<u>do mark me as brainlist</u>

Biomolecules are made by living organisms and they are made because they are functional. Biomolecules, or at least most of them, do not exist outside of living organisms because they are too complex to be created by chance chemical collisions. The odds of a single average sized protein to form by chance has been calculated at 1 out 10 to the 77th power. Biomolecules REQUIRE intelligent agency to form them.

The four main purposes of biomolecules are:

1. Structure (some proteins)

2. Energy storage and release (carbohydrates)  

3. Protective layers (lipids)

4. Information storage and communication (DNA, RNA, endocrines of numerous various types and manipulated molecules, such as fatty acids)

Answer:

Robert Hooke used an early microscope to observe a cork sample. How did this help contribute to cell theory? It helped to show that cells contain water. ... It helped to show that some cells are visible to the naked eye.

What is Newton's Second Law of Motion? (2 points) Every reaction is equal to the force applied. Forces are balanced when they ar
raketka [301]

Well, they're not quite the way Newton expressed it, but out of all this mess of statements, there are two that are correct AND come from Newton's 2nd Law of Motion:

<em>-- The smaller the mass of an object, the greater the acceleration of that object when a force is applied. </em>

<em>-- The greater the force applied, the greater the acceleration.</em>

For the <u><em>other </em></u>statements in the question:

-- <em>Every reaction is equal to the force applied.</em>  True; comes from Newton's <u><em>3rd</em></u> law of motion.

-- <em>Forces are balanced when they are equal and opposite.</em>  True; kind of a definition, not from Newton's laws of motion.

-- <em>An object at rest or in motion will remain at rest or in motion unless acted upon by an unbalanced force. </em>  True; comes from Newton's <em><u>1st </u></em>law of motion.

A grating that has 3900 slits per cm produces a third- order fringe at a 28.0° angle. What wavelength of light is being used? Ex
Zolol [24]

Explanation:

Given that,

Number of slits per cm, N=3900\ lines/cm=390000\lines/m

The third fringe is obtained at an angle of, \theta=28

We need to find the wavelength of light used. The grating equation is given by :

d\ sin\theta=n\lambda

d=\dfrac{1}{N}=\dfrac{1}{390000}

d=2.56\times 10^{-6}\ m

\lambda=\dfrac{d\ sin\theta}{n}, n = 3

\lambda=\dfrac{2.56\times 10^{-6}\times \ sin(28)}{3}

\lambda=4.006\times 10^{-7}\ m

\lambda=400\ nm

So, the wavelength of the light is 400 nm. Hence, this is the required solution.
