Answer:
D. Weight varies with location, but mass does not vary
Explanation:
Weight can be defined as the force acting on a body or an object as a result of gravity.
Mathematically, the weight of an object is given by the formula;
Where;
- m is the mass of the object.
- g is the acceleration due to gravity.
Mass can be defined as a measure of the amount of matter an object or a body comprises of. The standard unit of measurement of the mass of an object or a body is kilograms.
Irrespective of the location of an object or a body at a given moment in time, the mass (amount of matter that they're made up of) is constant. This ultimately implies that, whether you're in the moon, space, earth or any other place, your mass remains the same (constant).
<em>Hence, the statement that correctly compares mass and weight is that, weight varies with location, but mass does not vary. This is simply because acceleration due to gravity changes with location i.e its value varies with the planets.</em>
Answer:
Single celled organism that love moisture is yeast.
Explanation:
Yeast is a single cell organism that is grouped with kingdom fungi. The commonly known yeast is <em>Saccharomyces cerevisiae </em>that is used for baking and brewing industry. Yeast fermentation requires moisture and a warm environment. The moisture and carbohydrates are hydrolyzed during fermentation process to the simple sugars.

Answer:
sympathetic nervous system
Explanation:
The sympathetic nervous system functions like a gas pedal in a car. It triggers the fight-or-flight response, providing the body with a burst of energy so that it can respond to perceived dangers.
