answer : proteins and lipids
Plants are producers and make their own food through a process of photosynthesis.
Organisms are classified into domains according to shared characteristics.
Answer: D. B and C
Pasteurization
Aseptic packaging
Explanation:
Pasteurization and aseptic packaging are the two methods that can be used for the preservation of food and requires the process of heat for providing sterilization or protection against the microbes.
Pasteurization is a process in which the food item is treated with a mild heat of approximately less than 100° C so as to kill the microbes present in the food and increase the shelf life of the food.
In aseptic packaging the raw and unprocessed food is sterilized by heating at high temperatures for a particular amount of time and then further cooled and delivered inside a packaging unit.
Answer:
DNA:
- is a single molecule that can be over 10,000,000 nucleotides long
- is usually double stranded
- includes the base thymine
- is the genome for prokaryotic organisms
RNA:
- can be translated into a protein
- is usually single stranded
- includes ribose sugar
- is a single molecule that can form a complex secondary structure
Explanation:
Deoxyribonucleic acid (DNA) is the hereditary genetic material of both prokaryotic and eukaryotic organisms, while RNA is the genetic material of many viruses. DNA is a double helix molecule composed of four types of nucleotides: a nitrogenous base (Adenine, Thymine, Cytosine and Guanine), a five-carbon sugar (i.e., deoxyribose), and a phosphate group. On the other hand, RNA is usually a single-stranded molecule whose nucleotides contain ribose sugars and Uracil bases replace Thymine bases. During translation, a type of RNA molecule referred to as messenger RNA (mRNA) is used as template to direct the synthesis of a polypeptide chain (protein). This RNA molecule can fold to form stable double-stranded RNA hairpins (i.e., secondary structures).
