It is b . Because three of them are less than 90.
Answer:
0.2Hz
Explanation:
The wavelength of a radiowave can be calculated this;
λ = v/f
Where;
λ = Wavelength (m)
v = speed (m/s)
f = frequency (Hz)
Based on the information provided in this question, λ = 1.5 x 10^9 meters, c = 3 × 10^8m/s, f = ?
Hence, using λ = v/f
f = v/λ
f = 3 × 10^8 ÷ 1.5 x 10^9
f = 2 × 10^(8-9)
f = 2 × 10^-1
f = 0.2Hz
Telomerase is found in fetal tissues, adult germ cells, and also tumor cells. Telomerase activity is regulated during development and has a very low, almost undetectable activity in somatic (body) cells. Because these somatic cells do not regularly use telomerase, they age.
The Answer is B) Bilateral Symmetry
Answer:
Primase
Explanation:
Primer needed to initiate DNA replication is PRIMASE.
It aids replication by ensuring that a short stretch of nucleic acid are usually complementary to the template which aids the process.
It also helps to provides and make readily available the 3' end for DNA polymerase to work on during the process of replication
