The R groups of amino acids located on the surface of protein molecules in the interior of biological membranes are ...?

Answers

I believe the answer is A. hydrophobic. Inside the biological membranes are lipids (hydrophobic) molecules. As you may know the membranes are lipid bilayers. In order to place proteins, which are polymers of amino acids, you would need to create an like-to-like environment. The R groups of amino acids will interact with this hydrophobic lipid bilayer environment and will need to display the same characteristics to keep the plasma membrane intact and not cause unwanted disruption. Therefore, R groups of amino acids in biological membranes should be hydrophobic.

The R groups of amino acids located on the surface of protein molecules in the interior of biological membranes are typically hydrophobic. These nonpolar R groups are compatible with the hydrophobic environment of the membrane's lipid bilayer.

Amino acids are the building blocks of proteins and differ from one another by their R groups, or side chains. The chemical properties such as size, polarity, and charge of these R groups determine their interactions and positioning within a protein structure. For amino acids located within the membrane, the R groups must be able to interact with the nonpolar lipid bilayer, which means they are generally hydrophobic. This is because the interior of biological membranes is a nonpolar environment, and hydrophobic R groups will seek to be in this environment to lower the system's free energy. The arrangement of amino acid R groups in proteins contributes to the overall shape and function of the protein, and in the case of membrane proteins, it allows them to stably exist within the lipid bilayer without disrupting the membrane's structural integrity.

a biologist counts the number of zebras in a population each year, and notices an increase in the zebra population. which describes the biologists actions?

graphing

inference

observation

interfacing

Answers

Observation. The biologist has made an observation that the number of zebras has gone up.

The correct answer is observation.

Observation is defined as noticing the process to gain information.The scientists keeps on observing the population of zebra each year and he notices an increase in population and this change was noticed by the scientist because he was observing the change in number of zebra every year.

Is the stomach inferior or superior to the diaphram

Answers

This question doesn't make sense.
The stomach and diaphram are parts of two completely different biological systems.

The stomach is arranged substandard compared to the diaphragm, meaning it is situated beneath the stomach in the human body. This situating isolates the thoracic pit from the stomach pit.

The muscular organ known as the diaphragm divides the thoracic cavity, which is home to the heart and lungs, from the abdominal cavity, which is home to the stomach and other digestive organs. This implies that the stomach is underneath the stomach in the human body. The cardia, fundus, body, and pylorus are the four main parts of the stomach. The cardia associates with the throat and is likewise found mediocre compared to the stomach. The vault formed fundus sits above and to one side of the cardia yet at the same time stays underneath the stomach.

Decomposers play a part in the earth biodiversity

Answers

Decomposers break down dead or decaying organisms, and in doing so, convert their basic materials into forms more useful to the biological community, particularly plants. The main decomposers in the environment include bacteria, fungi and worms. Each of these plays a different, but overlapping, role in decomposition
