Bow 4 - Natural selection

                                                                    BOW 4 - Natural Selection

Natural selection is the gradual, nonrandom process by which biological traits become either more or less common in a population as a function of differential reproduction of their bearers. It is a key mechanism of evolution. Natural selection acts on the phenotype, or the observable characteristics of an organism, but the genetic (heritable) basis of any phenotype that gives a reproductive advantage will become more common in a population (see allele frequency). Over time, this process can result in populations that specialize for particular ecological niches and may eventually result in the emergence of new species. In other words, natural selection is an important process (though not the only process) by which evolution takes place within a population of organisms. As opposed to artificial selection, in which humans favor specific traits, in natural selection the environment acts as a sieve through which only certain variations can pass. Natural selection occurs through the mutation and recombination actions on the genome of the organism, whether through its plasmids or itself. Bare in mind that genotype, the combination of alleles of the genome, affects the phenotype, the physical appearance as a result of the genotype. Therefore, because natural selection initially occurs through the changes in the genome, natural selection acts on genotypes which may or may not have visible phenotypes. Exaptation, cooption, and preadaptation are related terms referring to shifts in the function of a trait during evolution.

                                                               BOW 3 - Ethic of Cloning
                                    If a clone originates from an existing person. who is the parent?     
When theirs a clone there is no parents only the surrogate mother, she is only the birth mother. The clone
was placed inside of her, for her to give birth. The organism who's DNA was replicated to create the clone,
is the parent. Just an exact copy.

                               What are some of the social challenges a cloned child might face?
Some social challenges a cloned child might have is that people expect them to be exactly like the person who has the same DNA as the clone. Also the clone can be at risk to experience some abnormalities. 

BOW 2 - Mutations

Sense - It is sometimes seen with a single substitution mutation, when the change in DNA base sequence, 

the new codon is still coding for the same amino acid.

NON Sense - this occurs when a new nucleotide into a stop codon  and the protein stops prematurely.

Deletion - loss of dexyribonucleotide during replication.

Insertion - when extra base pairs are inserted into the DNA.

Frame shift - the deletion of a letter , the entire sequence shifts to make a three letter codon.

                                      
               Point Mutation - This is the simplest mutation, when one letter is switched with another.

              Translocation - A lethal mutation, 1/2 homologous chromosomes bind to each other.
                               

 

This is a food web pattern. The producers are the pine trees and oak acorns, And they are eaten by the primary consumers. The primary consumers are the Pine borer, the Mouse, and the salamander, and this group of organisms are eaten by the secondary consumers. Secondary consumers are the the snakes, the golden crowned-king let, and the red-tailed hawk.     

                                                                                                                                                                               

How the structure of macromolecules affects their function

Most macromolecules acquire their function by interacting other macromolecules.
Macromolecules work similar to locks and keys, without the right fit it cannot interact

with its intended target and loses its function.
