Answer:
the first one
Explanation:
So the predicted offspring genotypes are 50% Hh and 50% hh
so there is a 50% chance that they will have no horns and and aa 50% chance that they wont
Answer:
Glucose
Explanation:
Water is an obvious one. Dissolved in the water are traces of urea. And there are concentrations of sodium. No glucose though.

Answer: Over 4 billion years ago
Explanation: The chemical reactions between carbon and water is said to bring about life according to scientists. These reactions builds largely upon four families of chemicals (lipids, carbohydrates, amino acids, and nucleic acids).
However, the actual time of life on Earth has varying speculations from different scientists in fields of study (such as molecular biology, chemistry, oceanography, etc).
Furthermore, microfossils within hydrothermal-vent precipitates dated from 3.77 to 4.28 billion years is presumed to inhabit the oldest record of life on Earth. Hence, which is presumed to have occurred after ocean formation 4.4billion years ago.
Thus, the actual date of the chemical reactions that brought about life is not rigid, but presumed to have occurred over 4billion years ago (according to research).
The best choice is A.
A gene is a specific sequence of nucleotides in DNA or RNA that is located usually on a chromosome and that specifies the structure of a particular polypeptide and especially a protein, or controls the function of other genetic material.
Information from the gene is copied (transcribed) on mRNA in the nucleus. mRNA then leaves the nucleus and enters the cytoplasm where it attaches to a ribosome. The information on the attached mRNA is decoded (translated) by tRNA which then fetches the amino acids according to this information and brings them to the ribosome where they are linked together to form the specified protein.
