Answer:
Serine will be on the exterior of the globular protein while leucine on the interior of the globular proteins
Explanation:
The nature or solubility of the side cham determines the poition of amino acid on the globular protein and it is either hydrophilic or hydrophobic.
Serine is an hydrophilic amino acid and so it is position on the surface of the globular protein (Exterior)
While Leucine side chain is hydrophobic in nature is positioned on the interior of the globular protein.
Answer:
A system is a collection of elements or components that are organized for a common purpose. ... All of nature and the universe can be said to be a system. We've coined a word, ecosystem, for the systems on Earth that affect life systems. The term can be very useful because so many things can be described as systems.
In order to measure 0.733 moles of KBr from a 3.00 M solution, the chemist needs 244 mL of solution.
<h3>What is molarity?</h3>
Molarity (M) is a unit of concentration of solutions, and it is defined as the moles of a solute per liters of a solution.
- Step 1: Calculate the liters of solution required.
A chemist has a 3.00 M KBr solution and wants to measure 0.733 moles of KBr. The required volume is:
0.733 mol × (1 L/3.00 mol) = 0.244 L
- Step 2: Convert 0.244 L to mL.
We will use the conversion factor 1 L = 1000 mL.
0.244 L × (1000 mL/1 L) = 244 mL
In order to measure 0.733 moles of KBr from a 3.00 M solution, the chemist needs 244 mL of solution.

Answer:
Frequency = 6.67x10¹⁹ s⁻¹
Wavelength = 4.46x10⁻⁷m
e = 2.27x10⁻¹⁹J
Explanation:
To convert frequency to wavelength and vice versa we use the equation:
Wavelength = Speed of light / Frequency
<em>Speed ligth is 3x10⁸m/s</em>
<em />
For a wavelength of 4.50x10⁻¹²m:
4.50x10⁻¹²m = 3x10⁸m/s / Frequency
Frequency = 3x10⁸m/s / 4.5x10⁻¹²m
<h3>Frequency = 6.67x10¹⁹ s⁻¹</h3><h3 />
For a frequency of 6.73x10¹⁴s⁻¹:
Wavelength = 3x10⁸m/s / 6.73x10¹⁴s⁻¹
<h3>Wavelength = 4.46x10⁻⁷m</h3>
<em />
And energy, e, from frequency, is obtained as follows:
e = h ₓ frequency
<em>Where h is Planck's constant, </em>6.626x10⁻³⁴J*s
e = 6.626x10⁻³⁴J*s*3.43x10¹⁴s⁻¹
<h3>e = 2.27x10⁻¹⁹J</h3>
