Answer:
D. habitat preference
Explanation:
Habitat preference is one of the driving forces for ecological speciation that does not allow interbreeding between the members of a species. In habitat preference, some members of a species have a different preference for habitat than the others. They live in different habitats and do not interbreed. Over generations, these two populations of a species living in different habitats develop genetic variations and interbreed with the members of their own populations only. Gradually, these two populations would develop reproductive isolation and would evolve as two different species.
Answer:
Cells are so little, so they can maximize their ratio of surface area to volume.
Explanation:
Smaller cells have a higher ratio which allows more molecules and ions to move across the cell membrane per unit of cytoplasmic volume. Cells are so small because they need to be able to get the nutrients in and the waste out quickly.
Velocity is the speed of an object moving in a definite direction. The velocity of an object can be uniform or variable. When an object moving along a straight line at variable speed, we can Express the magnitude of its rate of motion in terms of average velocity.
Average velocity=Initial velocity+Final velocity/2
The SI unit of velocity is m/s.
