Plate tectonic processes such as the redistribution of continents, growth of mountain ranges, formation of land bridges, and opening and closing of oceans provide a continuous but moderate environmental pressure that stimulates populations to adapt and evolve.
Answer:The Monerans are unicellular organisms. They contain 70S ribosomes. The DNA is naked and is not bound by a nuclear membrane. It lacks organelles like mitochondria, lysosomes, plastids, Golgi bodies, endoplasmic reticulum, centrosome, etc.
Explanation:
Answer:
An aneurysm is an excessive localized enlargement of the artery caused by the weakening of the arterial walls. Angioplasty is an incorrect treatment for aneurysm because this would worsen the condition and can lead to death if the aneurysm bursts due to the pressure applied by the widening of the arteries.
Explanation:
Answer:
<u>C. The coastlines of South America and Africa were similar in shape, suggesting that they shared a common tectonic plate.</u>
Explanation:
- As suggested by the Alfred Wegener, the plates of the South America and the African plants had a similar geologic history and thus shared a common tectonic boundary and hence validate the proof of the superclass and the drifting of the plates at various time zones.
- Thus after the 1960s the plate tectonic theory came into the limelight and was heavily recognized to be fit the works of the drifting of the continental landmasses.
A) ability to learn or acquire the new traits
Explanation:
It's the process that species go through in order to become accustomed to an environment.
