Answer:

A. Endergonic

Explanation:

Free energy refers to the component of the total energy of a system that is available to perform work at constant temperature and pressure. It depends on entropy, enthalpy and temperature. Free energy of a reaction is denoted by letter "G". Free-energy change (delta G) is the amount of free energy released or absorbed during a reaction at constant temperature and pressure.

When substrates absorb energy during the reaction, the delta G becomes positive. On the other hand, when the substrates release energy during reactions, the free energy change for the reaction is said to be negative. A reaction with positive free energy change is endergonic and non-spontaneous while the ones with negative free energy change are exergonic and spontaneous.

If Avery had observed transformation using only the extracts containing degraded DNA, degraded RNA, and degraded protein, but NO

Leokris [45]

Answer:

Polysaccharides are the genetic material.

Explanation:

Avery did not observe transformation using the extracts containing degraded DNA. On the other hand, extracts with degraded RNA, proteins, and polysaccharides exhibited transformation. Therefore, he concluded that DNA is the genetic material responsible for transformation. If he would have observed the process of transformation using extracts containing degraded DNA but not with degraded polysaccharides, he might have concluded that "polysaccharides were the genetic material responsible for the process of transformation."
