SC.8.L.18.4A student picked up Ball A off a shelf and threw it. In this action light energy from the sun is transformed into chemical energy through photosynthesis in food. The chemical energy stored in the student was transformed into mechanical energy as he/she used her muscles to throw the ball. How does this action support the Law of Conservation of Energy?
A. Energy was not conserved in this example because the light energy is no longer available.
B. Energy was conserved because the light energy was transformed into various forms in the process.
C. Energy was conserved because different forms of energy were created at various stages in the process.
D. Energy was not conserved because the light energy from the sun was destroyed as the chemical energy was gained through eating.
Answer:
B. Energy was conserved because the light energy was transformed into various forms in the process.
Explanation:
Law of Conservation of Energy states that energy cannot be created nor destroyed. However, it can transform into other types of energy. B is the only answer that follows the Law of Conservation of Energy.
As you move to a higher elevation (e.g. in the mountains), the air pressure drops significantly. In turn...
the temperature of water increases and the density goes up as well.
the temperature of water drops and the density of it goes down as well.
the evaporation rate of water increases at all temperatures causing an increase in volume.
the evaporation rate of water decreases at all temperatures causing a decrease in volume.
Answer:
the temperature of water drops and the density of it goes down as well.
Explanation:
The higher the altitudes, the lower the temperature.
At high altitudes, molecules tend to be more spread out, so the density of the molecules decrease.

A plant seed is formed from:
a fertilized egg
growth of an egg
growth of a spore
a mature pollen
Answer:
D. a mature pollen
Explanation:
Answer:A plant seed is formed from a fertilized egg.
What is a seed?A seed is an embryonic plant enclosed in a protective outer covering. The formation of seed begins with fertilization, which occurs when the pollen from the male reproductive organ (stamen) fuses with the female reproductive organ (pistil). The fertilized ovule develops into a seed that contains the embryonic plant and a supply of nutrients to support its initial growth until it can begin photosynthesis. The seed coat is the outer covering that protects the embryo from desiccation, disease, and physical damage.

1. What are the optimal conditions needed for this severe weather events?
2. How do you think people who live in the regions where tornados are most common can prepare themselves for such an event?
Answer:
Severe weather can occur under a variety of situations, but three characteristics are generally needed: a temperature or moisture boundary, moisture, and (in the event of severe, precipitation-based events) instability in the atmosphere.
Every year in the United States, tornadoes do about 400 million dollars in damage and kill about 70 people on average. Extremely high winds tear homes and businesses apart. Winds can also destroy bridges, flip trains, send cars and trucks flying, tear the bark off trees, and suck all the water from a riverbed.

Describe the amphibian life cycle. Include the different phases and traits of each phase.
Answer:
Another Brainly Answer
Explanation:
The Amphibian life cycle isn't as simple as it seems. The main Amphibian that has a longer process are called Frogs. Everyone knows frogs, but they are different from most animals such as turtles. The first stage of frogs are when their in eggs of course. These eggs are called "Tadpoles" and look different than most eggs. These eggs are kept in water until they grow. Which brings me to the next stage. When the tadpoles hatch you would start to see something like a baby fish swimming around. That's still the same tadpoles you saw before just hatched. When it comes to this topic most are confused because frogs don't have tails. Well during these stages a tail is used to help them survive in the water and move around. The third stage of these interesting creatures are when they grow legs. That's when they are able to walk on land. They still have their tail of course. It still helps them swim in water. I don't understand much about why they still have a tail if they've grown legs, but that's for me to find out soon. Eventually they grow more and more and get better with their legs and lose the tail. Well the tail doesn't just magically disappear. It's actually absorbed by using something called apoptosis. Then it's pretty much and adult frog.
Describe the three types of mammals. Give examples of each. How is reproduction/offspring different in each?
Answer:
1) Monotremes are mammals that lay eggs. The only monotremes that are alive today are the spiny anteater, or echidna, and the platypus. These mammals are really different from other mammals. Their body temperature is lower than most warm-blooded animals, a feature that has more in common with reptiles. Their name comes from the fact that they have only one body opening for both wastes and eggs to pass through.
2) Marsupial mammals give birth to babies that are not completely developed. The babies are very tiny. The babies then crawl up the fur on the mother's belly into a pouch on the outside of the mother's abdomen. The babies drink milk from the mother and continue to develop inside the pouch. Koalas, kangaroos, wallabies, and opossums are some of the better-known marsupials.
3)A placental mammal develops inside its mother's body until its body systems can function on their own. The name of this group comes from the placenta, an organ in pregnant female mammals that passes materials between the mother and the developing baby. Food and oxygen, carried by blood, pass from the mother to the baby through the placenta. Most mammals, including humans, are placental mammals.

Memories of a Memory
Have you ever witnessed something amazing, shocking or surprising and found when describing the event that your story seems to change the more you tell it? Have you ever experienced a time when you couldn't really describe something you saw in a way that others could understand? If so, you may understand why some experts think eyewitness testimony is unreliable as evidence in scientific inquiries and trials. New insights into human memory suggest human memories are really a mixture of many non-factual things.
First, memory is vague. Imagine your room at home or a classroom you see every day. Most likely, you could describe the room very generally. You could name the color of the walls, the floors, the decorations. But the image you describe will never be as specific or detailed as if you were looking at the actual room. Memory tends to save a blurry image of what we have seen rather than specific details. So when a witness tries to identify someone, her brain may recall that the person was tall, but not be able to say how tall when faced with several tall people. There are lots of different kinds of "tall."
Second, memory uses general knowledge to fill in gaps. Our brains reconstruct events and scenes when we remember something. To do this, our brains use other memories and other stories when there are gaps. For example, one day at a library you go to quite frequently, you witness an argument between a library patron and one of the librarians. Later, when telling a friend about the event, your brain may remember a familiar librarian behind the desk rather than the actual participant simply because it is recreating a familiar scene. In effect, your brain is combining memories to help you tell the story.
Third, your memory changes over time. It also changes the more you retell the story. Documented cases have shown eyewitnesses adding detail to testimony that could not have been known at the time of the event. Research has also shown that the more a witness's account is told, the less accurate it is. You may have noticed this yourself. The next time you are retelling a story, notice what you add, or what your brain wants to add, to the account. You may also notice that you drop certain details from previous tellings of the story.
With individual memories all jumbled up with each other, it is hard to believe we ever know anything to be true. Did you really break your mother's favorite vase when you were three? Was that really your father throwing rocks into the river with you when you were seven? The human brain may be quite remarkable indeed. When it comes to memory, however, we may want to start carrying video cameras if we want to record the true picture.

Why do you think the western gorilla’s hands are shaped the way they are? What does the western gorilla use its hands to do?
why do you think the European mole’s hands are shaped the way they are? What does the European mole use its hands to do?
Explanation:
Gorilla: This is very hard to think about but to like help support the the gorillas body when it's like doing that with its hands
Mole: The way there hands are built, it can easily claw it's way through the ground and get places easier.
Both the animals hands might be shaped the way they are due to the required adaptation for their own environment as it differs from place to place. The gorilla may use their hands to have a faster way of transportation as they move to foraging.
What is foraging?Foraging is a behavior which includes all the methods by which an animal acquires and utilizes sources of energy and nutrients. This also includes the location and resources consumption, as well as their recapture and storage, within the context of the larger community.
The european mole's hands are in that shaped due to the need of survival and to build their shelter. The european mole may use their hands to dig to provide themselves a safe shelter and to hide from predators.
