Human males possess an XY pairing.
Answer: 3- mutation, natural selection, migration
Explanation:
1-genetic drift, mutation, natural selection
2-mutation, founder principle, bottleneck effect
3-mutation, natural selection, migration (gene flow)
The correct answer for this question is" #3.mutation, natural selection, migration (gene flow)." The sequence of evolutionary mechanisms which have come into effect in each event is that of mutation, natural selection and migration. There is a steady rise in the population of bright-colored fish. Both populations thrive.
Answer:
1. RNA polymerase binds to the promoter.
2. DNA strands are unwound and separated
3. The complementary RNA nucleotides are added.
Take a look at the attached picture. First, the RNA polymerase must bind to the promoter region to initiate the whole process. DNA must be unwound by DNA helicase, then it will make the RNA transcript, which consists of adding the complementary RNA nucleotides to the DNA strand. Then the transcript leaves the nucleus and begins translation.
Answer:
C.22 grams because mass cannot be created or destroyed
Explanation:
Reaction equation:
2H₂ + O₂ → 2 H₂O
Mass of oxygen = 18g
Mass of hydrogen = 4g
The mass of water produced is 22g according to law of conservation of mass.
The law states that " in a chemical reaction, mass is always conserved"
The sum of the mass of product and reactants must always be the same.
