The force that gravity exerts on an object is called weight.

The shape of a planet’s orbit is elliptical.

The second law of planetary motion states that each planet revolves so that an imaginary line connecting it to the sun sweeps over equal areas in equal time intervals.

ans.

gregor john mendel is known for study of inheritance in pea plants. he used garden pea plant for his study, having alternative traits for various characters. he performed cross-breeding in pea plants to check how characters are transmitted between parents to offspring, such as cross between pure tall and pure dwarf plant. mendel studied the inheritance patterns in pea plants for various generations.

thus, the correct answer includes options and f).
