I hope that's help !
B. The genetic offspring are exactly like the parent cell.
C. There are 23 chromosomes from each parent cell passed on to the offspring.
D. Meiosis goes through 2 stages of division, Meiosis I and II.
Answer:
I would say it is B.
Explanation:
In Meiosis, specifically in Prophase 1, it creates genetic variation. Crossing over occurs in that stage
b)Viruses produce cells.
c)Viruses are made of DNA and proteins, but not cells.
d)Viruses attack cells and are dangerous to them.
Answer:
C
Explanation:
Hope this helps :)
Ans.
Protein synthesis involves two stages, named as transcription and translation. During transcription, information present in DNA molecule is used to make mRNA molecule, while translation involves formation of polypeptide chain or protein by using information present in mRNA in the form of codons.
Prokaryotic organisms lake true nuclei, hence in these organisms both transcription and translation take place in cytosol. In eukaryotic organisms, transcription takes place in nucleus, while translation takes place in ribosomes, present in the cytosol.
A.skin
B.rigid tubes
C.exoskeleton
D.other muscles
Unlike humans, whose bones and muscles help them to move, in insects the structure that protects them and also provides them the structure is called an exoskeleton.
Insects are referred to as invertebrates, unlike mammals. This states that insects tend to lack an internal skeleton. Instead of an internal skeleton, the insects possess an exoskeleton that is specifically situated external side of their bodies. The exoskeleton is useful in the following ways:
Thus, we can conclude that the exoskeleton is the insect’s structure that helps in protecting them and further provides them the structure. Hence, the correct answer is option C.
