What is the law that states “energy cannot be created or destroyed it can only change to different forms”?
A.Law of Conservation of Energy
B.Law of Conservation of Matter
C.Law of Gravity
D.Law of Physics
Answer:
A. Law of Conservation of Energy
Explanation:
The first law of thermodynamics, also known as Law of Conservation of Energy, states that energy can neither be created nor destroyed; energy can only be transferred or changed from one form to another. ... In other words, energy cannot be created or destroyed.
Law of Conservation of Energy is the law that states energy cannot be created or destroyed it can only change to different forms.
What do you mean by conservation of energy?The law of conservation of energy states that the amount of energy is neither created nor destroyed. For example, when you roll a toy car down a ramp and it hits a wall, the energy is transferred from kinetic energy to potential energy.
The law of conservation of energy states that energy can neither be created nor destroyed - only converted from one form of energy to another. This means that a system always has the same amount of energy, unless it's added from the outside.
The principle of energy conservation states that energy is neither created nor destroyed. It may transform from one type to another.

In the human body, food is transformed into various kinds of energy. The nervous system consists of many cells called neurons. These neurons send electrical signals across the body. This means that in some parts of the human body, the energy transformation is:
Electrical to chemical
Chemical to electrical
Radiant to chemical
Radiant to electrical
Answer:
The chemical energy
Explanation:
The chemical energy stored in food is a type of potential energy. Therefore, it can be transformed into kinetic energy. This transformation happens during chemical reactions that take place when the body digests food.
hope this helps
Answer:
Chemical to Electrical
Explanation:
The answer is B, because if you think about it, people always say you need to eat food to get energy, so you would be able to move. This saying comes in use in this question, as the food provides Chemical Energy, and gets transferred to Electrical Energy, to help you move around.

One of the researchers thinks it should be classified in the plant kingdom while the other researcher believes it should be in the animal kingdom. Using what you have learned about how the organisms are classified, explain how you would classify the organism and why.
Answer:
It should be classified in the animal kingdom.
Explanation:
This organism should be in the animal kingdom classification. Why? Well, in the text it gives us a big clue: "eats food for energy." Plants use the sun for their energy, and make their own food (photosynthesis). But, animals on the other hand do eat food for energy. There is no way that this organism is a plant if it eats food for energy. The other researcher who thinks it is a plant probably thought so because this organism is green, and probably thought "Oh! Chlorophyll must have caused the green color" (Chlorophyll/green color in plants is a PLANT characteristic), but this researcher was wrong and the green color was not caused by chlorophyll.
Answer:
Chlorophyll, like in this cross section of Plagiomnium affine laminazellen is a key component in the process of photosynthesis, which sustains plant life and produces oxygen for the entire planet. Although microscopic in size, chloroplasts like these have a big role to play in the health of the planet.

Bird feeders can be found in backyards around the globe. Some people like to watch as the birds flock to the feeders and peck at the seeds. Others may like the idea that they are offering a service by feeding the local birds in their neighborhood. But do bird feeders help native populations of birds? A recent study suggests that bird feeders may do more harm than good by increasing competition for food.
A team of scientists in New Zealand observed that bird feeders may be attracting more invasive, or non-native, birds. They conducted an experiment to see if this observation could be supported with data. The scientists set up 23 bird feeder locations scattered around urban areas. Food in the form of mixed bird seed and bread was offered daily at 11 experiment locations. "Twelve locations were left alone, without food, to serve as a control group. The number of birds that visited each location was counted daily. The study went on for almost two years. After analyzing the data, scientists discovered that the 11 experimental bird feeders attracted two to three times the number of invasive species of birds as the control group feeders. The control group feeders had approximately equal numbers of native and invasive birds visit them. The team of scientists noted that the increase in invasive species may have been due to the food choices that were offered at each feeder. Native birds typically eat fruit, nectar, and insects. Invasive birds were more attracted to the mixed bird seed and bread. The data supported the conclusion that backyard bird feeders were not helping native bird populations and suggested that invasive species are pushing out native species in competition for food.
The team of scientists also noted that they are not suggesting that people stop feeding the birds. They just want people to be aware of the types of food they offer and how often they fill the feeders. Making better choices in backyard feedings may help increase the number of local birds that visit while decreasing visits from invasive species.
Conducting backyard bird feeder experiments is a great way to see which local birds and which invasive birds are in your neighborhood. The more you know about the local bird populations and their food preferences, the better equipped you are to support them in a more positive way.
THE QUESTION------ How did the backyard bird feeders in the article increase competition in that ecosystem?
Answer:
birds don't like loud sounds and if its in the back yard the cars that go by wont effect the birds wane they take a bath
Explanation:
answer:
the backyard bird feeders in the article increased competition in that ecosystem because when those people put out feeders, it was a competition to the birds as in who would get the best food and also bird feeders usually only supply seeds which not all birds eat. as stated in the passage, native birds typically eat fruit, nectar, and insects, while invasive birds were more attracted to the mixed bird seed and bread. so the competition was that all birds who come by the feeders will not get the food that they may need to survive.

Answer: A. Anticline
B. Syncline
Explanation:
A convex upward fold is referred to as an anticline, and a concave upward fold is referred to as a syncline. In contrast, a synclinorium is a big syncline on which tiny folds are superimposed, while an anticlinorium is a massive anticline.
What Anticline and Syncline act as landforms?Anticlines are folds that are curved upward to generate ridges, while synclines are curved downward to form troughs. Typically, anticlines and synclines are constructed of numerous folded rock units. The nose is the end of a fold.
The downwards arc or curve of a fold is known as a syncline. In geology, a fold is a bend in a rock stratum brought on by forces deep inside the earth's crust. Folds are brought about by a variety of factors, from small variations in crustal pressure to significant collisions of tectonic plates.

