Answer:
Option B, It was made in stars that lived before the solar system formed.
Explanation:
Almost all the carbon that exists today with in the living organisms was produced in the stars. When these stars exploded during the big bang theory all the carbon within hem was introduced in the environment of earth some billions of years ago. Hence , though carbon introduced in earth’s environment was due to big bang, its origin is from the stars. Hence option B is the correct answer
Cyanobacteria is responsible for generation of oxygen on planet earth and thus option D is in correct.
The hypothetical cell will approximately contain 94 percent (94%) of water.
- If a cell is placed in a hypertonic solution that contains more concentration of solutes (such as salt and glucose) than the cell, then it will shrink because water moves outside the cell.
- If a cell is placed in a hypotonic solution that contains more concentration of water than the cell, then the water will move inside the cell.
- Finally, if a cell is placed in an isotonic solution, which contains the same concentration of solute and solvent as outside the cell, there will be no change in the cell and the solution.
- In this case, the percentage of solutes is equal to 5% (glucose) + 1% (salt) = 6%, so the remmaining porcentage of water is equal to 94 percent (94%).

Answer – The force of gravity is
stronger than the force of magnetism.
The attractive force of magnetism
is the force that keeps the nails joined to one another and to the end of a bar
magnet while the force of gravity is the force acting to pull the nails to the
ground. If when Juanita sticks the seventh nail, it falls off the sixth nail,
it means that the force of gravity acting on the seventh nail is stronger than
the force of magnetism acting on it.
For the first 2 rows it’s going to be the dominant phenotype. So “purple flowers” for the 1st and 2nd row and white flowers for the last one. For the first row on #17 it’s going to be “FF “and “ff” for the 2nd. Tongue roller is “TT” and non tongue roller is “tt.”
The answer should be Atlantic Coastal Plain
