Polypeptides are chains of amino acids. They can coil/fold into different shapes. Some 'R'-groups are either hydrophobic, hydrophilic, or neutral in their charge. Suppose you have a very long polypeptide, where a part of the chain is hydrophobic and another part is hydrophilic. I go ahead and drop this long polypeptide in water and it coils up. How do you think it would coil? Why? What can you infer about the proteins in our bodies regarding this situation
Answer:
The hydrophilic part of the polypeptide chain would be oriented towards the surrounding water while the hydrophobic portion would be arranged away from the water and would make the hydrophobic interior resulting in coiling of the polypeptide chain. The body proteins assume the shapes to organize their hydrophobic parts away from the watery fluid.
Explanation:
Amino acids are the monomers of proteins. Each amino acid, present in proteins, has a central carbon atom. Four functional groups are attached to the central carbon atom of amino acid. These are the carboxyl group (COOH), amino group, a hydrogen atom (H) and a side chain (called R group). Amino acids differ from each other for the side chain present in them. Based on the nature of the side chain, amino acids are hydrophobic or hydrophilic or neutral. Sidechains of some amino acids are charged and have positive or negative charges on them.
The extracellular fluid of the body is a watery medium. Blood also has liquid plasma that is 99% water. The intracellular fluid, called cytosol, is also a water-based liquid.
The hydrophilic side chains of the amino acids interact with the watery surroundings. They can make hydrogen bonds with the water. The charged hydrophilic R groups make electrostatic interactions with the surrounding medium. The hydrophobic R groups of the amino acids tend to arrange themselves away from the watery medium. This makes the part of the polypeptide chains with hydrophobic amino acids to fold so that these R groups are oriented away from the water.
Similarly, when a long polypeptide chain is dropped in the water, the hydrophobic R groups are arranged away from the water while the hydrophilic ones are arranged towards the surface of the chain facing the water. It is done to adopt a stable shape where maximum attraction forces are established.
Identify the plant tissues in the three images.
A
B.
C
I originally asked for the images but I will give it my best shot at answering your question without them! :D
There are only three types of plant tissues:
1. Dermal
2. Ground
3. Vascular
The dermal tissue is the outside of the plant's root, stem, or leaf, A.K.A the the skin. If you're looking at a circular image, what ever is pointing to the outside ring of the stem is the dermal tissue.
The ground tissue is the flesh of the plant that is inside the dermal tissue. It surrounds the vascular tissue in the middle of the stem. Whatever letter is pointing to the wide, fleshy ring, that is touching the dermal tissue is the ground tissue. It is the largest part of a plants stem, roots, or leaves.
Lastly, the very inner ring or rings of the plant is the vascular tissue. It's made up of xylem and phloem. This can be found in many different places depending on the part of the plant, but what you're looking for is tiny circles within the ground tissue. If you're looking at the roots, you will see one circle in the very center of the plant, surrounded by ground tissue. If you're looking at the leaves, you will see one circle as well, and additionally other tiny circles throughout the ground tissue in each wing. Lastly, if you're looking at the stem, you'll see a circle of tiny circles within the ground tissue. These small circles are all vascular tissue.

The dermal tissue is the outermost layer of cells that covers the plant. It is responsible for protecting the plant from the environment. The vascular tissue is a system of tubes that transports water and nutrients throughout the plant. The ground tissue is the tissue that makes up the bulk of the plant. It is responsible for photosynthesis, storage, and support.
In the image, the dermal tissue is the thin layer of cells that covers the surface of the leaf. The vascular tissue is the network of tubes that runs through the leaf. The ground tissue is the bulk of the leaf, and it is made up of cells that contain chloroplasts.

Image 3:
The xylem is a type of vascular tissue that transports water and nutrients from the roots to the rest of the plant. The phloem is another type of vascular tissue that transports sugars from the leaves to the rest of the plant. The ground tissue is the tissue that makes up the bulk of the plant. It is responsible for photosynthesis, storage, and support.
In the image, the xylem is the dark brown tissue that runs through the center of the stem. The phloem is the lighter colored tissue that surrounds the xylem. The ground tissue is the bulk of the stem, and it is made up of cells that contain chloroplasts.

