Biology MCQs

Notes:
The testes produce testosterone which is responsible for male sexual characteristics.

Notes:
Ovaries release eggs when the luteinizing hormone increases.

Notes:
Mendel is known as the “Father of Genetics”.

Notes:
The term biomass most often refers to Organic matter. Organic material is that was alive and is now in or on the soil.

Notes:
A plasmid is used as a tool to insert genes into bacteria to stimulate the production of therapeutic proteins such as human insulin.

Notes:
The origin of replication is a sequence of DNA on which replication is initiated on a chromosome, plasmid or virus.

Notes:
Protease is an enzyme that cleaves proteins. These enzymes are made by animals, plants, fungi, and bacteria.

Notes:
Coriander (Coriandrum sativum), also known as cilantro, Chinese parsley or dhania, is an annual herb in the family Apiaceae. All parts of the plant are edible, but the fresh leaves and the dried seeds are the parts most traditionally used in cooking.

Notes:
A cross between a homozygous plant with recessive traits and a heterozygous plant is known as a test cross. A test cross is a valuable tool in predicting the genotype of the organism in question. In its simplest form, a test cross is an experimental cross of an individual organism of dominant phenotype but unknown genotype and an organism with a homozygous recessive genotype (and phenotype). Test cross is done to determine the genotype of an F2 generation plant, showing dominant characteristics. In the test cross, an F2 plant that shows the dominant trait is crossed with the homozygous recessive.

Notes:
Animals, such as mammals and birds, that maintain a constant body temperature regardless of the temperature of the surroundings are called warm blooded. These include birds and mammals. Whales are aquatic mammals hence, being mammal, they are warm blooded. The have a thick layer of fats called blubber underneath their skin to maintain temperature even in cold water of oceans.
