It is a winter day in florida, and the temperature is 40°f in the morning. while you are walking to class, your body uses a negative feedback loop in order to shiver and maintain your internal body temperature at 98.6°f. after class, the temperature outside has increased to 80°f and you begin to sweat since you are still wearing your winter clothes. is the process of sweating in order to cool down and maintain an internal body temperature of 98.6°f an example of a positive or negative feedback loop?

negative feedback

Explanation:

The negative feedback system is the most common in the body, being considered by many authors the primary mechanism for the maintenance of homeostasis. It causes a negative change from the initial change, that is, a stimulus contrary to the one that led to the imbalance. In the case of the above question, when the ambient temperature increased, your body began to sweat to lower the temperature, that is, your body is trying to make a stimulus contrary to what is happening in the environment, so we can state that your body is going through a negative feedback system.

the answer to this question is a

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
