There are many human activities that could contribute significantly to the creation of dead zones, and here are some of them:
1. the use of chemical fertilizers
2. urban land use
3. coastal littering, as well as runoff from sewage
4. use of harmful phosphates in detergents
Dead zones are places in waters on Earth where there is so little oxygen left due to pollution that marine life cannot survive there.
The question is incomplete as the options are not provided which are:
RNA replicase is present in the viral capsid.
The RNA genome is of the plus sense and RNA replicase is present in the viral capsid.
The new bacteriophage is a retrovirus.
The RNA genome is of the plus sense.
Answer:
The RNA genome is of the plus sense and RNA replicase is present in the viral capsid.
Explanation:
The bacteriophage is the virus particles which are composed of the genetic material enclosed in the Capsid protein. The Bacteriophage virus infects the bacteria and uses their replication machinery to replicate themselves.
In the given question, all the proteins along with RNA for translation or ribosomes is provided. The single-stranded RNA is first their genome copied by the RNA replicase and the positive strand, therefore, acts as the mRNA. This mRNA is then translated into the protein sequence and a new virion is produced.
Thus, the selected option is correct.
Answer:
Scientists use scientific names for organisms so that it is universally understood what organism they are referring to. What is the advantage of using scientific names instead of common name? This naming is essential for the classification and organization of organisms which makes the study of an organism easier and understandable.
Answer:
c) Both are functions of blood, that is, to carry oxygen to the cells and also remove wastes from the body.
Explanation:
Blood is a form of connective tissue and is made up of red blood cells, white blood cells, platelets and blood plasma. The red blood cells contains a metallo-protein structure known as hemoglobin. This hemoglobin binds to the oxygen and carry them to the cells and the tissues for proper functioning of them. The waste products like carbon dioxide is carried by the blood from the body tissues to expel it out from the body.
