Answer:

B

Explanation:

You have three stages for analyzing.

You start at B with a tiny free-swimming larva.

Some of those larvas start making segmentation. It is an evolutionary trait.

This divide what we today know as gastropods and those animals that continue with evolution.

Those segmentation larvas also evolve with a molten external skeleton which made them all crustaceans as we know them today.

Crab and barnacle are differentiation into the crustaceans.

c. the gravitational forces due to the sun and the moon cancel each other's effect

Explanation:

The two diagrams represent Neap tides. Neap tides occur when the Sun, the Moon and the Earth are aligned at right angles. Moderate tides are formed because the bulge due to gravitational pull of the Sun cancels the bulge due to moon. The difference between the high tides and the low tides is the smallest.

There are 1000 micrometres (um) in a millimetre (mm).
Vesna [10]

Answer: The length of the cell in millimetres is 0.0015.

Explanation:

Given conversion :

1000\mu m=1mm

Thus 1\mu m=\frac{1}{1000}mm=0.001mm

Given : Length of the cell = 1.5 micrometers (\mu m)

To find: Length of the cell in milllimeters (mm)

Length of the cell in milllimeters (mm) = 1.5\times 0.001mm=0.0015mm

The length of the cell in millimetres is 0.0015.

In the question given above, the lizard specie has been separated by the formation of a stream which divide the region into two.
2.B.
Allopatric speciation refers to the mode of speciation that occur when biological population of the same specie become isolated from each other to an extent that it interferes with genetic interchange. It usually occur as a result of change in the environment.
