Failure to bend the knees and lower the body until the surface of the legs at the hip joint is lower than the top of the knees describes squat past parallel. Thus, the correct option is A.
<h3>
What is parallel for a squat?</h3>
The exerciser lowers their hips till the tops of their thighs are parallel to the floor while keeping their lower back flat and their chest up in a proper parallel squat.
In fact, if your weight is distributed correctly and you maintain good posture during the movement, a full squat (below parallel) may actually produce more knee stability.

Hello there.
<span>Protein transporters that move materials against a concentration gradient are active transport proteins.
True</span>
Answer:
The correct option is B
Explanation:
Isotopes of the same element have the same atomic number (number of protons) but different mass number. Hence, <u>all the three naturally occurring carbon isotopes mentioned in the question have 6 protons each. Since the number of protons in a neutral atom is equal to the number of electrons in the same atom, each of these isotopes also have 6 electrons</u>.
However, to determine the number of neutrons in each atom, the number of protons (atomic number) is subtracted from the mass number.
Hence, the number of neutrons in carbon-12 is 12 - 6 = 6
the number of neutrons in carbon-13 is 13 - 6 = 7
the number of neutrons in carbon-14 is 14 - 6 = 8
From the explanation above, <u>it can be noted that the number of protons and electrons in isotopes of the same element are the same while the number of neutrons in these isotopes are different</u>. Hence, the correct option is B
