<h3><u>Answer;</u></h3>
The above statement is <u>False </u>
<h3><u>Explanation;</u></h3>
- Speciation is an evolutionary process in which new species arise. There are three types of speciation, namely; sympatric, parapatric and allopatric speciation.
- <em><u>Sympatric speciation is a pattern in which speciation occurs in the absence of a physical barrier to gene flow; ex. polyploidy arising in flowers.</u></em>
- In an Allopatric speciation on the other hand, a physical barrier arises and separates two populations, ending gene flow between them and allowing reproductive isolating mechanisms to evolve so that later if the two groups come back into contact they will no longer be able to reproduce together, therefore making them different species.
The answer to this question is torque. Force times the distance to the pivot for a lever is the torque.
Answers. Sodium/potassium pumps (Na/K ATPase) pump 3 Na out of the cell and 2 K into the cell. Without that, there would be relatively more ions in the cell. Therefore, the cell would swell up from osmosis. However, there is a basal efflux of K, (resting membrane potential), that would eventually equilibrate with the extracellular concentration.
D) is the answer
Hope I helped XD
