The statement "motor or efferent neurons carry signals to a muscle or gland called the effector" is true.
Motor neurons (also called efferent neurons) receive signals from the central nervous system (CNS). These signals are transmitted through the motor neurons to reach their target. The target of motor neurons is either a muscle or a gland. The muscle or gland receiving the signal is called the effector. The effector then responds to the signal by either contracting (in the case of a muscle) or secreting substances (in the case of a gland).

colorblindness is an x-linked recessive genetic trait. the frequency of the mutant colorblind allele is 1/50. what is the probability that k will be colorblind if he is male? it is not known if anyone in the family is colorblind
The probability of K being colorblind if he is male is equal to the probability of the mother carrying the mutant colorblind allele, which is 1/50.
Colorblindness is an X-linked recessive genetic trait, meaning it is associated with genes located on the X chromosome. In males, who have one X chromosome, the presence of the colorblind allele on that chromosome determines whether they will be colorblind or not.
The given information states that the frequency of the mutant colorblind allele in the population is 1/50, which means that in a random individual, there is a 1/50 chance of having the colorblind allele.
Since it is not known if anyone in K's family is colorblind, we assume that the mother's allele frequency is the same as the general population. Therefore, the probability of the mother carrying the mutant colorblind allele is also 1/50.
As K is male, he inherits his X chromosome from his mother. If his mother carries the mutant colorblind allele and passes it on to him, he will be colorblind. Thus, the probability of K being colorblind if he is male is equal to the probability of the mother carrying the mutant colorblind allele, which is 1/50.

¿Podrá la planta producir frutos dentro de una caja oscura?
Answer:
No.
Explicación:
No, la planta no podrá dar fruto en una caja oscura porque para su crecimiento la planta necesita luz solar y sin luz solar no se produce fotosíntesis y sabemos que en el proceso de fotosíntesis, las plantas preparan su propia comida y crecen en tamaño. Este proceso de fotosíntesis solo ocurre en presencia de luz solar, por lo que en la oscuridad no hay luz solar, por lo que no se produce la fotosíntesis y la planta morirá.

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.

According to the poiselle's low , if the radius of the
blood vessels decreases by 2; what happens to the resistance of
that blood vessel
According to Poiseuille's law, if the radius of a blood vessel decreases by 2, the resistance of that blood vessel will increase.
Poiseuille's law describes the relationship between the radius of a blood vessel, the flow rate of blood through the vessel, and the resistance to that flow. According to the law, the resistance (R) of a blood vessel is inversely proportional to the fourth power of its radius (r). In mathematical terms, the formula is R ∝ 1/r^4.
When the radius of a blood vessel decreases by 2, it means that the new radius is half of the original radius. If we substitute this new radius into the Poiseuille's law equation, we find that the resistance will increase significantly. Since the resistance is inversely proportional to the fourth power of the radius, decreasing the radius by 2 will result in an increase of (1/0.5)^4 = 2^4 = 16 times in resistance.
In simpler terms, if the radius of a blood vessel decreases, the available space for blood to flow through becomes smaller. This reduction in space leads to increased friction between the blood and the vessel walls, which in turn increases the resistance to blood flow. Consequently, the heart has to work harder to pump the blood through the constricted blood vessels, leading to increased pressure within the vessels.
In summary, according to Poiseuille's law, when the radius of a blood vessel decreases by 2, the resistance to blood flow through that vessel increases significantly. This highlights the importance of maintaining healthy blood vessel function and avoiding conditions that can cause constriction or narrowing of the vessels.

a. The DNA is the same for all the victims
b. People's pets were found with them
c. Collapse of the walls from the big earthquake
d. Lahar deposits that cover the site
e. most bodies are found in a single surge layer
Most bodies are found in a single surge layer. Therefore, option (E) is correct.
The majority of the bodies were found in a single surge layer, which is the main indicator of the timing of the most fatal incident. This implies that a catastrophic occurrence, like a natural disaster or a mass casualty event, took place at a certain period and caused the remains to be deposited in a concentrated layer.
This data suggests that a single incident, as opposed to several events spread out across time, was responsible for the high fatality rate. The presence of a distinct surge layer can offer important clues about the kind and timing of the incident that caused the fatalities.

prehensile tails are: group of answer choices present in catarrhine primates. made strictly of muscle. present only in some platyrrhines. present in most primates.
Prehensile tails are a group of answer choices present in some platyrrhine primates, which are made strictly of muscle and used for grasping branches.
Prehensile tails are a unique feature of some New World monkeys, or platyrrhines, and are not present in catarrhine primates, such as apes and Old World monkeys. These tails are specialized appendages that are made up of a combination of skin, bone, and muscle, with the muscle being the most important component. The muscles in the tail are arranged in a way that allows the tail to wrap around branches and grasp them tightly, providing a fifth limb for these primates.
Platyrrhine primates that possess prehensile tails include species of spider monkeys, howler monkeys, and capuchin monkeys. These primates are arboreal, meaning they live in trees, and use their prehensile tails to move through the forest canopy with ease. In addition to their use for locomotion, prehensile tails are also important for gathering food, as they allow these primates to reach and grasp fruits and leaves that might be otherwise out of reach. Overall, prehensile tails are an incredible adaptation that has allowed some primates to thrive in their arboreal habitats.
