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
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.

Explain how ATP and creatine phosphate function in skeletal muscle fiber contraction.
In a muscle at rest, extra ATP converts creatine into ADP and creatine phosphate by transferring its energy. This serves as a source of energy that may be swiftly drawn upon to produce further ATP.
Creatine phosphate transfers its phosphate back to ADP to form ATP and creatine when the muscle begins to contract and needs energy.
ATP provides the necessary energy for muscular contraction. The active-transport Ca++ pumps in the SR are powered by ATP, which also plays a direct role in the cross-bridge cycle. Without enough ATP, muscle contraction is impossible. Only a few seconds' worth of muscular contractions can be powered by the tiny quantity of ATP that is stored in muscle. To enable persistent contraction, ATP must be rapidly created and supplied as it is depleted. Three processes—creatine phosphate metabolism, anaerobic glycolysis, fermentation, and aerobic respiration—can regenerate ATP.

what effect do you think deficiencies in lysosomal enzymes would have on phagocytes? what effect do you think deficiencies in lysosomal enzymes would have on phagocytes? there would be decreased levels of endocytosis occurring. phagocytes would lose the capability to digest bacteria. materials composed of cells will not be able to be packaged and modified. production of atp will decrease.
Deficiencies in lysosomal enzymes would have significant effects on phagocytes, including decreased levels of endocytosis, loss of the capability to digest bacteria, inability to package and modify materials composed of cells, and a decrease in ATP production.
(a) Lysosomal enzymes are crucial components of the lysosomes, which are responsible for the degradation and recycling of various cellular components, including foreign substances and pathogens, within phagocytes.
(b) Phagocytes are a type of immune cells, such as macrophages and neutrophils, that play a key role in engulfing and eliminating pathogens, such as bacteria, through a process called phagocytosis.
(c) Deficiencies in lysosomal enzymes would impair the phagocytes' ability to carry out their essential functions. Here's how:
Decreased levels of endocytosis: Lysosomal enzymes are involved in the endocytosis process, where phagocytes internalize particles or pathogens by engulfing them. Deficiencies in lysosomal enzymes would lead to a decrease in the efficiency of endocytosis, limiting the phagocytes' ability to capture pathogens.Loss of capability to digest bacteria: Lysosomal enzymes are responsible for breaking down the engulfed bacteria or foreign particles inside the phagocytes. Without sufficient lysosomal enzymes, the phagocytes would lose their ability to digest and degrade bacteria, compromising their ability to eliminate pathogens effectively.Inability to package and modify cellular materials: Lysosomal enzymes are involved in the packaging and modification of cellular materials within phagocytes. Deficiencies in these enzymes would disrupt the proper processing and packaging of cellular components, affecting the phagocytes' overall function.Decreased ATP production: Lysosomal enzymes are also involved in the intracellular energy metabolism and ATP production. Deficiencies in lysosomal enzymes could disrupt this process, leading to a decrease in ATP production within the phagocytes. This reduction in energy availability could impair various cellular functions, including phagocytosis and pathogen elimination.For more such questions on lysosomal enzymes, click on:

Which phylum to not have an internal or external skeleton or shell?
Answer:
exoskeleton (from Greek έξω, éxō "outer" and σκελετός, skeletós "skeleton"[1]) is the external skeleton that supports and protects an animal's body, in contrast to the internal skeleton (endoskeleton) of, for example, a human. In usage, some of the larger kinds of exoskeletons are known as "shells". Examples of animals with exoskeletons include insects such as grasshoppers and cockroaches, and crustaceans such as crabs and lobsters, as well as the shells of certain sponges and the various groups of shelled molluscs, including those of snails, clams, tusk shells, chitons and nautilus. Some animals, such as the tortoise and turtle (shell page), have both an endoskeleton and an exoskeleton.

FILL IN THE BLANK. viruses are often isolated from cells by filtration based upon the fact that they ______.
Viruses are often isolated from cells by filtration based upon the fact that they are smaller than the pore size of the filter.
Virus, a small, basic infectious agent that can reproduce only in live cells of animals, plants, or microorganisms. The term is derived from a Latin word that means "slimy liquid" or "poison." Dmitry I, a Russian scientist, conducted the first study on the biological nature of viruses in 1892.
A virus is a submicroscopic infectious agent that multiplies solely within an organism's live cells. Viruses infect all kinds of life, including animals and plants, as well as microbes such as bacteria and archaea. They proliferate at an astonishing pace, but only in living host cells. They are acellular, which means they lack cytoplasm and cellular organelles. They have no metabolic mechanism of their own and must multiply utilising the metabolic machinery of the host cell.

State one similarity and one difference between parasitic and predatory modes of feeding
Answer:
One similarity between parasitic and predatory modes of feeding is that both involve the ingestion of other organisms for nutrition. In both cases, the organisms that do the feeding (the parasites or predators) obtain their food from other organisms (the host or prey), which they consume and use to nourish themselves.
One difference between parasitic and predatory modes of feeding is the relationship between the predator and its prey. In predatory feeding, the predator and its prey are typically separate and distinct organisms, and the predator actively hunts and kills its prey for food. In parasitic feeding, the parasite and its host are typically closely associated, and the parasite typically lives on or inside the host, feeding off of its nutrients or tissues. This relationship between the parasite and its host is often harmful to the host, while the relationship between the predator and its prey is typically not harmful (as long as the predator is not over-consuming its prey).
