Enzymes involved in the breakdown of fats contribute to the reaction in which way? These enzymes - O eliminate toxins produced by the reaction.
O increase the speed of the reaction.
O are completely consumed during the reaction.
O reduce the reactants needed for the reaction.

...enzymes increase the speed of the reaction

Explanation:

In biological systems, enzymes are proteins that mediate chemical reactions. They increase the rate of chemical reactions, by lowering the activation energy, required for the reaction (eg. hydrolysing a bond) to occur.

Enzymes require the aid of cofactors, inorganic molecules to act as complements to enzymes. They cause structural changes that result in substrate recognition and binding. Here they act by breaking down large fat molecules into fatty acids and lipids.

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.

passive transport is a movement of biochemicals and other atomic or molecular substances across cell membranes without need of energy input. unlike active transport, it does not require an input of cellular energy because it is instead driven by the tendency of the system to grow in entropy.

so, according to what that says, i believe it's hypertonic and hypotonic.

good luck!
