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.
Telophase is the last stage in meitosis before cytokinesis
Answer: Meiosis is the necessary process for the inherited traits of an organism to be passed along by sexual reproduction to bring about variation.
Explanation: Meiosis occurs in reproductive cells. It halves the chromosome number of parents to produce same (constant) number of chromosomes in the offsprings.
Meiosis leads to genetic variation among offsprings through recombination, crossing over, independent assortment and reduction and fusion of gametes.
Most abnormalities that are heritable are as a result of improper division during meiosis.
B. Cyclones is the correct answer because super cells are clouds, as well as wall clouds, and a vortex is another, less powerful tornado.
