The correct answer is option C, that is, viruses.
An infection occurs when a foreign species moves inside the body of an individual and causes harm. The species utilizes the body of that person to reproduce, sustain itself, and colonize. These infectious species are called pathogens. The examples of pathogens are viruses, bacteria, prions, and fungi.
Of the given options, viruses are the smallest infectious agent. The viruses are basic particles, which must infect a host cell to reproduce and develop. Viruses utilize the host cells metabolic machinery to double themselves.
Answer:
A .a net force greater than zero
B. Unbalanced Force
Explanation:
A .When the resultant force on an object is zero, it will remain at rest if it is at rest, or continue to move in a straight line at a constant velocity if it is in motion. So , the answer will be a net force greater than zero .
B . An unbalanced force (net force) acting on an object changes its speed and/or direction of motion. An unbalanced force is an unopposed force that causes a change in motion. A net force = unbalanced force. So , the answer will be unbalanced forces .
As ice melts into water, kinetic energy is being added to the particles. This causes them to be 'excited' and they break the bonds that hold them together as a solid, resulting in a change of state: solid -liquid.
