What is unusual about the peptide bond compared to the other covalent bonds that form the polypeptide backbone?
A) The side chains only face internally, excluding them from interacting with water.
B) The single bonds on either side of the peptide bond cannot rotate, making the peptide backbone very rigid.
C) There is an amino group on one end of the backbone and an aldehyde group on the other.
D) Peptide bonds behave like double bonds in terms of stability and lack of movement of atoms around the bond.
Answers
Answer:
D
Explanation:
A peptide bond is also known as amide bond which is formed between two amino acid molecules. An amino acid contains two functional groups; a carboxylic acid group and an amino group. ... The resulting linkage between two amino acid molecules is called a covalent bond.
The unusual about peptide bond is ( D ); Peptide bonds behave like double bonds in terms of stability and lack of movement of atoms around the bond
The polypeptide is the Non-R group of amino acids polymers that consists of
N-C-C-N-C-C-N , and the polypeptide backbone allows for the backbone to backbone hydrogen bonding and it acts as a contributor to the secondary structure of the protein.
also the linkage between amino acid molecules is called a covalent bond.
Hence the unusual about the peptide bond when compared to other covalent bonds that form the polypeptide backbone is Peptide bonds behave like double bonds in terms of stability and lack of movement of atoms around the bond

Chris wrote a few steps to describe how carbon circulates between the ground and living organisms.
Step 1. Trees absorb carbon dioxide in the air and use it to make their own food using photosynthesis.
Step 2. When plants or animals die, they are broken down by decomposers and their carbon returns to the soil.
Step 3. Carbon stays in the ground for long-term storage as fossilized carbon.
If step 1 is removed, which statement best describes the effects of this missing step on the carbon cycle?
More carbon is stored in the ground for long-term storage.
Less carbon is available for plant and animal growth.
More carbon is stored in plants instead of the ground.
There are more fossil fuels available for energy use.
Answers
Answer: i think it is less carbon is available for plant and animal growth. if not i'm sorry
The carbon cycle involves the circulation of carbon and its compound in the earth's spheres. Removal of step 1 results in decreased carbon for animals and plants. Thus, option b is correct.
What is the carbon cycle?The carbon cycle is a cyclic movement of carbon in various spheres between the biotic and the abiotic factors. It involves the biosphere, atmosphere, geosphere, and other spheres. Carbon comes from the atmosphere in the form of carbon dioxide.
This carbon dioxide is used by plants to make food in the form of sugar and is consumed by animals as an energy source. If trees utilizing carbon dioxide are removed then less carbon will be available for cellular respiration.
Therefore, option B. removal of step 1 from the process results in less availability of carbon from animals and plants.

Question 3 options:
Plant cells have a cell wall instead of a plasma membrane.
Proteins are embedded in the plasma membrane and contribute to its function.
The exterior of a phospholipid bilayer is hydrophilic, and the interior is hydrophobic (see figure above).
The plasma membrane regulates the movement of molecules and ions into and out of the cell.
Answers
Answer:
The plasma membrane regulates the movement of molecules and ions into and out of the cell.
Explanation:
Cell membranes protect and organize cells. All cells have an outer plasma membrane that regulates not only what enters the cell, but also how much of any given substance comes in. Unlike prokaryotes, eukaryotic cells also possess internal membranes that encase their organelles and control the exchange of essential cell components. Both types of membranes have a specialized structure that facilitates their gatekeeping function.
The true statement about a cell’s plasma membrane is that the plasma membrane regulates the movement of molecules and ions into and out of the cell. The correct option is D.
What is a plasma membrane?The plasma membrane or cell membrane is the outer covering of the cell. It is made up of lipids and proteins. Cell membranes serve to separate and group cells. Every cell has an exterior plasma membrane that controls both what and how much of any given material enters the cell.
Eukaryotic cells, unlike prokaryotes, have internal membranes that enclose their organelles and regulate the exchange of vital cell components. Both kinds of membranes have a unique structure that makes it easier for them to perform the gatekeeping job.
Thus, the correct option is D. The plasma membrane regulates the movement of molecules and ions into and out of the cell.
