Answer:
Option C
Explanation:
Miller and Urey performed an experiment, using some inorganic molecules such as water, methane, carbon dioxide and hydrogen in laboratories conditions similar to early earth conditions .
Amino acids molecules formed as the result of this experiment, this proved that small organic molecules such as amino acids are formed from inorganic molecules.
Hence, the correct answer is option C
Answer:
The correct answer will be option-B.
Explanation:
Deoxyribose nucleic acid or DNA is the genetic material of the organism which is made up of nucleotide monomer. The structure of DNA is made up of two strands of nucleotides coiled in a helical structure thus providing a double-helical shape to the structure.
Each nucleotide of a strand is composed of a five-carbon sugar, phosphate group and nitrogenous bases. These molecules are arranged in anti-parallel fashion in DNA which provides the polarity to the DNA strand. One strand is read from the 5' to 3' direction whereas another form 3'to 5' direction.
Thus, Option-B is the correct answer.
The reptile produce few offsprings having no unique traits, and the vegetation as well changes quickly so that it can be protected from the reptile species.
Explanation:
Majority of the reptiles lay eggs or give birth to young ones such as squamates , this is done in two ways such as by keeping the egg inside the body of the mother or by developing offsprings without any formation of eggs. Climate change is having an adverse effect on the reptiles , a physiological as well as ecological change is occurring as a result reptiles as well as other species are in danger. Climate change is having an adverse effect on snakes , that is, there is fall in range size of snakes.
