Answer:
A) Light is made up of waves.
Explanation:
Light is a form of electromagnetic waves.
Electromagnetic waves consist of electric and magnetic fields that oscillate periodically in a plane perpendicular to the direction of motion of the wave, therefore they are transverse in nature.
All electromagnetic waves travel in a vacuum at the speed of light:

Moreover, electromagnetic waves are classified into 7 different types depending on their frequency and wavelength. From lowest to highest frequency (and so, from longest to shortest wavelength), we have:
Radio waves
Microwaves
Ultraviolet
Visible light
Infrared
X-rays
Gamma rays
Visible light is part of this electromagnetic spectrum, and corresponds to the part of the electromagnetic waves that our eye is able to see. In particular, we perceive waves of different wavelength and frequency as different colors: for instance, violet/blue light corresponds to the shortest wavelength that we can see, while red light corresponds to the longest wavelength that we are able to see.
Also, for visible light wave we can describe their brightness, which corresponds to the intensity of the wave, which is a property of all waves.
So the correct answer is
A) Light is made up of waves
A gene that has been associated with a language disorder in humans and is quite different in apes is the FOXP2 gene.
Self intrest and exchanging things for mutual benefit
With the ocean providing over half the oxygen we breathe and being a major source of food for the world’s population, there is a critical need for action and we all have the ability to make change.
Each year, at least eight million tonnes of plastics flow into the ocean — which is equivalent to dumping the contents of one garbage truck into the ocean every minute. If no action is taken, this is expected to increase to two per minute by 2030 and four per minute by 2050.
It’s sad to look at this picture and NOT look at how hurt sea animals are being hurt, how this WILL affect us in the near future, maybe even affecting us right now and we are too blind to notice. It’s painful to think of these things because sooo much is being lost. I hope people can open there eyes and realize the damage they are causing.
