An alpha helix which is 18 amino acids long will have 12 hydrogen bonds.

<h3>What is alpha helix (α-helix) ?</h3>

The alpha helix (α-helix) is a common in the secondary structure of proteins and is a right hand-helix conformation in which every backbone N−H group hydrogen bonds to the backbone C=O. group of the amino acid located four residues earlier along the protein sequence.

The alpha helix is stabilized by hydrogen bonds (shown as dashed lines) from the carbonyl oxygen of one amino acid to the amino group of a second amino acid.

Because the amino acids connected by each hydrogen bond are four apart in the primary sequence, these main chain hydrogen bonds are called "n to n+4.

Answer:

Alloys and Composites

Explanation:

<u>Drill bits are made of alloys</u> because alloys are very much resistant to corrosion and are created when one or multiple metals are mixed with other elements that are non-metallic in nature. Due to their greater strength, they are used in the power drills in order to create borehole drills at the mining site. Borehole drilling is commonly done in order to understand the sub-surface strata before mining.

<u>The bodies along with the handles of power drills are constructed of composite insulators</u> because within the composites there is the absence of free electrons that has the ability to flow and produce electricity. So they are considered to be used as a good insulator.

A word which describes a solution which is more dilute than cytoplasm and would cause a cell to swell with water
Snowcat [4.5K]

Answer:

A hypertonic solution has increased solute, and a net movement of water outside causing the cell to shrink. A hypotonic solution has decreased solute concentration, and a net movement of water inside the cell, causing swelling or breakage.

Explanation: hope this helps :) sorry if it's wrong :(

which number should be placed before F2 on the reactants side equation to make equation balanced? Xe + ___F2 &gt; XeF4
Ivahew [28]

There are four F atoms on the products side.

Since two more F atoms are required on the reactant side, you multiply the number of F2 molecules by two.

So 2 should be placed in front of F2
