3.A tendon serves to move the bone or structure.A ligament usually serves to hold structures together and keep them stable.
4.Collagen s responsible for skin strength and elasticity, and its degradation leads to wrinkles that accompany aging.
Answer:
The best estimate of population density of this particular Octopus spieces is (TOTAL POPULATION OF THE OCTOPUS)/(TOTAL AREA OF LAND)
Population density = (15/6) Octopus per hectare
Explanation:
To estimate the population density of a spiece in a particular area of land, we count the total number of the specie in the area and divide the total number by the area of the sampling region.
Above, the marine ecologist counts the number of octopus in three different intertidal regions that are each two hectares. The octopus counts are 7, 2, and 6 respectively.
Therefore, the total number of Octopus is 7 + 2 + 6 making 15. The regions are 2 hectares each. Since there are three of the intertidal regions, the total area is 2 x 3(6 hectares).
Therefore, Population density = (15/6) Octopus per hectare
