The law states that the total mass before a chemical reaction is the same as the total mass after a chemical reactionExothermic reactions do not require any activation energy.

Answer:

According to the law of conservation of mass, the masses of the products and reactants must be the same. Adding calcium to the product side is considered a mistake if it is not in the reactant side of a particular chemical equation because it is impossible to produce calcium from thin air (unless this is a nuclear reaction).

Anna [14]

Answer:

Option D (Aversion therapy) is the appropriate choice.

Explanation:

  • A type of behavioral treatment that involves aversive manipulation to mitigate or suppress the action of symptoms or conditions, combining harmful behavior or symptoms towards negative stimuli.
  • Closely connected with aversive conditioning, another terminology is more often used. See conduct counseling for behavior modification.

Some other alternatives are also not relevant to the current situation presented. So, the solution is indeed the correct version.

In the experiments conducted by Avery, McCarty, and MacLeod, which hypothetical result would indicate that protein, not nucleic
Jobisdone [24]

Answer:

Only the extracts from heat-killed cells treated with RNase are unable to transform nonvirulent bacteria into virulent bacteria.

Explanation:

The experiment by Avery, McCarty and MacLeod aimed to identify Griffith's "transforming principle," which is a principle that explains how transformation is a way of recombining, exchanging, or transferring genetic information between organisms or from one organism to another. For this, they used cell that were heat inactivated and purified the transforming principle of these cells.

The purified cells did not give positive results in the tests done by the scientists, but they presented transformants very similar to the DNA. However, Avery suspected that the result should be reinterpreted and that the molecule was not a DNA. This is because RNA degrading enzymes had no effect on the transforming principle and only RNase-treated heat-killed cell extracts are unable to transform non-virulent bacteria into virulent bacteria.

Which type of pulmonary disease affects the inspiratory volume of the lungs?
cluponka [151]

Answer:

Restrictive lung disease.

Explanation:

Restrictive lung disease may be defined as medical condition in which the lungs cannot be fully expanded. The lung capacity is decreased in this pulmonary disease.

Restrictive lung disease may decrease the inspiratory volume of the lungs whereas the expiratory volume is normal of an individual. This disease may get worse over time.

Thus, the correct answer is option (b).
