Answer:
Trout is a very common freshwater fish. The lifespan is very small.
Explanation:
The trout population is affected by the climate change and also the pollution present in the freshwater. These fish variety travel for across to lay eggs. And after laying eggs they just die. The climate change and the the fishing of this variety has negatively affected the population. There are lot of varieties of trout fish like rainbow albino etc.
The rise in temperature and flood in a river is a major factor which effects the population of this fish. in USA when the temperature rises it result in flood condition in the river which affects the lifestyle of this fish.
Answer:
Ultraviolet wavelength have the highest energy.
Explanation:
Ultraviolet radiation is an electromagnetic radiation. Its wavelength is 10 nanometers to 400 nanometers. It contribute about 10 percent of sunlight radiation. Wavelength of visible light starts from 400 nanometers so wavelength of Ultraviolet radiation is shorter than visible light but longer than X rays because X rays has a wavelength between 0.01 to 10 nanometers.
Answer:
a)This is RNA polymerase performing transcription
Explanation:
We can see that the purple molecule is attached to a DNA molecule, and is producing an mRNA molecule from a template strand. This is the process of transcription
The enzyme that carries out the synthesis of an mRNA molecule is RNA polymerase.
If the molecule was a ribosome performing translation, we would expect a polypeptide chain to be produced rather than an mRNA, and that the template molecule would be mRNA
If the molecule was DNA polymerase, it would synthesising a DNA strand not mRNA
If the molecule was a DNA repair enzyme, it would be correcting errors, not synthesising mRNA.
Answer:
Earth formed about 4.6 billion years ago during the birth of our solar system. ... During the next major phase of earth's formation cooling and differentiation of the Earth's layers occurred. Dense materials sank to the center, forming an iron-nickel rich core. Lighter buoyant silicate-rich magma rose to the surface.
Explanation:
Calcite or Aragonite.<span>
Limestone is in
form of sedimentary rock that is made up of skeletal fragments of marine
organisms such as forams, corals and molluscs. However, limestone is formed
from the shell of an organisms because the shell is made up of calcite or
aragonite.</span>
