Answer:
The answer to your question is 30
Explanation:
DNA is composed of 4 nitrogenous bases: Adenine, Cytosine, Guanine and, Thymine.
These base form pairs, Adenine attach to Thymine and Cytosine attach to Guanine.
If a tiger has 20% Adenine that means it also has 20% of Thymine. Total 40% and the other 60 % are Guanine and Cytosine.
Which means 30% Guanine and 30% Cytosine
Answer: Senescent cells
The Senescence of
the eyes is often demonstrated by the presence of <span>senescence cells. They are forms of cells that are normally capable of
replication within mammalian tissues but permanently non-dividing and
share features with oncogene-induced senescence.
</span>Moreover, the accumulation of senescent cells has been overwhelmingly
studied using fibroblasts and has been proposed to act as an ageing mechanism.
<span>In chemistry, </span>activation energy<span> is a term introduced in 1889 by the Swedish scientist Svante Arrhenius to describe the minimum </span>energy<span> which must be available to a chemical system with potential reactants to result in a chemical reaction. That is the definition of it, but I have no idea what examples you want me to see are called energy of activation</span>
prophase is the phase where centrioles move to opposite poles
