Answer:
B
Explanation:
The dermis is the layer of skin below the epidermis. Below the dermis is the subcutaneous layer. It contains connective tissue from collagen and elastic fibers giving skin its elasticity. It contains nerve fibers sensitive to heat and touch. Glands - like sebaceous & sweat glands, hair follicles, and blood capillaries that supply the skin, are found in this layer.
Answer:
D: 4.6 x 
Explanation:
4.6 x 10^{9} = 4,600,000,000
Earth is approximately, 4.6 billion = 4,600,000,000 = 4.6 x 10^{9}
Respiration is how animal cells get their energy to preform their necessary functions. Plant cells don't use respiration, because they use photosynthesis. Photosynthesis turns light into energy.
Tid-bit of info:
Cellular Respiration Formula:
Sugar + Oxygen = Carbon Dioxide + Water <span>+ ATP </span>
C₆H₁₂O₆ + O₂ = CO₂ + H₂O <span>+ ATP </span>
Photosynthesis Formula:
Sunlight + Water + Carbon Dioxide = Oxygen + Sugar
Sunlight + H₂O + CO₂ = O₂ + C₆H₁₂O₆

Answer:
option B) is correct
Explanation:
The all or none response means that if a muscle contracts, it will contract completely. Thus implying the all or none law which states:
The potential of a response of a muscle fiber or nerve cell is independent of the potential of the stimulus. If a stimulus is more than a certain critical value it will trigger muscle fiber or a nerve. Most importantly resulting in either an all-or-none response thus reducing possibility of any information loss.
