Answer:
Regular, non-fluorescent colors appear to our eyes when objects absorb some wavelengths of light, and reflect others. For example, a yellow pencil looks yellow because its paint reflects the wavelength of yellow light, and absorbs the other wavelengths.Mar
Answer:
Heat
Explanation:
In the iron where electric current is used to heat water, electrical energy is converted to heat energy which is boils the water to steam.
Electrical energy is due to the movement of current within a circuit. The heat produced by the electrical energy is transferred to the water.
This in turn forms steam which is used for the ironing processes.
Heat energy is generated when the average kinetic energy of the molecules in a system increase.
Explanation: The given compound is an organic compound because it has hydrogen and carbon atoms in it.
Skeletal structure of an organic compound is defined as a structure which is composed of the skeletal atoms that are used to define a structure.
In organic chemistry, the skeletal atoms are hydrogen and carbon. The atoms other than hydrogen and carbon are termed as heteroatoms and are shown in the structure.
The skeletal structure of 3-methyl-1-butanethiol is given in the image attached.
Here, the functional group is thiol group which has a heteroatom S.
1) Organic matter is recycled in an ecosystem by decomposers. Decomposers are organisms such as bacteria and fungi that break down the organic matter in the dead bodies of plants and animals. As the decomposers feed from the dead animals, they break down the organic compounds into simple nutrients.
2) By removing the jaguar from the food web, we are removing one of the predators. This can cause a surplus in both the population of the mammals ( rabbit and the other one) because there is not something that is actively eating and keeping the numbers at bay. Essentially, if you remove the jaguar you will mess up the loop, causing an increase of population that could possibly cause harm. Also, by taking the jaguar out of the food web, the decomposers would not be able to decompose fecal, animal carcasses, etc. because the jaguar is not actively killing something and furthering along this process. Hope this helps!
