If it takes 98.8 kcals to break one C--H found in an organic molecule, how many kcals does it take
steposvetlana [31]

395.2kcal

Explanation:

Given parameters:

Energy required to break one C-H bond = 98.8kcals

Unknown:

Energy required to break methane = ?

Solution:

The bond dissociation energy is the heat energy absorbed in breaking a covalent bond in the gas phase to its constituents elements.

  Solving

    CH₄ has 4 C-H bonds

To break 1 C-H bond, 98.8kcals of energy was used,

To break 4 of the bonds; 4 x 98.8kcals will be used = 395.2kcal

True or false conductive hearing loss results from damage to the inner ear or the vestibularcochlear nerve
pickupchik [31]
Conductive hearing loss occurs from either (1) blockage from the external ear or (2) damage to any components of the middle ear; hence the answer here is false. Hearing loss that results from damage to the inner ear or the vestibulocochlear nerve is called <em>sensorineural hearing loss</em>. 

<em>The most common cause of sensorineural hearing loss is noise-induced hearing loss due to prolonged exposure to high decibel environments (i.e. machine workers). </em>

What does reverse transcriptase use to form dna apex?
Marianna [84]

Reverse transcriptase use mRNA to form DNA apex

Reverse transcriptase is a broad family of enzymes that play a unique role in the flow of genetic information. The synthesis of DNA from an RNA template through reverse transcription produces complementary DNA. Reverse transcriptase use an RNA template and a short primer complementary to the 3' end of the RNA to direct the synthesis of the first strand complementary DNA, which can be used directly as a template for the Polymerase Chain Reaction.
