A. because you can't observe an animal in its natural habitat if you take it out of its habitat or if you have a model.
Prominent sea-level changes and climate fluctuations occurred during the past 103-105 years. Sea level changes strongly influence river behaviour and coastal development. Climate changes affect the discharge and sediment load characteristics of rivers and also the development of a protective vegetation cover that stabilises the landscape. Changes in sea level and/or climate induce changes in river type, channel pattern and sediment sequences. Climate changes during the (recent) Quaternary had a particularly strong impact. In (now) temperate regions, glacial climate was much drier and colder than today. Wet-tropical areas were drier as well. A belt of permafrost surrounded the large continental ice sheets and sea levels were some 120 m and perhaps even 135 m lower than today. There are strong indications that mass wasting processes such as frost weathering<span> and </span>`gelifluction'<span> in high-relief areas were more prominent than today and that consequently the sediment loads of rivers were greater than at present. Once most of the Pleistocene ice cover had disappeared, some 6,000 years ago, the rate of sea level rise decreased and coasts adapted to the higher sea level. Today, (Pleistocene) glaciers that have long disappeared still influence some 15 percent of the land surface. It is impossible to understand the complexity of `landforms in lowlands' without referring to their present climate </span>and<span> their climatic history.</span>
Answer:
Option a
Explanation:
A eukaroytic cell contains more organelles than prokaryotic cells, and it is much bigger and complex.
hope this helps and is right :)
Answer:
Commiphora africana, &
Commiphora angolensis
Explanation:
This is because they share the same genus names. Taxonomists use classification in biology to show the relationship between organisms. Species is the lowest rank while genus is just one rank above. Binomial nomenclature used Genus and Specie name in naming organisms.
This means that Commiphora africana, &Commiphora angolensis are closely related because they share the same genus name. They are like horses and donkeys than can interbreed but will not produce fertile offspring because they are still different species.
