Answer:
Explanation:
Electromagnetic waves all travel at the speed of light when in vacuum, and essentially this same speed in normal air. Since wave speed is product of frequency and wavelength, c = f λ and λ = c/f = (3.00 x 108 m/s) / (7.5 x 1014 Hz) = 4.00 x 10-7 m = 400 x 10-9 m = 400 nm.
Answer:
The correct answer is A The student is investigating the passive transport of diffusion.
Explanation:
Diffusion is a type of transport process which helps in the transport of small molecules and gases towards their concentration gradient that"s means from region of high concentration to the low concentration region untill equilibrium is reached.
In this question the 10 drops are red coloured food particles that are placed into the beaker, diffuses to all the regions of the beaker untill the concentration of that red colored food particle become same in all the regions to which red colored food particle diffuse.
Bacteria can convert nitrogen in the air into a form plants can use
Answer:
The carbon atom has unique properties that allow it to form covalent bonds to as many as four different atoms, making this versatile element ideal to serve as the basic structural component, or “backbone,” of the macromolecules.
All living things contain carbon in some form. Carbon is the primary component of macromolecules, including proteins, lipids, nucleic acids, and carbohydrates. Carbon's molecular structure allows it to bond in many different ways and with many different elements.
