Answer:
The most common myths are:
- C0vid2019 vaccines cause autism
- C0vid2019 vaccines may modify your DNA
- C0vid2019 vaccines are unsafe
Explanation:
The most common myths associated with C0vid2019 vaccines are:
1- C0vid2019 vaccines may cause autism: In 1998, Andrew Wakefield and colleagues published a controversial study in the Lancet where they suggested that the measles, mumps, and rubella (MMR) vaccine may cause autism in some children. However, it has been showed that this study was based on erroneous statements and therefore this publication was retracted.
2- C0vid2019 vaccine may modify your DNA: it has been suggested that vaccines based on viral vectors (e.g. adenoviruses) and mRNA vaccines may modify the DNA of cells. This statement is false because these technologies cannot alter the DNA sequence. These vaccines are based on the production of an mRNA sequence that is translated into a viral protein (spike protein) which triggers an immune response
- C0vid2019 vaccines are unsafe: some people believe that C0vid2019 vaccines are unsafe because they were developed quickly. However, this statement is false because all vaccines (including C0vid2019 vaccines) need to follow rigorous safety standards to be approved by governmental agencies (i.e., they approved all clinical trials).
The pentose sugar on RNA is called ribose. (a trick to remember it is that the "R" in RNA stands for ribo)

Answer: b
Explanation: Mitosis produces 2 cells where has meiosis produces 4 and 2 is half of 4
(plus I just took a test with this question)
The decline in bone breakdown and increased mineralization causes blood calcium to decrease <span>back to normal levels. This happens when there is secretion of calcitonin. This circulation calcitonin is inhibiting </span>osteoclasts<span> and it will stimulate osteoblasts within minutes. The effect of this on osteoclast will cause a decrease in reabsorption and a concurrent increase in deposition because of the osteoblasts activity.</span>
