Answer:
Genes are made of DNA and are carried on chromosomes
Explanation:
When a cell makes a protein the instructions are copied from part of the DNA strand and transcribed to new molecule, called RNA. RNA molecules carry the instruction from the nucleus to ribosomes.
The rescue workers can get energy to the batteries in their equipment during rescue missions by using a generator to convert the kinetic energy to potential energy. Potential energy is then stored in the battery.
The answer is D. The natural selection is a theory which illustrates the gradual process of evolution in the population due to the change of environment. The key point is the mutation (variation) exists in the population before the environment changing. For C, if the environment does not change, though the adaptation is useful to environment, it will not be selected. Because the organisms without the adaptation will not die.
