar wind.
Hence, option A is correct
Answer:
Explanation:
Scientific theory: a well established, highly reliable explanation
Scientific hypothesis: makes predictions of future events/
Both: based on observations of natural phenomenons/ can be tested by many researchers
Answer:
the best answer is b.) because they are not manufactured by the body
hope this helps and I'm bored
