Answer:
Evolution.
Explanation:
The ground finch could not survive after the drought with the size of its beak.
The beak required in order to feed on the hard seeds needed to be stronger and longer.
Due to this, the finch beak <em>evolved and developed into a stronger longer beak</em> adapted to feeding on large hard seeds.
Without this evolution, all the finches left on the Galapagos island could face <em>extinction out of starvation.</em>
Diffusion is the movement of particles across a semi-permeable membrane from a lower concentration to a higher concentration
Answer:
The one cell of a unicellular organism must be able to perform all the functions necessary for life. These functions include metabolism, homeostasis and reproduction. Specifically, these single cells must transport materials, obtain and use energy, dispose of wastes, and continuously respond to their environment.
Small Geographic Range
“A useful index fossil must be distinctive or easily recognizable, abundant, and have a wide geographic distribution and a short range through time.”
The fragment and plasmid are both cut with the same restriction enzyme is the that help ensure that a new piece of DNA can be inserted inside a bacterial plasmid when the two are mixed together.
Explanation:
The gene cloning requires one of the necessary step of forming chimera in which gene or DNA sequence of interest in inserted into the plasmid of bacteria.
The gene of interest and plasmid is cut by using same endonuclease enzymes.
The endonuclease used are same because they produce fragments having same complementary ends which bond to form chimera or recombinant DNA.
The overhangs produced by endonuclease lets the gene and plasmid form base pair with each other.
If overhangs are not there DNA ligase performs the function of sealing the plasmid and gene.
