Passice immunity
Explanation:
Breast milk, produced by female mammals (including humans), besides being rich in fat and protein is full of IgA. IgA is the immunoglobulin (immune system signal proteins) that is present in body secretions, such as milk.
The baby that is fed from the mother's breast ingests these defense proteins that allow it to tolerate different pathogens and toxins.
It is considered passive immunity, as it does not generate memory and depends on a continuous dose to maintain defense levels.
The statement that "birds build nests to keep the egg warms" describes a result.
The scientific method refers to an arrangement of steps succeeded by scientific investigators to answer particular questions regarding the natural world. It includes making observations, creating a hypothesis, and conducting scientific experiments.
The steps of the scientific method are observation, question, hypothesis, experiment, results, and conclusion. The result illustrates when one report what took place in the experiment. This comprises detailing of all the data and observations made at the time of the experiment.
The temperature at which the amylase catalyzed reaction is fastest is significant because that is the optimum temperature for the enzyme.
Amylase is an enzyme that catalyzes the digestion of enzyme. The optimum temperature of an enzyme is the temperature at which it works best. The optimum temperature of amylase is approximately 37 degree Celsius; this temperature also happen to be the normal body temperature.<span />
