Answer:
This means that the two separate rocks were once part of one piece of rock. These layers got separated most probably by continental drift as a result of tectonic plate movements. An example of such a fossil is the Mesosaurus, a freshwater crocodile-like reptile, that is found in Southern Africa and Eastern South America continents- that means they were once one land mass.
The environment in these two separate layers would most likely be different. As the layers drift apart from each other , they drift across latitudes that are determinants of climate in a region. Therefore, even the organisms in these two rock layers will evolve differently (even though they will share a common ancestor) in adaptation to respective environments – this is called allopatric speciation.
TT or Tt because even though the second letter is not dominant the first one is greater
Answer:
option B
Rough endoplasmic reticulum → Golgi apparatus → plasma membrane
Explanation:
The pathway used to make and export proteins from the cell is rough endoplasmic reticulum which have ribosomes. After which it is transferred to golgi apparatus. The golgi apparatus process it and form vesicle. These vesicles are then transported to plasma membrane.
Answer:
The correct answer is b) "All of the above".
Explanation:
Nowadays it is known that the lipid bilayer of the cells is not static, actually, the modern Fluid-Mosaic membrane model establishes that the lipids move constantly within the lipid bilayer. The lipids are able to rotate within its axis, the lipids are able to movement laterally moving from one site to the other within the same plane, and also can move from a plane to the other plane in what is known as transverse "flip flop" movement.
