Answers
Answer:
The nitrogen cycle is very important for living organisms and is biologically usable by them. Very essential for the elaboration of DNA, amino acids, proteins and nucleic acids and fundamental for the development or productivity of agriculture.
Explanation:
QUESTION 1 Exercise 11.10. Butterflies. Alice, Bob, and Charlotte are looking for butterflies. They look in three separate parts of a field, so that their probabilities of success do not affect each other. • Alice finds 1 butterfly with probability 17%, and otherwise does not find one • Bob finds 1 butterfly with probability 25%, and otherwise does not find one • Charlotte finds 1 butterfly with probability 45%, and otherwise does not find one Let X be the number of butterflies that they find altogether. Write X as the sum of three indicator random variables, X1, X2, X3 that indicate whether Alice, Bob, Charlotte (respectively) found a butterfly. Then X= X1+X2 +X3. Find the expected value of X by finding the expected value of the sum of the indicator random variables. Your answer will have two decimal places. **This is a straight forward expected value of a sum of random variables, nothing fancy here! QUESTION 2 Exercise 11.16. Flipping coins. Flip a coin until the second head comes up. Let X be the number of flips needed to get the second head. What is the E(X). The first step is to find the expected value of getting the first head. Is this like Example 11.10, sampling without replacement, OR like Example 11.11, sampling with replacement? O A. Example 11.10, sampling without replacement O B. Example 11.11, sampling with replacement QUESTION 3 Exercise 11.16. Flipping coins. Flip a coin until the second head comes up. Let X be the number of flips needed to get the second head. What is the E(X). The first step is to find the expected value of getting the first head. What is the expected value of getting the first head? This will be an integer answer. QUESTION 4 Exercise 11.16. Flipping coins. Flip a coin until the second head comes up. Let X be the number of flips needed to get the second head. What is the E(X). The next step is to find the expected value of getting the second head. Because this is identical to finding the expected number of rolls for the first head (independent events), we just multiply the first head's expected value by 2. This will be an integer answer. QUESTION 5 Exercise 11.17 (a). Waiting for favorite song. Michael puts his iTunes on shuffle mode where songs are not allowed to be replayed. He has 2,781 songs saved on iTunes, and exactly one of these is his favorite. How many songs is he expected to have to listen to until his very favorite song comes up? Is this like Example 11.10, sampling without replacement, OR like Example 11.11, sampling with replacement? A. Example 11.11, sampling with replacement B. Example 11.10, sampling without replacement
Answers
In Exercise 11.10, the expected value of the number of butterflies found by Alice, Bob, and Charlotte is obtained by finding the expected value of the sum of three indicator random variables.
In Exercise 11.16, the expected value of the number of flips needed to get the second head in a coin flipping experiment is determined. These exercises involve different scenarios of sampling with and without replacement.
In Exercise 11.10, the expected value of X, the total number of butterflies found, is found by calculating the expected value of each indicator random variable (X1, X2, X3) representing whether Alice, Bob, and Charlotte found a butterfly, respectively.
The expected value of each indicator variable can be obtained by multiplying the probability of success (finding a butterfly) by 1 and the probability of failure (not finding a butterfly) by 0. Then, the expected value of X is calculated as the sum of the expected values of the indicator variables.
In Exercise 11.16, the expected value of X, the number of flips needed to get the second head, is determined. To find this value, we first need to find the expected value of getting the first head. This scenario is similar to Example 11.11, which involves sampling with replacement.
Each coin flip is an independent event, and the probability of getting a head is constant at 0.5.
Therefore, the expected value of getting the first head is 1/p, where p is the probability of success (0.5 in this case).
In Exercise 11.17 (a), the scenario of waiting for a favorite song in Michael's iTunes playlist involves sampling without replacement. Each song played is not replayed, and there is only one favorite song among the total number of songs.
Therefore, this scenario is similar to Example 11.10, sampling without replacement.
To find the expected number of songs Michael needs to listen to until his favorite song comes up, the formula for sampling without replacement is used, which is the reciprocal of the probability of selecting the favorite song at each step.

