<h3>According to the given statement:</h3>

An organism must typically meet two conditions in order to become fossilized:

1) Organisms require hard parts like shells, teeth, cartilage, and bones.

(2) The organic material needs to be buried as soon as possible in a place that is oxygen-free and protected from scavengers.

<h3>Exactly who is a scavenger?</h3>

An organism known as a scavenger primarily consumes decaying biomass, such as animal or plant matter that has gone bad. A lot of scavengers are carnivores, which are creatures that consume meat.

<h3>What are four examples of scavengers?</h3>

Among the land scavengers are wolves, hyenas, jackals, and bears. Scavengers can be found in the air, including vultures, crows, ravens, and condors. In water, scavengers include lobsters, crabs, and several shark species.

Water supplies are treated with chlorine to kill pathogens. chlorine reacts well with many other chemicals and bacterial cells b

expeople1 [14]

Answer:

Legionella tends to form biofilms and infect other microbial cells as intracellular pathogens.

Explanation:

The Legionella genus of the bacteria is a group of gram-negative bacteria that can cause legionnaires disease.

The<em> Legionella pneumophila</em> is a species of this genus which can cause legion pneumonia. The bacteria lives in the freshwater and is resistant to chemical treatment like chlorine and the biocide treatment.

The reason for this resistance is since this species form a polysaccharide layer around the colony of the bacteria which is resistant to these treatments and also the bacteria prove parasitic to the protozoans which feed on these bacteria.

Thus, the selected option is the correct answer.

Why would it be expected that a swordfish would exhibit higher methyl mercury levels than a tilapia? (site 2)

kirill [66]

Answer:

Answer is explained below;

Explanation:

Mercury is a liquid metal that is released into the environment by both natural processes such as volcanic activity, weathering of rocks, etc and human activities such as waste materials from factories. The mercury that reaches the ocean and other water sources is converted into methylmercury by bacteria. Methylmercury is a neurotoxin that interferes with the nervous system and is easily absorbed by the human body.

The methylmercury is taken up by planktons. Small fishes consume large quantities of plankton. Tilapia is a small, short-lived freshwater fish. The methylmercury level in tilapia is lower than that of other fish. When large, long-living predatory fishes such as tuna, shark, king mackerel, swordfish, etc consume many smaller fish with low mercury levels, this causes accumulation of methylmercury at extremely high levels in their tissues over time i.e., the amount of mercury in such bigger fish biomagnifies.

So large, long-lived predators like swordfish and shark often have the highest methyl mercury levels than a small, short-lived tilapia.

When water falls from clouds to Earth's surface, this is known as transpiration condensation evaporation precipitation

Elza [17]

Your answer is precipitation: <span>Any or all of the forms of water particles, whether liquid or solid, that fall from the atmosphere (e.g., rain, hail, snow or sleet). It is a major class of hydrometeor, but it is distinguished from cloud, fog, dew, rime, frost, etc., in that it must fall. It is distinguished from cloud and virga in that it must reach the ground.(Grammarly)</span>

What is the polaris rule and how does it help you find places on earth?

juin [17]

Answer:Polaris is directly overhead (i.e. at zenith) at the North Pole and at the horizon for an observer at the equator. The rule of thumb for the altitude of Polaris is that the altitude of Polaris equals your latitude on Earth.
