xons are coding areas whereas introns are non-coding areas. ... An exon is termed as a nucleic acid sequence which is represented in the RNA molecule. Introns, on the other hand, are termed as nucleotide sequences seen within the genes which are removed through RNA splicing for generating a mature RNA molecule
Answer:
<u>Option-(D):</u>T cells attack antigens on foreign substances and B cells produce antibodies.
Explanation:
- The defense mechanism or we can say the immune system is divided into many layers of cells, as the primary protection for the human body is the integumentary system or simply skin and the rest of the defense lines follow up. As, there is a proper channel for the different molecules to pass through the body, while the pathogens or those hazardous molecules which are required to be removed are identified with the help of the B-cells and the T-cells kill or eliminates them to avoid any further damage to the human body.
- However, both of the cells are termed to be related to the interstitial spaces inside the human body, which is also called as the lymph and the cells are called as lymphocytes.
The surrounding tissue cannot receive oxygen and they begin to die.
Answer:
Generally the primary organic molecules in cells which support the metabolic and biochemical process of the cells are bio molecules Theses are Carbohydrate
Protein
Lipids
and Nucleic acids of DNA and RNA. They can also be the minute hormones and metabolites present in the cells.
Generally, CHO provide structural supports to the cells,and acts as sources of energy.
Protein forms most enzymes for biochemical reactions,and aids movements, through muscle contractions. Besides,muscles are made of protein.Therefore protein forms the structural basis of the muscles.This aids movement and locomotion for support.
Lipids are the richest source of energy for the cell,and provides support the cells membrane.
The nucleic acids,are primary concerned with the transfer of inheritable characteristic from mother cells to the daughters during reproduction.While the DNA is the genetic information been transferred,the RNA is the vehicle for transmission of the genetic information as protein from the parents' nucleus to the offspring. Thus the nucleic acid roles it for transmission of genetic information as genes,(DNA) and translation of these genes as proteins(RNA).Hence,Nucleic acids does not participate in the cells' support.
Therefore
Explanation:
The discovery should be first published in a journal to be reviewed by other scientists to ensure that it is correct/repeatable. After this, the discovery would most probably be reported in scientific magazines and then in newspapers, important discoveries would probably be reported by newspaper quickly though which leaves the potential for a discovery to be untested and incorrect.
