Answer:
Protists are a diverse collection of organisms that do not fit into animal, plant, bacteria or fungi groups. While exceptions exist, they are primarily microscopic and made up of a single cell (unicellular), according to the educational website CK-12.
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.

Answer:
DDT was once considered a "silver bullet" that would permanently eradicate insect pests. Instead, DDT is largely useless against many insects. Which of these would have prevented this evolution of DDT resistance in insect pests?
What would have prevented the evolution of DDT resistance in insect pests is the None of the insect pests would have genetic variations that resulted in DDT resistance.
Explanation:
Answer: Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. These cells are our sex cells – sperm in males, eggs in females. ... These four daughter cells only have half the number of chromosomes? of the parent cell – they are haploid.
