Explanation:
A sugar is a source of carbohydrate which is made up of carbon and oxygen atoms. Providing a yeast with more amount of sugar will increase the process of fermentation which is the anaerobic respiration. The carbon dioxide will be released after this process. The released carbon dioxide gas can be measured by observing the shape of the balloon and measuring the quantity of carbon dioxide present in the balloon.
The correct answer is option A, It grows healthy crops.
Because the loess soil is very fertile due to its ability to exchange cations and porosity.
Due to cation exchange capacity the plants easily absorbs nutrients from the soil and due to porosity the soil holds the water, oxygen and nutrients which is absorbed by the roots of the plants for their nourishment.
Answer:
19.32 m²
Explanation:
The area of a living room is the product of its length and breadth. The area is given by:
Area = length × breadth
1 meter = 3.28 feet. Hence:
Length = 16 ft
16 ft = 
Breadth = 13 ft
13 ft = 
Area = length × breadth = 4.88 m × 3.96 m = 19.32 m²
Hence 19.32 m² of carpet is needed for the living room

1) The correct answer is: 128 combinations.
The genetic combinations that are possible through independent assortment can be calculated as 2^n; where n is the number of different chromosomes.
So, using this formula for 7 chromosomes:
2^7 = 128 different combinations.
2) For a zygote produced by two barley parents, the number of possible genetic combinations can be calculated as: 2^n * 2^n
So, for 7 chromosomes: 2^7 * 2^7=16384
