Answer:
A
Explanation:
in DNA there is complementary base pairing which is that Adenine always pairs with Thymine and Cytosine always pairs with Guanine. therefore, if there is a certain amount of adenine in the DNA it must have the same amount of its complementary base, thymine.
the answer cannot be b as cytosine and thymine are not complementary base pairs. although b can coincidently be correct- that the amount of cytosine and thymine are equal- the question states that it must always be true. the answer cannot be c as ribose is found in RNA and deoxribose is found in DNA.
Answer :
Vinegar is a weak acid. This is used to make a naked egg. When an egg is added in the vinegar for one day / 24 hrs, it reacts with the eggshell. The calcium carbonate shell gets dissolve.
Then an egg without shell is formed and the size of the egg does not change. The calcium carbonate reacts with acetic acid and forms carbon dioxide.
When the shell-less egg is kept in the vinegar for 48 hrs i.e. 2 days again, the water content in it enters into the eggs through the membrane. Then the egg gets somewhat bigger.
Otherwise, for 24 hrs, vinegar is acting like an isotonic solution and only dissolves the shell. This experiment would be done for showing the osmosis process through the cell membrane.

Explanation:
Selection pressure means factors that contribute to selection which variations will provide the individual with an increase chance of surviving over others. Because of selective pressures, organisms with certain phenotypes have an advantage when it comes to survival and reproduction. Over time, this leads to evolution.
