Answers

Answer:

Yes

Explanation:

Cells are composed of water, inorganic ions, and carbon-containing (organic) molecules. Water is the most abundant molecule in cells, accounting for 70% or more of total cell mass. Consequently, the interactions between water and the other constituents of cells are of central importance in biological chemistry.

Why do cultural universals exist?

Answers

Cultural universals (elements of a culture that exist in every society such as food, religion, language, etc.) exist because all cultures have basic needs and they all develop common features to ensure their needs are met. ... Countercultures reject the norms of society and replace them with their own.

Cultural universals exist because all cultures have basic needs and they all develop common features to ensure their needs are met.

What do you mean by cultural universals?

A cultural universal is an element, pattern, trait, or institution that is common to all known human cultures worldwide. Taken together, the whole body of cultural universals is known as the human condition.

There are 10 basic elements of every culture: geography, language, family, FCTS (food, clothing, transport, shelter), economics, education, politics, technology, VBR (values, beliefs, rituals), and cultural expression.

Examples of elements that may be considered cultural universals are gender roles, the incest taboo, religious and healing ritual, mythology, marriage, language, art, dance, music, cooking, games, jokes, sports, birth and death.

All proteins have amino acids as their building blocks. Even though there are only 20 amino acids, there are more than a million different proteins, and each works in a unique way. Which of the following conclusions about a protein's function is best supported by this information? (4 points)

Group of answer choices

The amino acids combine in different ways to form proteins with different shapes, and this affects which molecules can bind to it, which in turn directs the protein's function.

The amino acids reproduce in different ways, and this allows them to form many different proteins, which in turn directs the protein's function.

The shape of a protein determines what amino acids it is made of and what types of reactions it can be used for, which in turn affects the protein's function.

The shape of a protein dictates when a protein will break apart into amino acids, which in turn affects the protein's function.

Answers

Answer:

The amino acids combine in different ways to form proteins with different shapes, and this affects which molecules can bind to it, which in turn directs the protein's function.

Explanation:

There are many different combinations for amino acids to bind, and all of the different combinations have very different structures.

Additionally, the unique shapes of all proteins determine the exact function that they have.

These different shapes will also affect what molecules can bind to it.

The secondary structure of a polypeptide is produced by bonds between amino
acids.
Describe how.

Answers

The order in which the amino-acids are placed within the polypeptide determines the tertiary structure and therefore the function of the given protein. Amino acids have different functional groups like methyl(CH3), phenyl(C6H5). Those functional groups can interact with molecules like glucose determining reactions, the proteins that catalyze reactions are called enzymes. Other functional groups of amino acids can be the sulfate groups. For example, insulin has 2 polypeptide chains(Chain A has 21 amino acids, and chain B, 30). Between the two polypeptide chains, 2 disulfide bonds form altering its shape.

The  secondary structure of a protein is generated by hydrogen bonds between atoms of the polypeptide backbone.

A hydrogen bond is an intramolecular attraction between a hydrogen atom in one molecule and an electronegative atom (e.g., oxygen) of another molecule.

The most common types of secondary structures in proteins are alpha helices and beta sheets.

In alpha helices, the carbonyl group of one amino acid is bonded to the amino group of another amino acid spaced four residues apart in the polypeptide chain.

In beta-sheets, different regions of the polypeptide line up next to each other, thereby these protein regions interact by hydrogen bonds.

In conclusion, the secondary structure of a protein is generated by hydrogen bonds between atoms of the polypeptide backbone.
