17. Which of the following best describes how amino acids affect the tertiary structure of a
protein?
a) The number of amino acids determines the tertiary structure of the protein.
b) The interactions of the different R-groups with other R-groups and with their environment
determine the tertiary structure of the protein.
c) The R-group of the last amino acid that is added to a growing polypeptide chain
determines the next amino acid that is added to the chain.
d) The sequence of the amino acids in the polypeptide chain determines the protein's
primary structure but has no effect on its tertiary structure.

Answers

Answer:

It is B

Explanation:

I had this question on my test last week

The tertiary structure of the protein is determined by the interactions of the different R-groups with other R-groups and with their environment in the protein (Option B).

An R-group (also called variable group) is a side chain that is attached to the α-carbon of the amino acids, the building blocks of proteins.

The linear sequence of amino acids within a protein is the primary structure of proteins.

The second structure of proteins is determined by the pattern of hydrogen bonding in the peptide backbone. The most common secondary structures of the proteins are alpha-helices and beta-sheets.

The protein tertiary structure is the 3D (tridimensional) shape of the protein, which is due to interaction among R groups of amino acids and with their environment.

The most common tertiary structures of the proteins are globular and fibrous structures.

Finally, the quaternary structure of the proteins is determined by the interaction of several protein chains or subunits.

In conclusion, the tertiary structure of the protein is determined by the interactions of the R-groups and with their environment in the protein (Option B is correct).

How does water cause frost wedging?

A
Water attracts lightning, which breaks apart huge boulders into many smaller pieces.

B
Water carries sediment to large rocks, causing them to rub against each other.

C
Water freezes and thaws inside rock cracks, causing them to widen and then split.

D
Water slowly wears down a rock’s sharp edges, leaving behind a smooth surface.

Answers

Answer:

C. Water freezes and thaws inside rock cracks, causing them to widen and then split.

Explanation:

When water gets in the crack at the bottom and freezes, frost wedging occurs.

Frost wedging happens when water gets in crack, freezes, and expands. This process breaks rocks apart. When this process is repeated, cracks in rocks get bigger and bigger (see diagram below) and may fracture, or break, the rock.

How did Concorde fly so high?

Concorde fly so high because the higher it flew, the thinner the air was that it encountered. This consequently led to less drag and fuel burn.

Did the Concorde fly in the stratosphere?

Able to cruise at a near-stratospheric altitude of 60,000 feet at 1350 miles per hour, the plane cut travel times on its routes in half. But speed and altitude were not the only factors that made Concorde so remarkable.

Answers

Prokaryotic cells, which include bacteria, undergo a type of cell division known as binary fission. This process involves replication of the cell's chromosomes, segregation of the copied DNA, and splitting of the parent cell's cytoplasm. The outcome of binary fission is two new cells that are identical to the original cell.
