Answer:
Options A, B, E, and F are correct
Explanation:
A). In the cell cycle, DNA replication is a process by which a duplicate DNA strand is produced with the help of replication machinery (enzymes, nucleotides, etc.). The overall process ensures that the newly developed strand is free of any mutations (errors) causing the production of wrong proteins at later stages. Although, there are chances of positive, negative or neutral mutations, the replication machinery aims to avoid any such errors at this stage.
B). DNA stores genetic information in the form of codes (known as codon) which needs to be translated in the form of proteins. This process is known as a transcription by which messenger RNA (mRNA) is produced in the nucleolus. Thereon, it is transported outside to encode proteins with the help of ribosomes. The process of copying genetic information on DNA in the form of mRNA is known is transcription.
E). The figure shown is also known as the central dogma of life. According to which, DNA (genetic information) is transcribed into RNA, which is then translated to proteins. In brief, RNA molecules brings the information from nucleous to ribosomes and make proteins. These proteins are often enzymes, hormones, and other biomolecules that perform the important functions in living organisms.
F). DNA and RNA are two types of nucleic acids responsible for all types of life on Earth. Since both of them are well recognized as nucleotides, they are made up of the same genetic building blocks known as nucleotides. Further, each nucleotide is comprised of a five-carbon sugar, a phosphate group, and a nitrogen base. The sequence of these nucleotides is responsible for the production of specific types of proteins.
effect is from the modification of land surfaces. Waste heat generated by energy usage is a secondary contributor.
Epidemiology, population,
The answer to this question would be: paranasal sinus.
There are a few sinuses near the face area. The sinus can be classified based on the bone that makes then to sinus maxillae, ethmoid, sphenoid and frontalis. This structure frequently gets infected causing sinusitis. Sinusitis patient can complain pain or feel the sinus got filled with some liquid.
The answer is splitting of water molecules. This happens during the light stage of photosynthesis where light energy from the sun is absorbed by chlorophyll is used to split water molecules into hydrogen ions and oxygen. This process is called photolysis. The hydrogen ions joins the dark stage or the light independent stage, while oxygen gas is either released to the atmosphere or used for cellular respiration.
