Answer:
450 Å
Explanation:
The amino acids in an α-helix are arranged in a right-handed helical structure where each amino acid residue corresponds to a 100° turn in the helix, and a translation of 1.5 Å (0.15 nm) along the helical axis
Mass of protein= 33.0 kDa
33.0 kDa ×(1000Da/kDa) × ( 1 residue/ 110 Da)
=33.0 ×1000 × 0.0091
= 300 residues
300 residues × (1.5Å /residue)
=450 Å
<span>The number of electrons in an atom's outermost valence shell governs its bonding behavior.
In N</span>₂, three electrons are being shared by each nitrogen atom, making a total of 6 shared electrons.
In CCl₄, 4 electrons are being shared by each carbon atom and 1 electron is being shared by each chlorine atom
In SiO₂, 4 electrons are being shared by each silicon atom and 2 electrons are being shared by each oxygen atom.
In AlCl₃, 3 electrons are being shared by each aluminum atom and 1 electron is being shared by each Cl atom
In CaCl₂, 2 electrons are lost by the calcium atom and 1 electron is gained by each chlorine atom
In LiBr, 1 electron is lost by the lithium atom and 1 electron is gained by the bromine atom
4. the nervous system uses electrical impulses to send messages through neurons while endocrine glands use hormones to send messages
5. Hormones are released from the endocrine glands
6. a. neck
b. Chest
7. help regulate important functions, such as growth, blood pressure and reproduction; it is small and small and bean shaped.
8. produces hormones that regulate the body's metabolic rate controlling heart, muscle and digestive function, brain development.
9. regulate your metabolism, immune system, blood pressure, respond to stress etc.
10. “enzymes” - break down sugars, fats, and starches
11. cells are unable to use glucose (can’t break down sugar to use as energy)
Answer:
Final concentration of NaOH = 0.75 M
Explanation:
For
:-
Given mass = 90.0 g
Molar mass of NaOH = 39.997 g/mol
The formula for the calculation of moles is shown below:
Thus,

Molarity is defined as the number of moles present in one liter of the solution. It is basically the ratio of the moles of the solute to the liters of the solution.
The expression for the molarity, according to its definition is shown below as:
Where, Volume must be in Liter.
It is denoted by M.
Given, Volume = 3.00 L
So,
<u>Final concentration of NaOH = 0.75 M</u>
