Answer:
Without fires, there would be no life on Earth
. Fires are key to maintaining the proper oxygen concentration in the atmosphere; fire regulates the carbon cycle and life, as we know it, is based precisely on carbon
Explanation:
Although we tend to think of fires as a human invention that kills plants, animals, people, fire, as with rain or wind, is an essential natural component, basic to maintain the planet's biodiversity.
As for example, grassland ecosystems are also benefited by the same fires that allow renewal, and generate natural sustainability on the earth through the carbon cycle.
Answer:
The strands of mRNA move through the ribosome from A site to the P site and exist at E site. The molecules of tRNA bind to the molecules of mRNA at the A site before moving P site where amino acids are attached to the end of the growing peptide chain.
Explanation:
Answer: Mitochondria
Explanation:
The power house of the cell is known as Mitochondria. The energy that is required by the body is provided by mitochondria.
The hydrolysis of the ATP takes place in which it is converted into ADP and Pi and some amount of energy is released.
This energy is used by the body for the various types of metabolic activities. The site of ATP formation is mitochondria.
Answer:D, how relatively little genetic change could lead to the significant differences we see between ourselves and chimps. 3 mya-2 mya. You inherited from your mom both her crooked nose and her recipe for chocolate chip cookies (both favorable traits).
Explanation:Neoteny is the retention, by adults in a species, of traits previously seen only in juveniles, and is a subject studied in the field of developmental biology. In neoteny, the physiological (or somatic) development of an animal or organism is slowed or delayed. You inherited from your mom both her crooked nose and her recipe for chocolate chip cookies (both favorable traits).
Plant cells have plastids and larger vacoule and they also have tough cellulosic cell wall outer to cell membrane as a covering.
Animal cells don't have cell wall rather they have cell membrane as it's outermost covering and they have smaller vacuoles.They also don't have plastids.They have centrosome which is not found in plant cells.
