The answer is about 540-490 million years ago.
Deoxyribonucleic acid (DNA) is the hereditary material that lies within the nucleus of all cells in humans and other living organisms. Most of the DNA is placed within the nucleus and is called nuclear DNA.
A chromosome is made up of two chromatids which are joined by the centromere. The chromatids separate from each other during mitosis to form two new chromosomes. The DNA making up a chromosome is dispersed as chromatin.
Under a microscope, chromatids look like little dots and chromosomes are lines.
Answer:
Plankons, fungi, bacteria, lichens etc. are the pioneer species of ecological succession. Pioneer species are hardy species which are the first to colonize previously biodiverse steady-state ecosystems. Some lichens grow on rocks without soil, so may be among the first form of life the example includes bacteria, fungi, and lichens.
Explanation:
The molecule that is formed by energized electrons in the cell respiration electron transport chain is ATP MOLECULES.
ATP is the energy currency of the cells, that is, it is the only form of energy which living cells can use to power their biochemical activities. ATP is formed during the process of electron transport chain in the mitochondria.<span />
Answer:
The type of disturbance would be that these rivers begin to affect beaver burrows, terrestrial species that live in the surroundings of the rivers since they could drown, flood nearby areas and form new accumulations of water that modify the flora and fauna of certain areas, arrazar with trees or plants that are typical of the place and also generate an increase in volume to the flow that finally end up being the seas, generating that they grow more on the coasts and there is more risk of tsunamis or floods in the cities.
Explanation:
The fluvial dynamics is the process by which the action of the rivers (erosion and sedimentation, mainly) changes in some way the land relief and the layout of the rivers (since new routes are assembled).
It is a fundamental concept in the analysis of hydrography and hydrology, especially in the study of inland waters. Its importance derives from the important consequences that the processes involved in river waters have in the planning of basins and in the construction of infrastructure works, both hydraulic and otherwise.
