Answer:
Frog - The frog has three respiratory surfaces on its body that it uses to exchange gas with the surroundings: the skin, in the lungs and on the lining of the mouth. ... A frog may also breathe much like a human, by taking air in through their nostrils and down into their lungs.
Tadpole - Tadpoles open their mouths as they swim and take in water. As the mouth closes, muscles transfer the water to the gills. These consist of thin membranes called lamellae, which take oxygen from the water where it enters the blood stream through the process of diffusion.
Answer:all homozygous dominant
Explanation: traits are known to be controlled by genes in the chromosomes.from mendels work a test cross between a homozygous rr male and a female would produce r gametes each,which when crossed produces a rr ofspring,which is homozygous for the trait

Answer:
c. time to reach maximum tension
Explanation:
Muscle tension is defined as the contraction of muscles for an extended period of time. Physiological effects such as running and exercise of stress are the cause of muscle tension.
Skeletal muscle fibres into two types including slow-twitch (type I) and fast-twitch (type II).
- Muscle fibres of type I are more effective over long time periods. They are used mainly for postural maintenance (such as keeping the head upright), or mobility exercises (running).
- Type II muscle fibres use anaerobic breathing, and are stronger than Type I fibres for quick bursts of energy, even though they fatigue quicker.
So the muscle fibers divided on the basis of time to reach maximum tension while doing physiological activities.
Hence, the correct option is C.
