Exceptions to cell theory are

1. Viruses: They contain only genetic material. Protoplasm is absent. Active or show signs of life only in a living cell

2. Coenocytic organisms: Vaucheria and fungi belonging to Phycomycetes are filamentous with continuous protoplasm and many nuclei, that is the filament is not divided typically into cells, with single nucleus that undergo division periodically.

Lamarck believed that organisms could acquire characteristics during their lifetime, that they could pass down to their offspring, but Darwin did not believe these traits could be passed down. Darwin proved that the species adapted to their environment through natural selection. Meaning only the one that could adapt to the changes would survive.

Pros and cons of nuclear power?

Ivan

Some advantages

Produce relatively low amounts of carbon dioxide (CO2).Well-developed engineering knowledge. Single plant can generate high amount of power.

Some disadvantages

Radioactive waste, an extremely dangerous byproduct, needs careful monitoring for thousands of years. Accidents may create havoc on a large scale.Uranium, the primary energy source, is estimated to be available only for the next 30 to 60 years without the use of high-efficiency breeder reactors.

Match each hazardous waste with its matching description.

Sphinxa [80]

Matching each hazardous waste with its description is shown below :

Hazardous waste description

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

Random mutations can occur in an organism's DNA, causing traits that are different from other organisms in that species. Sometim

Lelechka [254]

-The mutation could make it easier for an organism to obtain food.
-yes, a correct anwer!

-The mutation could make an organism need more food.
-no, this would make it harder for the organism to survive

-The mutation could improve the organism's sight.
-yes! better sight means more information, which is beneficial

- The mutation could let the organism run faster.
-running faster means advantage over pray and predator - also a correct answer

so all are correct except on the second one.
