Answer:
By transfecting small activating RNAs
Explanation:
Small activating RNAs (saRNAs) are an emerging class of non-coding RNAs (ncRNAs) that are capable of activating gene expression at transcriptional level. The saRNAs are small double-stranded RNAs (dsRNAs) that bind to promoter sequences in order to activate the expression of target genes. These molecules are structurally similar to small interfering RNAs (siRNAs), i.e., they also have a size of 21 nucleotides and two overhang nucleotides at the 3' end of both strands.
Answer:
scientific conclusions are reliable as they are helpful for many things however it is true that after the evolution of new ideas the old theory have some changes or may change fully or may be proved wrong but yeah the old theories are still helpful for many reasons and things.
so I think scientific conclusions are reliable
Answer:
e) unicellular, colonial, or multicellular.
Explanation:
Protists originates from the Kingdom Protoctista. They comprise of organisms that are unicellular (Amoeba) or unicellular-colonial (volvox) in nature and which have no tisssues, therefore they are at the cellular level of organization.
Examples include, Amoeba, Paramecium, Euglena, Slime mold, Kelp, Diatoms, DInoflagellates. etc.
Some of them are also considered to be multicellular eukaryotes e.g slime molds, red algae etc. Eukaryotic organisms are organisms that possess cells containing a nucleus.
Characteristics in which protists exhibit varies from one species to the other.
For example, the mode of nutrition in eukaryotic algae are autotrophic in nature, in amoeba, they are gifted with pseudopods(false feets) in which they used to engulf prey(a term known as phagocytosis) therefore making them to be heterotrophic in nature.
In protist, locomotion varies from one organism to another. For example, in Amoeba , locomotion is achieved by extending and retracting pseudopods, Euglena are flagellated in nature , hence they move with the flagella. In Paramecium that are ciliated in nature, they move by propelling their cilia. etc.

Answer:
1, 2, and 5
Explanation:
Viruses are pathogenic microorganisms that lack the ability to thrive and reproduce outside of a living host cell. Their structure is simple - they consist of a nucleic acid molecule surrounded by a protein coating and sometimes an outer envelope. They are too small to be seen by a light microscope.
As they are way smaller than living cells, viruses are smaller than organelles as well. They don't have their own metabolism. Their reproduction is not based on division. They don't have any organelles, including the cytoplasm. They are surrounded by a protein coat called the capsid.
Based on this information, we can see that the correct statements are statements 1, 2, and 5.
