What is a rectangular prism?
A rectangular prism is a geometrical figure. It is basically a polyhedron and has two congruent and parallel bases. It is also known as a cuboid.
A rectangular prism is made of six faces and each of the faces has twelve edges. It is called a prism because it has cross-sections along the length.
A rectangular prism is a three-dimensional figure with six faces. All the faces of the prism are rectangular in shape. Hence, there are three pairs of identical faces here. A rectangular prism is also called a cuboid due to its shape.
The rectangular prism has 6 faces, 12 edges and 8 vertices.
The top portion and the base portion of the rectangular prism are always a rectangle. It has three dimensions like a cuboid. These are length, width and height. The opposite faces of the prism are always congruent.
Therefore, the parallel lines to BD are PY, MK and AH. So the correct options are A, D and E.

why does mercury have such a dramatic different temperatures during the day and night
Answer:
Mercury rotates slowly and has a thin atmosphere, and consequently, the night-side temperature can be more than 1,000 degrees Fahrenheit lower than the day-side temperature shown on the diagram. It can be as cold as -290 degrees Fahrenheit (-179 degrees Celsius) on Mercury at night.
Explanation:
Answer:
due to its rotation and lack of atmosphere
Explanation:
during the day the temperature is so high that it could melt some metals and during the night the temperature drops well below freezing.

Al is analyzing the musculature involved in the athletes he coaches. Today he is observing a basketball player executing a jump shot. Which muscles are involved at the hips, knees, and ankles as the athlete jumps? which muscles are involved at the shoulders, elbows, and wrists as the athlete shoots the basketball?
Muscles of the hips and ankles are involved at the hips, knees, and ankles as the athlete jumps. The muscles of the arm, forearm, and hand are involved as the athlete shoots the basketball.
When landing from a jump, the muscles of the hips (gluteals), knees (quadriceps and hamstrings), and ankles (calves) that increase jump height are just as important. The flexors of the arm (anterior deltoid, biceps, coracobrachialis), forearm (brachialis), and hand during the handling phase, as well as the extensors (triceps) and pronators (pronator teres) of the forearm during the finishing stage of the shot, are the primary muscle groups of the upper limb that intervene during the action of the shooting. Until the player does not bend, the lower limb muscles contract isometrically and work concentrically (knee flexors) during the bending step.

what's the factor that determines the type of vision of animals ??
In a rain forest, it is well known that 61% of water lizards have webbed-feet which provide the ability to walk on water. Furthermore, the gene for possessing webbed-feet is not hereditary and, thus, each water lizard is independent of others. A biologist randomly selects 25 water lizards from the rain forest. Let the random variable X count the number of water lizards out of the 25 who have webbed-feet. (a) State the distribution of the random variable defined above. (b) Compute the probability that exactly 17 of the 25 selected water lizards have webbed-feet. (c) Compute the probability that at least 17 of the 25 selected water lizards have webbed-feet. (d) Compute the mean and standard deviation for the number of water lizards out of 25 who have webbedfeet. Use both to describe the typical number of water lizards out of 25 who have webbed-feet. Report 6. Suppose the number of patients per week that visit a health center follows a Poisson distribution with a rate of 300 patients per week. Let the random variable X count the number of patients that visit the health center during a randomly selected week. (a) State the distribution of the random variable defined above. (b) Compute the probability that exactly 310 patients visit the health center during a randomly selected week. (c) Compute the probability that more than 280 patients visit the health center during a randomly selected week.
The distributions of the random variables in the given scenarios are (a) binomial for the water lizards and (b) Poisson for the health center visits. The probabilities can be calculated using the respective formulas for the corresponding distributions.
(a) The distribution of the random variable X, which counts the number of water lizards out of the 25 selected with webbed feet, follows a binomial distribution.
This is because each lizard can be considered as a Bernoulli trial (success: possessing webbed feet, failure: not possessing webbed feet) with a probability of success (p) equal to 61% or 0.61, and the trials are independent.
(b) To compute the probability that exactly 17 of the 25 selected water lizards have webbed feet, we can use the binomial probability formula.
The probability mass function (PMF) for the binomial distribution is given by P(X = k) = C(n, k) * p^k * (1-p)^(n-k), where C(n, k) represents the number of combinations of n items taken k at a time. Plugging in the values, we have P(X = 17) = C(25, 17) * 0.61^17 * (1-0.61)^(25-17).
(c) To compute the probability that at least 17 of the 25 selected water lizards have webbed feet, we need to calculate the cumulative probability from 17 to 25. This can be done by summing up the probabilities for each value of X from 17 to 25: P(X ≥ 17) = P(X = 17) + P(X = 18) + ... + P(X = 25).
(d) The mean (μ) and standard deviation (σ) for the number of water lizards out of 25 who have webbed feet can be calculated using the formulas for the binomial distribution.
The mean is given by μ = n * p, where n is the number of trials (25) and p is the probability of success (0.61). The standard deviation is given by σ = sqrt(n * p * (1-p)).
Moving on to the second scenario:
(a) The distribution of the random variable X, which counts the number of patients that visit the health center during a randomly selected week, follows a Poisson distribution.
This is because the number of patients per week can be modeled as a Poisson process, where events (patient visits) occur independently and at a constant average rate (300 patients per week).
(b) To compute the probability that exactly 310 patients visit the health center during a randomly selected week, we can use the Poisson probability formula.
The probability mass function (PMF) for the Poisson distribution is given by P(X = k) = (e^(-λ) * λ^k) / k!, where λ is the average rate of the Poisson process (300 patients per week) and k is the number of events we are interested in (310 patients).
(c) To compute the probability that more than 280 patients visit the health center during a randomly selected week, we need to calculate the cumulative probability from 280 to infinity. This can be done by summing up the probabilities for each value of X from 280 to infinity: P(X > 280) = P(X = 281) + P(X = 282) + ... + P(X = ∞).

