Answer:

The easiest one to correct would most likely be Class V, since in this type of mutation, the only problem or abnormality is the production of insufficient amounts of the needed CFTR.

Explanation:

Mutation Classes

Class I - Gene contains a stop signal that prevents CFTR from being made.

Class II - CFTR is made, but does not reach the cell membrane

Class III - CFTR is made and in the right place, but does not function normally

Class IV - Channel does not move substances efficiently or at all

Class V - CFTR is made in smaller than normal quantities

Answer:

Theories can be created by just one person

Explanation:

What normally happens is that one person creates a theory, and as years go by new research comes out further advancing or modifying a theory. The theory then is created by many people. Which overall still means that theories can be created by just one person.

Answer: This statement ("antibiotics kill bacteria so they must kill healthy human cells too and they must be avoided at all costs!") is wrong and can be proven to be so in the following explanation about the mode of actions of antibiotics.

Explanation:

Antibiotics are drugs which are used for the treatment of diseases caused by bacteria microorganisms. According to their mode of action, they can either be bactericidal or bacteriostatic.

Bacteriostatic antibiotics work by binding to enzymes needed by bacteria to build proteins essential for their own growth and reproduction. Atypical example is the antibiotics, sulfonamide. This drug acts by inhibiting a critical enzyme called dihydropteroate synthase which are specific to the metabolic pathway of the bacteria cells for the synthesis of folic acid. This causes the bacteria to stop growing. Together with the actions of the immune system, the bacteriostatic actions of the antibiotics can effectively stop am infection without affecting the host cells.

No, because bears kill to get their food. They eat fish and they kill the fish to get them. If they left the fish carcass, decomposers would eat it. The bear makes the food for the decomposers, but it is not a decomposer itself... Does that make sense?

Messenger ribonucleic acid (mRNA) is the single-stranded biological molecule that resembles the hereditary sequence of the gene and is needed for coding the proteins molecules essential for cell function and growth.

Transcription is the process that occurs in the nucleus.

Therefore, transcription results in the formation of the mRNA.

Explanation:

I don't have access to your model, although I'm sure it's beautiful. Fortunately, this question can be answered without one.

A strand of DNA is a polymer consisting of monomeric nucleotide units. The nucleotides that are found in DNA are distinguished by their nucleobases: adenine (A), thymine (T), guanine (G), and cytosine (C). Each nucleotide in DNA is made up of a single nucleobase, a sugar (deoxyribose), and a phosphate group. These nucleotides form extremely long chains comprising phosphate-sugar linkages (covalent, phosphodiester bonds).

In native, double-stranded DNA, you have of these chains (or strands) arranged side-by-side such that the nucleobases on one chain are faced directly across corresponding nucleobases on the other chain, which enables hydrogen bonding between the bases.

There is a "rule" regarding which bases form hydrogen bonds with one another (Chargaff's rule): adenine with thymine and guanine with cytosine.

What does this have to do with the width of the DNA molecule?

The four nucleotides can be structurally classified into two categories: pyrimidines and purines. For our purposes, we only need to know that pyrimidines are six-membered rings and purines are a fusion of a six- and five-membered ring (basically, purines are pyrimidines attached to a five-membered ring). Thymine and cytosine are pyrimidines, and adenine and guanine are purines.

So, geometrically, adenine and guanine are larger (and, thus, "wider") than thymine and cytosine since adenine and guanine contain an extra ring. But remember our base-pairing rules: In native DNA, adenine (two rings) on one strand pairs up with thymine (one ring) on the other strand, and guanine (two rings) pairs up with cytosine (one ring) on the other strand.

Because there's a 1:1 ratio between A:T and G:C in double-stranded DNA, the DNA molecule consists of complementary base pairs that, in any given composition of, has equivalent widths. Put simply, the A=T pair has the same width as a G≡C pair because both base pairs are between one pyrimidine and one purine.

DNA (Deoxyribonucleic acid) is composed of four nucleotides, namely, adenine, guanine, cytosine, and thymine.

Thus, the relative pairing of the purine and pyrimidine with each other keeps the width of the DNA constant.

Coral reef fish are a significant food source for over a billion people worldwide. Many coastal and island communities depend on coral reef fisheries for their economic, social, and cultural benefits. But too much of a good thing can be bad for coral reefs. Download this infographic | Infographic Text

Coral reef ecosystems support important commercial, recreational, and subsistence fishery resources in the U.S and its territories. Fishing also plays a central social and cultural role in many island and coastal communities, where it is often a critical source of food and income.

The impacts from unsustainable fishing on coral reef areas can lead to the depletion of key reef species in many locations. Such losses often have a ripple effect, not just on the coral reef ecosystems themselves, but also on the local economies that depend on them. Additionally, certain types of fishing gear can inflict serious physical damage to coral reefs, seagrass beds, and other important marine habitats.

Coral reef fisheries, though often relatively small in scale, may have disproportionately large impacts on the ecosystem if conducted unsustainably. Rapid human population growth, increased demand, use of more efficient fishery technologies, and inadequate management and enforcement have led to the depletion of key reef species and habitat damage in many locations.

Answer:

1. Only small uncharged molecules can diffuse freely through phospholipid bilayers (Figure 2.49). Small nonpolar molecules, such as O2 and CO2, are soluble in the lipid bilayer and therefore can readily cross cell membranes. 2. Diffusion through a permeable membrane moves a substance from an area of high concentration (extracellular fluid, in this case) down its concentration gradient (into the cytoplasm). 3. Objects change their motion because unbalanced forces act on them. There are four main factors that affect the motion of objects. These factors are force, friction, inertia, and momentum.

Answer:

Examples include steroids and Vitamins

Phospholipids ,as the name implies fall under the category of lipids. Phospholipids have a hydrophilic "head" which has a strong attraction to water molecules.The hydrophilic head contains a phosphate group which allows for reactivity with water molecules.

Phospholipids also contains two hydrophobic "tails" which has a strong repulsion to water. The tails are derived from fatty acids and are joined by a glycerol molecule. These compounds are less reactive to water molecules .

These properties make phospholipids to be soluble in both water and oil which favors the movement of molecules such as Steroids and Vitamins in and out of the cells through the process called Diffusion.

The direction of movement depends on the concentration of molecules as they usually move from a region of high concentration to a region of lower concentration to ensure there is equilibrium and proper functioning of cells.