1. Where does the body get glucose molecules?
2. Where does the body get amino acids?
3. Where does the body get oxygen?
4. What do you think could happen if the human body doesn’t take in one or all of these molecules? Why do you think this?
Answer:
1.This energy comes from the food we eat. Our bodies digest the food we eat by mixing it with fluids (acids and enzymes) in the stomach. When the stomach digests food, the carbohydrate (sugars and starches) in the food breaks down into another type of sugar, called glucose.
2.Humans can produce 10 of the 20 amino acids. The others must be supplied in the food. Failure to obtain enough of even 1 of the 10 essential amino acids, those that we cannot make, results in degradation of the body's proteins—muscle and so forth—to obtain the one amino acid that is needed.
3.The oxygen enters the bloodstream from the alveoli, tiny sacs in the lungs where gas exchange takes place (Figure below). The transfer of oxygen into the blood is through simple diffusion. The oxygen-rich blood returns to the heart.
4. If the human body doesn't take in one or all of these molecules we'll simply die or we'll be in severe health issues. We use glucose as a form of energy, if we don't take in any energy we'll die. We need amino acids to help break down food in our body, if we don't we'll be in very severe health issues. And of course we need oxygen to be alive. We need oxygen for respiration and photosynthesis to take place. We also need oxygen to burn the fuel in our body to produce energy.
hope this helps and have a great day:)
Glucose molecules are energy carrying molecules that provides the body with the necessary energy that it requires to function properly and a very important source of glucose is Carbohydrate rich foods like maize.
While amino acids are necessary for the proper functioning of the Human system and also a second source of energy. A very important source of the amino acid is animal protein.
When any of these molecules are missing the human body cannot maintain homeostasis which will result in severe health conditions and death.
Hence we can conclude that the body gets glucose from carbohydrate foods, amino acids from animal protein and oxygen from the atmosphere.

Using what you read in today's slides, determine whether you feel each piece of evidence from Elisa is sufficient or insufficient.
Evidence A: Elisa's sleep journal shows that she has gotten, on average, 9 hours of sleep each night for the past month.
1. Would you consider this evidence sufficient or insufficient? *
A. Sufficient
B. Insufficient
2.Why? Please explain.
Evidence B: The night before she came into the office, Elisa slept 7 hours.
3. Would you consider this evidence sufficient or insufficient? *
A. Sufficient
B. Insufficient
4.Why? Please explain.
Evidence C: Elisa kept a food journal for a month. Her journal shows that each day she ate between 6 and 8 servings of food with starch and between 2 and 4 servings of food with protein every day.
5.Would you consider this evidence sufficient or insufficient? *
A. Sufficient
B. Insufficient
6. Why? Please explain. *
Evidence D: Elisa ate a lot of starch yesterday but still felt tired.
7. Would you consider this evidence sufficient or insufficient? *
A. Sufficient
B. Insufficient
8. Why? Please explain.
Evidence E: On the day before she began her journal, Elisa said she always felt tired even though she ate well and slept a lot at night.
9. Would you consider this evidence sufficient or insufficient? *
A. Sufficient
B. Insufficient
10. Why? Please explain. *
1.a
I would presume this to be sufficent due to the fact that Elisa's sleep journal states that she has gotten 9 hours of sleep for the past month thus she is having the same amount of sleep and there is probably another conclusion.
2.b
this information is not sufficient because there is the only information of the amount of time that she slept the night before she went to the office and there could have been a different amount of time that she slept the days before therefore making this information insufficient.
3:a
this information is sufficient because Elisa states the amount of servings that she eats and tells the number of servings that have either protein or starch.
4.b
this is insufficient evidence because there is no information telling what else Elisa ate and what type of food it was which could have been a factor of her being tired.
5.b
I would consider this evidence as insufficient because Elisa only states that she ate well and slept a lot rather than stating the amount of time that she slept and the type of food that she ate because those can be a factor in her feeling tired.

Activity 1
Reread the last two paragraphs of the “Energy Inventions” article below and highlight evidence that supports or goes against the claims:
Comparing Solutions
Using solar energy and capturing energy from humans are just some of the exciting ways people are using science to solve energy problems. There is no perfect solution, however. Solar energy relies on the sun and doesn’t work as well in the dark or on cloudy days. For example, if you were using your Little Sun to read at night and it ran out of energy, you would need to wait for the sun to come up so that more energy could be captured and transferred to the battery in your light. Just imagine if the next day was very cloudy! Your energy system would not be able to capture very much energy from the sun, so your light would not stay on for long.
The Little Sun lamp and the Hollow Flashlight have something in common: they get energy from somewhere else instead of making it themselves. In fact, that’s true of every object in the universe. Engineers must think about energy sources as they design their inventions. They must find an energy source that will do a good job of transferring energy to the object. The Little Sun lamp gets energy from the sun, while the Hollow Flashlight gets energy from the human body. There are many other possible energy sources to consider. For example, some devices transfer kinetic energy (energy of motion) from wind, water, or even people to power devices! There isn’t a single right way to provide energy when there’s no electrical grid available, and each source has its strengths and drawbacks. Which energy source would YOU choose?
Which claim do you think is most convincing based on the evidence you have gathered so far?

Example:
Strawberry plants reproduce asexually through runners in the soil that sprout to create new strawberry plants.
After asexual reproduction, the newly produced organism will look identical to the parent being as only one parent was involved, therefore only one set of genes was introduced not making a genetic differece.
