Answer:
B. Genotypes
Explanation:
The genotype of an organism refers to the genetic makeup of that organism. It is the combination of all the genes contained on the chromosomes of that organism. Gregor Mendel, who is considered to be the Father of Genetics, discovered that certain factors are responsible for the physical characteristics of organisms and that they can be transferred from one generation to another. These factors are called GENES. Genes are located on X-shaped structures called chromosomes.
Hence, the isolation of chromosomes taken from tortoise blood samples refers to recording their GENOTYPE (genetic constituent).

Answer:
Plastic and trash bags can be used to generate renewable energy in the following way the mechanism of cold plasma pyrolysis.
Explanation:
- Cold plasma pyrolysis is a method in which chemical compounds like plastic wastes and trash bags are subjected to high temperatures like 400 to 650 degree Celsius under limited oxygen condition.
- The above process generates huge amount of energy in the form of heat that can be converted to usable electricity.
- The process generates compounds like hydrogen, methane and ethylene.
- The hydrogen and methane can be used as clean fuels because they produce minimum harmful components like carbon dioxide and soot on combustion.
- The ethylene is the basic component of plastics and can be reused to produce more plastics.
