Evolution is incredibly slow because:
- Changes can only occur in each successive generation
- Helpful mutations occur only rarely
- Situations where different adaptations are necessary are rare

What are three main ways that variations in genotype arise in population?
Variations occur due to mutations. There are three factors of mutations which impact the formation of new genotypes. 1) Point Mutations - Very small impact mutation which still might enhance the protection against environment and reproduction. 2) Mutations that alter Gene number and sequence - has major role in evolution as it might help to add new functions. 3) Mutation Rates - In animals and plants mostly very slow, however, prokaryotes due to high rate are able to mutate very fast.
Factors that slow down the rate of photosynthesis are sunlight and warm temperatures?
Yes, factors that slow down the rate of photosynthesis are sunlight and warm temperatures.
One advantage of a a fever is that it can slow down the?
Fever can slow down growth rate of pathogens
Does diffusion occur slow or fast?
Gases, Liquids, and then Solids.
Do koalas sleep all day?
Koalas are nocturnal animals, which means they are more active at night. Koalas have a slow metabolic rate which is required for them to digest the eucalyptus leaves on which they feed. Eucalyptus leaves are very fibrous and rather low in nutrition, so the fact that the koala has a slow metabolic rate means it can keep the food within its digestive system for as long as possible in order to maximise the energy that can be extracted from the leaves. This slow metabolic rate also means the koalas sleep for more time each day in order to conserve energy.
How does slow change over time occur genetically?
Through mutations in DNA, and natural selection of advantageous mutations.
The hypothesis that the evolution of different species occur at a slow constant rate is called?
Gradualism.

Will rusting occur in boiled water?
Rusting will occur in boiled water but at a very slow rate. This is mainly due to the fact that water which is boiled is said to be de-ionized.
Does a slow loris have a tail?
Some do. Like, genetic mutations er something.
Did the migration of the first Americans occur quick or slow?
SLow
Why is the rate of onset of the medication in intramuscular administration slow?
There is little blood flow to the fatty tissue where the solution is injected. The absorption rate will hence be slow and this will lead to a slow rate of onset.
What is the result of parasympathetic stimulation of the SA node?
Action potentials will occur less often due to an increase in the membranes permeability to K+
Do depressants slow down your heart rate?
You shouldn't be doing drugs and yes, they do slow down your heart rate.
What drugs might cause a slow heart rate would Tramadol or Pregabalin cause a slow heart rate?
There are many drugs which may cause a slow heart rate. Tramadol only causes a slow heart rate if it has been taken excessively, while pregabalin is known to cause only increased heart rate.
What medical term means abnormally slow heart rate?
No, that would be called tachycardia. Bradycardia is an abnormally slow heartbeat.
