Things such as coal and oil are limited because they are only found in some places
Distribution of phenotypes within a population may be impacted by different types of natural selection. These types of selection include;
Directional selection involves a change in the environment shifts of phenotypes observed. Example is the giraffe neck-length, where the length got longer and longer over time to reach the leaves at the top of trees.
Stabilizing selection , this is a selection where an average phenotype is favored. example is number of eggs laid by birds such that too many eggs will be a waste of energy because some chicks would starve.
Disruptive selection is a selection where individuals with an average value of a trait are affected most while those with values below average are affected least. Example small individuals are capable of hiding from predators while big individuals can not fit in the hiding place but instead will fight with predators.
I believe the correct answer is true. A species accumulation curve can be used as a tool to approximate local, or alpha, diversity. The shape of this curve depends largely on the order of the samples processed. Hope this answers the question.
This would be an example of:
C) an insertion mutation.
Notice how the sequence contains the same letters as before, only an A is added to the beginning. Adding extra nucleotides is an example of an insertion mutation, a type of frame-shift also, because the reading frame will be thrown off downstream.
The cell grows, makes a copy of its DNA, and prepares to divide into 2 cells.
Or for APEX---->The chromosomes are duplicated or the cells prepare for mitosis
The cell prepares for mitosis.
