The amusement park will be located in a hot climate. The engineers want to select a material for the giant slide that will prevent the surface from getting too hot. Based on the specific heat values, what material would be the best choice? A.Plastic, because it takes more energy to raise its temperature B.Iron, because it takes more energy to raise its temperature C.Plastic, because it takes less energy to raise its temperature D.Iron, because it less energy to raise its temperature
Answer:
A
Explanation:
The correct answer would be plastic because it takes more energy to raise its temperature.
The specific heat capacity of a substance is the amount of heat required to raise the temperature of the substance by one degree. The more the specific heat capacity of a substance, the more the heat required to raise its temperature.
The specific heat capacity of plastics is generally more than that of metals. Hence, metals will get heated faster than plastics under the same condition. More energy would be needed to raise the temperature of plastics when compared to metals.
the correct option is A.
In humans type A blood is caused by the antigen A in the red cells resulting from gene A. Type B is caused by a gene B for antigen B. Type O blood results from the absence of either gene while the presence of both genes causes both antigens to be formed resulting in type AB blood. If a person of blood group AB marries one belonging to blood group O what will be the blood groups of their children? Show the Punnett square for this cross.
Answer:
Type A and type B
Explanation:
This question is describing blood type in humans. According to the question, type A blood is caused by the antigen A of gene A while Type B is caused by a gene B for antigen B. Type O blood results from the absence of either gene while the presence of both genes causes both antigens to be formed resulting in type AB blood.
If a person of blood group AB i.e. genotype (iAiB) marries one belonging to blood group O (genotype ii), the following genotypes of offsprings will be produced (see attached image for punnet square):
iAi - blood type A
IBi - blood type B
What does the term “carbon cycle” mean?
Answer:
Carbon cycle is:
the series of processes by which carbon compounds are interconverted in the environment, involving the incorporation of carbon dioxide into living tissue by photosynthesis and its return to the atmosphere through respiration, the decay of dead organisms, and the burning of fossil fuels.

A) THE CAR AT THE BOTTOM OF THE HILL
B) THE CAR IN THE MIDDLE OF THE HILL
C) THE CAR AT THE TOP OF THE HILL
D) ALL OF THE CARS HAVE ZERO POTENTIAL ENERGY
Answer:the car at the top of the hill
Explanation: it has the most potential energy. If it is sitting still, it has no kinetic energy. As the car begins to roll down the hill, it loses potential energy, but gains kinetic energy.

The first trophic stage of a food chain, which contains the most energy, is made up of the green plants with in ecosystem known as producers.
What is Trophic level of Food chain?The term "trophic level" refers to an organism's place in the food chain and has a range of one for primary producers to 5 for humans and marine mammals. The mean trophic level of the consumer's prey is multiplied by one to determine the consumer's trophic level.
The trophic levels are divisions into which species in food webs get categorised. These levels can be roughly categorised as producers (first trophic level), consumers, and decomposers (last trophic level). The first trophic level is producers. The first trophic level receives 100% of the energy from the sun, which has the greatest amount of energy, while subsequent trophic levels only receive 10% of the energy of the level before them.
Thus, the first trophic stage of a food chain, which contains the most energy, is made up of the green plants with in ecosystem known as producers.

Why do you seldom see fossils in metamorphic rocks?
Answer:
Metamorphic rocks have been put under great pressure, heated, squashed or stretched, and fossils do not usually survive these extreme conditions.
Explanation:
Fossils are found in metamorphic rocks because metamorphic rocks have been put under great pressure, heated, squashed or stretched, and fossils do not usually survive these extreme conditions.
What are metamorphic rocks?Metamorphic rocks arise from the transformation of existing rock to new types of rock in a process called metamorphism. The original rock is subjected to temperatures greater than 150 to 200 °C and, often, elevated pressure of 100 megapascals or more, causing profound physical or chemical changes.
Metamorphic rocks started out as some other type of rock, but have been substantially changed from their original igneous, sedimentary, or earlier metamorphic form.
Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.

Which of the following is an example of descent with modification
This will lead to change in populations over generations in a process that Darwin called descent with modification. ... One of the best examples has been demonstrated in the very birds that helped to inspire Darwin's theory: the Galápagos finches.
a mechanism for evolution; all organisms are related through descent from an ancestor; descendants accumulated adaptations; descent of all organisms from an ancestor that lived in the past; descendants accumulated diverse modifications (adaptations)
if the first one doesnt work try the second
An example of descent with modification is a bacterium that inherits a gene for antibiotic resistance, has a more significant possibility of survival. Natural selection then applies that resistance through the population, forcing scientists to come up with a new antibiotic.
What is darwin's theory of descent with modification?Darwin described evolution as "descent with modification," the theory that species evolve over time, give rise to new species and transmit a common progenitor.
The means that Darwin proposed for evolution is natural selection.
Thus, a bacterium that inherits a gene for antibiotic resistance, is an example of descent with modification.

Answer:
Cellular Respiration.
Explanation:
Explain why the blood vessels and the heart are not made of the same type of muscle even though they are both involuntary.
Answer:Each muscle in the body is made up of cells called muscle fibers. Muscle fibers are long, thin cells that can do something that other cells cannot do—they are able to get shorter.
Explanation:
IM not sure if this would help but their you go.
Muscle fibers are the cells that make up each muscle in the body. Muscle fibers are long, thin cells with the unique ability to shrink. Most cells cannot do this.
What are Muscle fibers?Cross-striations are the most noticeable histological characteristic of muscle fibres, which are massive multinucleated cells. Many myofibrils with tiny cylinders made of bundle of myofilaments can be found in the cytoplasm.
Myofilaments are made up of both thick filaments primarily made of myosin and thin filaments primarily made of actin. Due to their regular overlap, which is kept in register from across diameter of the muscle fiber, the thick and thin filaments create the cross-striations.
Thus, the cells that make up each muscle in the body are known as muscle fibres. Long, thin cells called muscle fibres have the unusual ability to contract and expand. Most cells are unable to achieve this.
