Answer:
D. magnitude
Explanation:
Scalars are quantities that are fully described by their magnitude (size) only. For example, a temperature is fully described by saying "80 degrees Celsius." We do not need to include a direction.
A vector contains both magnitude and direction. Acceleration is fully described by including both speed and direction: "45 m/s, North."
Both scalars and vectors have magnitude.
Ions that are made of more than one atom are called polyatomic ion
Answer: d. breakdown starch
Explanation:
The hydrochloric acid is produced by the parietal cells of the gastric glands present in the stomach. The primary function of the hydrochloric acid is to sterilize the food consumed by the human being. The acidic pH is unsuitable for the survival of the microbes present in the stomach. It triggers the activation of enzyme pepsin which is responsible for denaturation of proteins. The pepsin converts the protein into simple form of amino acids hence, facilitates the digestion of protein content in food.
The starch present in the food is digested by the enzyme called as salivary amylase present in the saliva present inside the mouth. The breakdown and digestion of starch is not the function of the hydrochloric acid.
