Many different types of mutations can occur within the body. Sickle cell anemia is a disease that occurs when a mutation in a base pair of the hemoglobin beta gene causes a single replacement of the amino acid glutamic acid by the amino acid valine. As a result of this mutation, the individual’s blood cells take on a sickle shape under certain conditions and form clusters that can block blood vessels and cause organ damage. Which type of mutation causes sickle cell anemia? A)silent B)missense C)insertion D)frameshift


The right option is; B)missense

Missense mutation is the type of mutation that causes sickle cell anemia

A missense mutation is a type of nonsynonymous substitution in which the change of a single nucleotide (base pair) influences the genetic code and results in a codon that code for a different amino acid. This type of mutation can affect the function of the protein, and it is responsible for human diseases such as, sickle-cell anemia and Epidermolysis bullosa.

How many milliliters of sodium metal, with a density of 0.97 g/mL, would be needed to produce 34.5 grams of sodium hydroxide in the single replacement reaction below? Unbalanced equation: Na + H2O —> NaOH + H2


The balanced chemical reaction is as shown below,

                 N₂ + 3H₂  –> 2NH₃

The equation shows that every 3 moles of hydrogen, H2, there would be 2 moles of ammonia, NH3, that is going to be formed. Using this concept, we solve for the unknown in this item. 

Since we are restricted only of the number of hydrogen, it becomes our limiting reactant. 

          (6 moles H2) x (2 moles NH3/3 moles H2) = 4 moles NH3

Therefore, given enough amount of N2, the amount of NH3 that can be formed out of the 6 moles of H2 is equal to 4 moles.

You need to determine the number of ways in which 30 competitors from 50 can qualify. First, you have to realize that the order is irrelevant, that is: it is the same competitor_1, competitor _2, competitor _3 than competitor_3, competitor_2, competitor_1, or any combination of those three competitors.

So, the number of ways is which 30 competitors from 50 can qualify is given by the formula of combinations, which is:

C (m,n) = m! / (n! * (m -n)! )

=> C (50,30) = 50! / (30! (50 – 30)! ) = (50!) / [30! (50 – 30)!] = 50! / [30! 20!] =

 = 47,129,212,243,960 different ways the qualifiying round of 30 competitors can be selected from the 50 competitors.

You are dealt two cards successively (without replacement) from a shuffled deck of 52 playing cards. find the probability that the first card is a king and the second card is a queen.


Answer:

(C)0.20

Step-by-step explanation:

We are given that we have to make five-letter codes that use the letters A, F, E, R, and M without repeating any letter.

Thus, total number of letters=5

Now, the probability that a randomly chosen code starts with A is given as:

P=frac{Favourable outcomes}{Total number of outcomes}

P=frac{1}{5}

P=0.20

Therefore, the the probability that a randomly chosen code starts with A is 0.20.

Hence, option C is correct.

What vitamin is involved heavily with the replacement of red blood cells and digestive tract cells?


The right answer is Transgenic organisms can produce a desired product that may benefit other organisms.

A transgenic organism contains DNA combining  stably integrated in all its cells. In other words, the organism, be it a plant, an animal or a microorganism, has a new piece of DNA embedded in it. a chromosome in each of its cells. This “new piece” of DNA usually contains a gene from another organism (plant, animal or other) that has been modified to be expressed in the new  organization. A transgenic organism may even possess the DNA of another organism of the same species. The inserted gene can be called the transgene.

Currently, diabetics are treated by injecting insulin from either a healthy human donor or cultures of genetically modified (transgenic) bacteria that secrete the protein.

Which clue can be used to identify a chemical reaction as a replacement reaction? The reaction has two reactants with ions that seem to switch places. The reaction has a single reactant that changes into two or more products. The reaction involves oxygen reacting with a hydrocarbon and giving off heat. The reaction involves a single product forming from two or more reactants.


Answer: Option (a) is the correct answer.

Explanation:

A replacement reaction is a chemical reaction in which a more reactive atom or ion displaces least reaction atom or ion.

For example, NaCl + H_{2}O rightarrow NaOH + HCl

Here, Na gets replaced by H atom and Cl ion gets replaced by OH ion.

Whereas when teo or more reactants combine to forms a single product then that reaction is a synthesis reaction and not a displacement reaction because two different ions or atoms combine together to form a single product.

For example, Na^{+} + Cl^{-} rightarrow NaCl is a synthesis reaction.

Thus, we can conclude that the reaction has two reactants with ions that seem to switch places is a clue that can be used to identify a chemical reaction as a replacement reaction.

Answer: Option (b) is the correct answer.

Explanation:

It is known that general charge on a hydrogen atom is +1, oxygen atom is -2, and sodium atom is +1.

Hence, oxidation number of nitrogen atom in the given species or compounds is as follows.

  • NH^{+}_{4}

                     x + 4(1) = 1

                         x = 1 – 4

                            = -3

  • N_{2}O_{5}

                       2x + 5(-2) = 0         (since total charge on the molecule is zero)

                          x = +5

  • NaNO_{3}

                      1 + x + 3(-2) = 0

                            x = +5

Thus, we can conclude that the oxidation numbers of nitrogen in NH4+, N2O5, and NaNO3 are -3, +5, +5 respectively.

Read the passage. Then, answer the question(s). A modern dentist would certainly enjoy having a hadrosaur as a client. Although an adult human being has only 32 teeth, these duck-billed dinosaurs of the Late Cretaceous Period had up to 2,000 teeth, with 500 along each side of each jaw. Unlike human beings, who grow two sets of teeth in their lifetimes, the hadrosaurs, like sharks and modern reptiles, had built-in replacement teeth. If a tooth became worn down or broke off, a new one would take its place. In skeletal remains of the jaws of these toothy beasts, scientists have found entire banks of replacement teeth. Like athletes sitting on the bench, they were ready and waiting to be put to use. Which statement or detail from the passage best helps readers picture a hadrosaur’s teeth?


The correct answer is A. A tragedy has characters who suffer pain and loss, while a comedy has funny situations and a happy ending.

Explanation;

Both tragedy and comedy are genres of literature that commonly display fictional stories, character, and events; however, they differ in their focus and features. In the case of tragedy, this has a sad ending and the situations presented include mostly events that focus on suffering and difficult situations the characters are unable to overcome.

On the other hand, the comedy focuses on humor and entertaining situations, has a happy ending and aims at entertaining and making the audience laugh rather than making them feel bad about characters. According to this, the statement that shows the difference between tragedy and comedy is “A tragedy has characters who suffer pain and loss, while a comedy has funny situations and a happy ending”.
