Cellular respiration uses oxygen to release the energy stored in food.
Explanation:
In breathing living organisms take oxygen and release the carbon dioxide it is similar to the aerobic respiration.
There are two types of respiration:
1. Aerobic respiration
2. Anaerobic respiration
Aerobic respiration
It is the breakdown of glucose molecule in the presence of oxygen to yield large amount of energy. Water and carbon dioxide are also produced as a byproduct.
Glucose + oxygen → carbon dioxide + water + 38ATP
Anaerobic Respiration
It is the breakdown of glucose molecule in the absence of oxygen and produce small amount of energy. Alcohol or lactic acid and carbon dioxide are also produced as byproducts.
Glucose→ lactic acid/alcohol + 2ATP + carbon dioxide!
Answer:
Lightyears
Explanation:
When dealing with very large interstellar distances, astronomers do not use the regular miles, kilometers, or meters we are used to. This is because they are just too small to be used as a metric when measuring such large distances. As a matter of fact, the earthly number system will quickly be exhausted when trying to measure some of these interstellar distances.
Instead, astronomers make use of Lightyears. Lightyears are defined by the distance traveled by an object moving at the speed of light if it was moving constantly at that speed for one year.
This can properly be used to estimate interstellar distances. since its value is very large. 1 lightyear = 9,461,000,000,000 Km
If we say that our closest star is 9 lightyears away, we are saying that it will take an object moving at the speed of light 9 years to travel from that star to our planet.
Answer:
it reflects green light and absorbs other colors.
Explanation:
The term pigment derives from the Latin pigmentum, which means the <em>substance that produces color</em>.
Pigments provide color to cells and tissues.
In vegetables, we can find different pigments, such as chlorophyll or carotenoids, among others. Plants use these pigments during the photosynthesis process to absorb sunlight and fixate carbon dioxide. Stem, flowers, and other tissue have pigments in their cells that define the organ´s colors.
Pigments are chemical molecules that produce color by the selective absorption of sunlight. Whenever white light meets a pigment, some wavelengths are absorbed by the pigments while others are reflected. The color expressed is the product of the reflection. The reflected spectrum is perceived as color and determined to be the pigment color or the color of an object or organism.
The color that tissue or vegetal organ express will depend on the pigment concentration or the combination of many of them.
The green color is ordinary in most vegetable species. Chlorophyll is responsible for this coloration, present in almost every vegetable species. This pigment absorbs blue and red wavelengths. But they reflect spectrums of green wavelengths, meaning that the expressed color is green in different tones.
Answer:
Explanation:
Nucleotides are building blocks of nucleic acids (DNA and RNA). A nucleic acid contains a chain of nucleotides linked together with covalent bonds to form a sugar-phosphate backbone with protruding nitrogenous bases. For example, DNA contains two such chains spiraling round each other in the famous double helix shape.
They're called autotrophs. Is that what you're looking for?
