Answer:
The first cause of eutrophication is the increase level of nutrients in water.
Explanation:
Then the other effect follow:
1.- Nutrients promote more phytoplanckton at the surface of the body water.
2.- phytoplancton die and settle down at the bottom.
3.- since in the bottom there is no much more sun, the algae at the bottom start to die, plus the phytoplacton that is falling, the sediment at the bottom start to grow.
4.- Since there is any living thing that can produces oxygen in water( it produces hypoxic conditions), other living things start to die.
The black coat allele will be represented as the capital letter over the lowercase letter in guinea pigs. When crossing, you get 25% for homozygous dominant, 50% for heterozygous dominant, and 25% for homozygous recessive.
Answer:
There are three types of DNA Mutations: base substitutions, deletions and insertions.
Base Substitutions. Single base substitutions are called point mutations, recall the point mutation Glu -----> Val which causes sickle-cell disease.
Deletions. ...
Insertions.
Surface ocean currents form large circularpatterns called gyres. Gyres flowclockwise in Northern Hemisphereoceans and counterclockwise in Southern Hemisphere oceans.
The correct order is: B) 2, 5, 4, 3, 1.
2. A segment of DNA is transcribed in mRNA. mRNA is transferred to the cytoplasm. This is the process of transcription that occurs in the nucleus of the cell and it is the first step of gene expression. It is performed by the enzyme RNA polymerase.
5. The mRNA strand is fed through the ribosome. Ribosome is an organelle where protein synthesis (translation) occurs and it consists of proteins and RNAs.
4. Molecule of tRNA delivers amino acids from to the ribosome. tRNA is transfer RNA because of its function to carry amino acids to the ribosomes during protein synthesis.
3.The amino acids are dropped off at the ribosome.
1. The amino acids are joined to make a protein. Amino acids are added to a growing protein chain.
