Answer:

The answer is scientific method.

Explanation:

The Scientific Method:

The Scientific Method is the standard process of experimentation and inquiry used to test hypothesis and answer scientific questions.

Every scientific question requires a specific form of the scientific method, with the variations ranging from the scope of the hypothesis to the experimental design and data analysis methods.

The steps of the scientific method are as follows:

1. Observation/Question

2. Hypothesis

3. Experimentation

4. Data analysis

5. Conclusion

The conclusion includes analysing the results and developing further hypotheses and testing them. If the hypothesis remains irrefutable, it becomes a theory. If the theory remains irrefutable after rigorous experimentation in various studies by multiple scientists, the theory becomes a law.

Dengue fever is an infectious disease of humans that is caused by a virus. There are four main viral strains, and an individual
Yuri [45]

Answer:

12

Explanation:

Suppose the four different strains are P, Q, R, S. Thus, the first infection can be from any of the four strains and it occurs in 4 ways.

Since an individual cannot be infected again with the strain from which he/she is been previously infected;

Then, at the second time;

The possible number of strain to be infected with = 4-1 = 3 ways

Thus; the number of possible different levels of severity can be viewed by forming two lettered word  P, Q, R, and S without repetition which is:

= 4 × 3

 = 12

Which statement is true about extracted lipid?
SSSSS [86.1K]

Answer:

The right answer is (B) the extracted lipids cover twice the surface area of the intact red blood cells.

Explanation:

To explain this statement is necessary to take into consideration the structure of a lipid. On the first place lipids that form membranes are called phospholipids, this means they have one 'head' that is hydrophilic and a tail composed by the lipidic chain that is hydrophobic.

In a biologic context, the phospholipids form the cellular membrane. They do so by a bi-layer disposition, meaning that one the external side of the cell there is a layer of phospholipids with the hydrophilic head and in the internal side, there is a second layer of phospholipids with the hydrophilic head. The hydrophobic 'tails' are in the middle. This disposition is due to the fact that both the external and the internal environments are water based.

Therefore, since each cell has a bilayer membrane of phospholipids, when the cells are dissolved and all the lipids that used to form the membrane are put together, they will occupy twice the surface of the red blood cells.
