Answer:
ventricles (VEN-trih-kuhls): The two chambers at the bottom of the heart are called the ventricles. The heart has a left ventricle and a right ventricle. Their job is to pump the blood to the body and lungs.

Light-year or lightyear (symbol: ly) is a unit of measurement of length, specifically the distance light travels in a vacuum in one year.
While there is no authoritative decision on which year is used, the International Astronomical Union (IAU) recommends the Julian year.
A light-year is equal to 9,460,730,472,580.8 km (about 9.461 Pm; 5,878,625,373,183.61 statute miles; about 63,240 astronomical units or about 0.3066 parsecs.
The exact length of the light-year depends on the length of the reference year used in the calculation, and there is no wide consensus on the reference to be used.
The figures above are based on a reference year of exactly 365.25 days (each of exactly 86,400 SI seconds).
A few examples of distances for light to travel are: Reflected sunlight from the Moon's surface takes 1.3 seconds to travel the 4.04 × 10-8 light years to Earth.
It takes 8.3 minutes for light to travel from the Sun to the Earth (a distance of 1.58 × 10-5 light-years).
The most distant space probe, Voyager 1, was 13 light hours (only 1.5 × 10-3 light years) away from Earth in September 2004.
It took Voyager 27 years to cover that distance.
The nearest known star (other than the Sun), Proxima Centauri is 4.22 light years away.
The center of our galaxy, the Milky Way, is about 26,000 light years away.
The correct answer is A. A law
Explanation:
In science, a law describes a phenomenon or event that always occurs under specific circumstances, and therefore it is constant. Due to this, laws are created based on multiple experiments or observations that lead to the same result. Also, a law only describes a phenomenon but does not explain why this occurs, which belongs to scientific theories.
The statement "traits are passed from parents to offspring independently of one another" by Mendel is a law because it describes a proven and constant phenomenon in genetics. Also, this is the result of the multiple experiments made by Mendel that showed the same result in terms of genetics.
