This doesn't seem like much of a biology question but more of a chemistry one :P

But to answer your question, as the temperature of the water molecules rises, the chemical bonds holding them together begin to fall apart, causing the structure of the ice to fall apart.

When water is evaporated, the chemical bonds holding the water molecules together becomes non-existent, and the water becomes a vapour in which molecules float independent of each other <span />

"One of the two major systems that are affected by the stress response is the ____________, which results in increased productio
MAXImum [283]

Answer:

The correct answer is the endocrine system.

Explanation:

The sympathetic division of the autonomic nervous system and the endocrine system are the two prime systems that take part in the stress response.  

At the time of acute or chronic stress, the endocrine system first makes the hypothalamus to discharge CRH or corticotropin-releasing hormone into the bloodstream. The release of CRH further makes the anterior pituitary to discharge ACTH or adrenocorticotropic hormone into the blood. This further stimulates the adrenal cortex to discharge cortisol, that is, one of the glucocorticoid hormone into the bloodstream.  

The cortisol finally makes the organs and tissues present within the body to effectively cope up with the initial stress stimulus.

Although the direct reduction of CoQ to CoQH2 is thermodynamically possible, this reaction is not a direct part of the electron
Nady [450]

Answer:

This electron handoff from NADH to FMN, as opposed to direct reduction of CoQ by NADH, a critical component of the electron transport chain is important for Signaling Transduction and Metabolomics

Explanation:

The NADH-CoQ reductase reaction is catalyzed by Complex I. In this course of activity, following events takes place-  

a) FNM (NADH dehydrogenase flavoprotein) is reduced by the NADH  to FMNH2 through following reactions –  

NADH+H++E-FMN↔NAD++E-FMNH2

b) In the next phase coenzyme Q  receives electron from FMNH2  through the the iron–sulfur centers of the NADH-CoQ reductase

c) The iron atom undergoes oxidation–reduction cycles to conserve  mitochondrial protein  as lataxin and hence transport protons from the matrix to the intermembranal space thereby Signaling Transduction and Metabolomics

Carbon and Hydrogen atoms share an electron pair, forming covalent bonds special properties of carbon is ability to form double and triple bonds.

<h3>What is molecule example?</h3>

A molecule is the smallest unit of any material that is composed of one or more elements and is capable of existing independently while maintaining all of the substance's physical and chemical properties. Further atom division occurs within molecules.For instance, each atoms the particle of oxygen are represented by the letters Oh and Water vapour, together.

<h3>How a molecule is formed?</h3>

When ionic compounds come together and form bonds with one another, a molecule is created. Each atom shares an electron when a bond is formed between them. A molecule is created as a result of a covalent bond.

What's the role of oxygen in cellular respiration?
Anuta_ua [19.1K]

Answer: D

Explanation: Oxygen plays a vital role in energy production via a system called electron transport chain , which is an important component of cellular respiration. ... Oxygen acts as a final electron acceptor that helps move electrons down a chain that results in adenosine triphosphate production
