Each chromosome (replicated or not) contains 2 chromatids.
<u>Answer:</u> Mutations are the most fundamental way to add new genes to a gene pool.
<u>Explanation:</u>
Mutation refers to the process through which the normal sequence of altered. It may be either acquired or hereditary. It leads to addition of new genes to a gene pool.
The reason for not considering other statements as true are:
1. It is the hereditary mutation that are passed form parent to offspring's and acquired mutation is caused by external factors.
2. Acquired mutation are caused by external factors such as radiation.
3. Germ line mutation are important to evolution because they can be inherited.
Answer:B) protein
Explanation: Protein is the biomolecule synthesized in the ribosome. Protein is synthesized in a process known as translation in which the message encoded in an mRNA is translated into a polypeptide chain of a specific amino acid sequence in the ribosome. The polypeptide chain is then packaged in to protein through posttranslational modifications.
Looking at the inside, it appears so.
In telophase, the cell is nearly done dividing, and it starts to re-establish its normal structures as cytokinesis (division of the cell contents) takes place.
Hope this is correct ^^