Identify the experimental conditions used by clausen to test for genetic differences among populations
Answers
Clausen used clones of populations from different elevations to test for genetic differences among populations.
Clausen employed clones of populations from different elevations as the experimental condition to investigate genetic differences among populations. Clones refer to individuals that are genetically identical to each other, meaning they are derived from a single source. In this case, the clones were obtained from populations residing at different elevations.
By using clones, Clausen ensured that any observed differences were solely due to genetic factors and not influenced by environmental variations. These clones were then subjected to a common garden experiment, where they were grown in different elevations. This experimental design allowed Clausen to assess how genetic traits expressed in different environments, providing insights into the genetic variations among populations from varying elevations.

A student examined two slides in the laboratory, one slide with normally dividing cells and another slide with cancerous cells. Which statement best predicts what the student will observe on the slide with cancer cells compared to the slide with normally dividing cells?
aThe slide with cancer cells will show more cells in interphase because they are growing in preparation for cell division.
b.The slide with cancer cells will show more cells in interphase because the stages of mitosis take longer to complete.
c.The slide with cancer cells will show fewer cells in interphase because the cells are dividing rapidly.
d.The slide with cancer cells will show fewer cells in interphase because the cells are not dividing.
Answers
The answer is option a, The slide with cancer cells will show more cells in interphase because they are growing in preparation for cell division. The correct answer is A.
The slide with cancer cells will show more cells in interphase because they are growing in preparation for cell division. There are some differences between cancer cells and normal cells.
Normally dividing cells go through the cell cycle: G1, S, G2, and M. During G1, cells grow and develop, but they don't begin DNA synthesis. DNA synthesis occurs during S phase, which is followed by G2, where the cell checks and prepares its newly synthesized DNA for mitosis.
Finally, mitosis, which is a sequence of steps during which a cell divides into two identical cells. Cancer cells, on the other hand, do not enter into the G0 phase; instead, they continue to divide.
As a result, they divide more quickly and require more nutrients. Since more cells need to be produced, more cells will be in interphase, growing and developing in preparation for cell division. Therefore, the correct answer is A.

The hiv virus attacks only a certain type of white blood cells, and not other cell types. Why?.
Answers
The HIV virus specifically targets a type of white blood cell called a CD4+ T cell, which is important for the body's immune system.
What is HIV virus?
HIV (human immunodeficiency virus) is a virus that attacks our immune system, the body’s natural defense against illness. HIV is a sexually transmitted infection (STI) and it can also be spread through contact with infected blood or from mother to child during pregnancy, childbirth, or breastfeeding. HIV weakens a person’s ability to fight infections and diseases, and without treatment, it can eventually lead to AIDS (acquired immunodeficiency syndrome).
HIV works by binding to proteins on the surface of these cells, known as CD4 and CCR5, that act as receptors for the virus. This allows the virus to enter inside the cell and infect it. Once inside, it uses the cell's machinery to replicate and spread throughout the body. By specifically targeting these specific types of white blood cells, HIV is able to spread more efficiently and cause more damage to the body's immune system.

The major category(ies) of hypersensitivity that typically involve a B-cell immunoglobulin response is (are) ________.
Answers
The major category of hypersensitivity that typically involves a B-cell immunoglobulin response is Type II and Type III hypersensitivity reactions.
B-cells create antibodies against target antigens found on the surface of cells or in the extracellular matrix in Type II hypersensitivity, which causes cellular or tissue damage. A few types of drug-induced hemolytic anemia and autoimmune hemolytic anemia are examples of Type II hypersensitivity.
In type III hypersensitivity, B-cells create antibodies that interact with soluble antigens to create immunological complexes. These immune complexes may build up in tissues and lead to tissue inflammation and damage. Examples of Type III hypersensitivity include various forms of glomerulonephritis and systemic lupus erythematosus.
It is important to note that B-cell immunoglobulin responses are not present in other forms of hypersensitivity reactions, such as Type I (immediate) and Type IV (delayed).

Answers
The scenario that provides the best chances that an animal will be fossilized is animal is killed and covered in lava from a volcanic eruption.
The correct option is D.
In general , organic material in the animal's body is replaced by minerals from the surrounding sediment, resulting in a fossil. Volcanic eruptions can also create conditions that favor fossil preservation, such as rapid burial, high temperatures, and a lack of oxygen, which can prevent decay and help preserve the animal's remains.
Animal is killed and covered in volcanic lava, it is quickly buried in sediment and protected from scavengers and decomposition. Rapid and complete burial provided by volcanic lava is generally considered the most effective means of preserving animal remains as fossils.
