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.

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?

The process of hearing is very complex. Sound waves travel into the ear canal until they reach the eardrum. The eardrum passes the vibrations through the middle ear bones into the inner ear. The inner ear is also called the cochlea. Inside the cochlea, there are thousands of tiny hair cells. Hair cells change the vibrations into electrical signals that are sent to the brain through the hearing nerve. The brain tells you that you are hearing a sound and what that sound is.
What energy transformations occur between entering the ear and the brain?
Electrical energy to sound energy to mechanical energy
Sound energy to mechanical energy to electrical energy
Mechanical energy to electrical to sound energy
Sound energy to electrical energy to mechanical energy
Answer:

The mode of reproduction that requires a single parent and produces offspring that are genetically the same as the parent is -
asexual reproduction
sexual reproduction
unicellular reproduction
prokaryotic reproduction
Answer:
Asexual reproduction
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.

Two researchers have discovered a new organism. It is made of multiple cells, has a nucleus in each cell, and eats food for energy but it's green in color. 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.Two researchers have discovered a new organism.

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.

A: Anticline, syncline, or fault-block mountain
B: Anticline, plateau, or syncline
Giving 50 points
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.
Therefore, A. Anticline B. Syncline

What are the three variables and what can they do? explain.
Answer:
There are three main types of variables in a scientific experiment: independent variables, which can be controlled or manipulated; dependent variables, which (we hope) are affected by our changes to the independent variables; and control variables, which must be held constant to ensure that we know that it's our manipulation of the independent variable causing the change in the dependent variable. Using these variables correctly helps scientists measure cause and effect in scientific experiments and allows scientists to manipulate cause and effect to produce desired outcomes.

Which of the these combinations result in the expression of a recessive trait?
a. two dominant alleles
b. A Y chromosome
c. two recessive alleles
d. a dominant allele and a recessive allele
The combination of two recessive alleles results in the expression of a recessive trait. So the correct option is C.
What is the law of dominance?
The law of dominance was given by Sir Gregor Mendel. The law states that ‘In crossing between homozygous organisms for contrasting characters of a pair, only one character of the pair appears in the first generation.’
This law of dominance was the first law of heredity that was proposed from the findings of Mendel. It studies the characters and explains that all characters present in an individual organism are controlled by separate units called factors. These factors are present in pairs.
These pairs can be homozygous or heterozygous. In the case of heterozygous pairs, only one of the factor present will dominate the other. The dominating character is called the dominant character, and the unexpressed character is the recessive character.
The recessive character is latent, but it is transmitted to the offspring in the same manner as the dominant character is transmitted. The recessive character will only be expressed when the offspring receives both copies of the same allele and this results in a homozygous individual.
Therefore the correct option is C.

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.
