Answer:
Density is nearly 3 cabs per hectare
Explanation:
Given -
There are three three intertidal regions.
Area of each intertidal region is 
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
Total area of all three intertidal regions is equal to
hectares
Now density per hectare is equal to total population of crab divided by total area of all the three intertidal regions
Density 
Density is nearly 3 cabs per hectare

Answer:
homologous
Explanation:
<em>Since the front legs of a cat and the arms of a human share a bone structure that suggests a common lineage, these structures are said to be homologous.</em>
Homologous organs are organs that share some similarities in different organisms but whose function differ in these organisms.
The organs are structurally similar but functionally different. Homologous organs represent one of the evidences scientists use to support evolution.
The front legs of cats and the arms of humans are functionally different, even though their structure is based on the same five digit plan.
