LuckyWell [14K]

Answer:

The correct answer is option C- "oxidize, reduce".

Explanation:

Fermentation is a process analogous to cellular respiration and, just like the latter, it involves oxidization and reduction of molecules with the final purpose of producing energy. During the process of fermentation nicotinamide adenine dinucleotide + hydrogen (NADH) is oxidized to its original form of NAD with a plus charge; while other organic molecules such as piruvate are reduced.

Alex_Xolod [135]

Answer:

<em>Food and shelter are the most likely limiting factors in this case.</em>

Explanation:

In a forest, the huge trees act as a source of shelter for the animals that live in that habitat. It protects the animals from the heat of the Sun and extreme cold conditions.

The tress in the forest are the primary source of food for almost all the organisms that live in the forest. Cutting down trees will lead to food scarcity for the animals which inhabit that forest. As a result, the animals will either have to migrate or they will become die due to lack of food.

Hence, food and shelter are the limiting factors in this case.

wind energy gaining support as a possible energy source for people. what is the source of the energy that generated wind?
Ivahew [28]

<u>Answer</u>: The energy source that generates wind is actually the sun.

<u>Explanation</u>: The uneven heating of the Earth's surface by the sun gives rise to differences in atmospheric pressure. Areas such as deserts will warm the air masses above much more. As air is heated, it has a lower density as it expands and thus will form a point of low atmospheric pressure. The opposite situation applies for high pressure areas.The air movement from areas of high pressure to areas of lower pressure is what we call wind.

Degger [83]

Adhesion depends on binding between specific molecules on both the host and pathogen so that the pathogen can gain a stable foothold on host tissues.

<h3>What is adhesion?</h3>

In epidemiology, adhesion makes reference to the process in which pathogen and host interact during an infection.

The adhesion process is fundamental to reach the survival of the pathogen during a particular infection.

These pathogens can be any type of microorganism able to cause harm to the host (e.g., bacteria and fungi).
