Answer:
Option A
Explanation:
As per the first equation of equilibrium of Hardy Weinberg, the sum of frequencies of alleles at the locus is equal to unity.
Thus,
If "p" represents the frequency of dominant allele, "q" represents the frequency of recessive allele and at equilibrium
Let us assume that value of q is given in question which is equal to 
On substituting the given values in above equation we get -
Hence, option A is correct
I believe the true statement is the second option
Answer:
Photosynthesis replace CO2 with O2 in the atmosphere. Plants prepare their food by this process.
The burning of hydrocarbon in the presence of O2 is called combustion.
CH4. + O2-----------> CO2. + H2O + Heat
Hydrocarbons undergo combustion.

The questions related to ethics does not requires proper experiment. These questions can be answered based on person's opinion.
Answer:
The correct answers are:
a. both
b. both
c. neither
d. only mitochondrial genomes.
Explanation:
Chloroplast and mitochondria are two organelles that have very similar characteristics and are present in plants and eukaryotic cells, respectively. Among the characteristics that both share are that both contain tRNA genes (which play a pivotal role in the inner organelle functions), both encode proteins that participate in electron transport pathways (since both organelles perform electron transport pathway for cellular respiration) and neither have all the genes necessary for function of the organelle are present (they need genomic DNA for this purpose). On the other hand, only mitochondrial genomes vary greatly in size from organism to organism, since chloroplast genome is very consistent, having 120 to 130 genes in total.
