Answer:
The conversion is needed to regenerate the molecules needed for glycolysis
Explanation:
Fermentation is a metabolic process by which microorganisms generate ATP by the anaerobic (without oxygen) degradation of organic nutrients. Fermentation allows to microorganisms convert carbohydrates into alcohol or acid. During glycolysis, two NAD+ molecules are reduced and glucose molecules are split into two pyruvate molecules, thereby producing two NADH molecules and two ATP molecules. During fermentation, pyruvate molecules are metabolized to different compounds because the energy stored in the pyruvate molecules is unavailable to the cell. In fermentation, NADH from glycolysis is oxidized back to NAD+ by being used to reduce pyruvate or a pyruvate derivative.
If a plant has no Casparian strips, it will not be able to
control the amount of water it absorbs and solutes. Casparian strips regulate
the amount of water that gets to the xylem. Without it, a plant won’t be able
to control the amount of water going to the xylem.

Chromatin is a part of the spindle apparatus
Explanation:
Chromosome is not only responsible for genetic material. Chromatin is that substance which consists of protein and DNA. Here DNA carries genetic instruction. Histones are main proteins of chromatin. It is also called the packaging of element for the DNA.
In two forms chromatin exist. One is euchromatin and another is heterochromatin. Euchromatin is less condensed and it can be transcribed. Heterochromatin is highly condensed and typically not transcribed. Chromosomal pathway regulates spindle assembly.
DNA is made out of Deoxyribose sugar, phosphate, and nucleotides
The only competitors that humans have for food are other humans and insects: Agree; we do compete with other animals for food
<u>Explanation:</u>
The term competitor is used to describe interaction that takes place within any two organisms as a result of which both the organisms are affected. The functional role that an organism have within the environment is known as Niche.
Parasitism refers to the interaction that takes place between any two organisms or species as a result of which only one will get benefits and the other one will be getting affected.In an ecosystem, every organism strives hard for living and need food for its survival. Hence, the competitors for food in an ecosystem will be other human, insects, animals, etc.