Which of the following statements has not been indicated by research on food and hunger behaviors? ( psychology)
Option D) Children are more likely to eat certain foods after seeing a parent eat them.
Research on food and hunger behaviors has consistently indicated that children are more likely to eat certain foods after seeing a parent eat them. This phenomenon, known as observational learning or social modeling, has been widely documented in various studies. Children tend to imitate their parents' eating behaviors and food choices, and parental eating habits can significantly influence children's food preferences and consumption patterns.
Observational learning is a fundamental aspect of human behavior, particularly during childhood, when children learn and acquire various behaviors and preferences from their immediate environment. Children often look to their parents as role models and are highly influenced by their actions and behaviors, including eating habits. Research has shown that when children observe their parents consuming specific foods, they are more inclined to try and accept those foods themselves, even if they were initially hesitant or resistant.
Therefore, the statement that children are more likely to eat certain foods after seeing a parent eat them has indeed been indicated by research on food and hunger behaviors. Therefore the correct option is D

Answer:23,46 in that order and dominant
Explanation:
for this question, unless they are clearly affected with the disease (like individual ii-5), assume that the disease allele is rare in the population and that people marrying in do not carry the disease allele.
Based on the given condition of the question the disease is sickle cell anemia.
Sickle cell anemia is one of a group of inherited disorders known as sickle cell disease. It affects the shape of red blood cells, which carry oxygen to all parts of the body.
Red blood cells are usually round and flexible, so they move easily through blood vessels. In sickle cell anemia, some red blood cells are shaped like sickles or crescent moons. These sickle cells also become rigid and sticky, which can slow or block blood flow.
Sickle cells break apart easily and die. Red blood cells usually live for about 120 days before they need to be replaced. But sickle cells typically die in 10 to 20 days, leaving a shortage of red blood cells (anemia). Without enough red blood cells, the body can't get enough oxygen, and this causes fatigue.
Periodic episodes of extreme pain, called pain crises, are a major symptom of sickle cell anemia. Pain develops when sickle-shaped red blood cells block blood flow through tiny blood vessels to your chest, abdomen and joints. The pain varies in intensity and can last for a few hours to a few days. Some people have only a few pain crises a year. Others have a dozen or more a year. A severe pain crisis requires a hospital stay.
Some adolescents and adults with sickle cell anemia also have chronic pain, which can result from bone and joint damage, ulcers, and other causes. Swelling of hands and feet. The swelling is caused by sickle-shaped red blood cells blocking blood circulation in the hands and feet.

F- Explain the global carbon-climate cycle during the Cretaceous period. (Write only one paragraph describing what happened during the Cretaceous geological period in order to have good source rocks.)
During the Cretaceous period, high temperatures and abundant vegetation resulted in increased \(CO_2\) levels, leading to the accumulation of organic matter and the formation of good source rocks for oil and gas.
During the Cretaceous period, spanning from approximately 145 to 66 million years ago, the global carbon-climate cycle played a crucial role in the development of favorable conditions for the formation of good source rocks. The period was characterized by high global temperatures and abundant vegetation, resulting in increased carbon dioxide \((CO_2)\) levels in the atmosphere.
The elevated \(CO_2\) levels fueled vigorous photosynthesis, leading to the accumulation of organic matter in marine and terrestrial ecosystems. As this organic matter was buried and subjected to heat and pressure over millions of years, it transformed into oil and gas, creating potential source rocks. The warm climate and prolific vegetation during the Cretaceous, along with the subsequent geological processes, contributed to the formation of the rich hydrocarbon reserves that are vital to our energy resources today.

what did dawson find in his study of selection in tribolium?
Dawson found that the selection process in Tribolium is influenced by the size of the population. In smaller populations, the effects of selection are weaker, while in larger populations, the effects of selection are stronger. This is because in larger populations, there are more individuals with a wider range of genetic variation, which allows for stronger selection pressures. Dawson's study also showed that the effects of selection can be influenced by environmental factors, such as temperature and humidity.
In summary, Dawson's study of selection in Tribolium revealed that the size of the population and environmental factors can both influence the strength of selection pressures. These findings have important implications for understanding the evolutionary processes that shape the genetic makeup of populations.

5. What are virus hoaxes? Why are the hoaxes sometimes more dangerous than an actual virus?
Answer:
An actual computer virus is a malicious software, often known as malware, that can harm a computer and its users.
Virus hoaxes are false or misleading information about viruses that circulate through various communication channels.
They can be more dangerous than actual viruses due to their ability to spread quickly, cause panic, and undermine effective public health measures.
Virus hoaxes are deceptive messages or claims that often exaggerate the severity or impact of a particular virus. They can be spread through social media, email chains, or word of mouth. These hoaxes may include misinformation about symptoms, transmission methods, or false remedies, leading people to take ineffective or even harmful actions.
What makes virus hoaxes particularly dangerous is their potential to create panic and misinformation at a rapid pace. The viral nature of social media and other communication platforms allows these hoaxes to reach a wide audience within a short period. As a result, people may make decisions based on false information, such as avoiding necessary medical treatment, taking unnecessary precautions, or spreading fear and misinformation to others.
Moreover, virus hoaxes can undermine public health efforts by diverting attention and resources from legitimate preventive measures. They can erode trust in healthcare authorities and disrupt the dissemination of accurate information, making it harder for individuals to make informed decisions and follow recommended guidelines.
This can have severe consequences, especially during outbreaks or pandemics, where timely and accurate information is crucial for public safety. Therefore, it is essential to verify the credibility of information and rely on trusted sources to mitigate the risks associated with virus hoaxes.
