Answer:
Explanation:
One major characteristic used to identify bacterial species is by Gram staining. This makes bacteria to be classified into two broad classes; Gram positive bacteria (appear purple after stain) and Gram negative bacteria (appear pink after stain).
Another characteristic used is the presence or absence of capsule.
Other characteristics include there motility (which can be due to the presence of flagella), bonding tendency (which can be individually or in pairs) and also pathogenic bacteria can be classified as intracellular or extracellular bacteria.

the difference between scientific theory and law.
Answer:
a theory cannot become a law
Explanation:
the difference between a scientific theory and a scientific law because a theory is an in depth explanation of an observed phenomenon. a law is a statement about an observed phenomenon or an unifying concept (i.e.: newtons law or gravity - no explanation on how it works or what it is just that it exists.)

Gram , coccus, chains, catalase -, gamma hemolysis, glucose fermentation, grows slightly on MSA (salt tolerant) other test: mannitol fermentation test results: >80% which other test(s) are recommended to further increase the accuracy of your identification This organism is .
Answer:
The name of the test which can increase the accuracy of the identification of the organism is Coagulase testing.
Explanation:
Given the points stated in the question, the organism most likely under scrutiny here is Staphylococcus Aureus. Science has shown that it is the most harmful of all of the many different staphylococcal bacteria that there is.
The best test for differentiating and identifying Staphylococcus Aureus apart from other types of other Gram-positive cocci is the coagulase test.
The coagulase test checks to see if the microbe can produce an exoenzyme called coagulase.
Coagulase - an exoenzyme, is usually produced by bacteria. This enzyme triggers the coagulation of blood or plasma.
Only the pathogenic or disease-causing forms of staphylococcus can produce this enzyme. The enzyme is qualified by the suffice "exo" because the enzyme is secreted externally and not internally. Also, its functions are external, not internal.
The Coagulase testing is of two types:
The Slide TestThe Tube TestIt is usually safer to use the test tube method. If one must rely on the slide test, the results must be read quickly as it is prone to false positives.

A predatory fish evolves adaptations that make it more adept at catching smaller fish. In turn, the smaller fish evolve means to be evasive, leading to more selection on the predators to be still better able to catch their prey. The interaction between the two species is an example of a(n)
Answer:
an evolutionary race (i.e., coevolution)
Explanation:
Coevolution is a phenomenon where two or more species affect each other's evolution through the mechanism of natural selection. During coevolution, species start an evolutionary race, where one species adapt and change (i.e., evolve) in response to another species, thereby countering the adaptive effects of the first one. An example of coevolution is the evolutionary race between predators and preys, like the example above.
The interaction between the two species is an example of a(n) coevolution. To understand more about it......
Arms raceIn the coevolutionary arms race, there is selection pressure on both prey and predator. The predator evolves to catch the prey, and mutually the prey evolves to escape the predator. These arms race can be seen in Cenozoic mammals, where the size of the brains of predators and prey increased relatively over time. As the brain size of predators grew to become smarter to catch prey, the brain size of prey also grew to become smarter and able to escape predators. This process is called climbing coevolution, where predator adaptations are neutralized by prey adaptations, with no advance occurring. As a result, current predators are no better at capturing their prey than ancestral predators. Different from what happens in the evolutionary process, where evolution generates organisms that are better adapted than others
With this information, we can say that the coevolution of predator and prey is common in nature, and determines the survival of these species involved.

Describe the water cycle in a brief paragraph. Use terms that you know are associated with the water cycle.
Answer:
The water cycle or hydrologic is a continuous cycle where water evaporates, travels into the air and becomes part of a cloud, falls down to earth as precipitation, and then evaporates again. ... As clouds move up and over mountains, the water vapor condenses to form precipitation and freezes.
Which of the three traits considered in this film (bipedality, extensive tool use, and large brains) were present in the 3.2-million-year-old Australopithecus fossil (Lucy)?.
Answer:
The bipedality
Explanation:
One of the things the discovered fossil signified was that human bipedality was more ancient than the large brain size because Lucy actually had a small skull which could indirectly be translated to small brain size.
NOTE: Bipedality can be described to mean the ability of an organism to move about with two legs. Hence, it must have been discovered that Lucy had two legs.

and the aqueous solution? Select three options.
Hydrophobic

Hydrophilic
region
Hydrophobic areas move away from water.
O Hydrophilic areas are attracted to water.
Hydrophilic regions of the protein are attracted to
other hydrophilic regions.
Hydrophilic regions of the protein are attracted to

solution
Intro
✓ Done
Answer:
Hydrophobic areas move away from water.
Hydrophilic areas are attracted to water.
Hydrophilic regions of the protein are attracted to other hydrophilic regions.
Explanation:
Proteins are made up of amino acids. The side chains of these amino acids determine whether they are polar or non-polar. Hydrophilic amino acids are the types that are soluble in water and their side chains are polar. They are attracted to protein parts that are water-soluble. Examples are Glutamate and Lysine.
The hydrophobic amino acids have non-polar side chains. They withdraw from water by taking on an oily form. They are attracted to parts of the protein that are not aqueous. Examples are Valine and Tyrosine.
Answer:
1. Hydrophobic areas move away from water.
2. Hydrophilic areas are attracted to water.
5. Hydrophobic and hydrophilic interactions cause protein folding.

7. Chemical or physical factor that determines the number
of organisms in a population
Answer:INTERSPECIFIC COMPETITION
Explanation:
The physical factor that determines the number of organisms in a population is ; Interspecific competition
Interspecific competition in a population is a competition that exists between organisms of different species, while the competition that occurs within organisms of the same specie is termed intraspecific competition.
During Interspecific competition the different species compete for food, water and Habitat which every organism needs to survive, and in most cases the stronger specie overruns the weaker species and this will lead to the depletion in the number of the organisms of the weaker specie and an increase in the number of the stronger specie within the population.
Hence we can conclude that The physical factor that determines the number of organisms in a population is ; Interspecific competition .
