By the passage of time, from fin on lobe-finned fish changed to legs and feet on the early amphibians due to variations among offspring, followed by natural selection. These legs and feet containing amphibians lives both in water and land.
Answer:
Trunk flexor endurance test.
Explanation:
McGill’s torso muscular test is generally used to assess the muscle endurance of the torso muscles that works as a stabilizer. This test generally includes the four major test.
The test that includes the trunk flexor of the endurance test is a timed test that involves the static isometric contraction of the muscles. This test stabilizes the spine til the individual cannot hold the assumed position and the individual exhibits the fatigue.
Thus, the correct answer is option (A).
The correct answer is 'If molecules are small enough, then they can pass through the semipermeable membrane because they can cross the semipermeable membrane from their small pores or openings'.
The semipermeable membrane is permeable to few molecules, and the smaller molecules pass through the molecules from small pores present in the semipermeable membrane. The size of the big molecules are large, so, they cannot cross through semipermeable membrane.
Light receptors within the eye transmit messages to the brain, which produces the familiar sensations of color. Newton observed that color is not inherent in objects. Rather, the surface of an object reflects some colors and absorbs all the others. We perceiveonly the reflected colors.
