Answer:
The plate will continue to move apart and the distance between two opposite sides will continue to increase very slowly.
Explanation:
The theory of plate tectonic also talks about how divergent boundaries occur. Divergence boundary usually occur between continental-continental plate or oceanic-oceanic plate.
According to the theory of plate tectonic, the opposite sides in a divergent boundary will continue to move apart from each other. The moving apart from each other creates a room for the introduction of molten magma to the surface of the earth. This magma after exposure to the earth surface, solidifies to form a new crust. The magma can be introduce through the mid oceanic ridge . Closer to the mid oceanic ridge much younger rocks are formed . As one move farther way from the mid oceanic ridges the rocks become older.
Generally, between two continents of opposite side the continents will continue moving apart from each other and the distance between them will continue to increase creating a space for magma to migrate to the surface of the earth . New crust are formed in the process.
The picture above illustrate diverging boundary with the mid oceanic ridges.

In this question, one parent is homozygous recessive (bbee) and other parent is dihybrid (BbEe)
B - black fur dominant trait
b - white fur recessive
E- black eyes dominant
e - red eyes recessive
a punnett square shows all the possible combinations of genotypes with the corresponding phenotypes that the offspring could inherit.
the genotypes and their phenotypes for the offspring are given below ;
BBEE / BbEe / BbEE / BBEe - black fur and black eyes
Bbee / BBee - black fur and red eyes
bbee - white fur and red eyes
bbEe / bbEE - white fur and black eyes
after analysing the punnett square the following results are obtained;
black fur and black eyes - BbEe- 4/16
black fur and red eyes -Bbee - 4/16
white fur and black eyes - bbEe - 4/16
white fur and red eyes -bbee - 4/16

Answer:
Option-A
Explanation:
A bacteria divides by binary fission which divides a parent bacteria into the two daughter cells and generation time refers to the average time difference between two consecutive generations.
The bacterial cell grows by the exponential function that is by x initial population of bacteria.
In the given question,
<u>Initial population</u>
the initial population of bacteria - 2x 10³ per ml
So per liter, the bacterial population will be 2 x 10 ⁶
<u>Generation time</u>
1 generation time of bacteria is 30 min.
so 5 hours will have- <u> </u>= 10 generations
<u>New bacterial population</u>
Using formula<u> </u> x initial population of bacteria
x (2 x 10⁶)
= 1048 x (2 x 10⁶)
2048 x 10⁶
Thus, Option-A is the correct answer.
