Hydrophobic R groups are most likely to be found in the center of the protein structure because during protein folding, the hydrophobic R groups of nonpolar amino acids are positioned in the interior of the protein, hidden from the water-based outer environment.
Explanation:The sections of the embedded protein chain that are most likely to contain amino acids with hydrophobic r-groups are typically those that are embedded in the center of the protein structure. This is due to the hydrophobic (water-repelling) nature of these r-groups. Proteins often fold in such a way that hydrophobic parts are tucked away from the aqueous environment, into the protein interior.
During protein folding, hydrophobic R groups of nonpolar amino acids tend to be positioned in the interior of the protein, hidden from the water-based outer environment, whereas R groups of polar amino acids, which are hydrophilic (water-attracting), tend to be on the outside of the protein. This process is guided by hydrophobic interactions.
For instance, in alpha-helix and ß-pleated sheet secondary structures of proteins, R-groups protrude out from the protein chain. The exact positioning of these r-groups, either buried in the interior or exposed to the surface, depends on their hydrophobic or hydrophilic nature.

Sometimes a suffix functions independently as a medical term. give two examples of suffixes that are also terms, and explain how they are used.
The answer would be –genesis and –gram.
Suffixes that have a Greek or Latin roots and that are used to combine with other words or parts of words are not called suffixes, these kind of affixes are called combining forms.
One combing form is –genesis.
As an independent medical term, this means the origin of something in medicine. When a doctor talks about the genesis of a contagion, he or she is speaking of the point of origin of a contagion.
-genesis used as a suffix, can indicate a particular process or pathogen. Example is parthenogenesis.
One combining form is –gram.
As an independent medical term, gram indicated the metric weight of an object as a unit of mass. If nurses talk about how much serving of food, they are talking about it in grams.
-gram signifies something written down. Example is pictogram.
In medical terminology, -itis and -oma are examples of suffixes that are also used independently as terms. -itis indicates inflammation and -oma represents a tumor or neoplasm.
Explanation:In medical terminology, there are certain suffixes that also function independently as terms. Suffixes in medicine provide specific information about the meanings of root words.
One such example is -itis, which is a suffix used to indicate inflammation. When 'iti's is used independently, it refers to a generalized inflammation without specifying the affected part of the body.
Another example is -oma. It's usually used as a suffix to indicate a tumor or neoplasm. However, 'oma' can also be used alone to represent a tumor in a general sense.

A new element has been discovered. Newelementium has 40 more protons than radon. It also has the same number of protons and neutrons. What would newelementium’s atomic number and atomic mass be? (Use the periodic table)
Answer:
Atomic number would be 126 and atomic mass 252.
Explanation: The atomic number is the number of protons in the nucleus of an atom. This number is the position they occupy in the periodic table.
On the other hand, the atomic mass is obtained by adding the number of protons and neutrons of a given nucleus.
Consequently, if Newelementium has 40 more protons than radon and acoording to the periodic table radon has 86 protons, the atomic number is calculated as follows:
1. 86 + 40 = 126
Newelementium would have 126 protons, therefore its atomic number would be 126.
Since Newelementium has 126 protons and the same number of neutrons, its atomic mass would be:
2. 126 (protons) +126 (neutrons) = 252
Newelementium atomic mass would be 252.

Choose which tissue type likely functions to add support to an organ.
The connective tissue, specifically types such as cartilage and bone, is designed to provide support and maintain the structural integrity of organs. They offer flexible and rigid frameworks respectively and withstand various physical stresses to maintain organ stability.
Explanation:Tissue Type That Functions to Add Support to an Organ
The connective tissue is the type that likely functions to add support to an organ. Within the human body, there are various types of connective tissues that each play a crucial role in supporting and maintaining the structure of organs. A particular form of supportive connective tissue includes both cartilage and bone. Cartilage provides a flexible yet strong framework that can resist compression, making it an essential component in joint areas and the growing portions of bones. Bone, on the other hand, offers a rigid structure due to its mineralized matrix, allowing for the protection of internal organs and enabling posture maintenance.
Dense connective tissue proper, also functions as supportive tissue. It is richer in fibers and is found in tendons and ligaments where strength along one axis is especially important. It is also seen in organ capsules and artery walls where strength in multiple directions is needed.
The supportive role of connective tissues is integral to the functionality of organs, ensuring they can withstand various physical stresses and maintain their shape. Knowledge of how these tissues contribute to organ stability is a critical aspect of understanding human anatomy and physiology.

The instructions for growth and development are in ________.
The _______________ completely covers the surface of the protoplasm.
The plasma membrane, or plasmalemma, is the structure that completely covers the surface of the protoplasm, serving as a protective barrier and regulating the passage of substances into and out of the cell.
The structure that completely covers the surface of the protoplasm is the plasma membrane, or plasmalemma. This membrane serves as a protective barrier that regulates the passage of substances into and out of the cell.
In some protozoans, a structure called the pellicle is present just inside the plasma membrane, providing additional rigidity.
Underneath the plasma membrane, ectoplasm and endoplasm form distinct layers of cytoplasm that contribute to complex cell shapes.
The cell wall is another structure described in plant, fungal, and some protistan cells; it is external to the plasma membrane and offers protection, support, and shape to the cell, but it is not the surface that covers the protoplasm in animal cells such as protozoans.
Instead, in protozoans, it's the plasma membrane that completely covers the protoplasm.

If a person is severely dehydrated, their extracellular fluids will become hypertonic to the intracellular fluid. what do you predict will happen to the person's cells
In response to severe dehydration causing the extracellular fluid to become hypertonic, cells will lose water, causing them to shrink. This process is due to osmosis, which seeks to balance the solute concentrations inside and outside the cells. This can lead to dysfunction of the cells.
Explanation:If a person is severely dehydrated, their extracellular fluids will become hypertonic to the intracellular fluid. This results in a higher concentration of solutes in the extracellular fluid when compared to the intracellular fluid. Given this hypertonic situation, water within the cells will move out to the extracellular environment in an attempt to balance the concentration of solutes, a process known as osmosis.
This movement of water out of the cells can lead to the cells shrinking or becoming dehydrated. In extreme cases, cells may cease to function normally and in severe cases this can be harmful or potentially fatal if not promptly addressed. Living organisms usually strive to maintain a state of isotonicity, where the solute concentration is the same in and outside of cells preventing such drastic movements of water.
