Point A when inhalation begins
Answer: The correct answer is-
Allopatric- option 2.
Sympatric - option 1.
Allopatric and sympatric are primarily the two major mechanisms for speciation ( formation of new species from an ancestral species).
In allopatric speciation, a population splits into two different species when it is isolated by physical or geographical barrier.
On the other hand, sympatric speciation occurs wihtin the same area. A population splits into two species that is becomes reproductively isolated when a change in the chromosome number occurs.
Thus, option first corresponds to sympatric whereas option second shows allopatric speciaton.
Answer:
The walls observed were plant cell walls, that form the tissue.
Explanation:
Hooke's observation resulted in the discovery of the plant cells, which only began possible when the microscope was invented. As a result, Hooke defined the term "cell" to describe the "cavities" visible under the microscope.
The best answer is "foreshocks before the quake and aftershocks after the quake".
These terms are used to characterise the events of an earthquake over time. Foreshocks are small shocks that can occur before the main seismic event. Aftershocks, like foreshocks, are smaller seismic events that can occur after the main seismic event.
Cells are living little parts that their functions are to produce food in a plant or keep alive something, cells also have the ability to replicate.
