Answer:
I think it is B. The Genes that a person has
Explanation:
Please Correct me If I am wrong :)
the process by which the structure of a biological community evolves over time. Two different types of succession—primary and secondary—have been distinguished. Primary succession occurs in essentially lifeless areas—regions in which the soil is incapable of sustaining life as a result of such factors as lava flows, newly formed sand dunes, or rocks left from a retreating glacier. Secondary succession occurs in areas where a community that previously existed has been removed; it is typified by smaller-scale disturbances that do not eliminate all life and nutrients from the environment.
The answer is D. Phospholipids are diglycerides (two fatty acid chains covalently bonded to a glycerol molecule)
that are covalently bonded to a phosphate group by an ester linkage. Fatty
acids are long chains that are mostly made up of hydrogen and carbon, while
phosphate groups consist of a phosphorus molecule with four oxygen molecules
attached. Glycerol is a 3 carbon chain containing hydroxyl groups in each of the carbon.
In humans, DNA and RNA carry out various roles. DNA is responsible for genetic information storage and transmission, while RNA specifically codes for amino acids and serves as a protein-making messenger between DNA and ribosomes.
Answer:
3. Polysaccharide carbohydrate
EXPLANATION:
The POLYSACCHARIDE capsule of Streptococcus Pneumoniae is the major virulence factor in it's invasion and subsequent infection.
The capsule helps to avoid phagocytosis which is a defence mechanism by the body.
The polysaccharide capsule also gives the bacterial organism several serotypes.
The pneumococcal vaccine is derived from the organism's capsule.
