Answer:

carbohydrate chain

Explanation:

Cholesterol is more rigid than some of the other lipids in the membrane. Cholesterol keeps the fatty-acid tails of the phospholipids bilayer from sticking together, which contributes to the fluidity of the plasma membrane. The membrane would become rigid. Transport protein move needed substances or waste materials through the plasma membrane . Carbohydrate defines the cell characteristics and help cells identify chemical signals.

If a forest contained mostly light colored trees which type of moth would you expect to be most common
dexar [7]

Answer:

The light speckled moth

Explanation:

<em>Biston betularia</em> or peppered moth is a moth that is very commonly present in Asia, Europe and North America. Normally it occurs in two forms:

1)  A dark morph

2) A light, speckled morph

The peppered moths are a frequent target of birds but they are smart enough to rescue themselves against predator birds by selecting appropriate location for their habitats. For example: If a forest contained mostly light colored trees , light, speckled morphs will be more abundant there because due to a matching color with trees they will be less visible to birds and other predators. Similarly, If a forest contained mostly dark colored trees,dark morphs will be more common so that they rescue themselves due to camouflage from the attack of birds.
