Answer:
A)
Explanation:
Heredity is a process in which organisms acquire characteristics from their parents. These characteristics are called traits. Every individual is unique because they have a unique set of traits. The traits which are transmitted by the parent to its offspring during the process of fertilization are inherited traits. This inheritance is determined by certain rules of heredity. Inherited traits are coded in our DNA and hence can be passed on to the next generation.
Answer:
Responding to the environment
Explanation:
Sweating and panting are mechanisms of homeostasis i.e the regulation of the body's internal environment in response to changes or fluctuations in the external environment.
Sweating is a physiological response to the body's core temperature rising above the limit of 36.5-37.5°C. Once the hypothalamus in the brain detects this rise in temperature, cooling mechanisms are initiated. One of these is sweating. Release and subsequent evaporation of sweat through the sweat glands produces a cooling effect.
Panting is a physiological response more observed in dogs. Dogs lack sweat glands and therefore cannot lower their core temperature through sweating. Panting utilizes saliva instead of sweat to lower body's temperature to the set limit.
