Which role of water is significant for most living things in a biological system?a. It prevents many life processes from occurring.b. It slows down the transportation of nutrients.c. It provides temperature regulation.d. It does not freeze in cells at very cold temperatures.

Answers

Answer 1
Answer: I am pretty sure the correct answer is C.  Water has large heat capacity meaning it can absorb a lot of energy before changing temperature.  That helps the body regulate heat since it can be exposed to different environments and experience small temperature changes.

I hope this helps.  Let me know if anything is unclear.

The grouping element, ul, contains the definition associated with a term from a description list. True False

Answers

Answer:

False is your answer

Final answer:

The statement is false. The <ul> element is for unordered lists, while the <dl> elements along with <dt> and <dd> are used for description lists in HTML.

Explanation:

The statement that the grouping element, <ul>, contains the definition associated with a term from a description list is false. In HTML, the <ul> element is used to create an unordered list, typically represented by bullet points. The definitions associated with terms in a description or definition list are contained within a <dl> element. Within this <dl> element, each term is denoted by a <dt> (description term) element, and the corresponding definition is provided within a <dd> (description details) element. It's important to use these specific elements to ensure proper semantics and accessibility on the web.

What element is found in all organic molecules?

Answers

Answer:

The answer is Carbon

Explanation:

Organic compounds are considered to be all those chemical substances that contain some carbon atom in their molecule. Besides carbon, hydrogen is an important element in its constitution.

Carbon molecules unite with each other very easily, developing basic skeletons in all organic compounds. These chains can have different lengths and shapes.

Each carbon atom has a valence of 4 and the bonds in organic compounds are covalent, with the possibility of double or triple bonds.

Organic compounds can also contain other types of chemical elements other than carbon (oxygen, nitrogen, sulfur, etc.) called functional groups. A wide variety of organic compounds are formed from these functional groups.

Which metallic properties are caused by atoms rolling over each other in metallic bonds?malleability and ductility
shininess and ductility
conductivity, malleability, and shininess
ductility, conductivity, and malleability

Answers

Answer: malleability and ductility

Explanation:-

Malleability is the property of metals to be beaten into sheets. Ductility is the property of metals to be drawn into wires.The delocalized sea of electrons enable the metal atoms to roll over each other when stress is applied and thus they can be converted to sheets or wires.

Shininess of metals is because electrons on the surface can bounce back light at the same frequency as the light hits the surface.

When a wire is connected to a metal, the delocalized electrons are drawn to the positive pole and thus helps in the conduction of electricity.

The metallic properties that are caused by atoms rolling over each other in metallic bonds are malleability and ductility.the atoms that are being rolled over are delocalized electrons in the sea of electrons in the metallic bond enable them to roll over when stress is applied.
