Light is exactly similar to water and sound.

Light is a converse wave.

Answers

Light is a transverse wave and this is what describes light as a wave. The correct option among all the options that are given in the question is the first option. Light is not at all similar to water and sound. It would be a big mistake to consider light as similar to the mediums water and sound. I hope the answer helps.

Answer:

Light is a transverse wave.

Explanation:

Light is a transverse wave. Its particles vibrates or oscillates in the direction perpendicular to the direction of propagation of wave.

Light wave also have both electric and magnetic field component. So, light waves are also called as electromagnetic wave. Another type of wave is longitudinal wave. In this type, the particles of wave are in the direction of propagation of wave.

Hence, the correct option is " light is a transverse wave ".

Which of these is an abiotic factor of an aquarium ecosystem? a. algae growing on the glass
b. gravel on the bottom of the aquarium
c. plants growing from the gravel
d. fish swimming in the water

Answers

b. gravel on the bottom of the aquarium

An ecosystem involves both the biological (plants, animals, human beings) and non-biological (land, water, soil, and atmosphere) community which interacts as a system. More importantly, the living things are very dependent on the abiotic community since it cannot survive by itself. Every animal, plant and human needs the primary physiological needs of water, food and shelter provided by the abiotic system.   

Biotic factors:
Plants
Microorganisms
Macroorganisms

I am pretty sure that the answer is B! I just took the Test and it makes sense because abiotic means not living feature and gravel isn't a living feature! Hope this helps!

Organisms use different types of adaptations to aid in their survival. One type of butterfly mimics a dead leaf to evade predators. What type of adaptation is this?a. Biochemical
b. Ecological
c. Structural
d. Physiological

Answers

The correct answer is option C, that is, structural adaptation.  

All the species exhibit adaptations, which assist them to thrive and survive. Structural is one of the kinds of adaptations, these refer to the physical characteristics of an organism.  

Structural adaptation refers to the feature in an animal or plant's body, which assists it to thrive in its surroundings. The examples are possessing the tendency to retain water, and camouflage that is protective coloration.  
When one type of butterfly mimics a dead leaf to evade predators this would be referring to a "ecological adaptation" since it has to do mostly with the environment.
