Q:

A standing wave occurs when

A) a wave reflects upon itself B) the amplitude of a wave exceeds its wavelength
C) two waves overlap D) the speed of the wave is zero or near zero
 
Answer & Explanation Answer: A) a wave reflects upon itself

Explanation:

A standing wave also known as a stationary wave, is a wave in which its peaks or any other point on the wave do not move spatially.

This phenomenon can occur because the medium is moving in the opposite direction to the wave, or it can arise in a stationary medium as a result of interference between two waves traveling in opposite directions. The most common cause of standing waves is the phenomenon of resonance, in which standing waves occur inside a resonator due to interference between waves reflected back and forth at the resonator's resonant frequency.

 

Hence, standing wave occurs when a wave reflects upon itself.

Q:

Which of the following is an Abiotic factor?

A) Plants B) Water
C) Consumers D) Animals
 
Answer & Explanation Answer: B) Water

Explanation:

Abiotic and biotic factors are what make up an ecosystem.

 

Abiotic factors are all nonliving components of an ecosystem. These factors include chemical and geological features such as water or lack of water, soil, rocks, and minerals. Other abiotic factors include physical components such as the temperature and weather affecting the ecosystem.


The biotic factors in an ecosystem include all living things. All plants, animals, fungi, protists, and bacteria within an ecosystem make up that system's biotic factors. The biotic factors can be broken down further into producers, consumers, and decomposers.

The biotic factors present in an ecosystem are highly dependent on the abiotic factors that are present. Even slight changes to either factor can have a major consequence upon the system as a whole.
