The answer to this question may be the second one," Mitosis produces two genetically identical daughter cells but meiosis produces four genetically different daughter cells."
Answer:
miR-223 inhibits the expression of the fibroblast growth factor (bFGF) gene, and thereby ESCs cells maintain their undifferentiated state
.
Explanation:
Non-coding RNA (ncRNAs) are molecules that regulate gene expression, thereby playing important biological functions in cell differentiation, cell cycle, apoptosis, etc. MicroRNAs (miRNAs) are a type of ncRNAs capable of controlling gene expression patterns by regulating mRNA stability and by suppressing their translation into proteins. It has been shown that miRNAs function by imperfectly base-pairing with the 3′ UTR of target mRNAs (Pillai et al. 2005).

Answer:
The Peppered Moth is an example of evolution in action
Explanation:
Answer:
5] Neutron: Charge= 0 Atomic mass unit = 1
10] <u>Hydrogen:</u>
Number of protons = 1
Number of neutrons = 0
Number of electrons = 1
Atomic number = 1
<u>Helium:</u>
Number of protons = 2
Number of neutrons = 2
Number of electrons = 2
Atomic number = 2
<em>Note:</em>
<em>Atomic number = proton number</em>
<em>Neutron number = Mass number - atomic number</em>
<em>Number of electrons = number of protons</em>
