Variation – Chapter 19

Today in Biology , Ceci gave us the task of answering the following questions, I worked with Renata Marty.

19.1 ) Decide wether each of these features shows continuous variation or discontinuous variation.

a)  Blood group in humans / discontinuous variation

b) Foot size in humans  / Continuous variation

c) Leaf lenght in a species of tree /  Continuous variation

d) Presence of horns in a cattle / Discontinuous variation

19.3 ) The photograph shows a small mammal called a tarsier. Tarsiers feed on insects, which they hunt at night.

How is the tarsier adapted for survival environment?

First of all, as his skin colour is somehow similar to the color of the trees, he can easily camuflage and so he can not be seen by predators. Secondly, his hands are perfect to climb trees, as he has 4 legs and his fingers perfectly match each other.
