Insect populations can develop resistance to insecticides over time. The evolution of resistance is associated with an increase in the frequency of adaptive genes in the population.
- In the case above described it is expected that a few mosquitoes in the population were resistant to DDT before it was ever used (Option a is correct).
- Dichlorodiphenyltrichloroethane (DDT) is a pesticide used in agriculture.
- After exposure to DDT, those individuals in the mosquito population that didn't carry gene variants (i.e., alleles) associated with the resistance to this pesticide died.
- Subsequently, insects having adaptive alleles associated with DDT resistance survived and reproduced, thereby increasing the frequency of adaptive genes/alleles in the population.

Answer:
Minerals
Explanation:
Gases are natural and in the ground, metals are also in the ground as are non metals -just look at dirt- and minerals are usually found in geodes, which are usually fallen bits of asteroid and meteorite that has survived earth's atmosphere
Answer:
False.
Explanation:
An Haemoglobin molecule is made up of 4-polypeptides, with each of the polypeptide chain containing an haem group. These haem group can bind with one oxygen atom each.
T<u>he binding of the first oxygen atom by the first haem group weakens the tertiary protein structure of Quaternary structure Hb, thus it makes it easier for the second Oxygen atom to bind faster, and the 3rd oxygen very fast and the 4th oxygen atom the fastest.These accelerated binding of the oxygen atoms, facilitated by the first binding O2, is called cooperative binding.It aids oxygen binding capacity and tranport functions of Hb,</u>
<u />
<u>Myoglobin is an oxygen storage protein in muscles, and not oxygen carrying molecule, It releases stored O2 only in condition of low oxygen supply</u>.It has one haem group in its molecule.Therefore its structural features can not carry out cooperative binding.
