Answer:

the cell will lose water

the cell is in a hypertonic solution

Explanation:

The solution is hypertonic while the cell is hypotonic. The cell will lose water to the solution since there are more solutes in the solution compared to the cell. Water moves to solution through osmosis. After osmosis occurs, the condition becomes isotonic.

Oxana [17]

Answer: mitochondria

Cyanide binds with at least one molecule involved in producing ATP. If a cell is exposed to cyanide, most of the bound cyanide is likely to be localized within the mitochondria

Explanation:

Once cyanide ion (CN-) enters the tissues, it gets into the cell mitochondria and binds tightly with cytochrome oxidase, leading to the cessation of transfer of electrons to oxygen. This then makes the electron carriers accumulate in their reduced state, and the generation of high energy phosphate stops.

Thus, the effect of bound cyanide in mitochondria is oxygen deprivation.

30.Water molecules are polar because they have positive and negative ends, rather like little magnets. Most lipids are non-polar (having no charged areas) or only slightly polar, with a very few charged areas. Water mixes with hydrophilic (water-loving) compounds by sticking to their charged groups.

31.Lipids are detected using the emulsion test. This is what happens: The test substance is mixed with 2 cm 3 of ethanol. An equal volume of distilled water is added.

32.In addition to carbon, hydrogen, and oxygen atoms, all proteins contain nitrogen and sulfur atoms, and many also contain phosphorus atoms and traces of other elements. Proteins serve a variety of roles in living organisms and are often classified by these biological roles.

33.amino acids

For example, proteins are composed of monomers called amino acids. They are linked together to form a polypeptide chain, which folds into a three dimensional (3D) structure to constitute a functional protein

34.Peptide Bonds

Section 3.2Primary Structure: Amino Acids Are Linked by Peptide Bonds to Form Polypeptide Chains. Proteins are linear polymers formed by linking the α-carboxyl group of one amino acid to the α-amino group of another amino acid with a peptide bond (also called an amide bond).

35.A polypeptide is a single linear chain of many amino acids (any length), held together by amide bonds. A protein consists of one or more polypeptides (more than about 50 amino acids long). An oligopeptide consists of only a few amino acids (between two and twenty).

What does the skeletal part of the musculoskeletal system do? Why is 'protects the organs of the body' correct?

Alexxx [7]

Answer:

The bones of the skeletal system protect the body's internal organs, support the weight of the body, and serve as the main storage system for calcium and phosphorus. The muscles of the muscular system keep bones in place; they assist with movement by contracting and pulling on the bones.

________ transmit pain that is sharp, nonchronic, and well localized. A. A-delta fibers B. B-delta fibers C. C-fibers D. D-fiber

nydimaria [60]

Answer;

A. A-delta fibers

A-delta fibers transmit pain that is sharp, nonchronic, and well localized.

Explanation;

-The information about touch and pain is transmitted to the spinal cord and brain by primary afferent axons - these are the nerve fibers connected to the different types of receptors in the skin, muscle and internal organs.

-The different nerve fiber groups are; A-alpha, A-beta, A-delta and C-nerve fibers.A-alpha, A-beta and A-delta nerve fibers are insulated with myelin. C-nerve fibers are unmyelinated.

-A-delta nerve fibers carry information related to pain and temperature. A-delta nerve fibers can conduct action potentials as fast as a sprinter in the Olympics.
