Answer:
cell walls made of chitin
Explanation:
Fungal cells differ from mammalian cells in that they have cell walls that are composed of chitin, glucans, mannans, and glycoproteins. Both mammalian and fungal cells have cell membranes; however, they differ in their lipid composition.
Galapagos islands are groups of island in the pacific ocean that are known to have a wide range of native animals such as giant tortoise that found no where else on earth. These native animals helped Darwin in the development of the theory of natural significance which attributes to the biological significance of the Galapagos islands. Human species is a threat to the natural wildlife on these islands mainly due to poaching and destruction of natural forests that destroys habitat and also impacts negatively on biological diversity of living organisms.

Explanation:
Answer:
smelling rotten eggs - covering your nose
touching a hot dish - pulling your hand away
jumping into a cold pool - shivering
Explanation:
<u>A stimulus generally refers to a detectable change in the environment of an organism. These changes could be physical or chemical and could be in the internal or external environment of organisms. </u>
Organisms react to changes in their internal or external environment by responding appropriately. Hence perceiving the smell of rotten egg, feeling the hotness of a dish by touching it, and feeling cold immediately one jumps into a cold pool are all examples of stimuli and their corresponding responses would be covering one's nose, pulling the hand away, and shivering of the body in order to counter the cold.
In other words:
<em>smelling rotten eggs - covering your nose</em>
<em>touching a hot dish - pulling your hand away</em>
<em>jumping into a cold pool - shivering</em>
Answer:
An example of a scientific investigation design that uses independent variable and dependent variable in its design is a research that seek to find out the effect of two different fertilizers on the growth of a tuber crop (yam). The independent variable in this case is the type of fertilizer used while the dependent variable is the corresponding growth of the tuber crop. In a research set up, the independent variable is the variable that cause a change in the dependent variable.
