Answer:
pseudoscience
Explanation:
In nature, some ideas, beliefs or knowledge are mistaken to be scientific but in actual sense they are not supported by evidence using scientific method. These sorts of ideas are called PSEUDOSCIENCE. They do not follow the scientific method principles, hence, cannot be tested scientifically.
Pseudoscience is termed "fake science" as the name implies because they are brought forth as science in order to justify their claim but they are not in consistency with the scientific method. They lack the ability to be tested as false via experimentation. An example of pseudoscience as stated in the question is Bigfoot
A collection of ideas and beliefs that sound like science but are not supported by evidence, such as bigfoot, is known as - pseudoscience
Pseudoscience
These are the ideas or beliefs that appear to be the same as science are actually come with confirmation but are not supported by evidence whereas science is ideas that are based on pure evidence that can be challenged.
Pseudoscience is based on claims whereas science is based on facts and evidence. Theory, laws, and fact are part of science as these seek falsifications.

Answer: a volcano erupts, a river deposits gravel at a bend , plate movement creates mountains
Explanation:
A statement describe constructive forces is a volcano erupts, a river deposits gravel at a bend , plate movement creates mountains.
What is constructive force?Constructive force is defined as a method of raising or constructing the Earth's surface features. The planet undergoes constructive processes when events take place that improve or transform it. The procedure by which sand is dumped upon a river bank by the flowing water is an illustration of a constructive process. The river bank is raised as a result of this construction.
Mountains and land are formed throughout time by volcanic activity. inside a volcano, heated, molten rock. On the surface of the Earth, lava flows from the volcano. Igneous rock is created as it cools. The deformation of the crust, volcanic eruptions, and sediment deposition are three of the primary constructive factors. Crustal deformation is the alteration or deformation of the shape of the land. The shifting of the Earth's plates is one of the key causes.

How useful is the cell type in classifying organisms?
Answer:
without cell type u cannot classifiy organisms
The cell type is extremely useful in the classification of organisms. This is because the cell type distinguishes the structural morphology and functional property of an organism with respect to its phenotypical features.
What is Cell type?Cell type may be defined as a group of cells that possess a common transcriptomic signature and low variation in other phenotypes. Cell types are utilized in order to identify cells on the basis of their morphological or phenotypical features.
It is only the cell types that enable people to understand and estimate how a complex organism evolved from a simpler organism. It also allows us to understand and study on the basis of their features, similarities, dissimilarities, etc. among diverse organisms.
Cell types also provide us with a brief evolutionary history of the organisms and the other organisms that are closely associated with them.
Therefore, the cell type is extremely useful in the classification of organisms.

Calculate the pI of Histidine (pKa’s = 2.3, 6.04, 9.33)
6.11
7.68
3.08
2.35
4.07
Answer:
The correct answer is 7.68
Explanation:
Isoelectric point (pI) is the pH at which the amino acid has net a charge of zero. We have to choose the two values of pKa at which the neutral form of the amino acid is predominant. Histidine (Hys) is a basic amino acid. From pKa's data, we deduce:
pKa1 = 2.3 (corresponds to α- carboxyl group)
pKa2= 6.04 (corresponds to R group)
pKa3= 9.33 (corresponds to α- amino group)
Since it is a basic amino acid, the neutral form will exist between the higher pKa's values. Thus, the pI will be in a pH value between 6.3 and 9.33.
So, we have to calculate the average of pKa2 and pKa3:
pI= (pKa2+pKa3)/2= (6.04+9.33)/2= 7.68
Therefore, the pI of Hys is 7.68.

Look at the numbers used on the vertical axis. What
would happen to the bars on the graph if these numbers
were changed to 100, 150, 200, and 300?
Answer and Explanation: You will find the graph in the attached file
When changing the numbers in the vertical axis of the original graph, you will see that bars tend to get shorter than they originally were. This occurs because new numbers are much bigger than the original numbers, the proportion of the bars changes because they must represent the same information in a much bigger space. Offenlly, this is a tool very used by media to mark a tendency when informing something. So It is very important whenever looking at any graph to see what the axes are telling you because by the size of the bars you might infer something that might be different from what is really going on.
Streptomycin is an effective antibiotic because _____________.
a) it inhibits protein synthesis in prokaryotes
b) it does not affect eukaryotes
c) both
d) neither
Answer: Option C.
Both
Explanation:
Streptomycin is an antibiotics produced from bacteria and fungi and it is used to treat bacteria infections (prokaryotic ) such as tuberculosis, mycobacterium infection e.t.c.
It's inhibit protein function in prokaryotes because it's affects the function and performance of 70 s RIBOSOMES which is an organelles for protein production.
Streptomycin does not affect eukaryotes because it does not bind to the RIBOSOMES of eukaryotic cells which in turn does not affect protein production.
How would you describe a bottle that contains 0.95 moles of hydrogen peroxide per liter of solution?
Answer:
A bottle that contains 0.95 moles of hydrogen peroxide per liter of solution contains 32.31 g of hydrogen peroxide per liter of the solution.
Explanation:
First, recall that:
Molarity of a substance = no of moles of the substance/volume of the solution in liters.
In this case, the number of moles of hydrogen peroxide is 0.95 mole while the volume of the solution is one liter. Thus;
Molarity of hydrogen peroxide = 0.95/1 = 0.95 M.
Also recall that:
no of moles of a substance = mass of the substance/molar mass of the substance.
Thus;
mass of substance = no of moles x molar mass.
In this case, the no of moles of hydrogen peroxide is 0.95 while the molar mass is 34.01 g/mol. Hence;
mass of hydrogen peroxide = 0.95 x 34.01 = 32.31 g
Hence, a bottle that contains 0.95 moles of hydrogen peroxide per liter of solution contains 32.31 g of hydrogen peroxide per liter of the solution. The solution also has a hydrogen peroxide molarity of 0.95 M.
The amount of hydrogen peroxide in the solution can be expressed in grams per Litre as 32.31 gram of hydrogen peroxide per Litre of the solution.
The amount of mole of hydrogen peroxide in the solution = 0.95 moles
The Molar mass of hydrogen peroxide = 34.0147 g/mol
The mass of hydrogen in the solution can be calculated thus :
Number of moles of hydrogen peroxide × Molar mass of hydrogen peroxide Mass of hydrogen = 0.95 mol × 34.0147 g/mol = 32.314 gTherefore, the bottle contains 31.314 g of hydrogen peroxide per Litre of the solution.
