In mitosis, division occurs once leading to the production of two daughters cells.crossing over does not occur in the chromosome, so the daughter cells are genetically identical to the parent cell.

In meiosis,cell division occurs twice ,(meiosis I & II),leading to the production of four daughter cells.

Crossing over occurs,leading to genetic variation in the daughter cells.

romanna [79]

Answer:

Density is nearly 3 cabs per hectare

Explanation:

Given -

There are three three intertidal regions.

Area of each intertidal region is 2 hectares.

Number of crab in the intertidal regions are as follows -

Intertidal region I - 7

Intertidal region I - 2

Intertidal region I - 6

Sum of crabs in all three regions is equal to

7 + 2+ 6\\= 15

Total area of all three intertidal regions is equal to

2 + 2+ 2\\= 6 hectares

Now density per hectare is equal to total population of crab divided by total area of all the three intertidal regions

Density = \frac{15}{6} \\= 2.5

Density is nearly 3 cabs per hectare
