Deoxyribose sugar and phosphate group
Are nucleotides
The right answer is They compare quantities for particular categories.
The bar graph is composed of horizontal bands. The categories are presented on the ordinate (Y axis - vertical). The length of each bar is measured by the values arranged on the abscissa (X axis - horizontal).
It draws attention to the comparison of values rather than a period followed by time (as in the case of the bar chart).
Answer:
They are organisms (individual organisms called "plankters") that live in large bodies of water.
Explanation:
They reside in large bodies of water (oceans, lakes, etc). They are usually abundant in surface waters because all ecosystems of plankton live off input of solar energy.
Answer:
Yes.
Probability of such child = 1/2 or 50%
Explanation:
According to the question, below are the genotypes and phenotypes possibilities:
aa = normal vision & no headache
Aa = normal vision & no headache
AA = blindness & headache
Male Female
Aa aa
Possible genotypes of progeny: Aa Aa aa aa
So it is clear that out of the 4 probable children, 2 with 'genotype aa' will have normal vision & no headache.
Mathematical expression is as under:
2/4 = 1/2 that means 50% progeny.
