Answer:
water is a covalent compound consisting of hydrogen and oxygen . it contains Single covalent bond
1. An infinitely dense atom of matter explodes, releasing all matter in the known universe.
2. This matter clumps together forming rocks and dust; that which doesnt compact remains as gas.
3. The rocks and dust are pulled in to each other by their own gravity. These clumps get bigger and bigger, and form planets.
4. Gas and dust clouds, better known as nebulae, (sing. nebula) begin to react, clump together and generate heat. Stars are formed out of these nebulae (unsure of the process).
5. The stars, with their powerful gravitational pulls, drag in planets to form solar systems. This happens on a larger scale as well, as groups of millions of stars are formed into galaxies, huge swirling discs containing millions of stars each.
That's where we are today.
A product of the oxidation of odd-chain fatty acids, Propionyl-CoA, is converted to succinyl-CoA and enters the citric acid cycle.
<h3>What is oxidation ?</h3>
Redox reactions involve a change in the oxidation state of the substrate. Oxidation is the process of losing electrons or increasing an element's oxidation state. Reduction can occur when an element or one of its constituent atoms gains electrons or has their oxidation status decreased.
When an object comes into touch with oxygen or another oxidizer, a chemical reaction occurs. Rust and the brown color of a sliced apple are both examples of oxidation.
<h3>How is oxidation occur ?</h3>
When an atom, molecule, or ion loses one or more electrons during a chemical reaction, oxidation takes place. The chemical species' oxidation state increases while oxidation takes place. Oxygen is not always necessary for oxidation to occur. The phrase was initially used when oxygen produced an electron loss during a process.

With fossils, scientists can use carbon dating to determine the approximate age of whatever fossil they have.
Answer:
Explanation:
Gram-negative bacteria are more resistant to lysozyme and antibiotics than Gram-positive bacteria, because they have a largely thick impermeable cell wall (peptidoglycan), an outer lipid membrane that causes reaching of antibiotics to bacteria harder.
Gram positive bacteria have thin lipid peptidoglycan cell walls.
