This answer provides 10 examples each of conduction, convection, and radiation. It also explains whether combustion reactions are exothermic or endothermic, and provides an example of a substance with a higher specific heat than liquid water.
Explanation:Conduction:1. Touching a hot stove and feeling heat transfer to your hand
2. A metal spoon becoming hot when placed in a cup of hot soup
3. A pan heating up when placed on a stove burner
Convection:
1. Boiling water in a pot on a stove
2. Wind blowing and causing heat transfer in the atmosphere
3. A radiator heating a room by transferring heat to the air
Radiation:1. Feeling the warmth of the sun on your skin
2. A campfire warming your body by emitting heat
3. A microwave oven cooking food by emitting electromagnetic waves
Combustion reactions:Combustion reactions are exothermic, meaning they release heat. This is because combustion reactions involve the rapid combination of oxygen with a fuel, such as burning wood or gasoline. The release of energy in the form of heat is what makes combustion reactions exothermic.
Specific heat:A substance with a specific heat higher than liquid water is ethylene glycol (antifreeze). Specific heat is the amount of heat needed to raise the temperature of a substance by a certain amount. Ethylene glycol has a higher specific heat than water, which means it can absorb more heat energy before its temperature increases significantly.

What prevents wind from blowing a straight line from the north pole to the equator
Answer:
The Coriolis force
Explanation:
The wind generally blows from a region of high pressure to a region of low pressure. This wind when blows in a much larger scale, that is moving from the polar region to the equatorial region, it gets deflected towards the right due to the earth's rotation about ts own axis. This effect is called the Coriolis force.
The Coriolis force is the force that occurs due to the continuous rotation of the earth. Due to this effect, the wind in the northern hemisphere moves in a clockwise pattern, whereas in the southern hemisphere, it moves in an anticlockwise direction.
What best describes a difference between prokaryotes and eukaryotes
Comparisons of cranial capacity between A. africanus and the later species H. erectus and A. boisei show that H. erectus had much larger brains, while A. boisei had only slightly larger brains, than A. africanus. There is evidence that A. africanus and H. erectus used tools, though the tools made by H. erectus required more skill and planning to craft. How do you think the toolmaking abilities of A. boisei would have compared?
(A)A. boisei would have had very little ability to make tools, unlike the other two hominids.
(B) A. boisei would have been able to make more advanced tools than the other two hominids.
(C)A. boisei would have been able to make tools that were less advanced than H. erectus.
(D)A. boisei would have made tools that were less advanced than those made by A. africanus.
Ans.
According to the study, H. erectus had a larger brain as compare to A. boisei and A. africanus, while A. boisei had a larger brain than A. africanus. It means the H. erectus had much advanced tool-making abilities as compared to A. boisei, so A. boisei would have been able to make less advanced tools than that of made by H. erectus.
Thus, the correct answer is option (C).
There are different kinds of studies. The toolmaking abilities of A. boisei would have compared to the A. boisei would have been able to make tools that were less advanced than H. erectus.
Based on the study carried out, H. erectus is known to have a larger brain when compare to A. boisei and A. africanus and also the A. boisei also has a bigger brain when compared to A. africanus.
This implies that the H. erectus has high abilities in terms of tool-making than A. boisei. Boisei is known to be a Latin word that implies 'strongly built' which connote a specie that has a robust skulls and jaws.

The Earth was never flat according to scientific discoveries. Copernicus challenged the Ptolemaic model with his heliocentric theory.
Explanation:The idea that the Earth was flat was a common belief in ancient times, but it was eventually disproven. The Ptolemaic model, which was widely accepted before the discoveries of Kepler, Copernicus, Galileo, Newton, and others, believed that the solar system revolved around the Earth. However, Copernicus challenged this view with his heliocentric theory, which proposed that the sun, not the Earth, was at the center of the universe.

Which of the following is NOT an example of absolute dating?
Carbon-14 dating
Uranium-235 dating
Using the law of superposition
Using evidence to find the actual age of something.
OPTION C. Using the law of superposition
Carbon-14 dating and Uranium-235 dating are examples of absolute dating methods while using the law of superposition falls under the category of relative dating methods since it can place fossils in a sequential format but cannot provide their actual age.
Explanation:The subject of absolute dating refers to the process of determining an age in years for geologic materials. This method relies on quantifying something that is undergoing a process at a known rate. Carbon-14 dating and Uranium-235 dating are examples of such methods where the half-life of a radioactive isotope is used to determine the age of a rock or a fossil.
However, using the law of superposition is not an example of absolute dating but an example of relative dating. The Law of Superposition suggests that in undisturbed sedimentary rock layers, the oldest layer will be at the bottom, and the youngest will be at the top. In other words, it does not provide an actual numeric age, but places rocks and events in their sequence of formation.

Carbohydrates have different structures, depending on their function in the body. Simple carbohydrates can provide immediate energy, while complex carbohydrates provide a longer-term energy source. Diabetes is a disease in which the body has difficulty regulating the amount of sugar in the blood. Individuals with type 1 diabetes do not produce enough insulin, the hormone that regulates blood sugar, and must take regular doses of additional insulin. However, if the body gets too much additional insulin, it can cause the individual’s blood sugar level to be too low and give them insulin shock. Individuals with type 1 diabetes often carry food like juice or candy with them to get their blood sugar levels up quickly in case of insulin shock. What carbohydrate structure do these foods have that makes them so efficient at treating insulin shock? A; simple carbohydrate
B; complex carbohydrate
C; structural carbohydrate
D;excess carbohydrate
Quick sources of sugar like juice or candy make an efficient treatment for insulin shock in individuals with type 1 diabetes because they contain simple carbohydrates. These simple carbohydrates, or simple sugars, are rapidly absorbed into the bloodstream owing to their simple molecular structure which results in a quick increase in blood sugar levels.
Explanation:Individuals with type 1 diabetes often carry quick sources of sugar, like juice or candy, in case of insulin shock. Insulin shock can occur when their blood sugar levels drop too low. These foods make an efficient treatment because they contain simple carbohydrates. Simple carbohydrates, or simple sugars, such as glucose and fructose, are easily and quickly absorbed into the bloodstream, owing to their simple molecular structure. This causes a rapid spike in blood sugar, which can effectively combat the dangerously low blood sugar levels of insulin shock. Thus, the correct answer is A; simple carbohydrate.
