Answer:
Amino acids.
Explanation:
Miller -Urey experiment was performed by creating the primitive earth condition in the laboratory. The main aim of this test was to determine the chemical origin of the life.
The electrodes was used to create the spark conditions and different gases like water, methane, ammonia, and hydrogen. The product was obtained after some days of the reaction. The amino acids like glutamic acid, glycine, α-alanine and β-alanine was obtained from the product of this experiment.
Thus, the correct answer is option (1).
Answer: reproduction, heredity, variation in physical characteristics and variation in number of offspring per individual.
Explanation:
It is true that inheritance of mutant forms of certain genes
might lead to a predisposition to develop cancer. This notwithstanding, the DS
Cell Adhesion Molecule gene (DScam gene) has not in any way been linked to
hereditary forms of cancer.
Answer:
True.
Explanation:
Prokaryotes and eukaryotes shows various similarities as well as differences among themselves. The eukaryotes have well defined nucleus whereas such nucleus is absent in prokaryotes.
Prokaryotes are much smaller in size than eukaryotic cells. The small area has large surface area to volume ratio. This ration helps in the process of diffusion and metabolism in prokaryotes. Due to their small size, prokaryotes have large surface area to volume ratio than eukaryotic cells.
Thus, the correct answer is option (a).
