Answer:

i know this is late but is 1

Explanation:

According to the law of conservation of matter, the number of atoms of each element involved in a chemical reaction stays the same no matter how they are arranged.

So, even though oxygen is combined with hydrogen on the reactant side, the total number of oxygen atoms remains the same after the reaction takes place. There are two atoms of oxygen on the reactant side, and two on the product side.

The animal cells produce the collagen but the plant cell does not produce collagen that responsible for producing the complex structure of protein and carbohydrates that is called extracellular matrix cell. Collagen is an important protein that provides strength to the structural integrity. On the other hand, the plant has not collagen so they have their extracellular supportive structure. The cell wall is so rigid and covered by the cell that protects it that provides shape and support to it. The plant cell also made up of molecules and these are called cellulose.

ELEN [110]

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.
