Phosphorus is not abundant in the atmosphere. It comes mostly from the land and ocean. Phosphorus cycle through the lithosphere, hydrosphere, and biosphere, but not the atmosphere. The reason for this is that phosphorus cannot be found in the gas state, unlike the sulfur. On the other hand, sulfur cycle partially occurs in the atmosphere.
What is DNA polymerase
It is thought that President Abraham Lincoln suffered from a genetic disorder known as Marfan syndrome. Which types of fibers are affected in this disorder?
The genetic disorder affects the elastic fibre that is made of elastic microfibril, which is an important part of the connective tissue. These fibres are responsible for strength, support and elasticity of vital parts of the body such as heart valves, tendons, blood vessels etc.
This genetic disorder which is inherited is characterized by the loss of strength of the connective tissue when the formation of elastic fiber is affected. This abnormal chemical makeup causes the Marfan syndrome, which affects the eyes, skin, bones, nervous system and the heart.

A school-aged child with cystic fibrosis has been admitted with a respiratory infection. The child has been very disruptive and angry with staff and parents. What does the nurse suspect is the reason for the child’s uncooperative behavior?
Which occurs during translation? A.mRNA is created by using a DNA template. B.mRNA codons are joined by tRNA anticodons to assemble amino acids to form a protein. C.Protein is formed when a polypeptide chain is broken apart and released from ribosome. D.One strand of DNA is copied into a strand of rRNA.
The Answer is B
mRNA codons are joined by tRNA anticodons to assemble amino acids to form a protein.
What did Rudolf Virchow contribute to the cell theory
Rudolf Virchow was a biologist that is known as "the father of modern pathology." He played an important role in postulating cell theory. He concluded that cell arises from pre-existing cells.What is cell theory?
Cell theory was proposed by Robert Hooke, Rudolf Virchow, and others. It stated cells are the structural and functional unit of living beings that comes from other cells that existed previously. The parent cell contains the genetic material that passes on to the next cell.
The division of the cell and its genetic material during division results in new cells from pre-existing cells that have some resemblance and characteristics to the parent cells. The fundamentals proposed by Virchow led to the classification of disease at the cellular level.
Therefore, Virchow concluded about the origination of cells from pre-existing cells.

He concluded that all cells come from preexisting cells.
got it right on edge test :)
What is a advantage of using pluripotent cells instead of multi potent cells in medical treatment
Pluripotent cells can differentiate into almost any type of cell
PLEASE HELP PLEASE!!!!!!! The inheritance pattern of a disorder is illustrated in the pedigree chart. What type of genetic disorder is this? A) codominant B) autosomal recessive C) sex-linked recessive D) incomplete dominance
Since only males are affected, this indicates that the disorder is sex-linked and it is recessive.
