The hydrocarbons' surface.

Because the covalent link that exists between hydrocarbon surfaces is different from the surfaces to which the salamander can cling, the salamander has difficulties adhering to these surfaces.

The hydrogen bond is the bond that exists between hydrogen and a bigger molecule like nitrogen or oxygen, whereas a covalent bond includes sharing electrons.

<h3>What Are Hydrocarbons and What Do They Do?</h3>

Crude oil, natural gas, and coal are all examples of hydrocarbons, which are organic compounds made of hydrogen and carbon. The world's primary energy source and a highly flammable substance, hydrocarbons. Petrol, jet fuel, propane, kerosene, and diesel are only a few of its uses.

at short focusing distances, ciliary muscles contract. what effect do these contractions have on the suspensory ligaments?
True [87]

At short focusing distances, ciliary muscles contract causing the suspensory ligaments to tighten.

The ciliary muscle is an integral muscle of the eye that is constructed as a ring of smooth muscle in the middle layer of the eye, the uvea (vascular layer). It regulates the passage of aqueous humor into Schlemm's canal and governs accommodation for observing objects at different distances.

A suspensory ligament is a ligament that provides support to a body part, particularly an organ. The suspensory ligament protects the fetlock from hyperextension (i.e., falling too low) during exercise. The ligament begins in both the fore and hindlimbs at its connection to the back of the upper cannon bone.

When the ciliary muscle relaxes, its diameter increases; when the suspensory ligaments tighten, the lens becomes thinner. This occurs when concentrating on a celestial object. When the ciliary muscle contracts, the lens becomes much more circular and has more focusing power because the pressure on the zonular fibers is reduced. When the ciliary muscles relax, these fibers contract, pulling the lens out and creating a flatter shape with less focusing power

In what way do the membranes of a eukaryotic cell vary?
ser-zykov [4K]

Answer:

The Answer is Letter E.

Explanation:

<em>The way membranes of a eukaryotic cell vary is certain proteins are unique to each membrane. </em>

The eukaryotic cells also contain other membrane-bound organelles such as mitochondria and the Golgi apparatus, and in addition, some cells of plants and algae contain chloroplasts. Unlike unicellular archaea and bacteria, eukaryotes may also be multicellular and include organisms consisting of many cell types forming different kinds of tissue.