C. hydrogen chloride dissolving in water
D. table sugar dissolving in water
Answer:
I'll say B cause the Nacl ion breaks down and get surrounded by hydrogen and hydroxyl ion
Table salt dissolving in water is the example of dissociation.
What do you mean by dissociation?Dissociation is the process by which chemical molecules (or ionic compounds such as salts, or complexes) break down into simpler constituents such as atoms, ions or radicals, usually in a reversible manner.
Moreover, the dissociation of water is an equilibrium reaction in which one water molecule donates its proton to another water molecule.
Salts that are soluble in water dissociate into their ions and are electrolytes. Salts that are insoluble or only slightly soluble in water form very few ions in solution and are nonelectrolytes or weak electrolytes.

A tapeworm needs to eat food that is already digested, so it lives in the intestines of a dogfish shark and derives nourishment from the shark. As a result of the tapeworm infestation, the shark is weakened and more vulnerable to disease and predation.
What type of relationship is this?
Answer:
parasitism
Explanation:
This is an example of parasitism, because the shark is not benefitting from this relationship, only the tape worm, making this relationship parasitism.
A tapeworm living in the intestines of a dog fish shark and derives nourishment from the shark due to this reason the shark is weakened and more vulnerable to disease and predation. Thus, this type of relationship is known as parasitism.
What is parasitism ?The term parasitism is defined as a relationship among two species in which one organism, that is parasite, survive inside another organism, that is host, that causes harm, and survived.
Tapeworms and barnacles are found attached to the insides part of the intestines of animals like cows, pigs,etc.
They eat the food of animals inside which they live and weakened the animal.

Why is oceanic crust younger than continental crust?
Answer:What is the best explanation for why oceanic crust is subducted by continental crust?
The continental crust is also less dense than oceanic crust, although it is considerably thicker. As a consequence of the density difference, when active margins of continental crust meet oceanic crust in subduction zones, the oceanic crust is typically subducted back into the mantle.
Explanation:Why oceanic crust is younger than Continental?
Through mantle convection, the rich minerals of the mantle may be ultimately “recycled” as they surface as crust-making lava at mid-ocean ridges and volcanoes. Largely due to subduction, oceanic crust is much, much younger than continental crustWhy is the theory of plate tectonics so important to geologists?

A cell’s digestive enzymes are enclosed in a membrane-bound organelle. How can these molecules function in the cell?
Answer:
A fundamental task of proteins is to act as enzymes—catalysts that increase the rate of virtually all the chemical reactions within cells. Although RNAs are capable of catalyzing some reactions, most biological reactions are catalyzed by proteins.
Explanation:
Enzymes perform the critical task of lowering a reaction's activation energy—that is, the amount of energy that must be put in for the reaction to begin. Enzymes work by binding to reactant molecules and holding them in such a way that the chemical bond-breaking and bond-forming processes take place more readily

Iron, water, and sugar are examples of matter that are nutrients.
True or false
Answer:
false
Explanation:
water is just good for you and some sugars are good
Iron, water, and sugar are examples of matter that are nutrients. So the statement is true.
What are nutrients?
The substances in food known as nutrients give us the energy needed for development, repair, and other vital living activities. Although not all nutrients are energy-producing, they are all required in one way or another. There are two groups of these nutrients:
macronutrients, which the body needs in huge quantities.micronutrients, which the body needs in minute amounts.
The environment may provide the aforementioned nutrients. Macronutrients give a living thing the energy it needs to run its metabolic system. They offer enormous energy that can be processed and used to produce energy. Fats, proteins, and carbs are examples of macronutrients.
Micronutrients supply the necessary building blocks for metabolism to function. To regulate bodily processes, they also create new tissues and replace ones that have been destroyed. Calcium, iron, vitamins, minerals, iron, and vitamin C are examples of micronutrients.
Therefore, iron, water, and sugar are examples of matter that are nutrients.
