igomit [66]

Answer:

Sclera

Explanation:

Sclera is the outer most cover of eye that is fibrous and tough controls both the light entering the pupil as well as the distribution of tear film over the exposed corneal surface.

It provides protection, and is a sensory part of eye, in addition it is also considered as communicating tool.

Match each hazardous waste with its matching description.

Sphinxa [80]

Matching each hazardous waste with its description is shown below :

<u>Hazardous waste description</u>

Asbestos : substance known to cause lung cancer; found in older landfills

Mercury : Substance found in computer monitors that causes brain damage

Cadmium: Hazardous cancer agent found in the batteries of many devices

Lead : Substance from thermostats known to cause reproductive issues

Too much exposure to these hazardous waste always leave a negative effect on the health of individuals, Asbestos are used in the roofing of older buildings and can be found in older landfills. the fiber from asbestos affects the Lungs ( alveoli ) of humans which might lead to lung cancer.

Mercury are used for PC's backlight and also in the mother board of modern computers too much exposure to mercury can lead to brain damage.

Cadmium are hazardous cancer causing agent used in making industrial batteries, prolonged exposure to lead poses several health risk which includes reproductive issues because lead can cut across placenta barrier between a pregnant woman and unborn child.

Hence we can conclude that matching each waste to its description is as

Asbestos : substance known to cause lung cancer; found in older landfills

Mercury : Substance found in computer monitors that causes brain damage

Cadmium: Hazardous cancer agent found in the batteries of many devices

Lead : Substance from thermostats known to cause reproductive issues

consider a molecule of the polymer, polyethylene, and a protein molecule as if they were strings of beads. How would the string

Aleksandr [31]

Answer:

When a macromolecule contains repeated similar sub units of a particular molecule:such a repeated units are called polymers.

Therefore, polyethylene is a micromolecule of repeated subunits called ethylene formed during polymerization..Therefore, the small units joined together to form polyethylene are ethylene.These are alkene hydrocarbons,which are similar in structure with the carbon atoms linked by double bonds.When the Pi bonds of the double bonds breaks. hydrogen atoms forms free covalents bonds in all these sub units.

However, polypeptides is made of of 20 different amino acids, connected by peptides, disulfide and other bonds.Therefore the protein molecules will be different from the polyethylene and polymers. This is because each of the 20 amino acids has different R-groups, and It is this R-groups that determine the functional characteristics displayed by each amino acid sub- units.Therefore, the characteristics of a protein molecule will be determine by the type of Amino acids it contains.

Thus the beads of polyethylene will be the same, but different in proteins

Define and distinguish between diffusion and omosis

Dmitry [639]

Diffusion is the spontaneous movement of substances from a region of high concentration to a region of low concentration.

Osmosis is the passage of water molecules from a high water concentration region through a selectively permeable membrane to a low water concentration region.

In diffusion, selectively permeable membrane is neither required nor involved while in osmosis, it is involved.
