Answer:
The correct answer is - passive immunity - artificially acquired.
Explanation:
Passive immunity is the immunity that involves giving or acquiring antibodies from other sources instead of developing them on one's own. This type of immunity can be natural and artificial. Mother breastfeed the babies, is the natural passive immunity example as milk also contain antibodies required for immunity of babies.
Artificial passive immunity is the immunity that comes from injecting the antibodies created in different animals or persons which called antiserum or vaccines such as snake antivenom.
 
        
             
        
        
        
Answer:
Observing & Hypothesizing
Explanation:
The knowledge obtained when scientists answer one question often generates other questions or proves useful in solving other questions. Scientists gather information and answer questions collectively known as the scientific method.

<u>Answer</u>:
The food containing 200 calorie have less potential energy than the food containing 300 calorie
<u>Explanation</u>:
The potential energy content of a food material is its stored energy content which is in the form of chemical bonds. This energy can be measured through the combustion of food material inside a calorimeter. A calorimeter is an instrument which is used to measure the total calorie content of the food or other biological samples by measuring its heat content. A Calorie is unit of energy which is in form of heat. 
The food material containing carbohydrates proteins and fats have energy in form of chemical bonds.  On the breaking of bond inside the body, energy is released as in the case of glucose breakdown also known as glycolysis.  
The energy released from glycolysis is used to synthesize high energy containing phosphoanhydride bonds. These ATP molecules are a further breakdown in the system to provide energy to the cell to perform various activities.
