Answer:
1. B. carbon dioxide taken in from the surrounding air
2. A. Root
Explanation:
Sugar beet plant carries out photosynthesis and stores the excess of the sucrose in its taproots. During the process of photosynthesis, the plant absorbs CO2 from the air, water from the soil and synthesizes organic sugars in the presence of sunlight.
Atmospheric CO2 contributes carbon and oxygen atoms to the formed sugars which in turn are stored in plant parts. Therefore, atmospheric CO2 makes most of the mass of the photosynthesizing plants such as sugar beets. The taproots of beet plants are modified into storage roots to store the excess of the organic sugars.
Answer:
Option C
Explanation:
Given ,
A1 allele is carried by 
% people
Let us assume A1 s dominant genotype
This means 
Thus, frequency of allele in the given population is 
It is also given that the population is in Hardy-Weinberg equilibrium thus
Frequency of fruit fly with genotype A2A2 will be
As per Hardy-Weinberg's second equation of equilibrium
Hence, option C is correct
That is because all meridians start and end at the same point, unlike parallels that are parallel. Meridians all start at the north pole and go towards the south. Therefore, all of them meet at that point that is the north pole, so the distance between all of them is 0 miles.
Direct characterizaation is what the author says about the character.
So B would be correct
