Instant reaction time is a stimulus response. The quickness with which the reaction is given back to a particular type of situation is called as the instant reaction.
The types of stimulus are external and internal.
External stimulus is the quick response of the body to the quick incident that is happening outside. For example when we touch a hot body the hand goes back quickly and this is the external stimulus up in the body happening.
Internal stimulus is the stimulus in which a body reaction to any type of drug or medicine is taken not only drug or medicine but a certain substance is eaten too.

Answer: first statement that Keratin is a protein in the cells of the epidermis that provides strength and waterproofing is correct
Explanation:
The outer layer of skin, the epidermis, provides waterproofing and serves as a barrier to infection.
The middle layer of skin, the dermis, contains blood vessels, nerves, and glands that are important for our skin’s function. The inner layer of the skin, the subcutis, contains fat that protects us from trauma. The cells in all of the layers except the stratum basale are called keratinocytes. A keratinocyte is a cell that manufactures and stores the protein keratin. Keratin is an intracellular fibrous protein that gives hair, nails, and skin their hardness and water-resistant properties.
Keratin is an important protein in the epidermis. Keratin has two main functions: to adhere cells to each other and to form a protective layer on the outside of the skin. In epithelial cells, keratin proteins inside the cell attach to proteins called desmosomes on the surface.
The true statement about the skin is that keratin, produced by Keratinocytes in the epidermis, provides skin its strength and waterproofing. Melanocytes in the epidermis produce Melanin, not Calcium. Sebacious and sweat glands are exocrine, not endocrine, and are located in the dermis. The hypodermis, not the basement membrane, is found below the dermis.
The correct statement about the skin is that 'Keratin is a protein in the cells of the epidermis that provides strength and waterproofing'. Keratin is an intracellular fibrous protein that gives hair, nails, and skin their hardness and water-resistant properties. These Keratinocytes are found in the epidermis, the outermost layer of the skin, where they produce Keratin. Melanocytes, another type of skin cells, also reside in the epidermis. They produce Melanin, the pigment responsible for skin color, rather than Calcium.
Regarding the other statements, Sebacious and sweat glands are not endocrine but are exocrine glands, as they release their secretions directly to the skin's surface, not in the bloodstream. These glands are located in the dermis, the layer beneath the epidermis. Beneath the dermis lies not the basement membrane, but the hypodermis.

c. amount of carbohydrates
d. total servings of vegetables

Answer: If someone is exercising 3 times a week, chances are they are also taking part in other healthy activities.
Explanation: This can include diet, and sufficient amount of sleep. Also, if someone has time to work out many times a week, they probably have a lot of free time, and therefore, less stress from work or school. All of these things affect your lifespan; it isn't a direct cause of the exercising.
