Answer:

<h2>(A) Protein x normally stimulates cell division.</h2><h2 />

Explanation:

Protein who stimulates cell division are known as proto-oncogenes. If there is a mutation in proto-oncogene ,then this gene is converted into oncogene which causes cancer. Here protein x ( proto-oncogenes) normally stimulates cell division, if new mutation occurs in this gene, then this gene is converted into oncogene and resulted in the formation of cancer.

Vinil7 [7]

Answer:

D. The system provided an organized way to classify living things and it has been able to grow and develop. There is a place to enter new organisms as they are discovered or new evidence occurs

Explanation:

Carolus Linnaeus is a Swedish Botanist is universally referred to as the FATHER OF TAXONOMY because of his contribution to the development of a system of naming and classifying species, which is still globally recognized today. Linnaeus proposed the binomial nomenclature system which uses two of the hierarchical classification to name organisms i.e. genus and species. For example, humans are Homo sapiens; Homo (generic name), Sapien (specific name).

Modern scientists later modified Linnaeus classification by adding new ranks in order to accommodate new species and removing incorrectly classified organisms but Linnaeus classification remains the foundation. One important modification was the inclusion of a new taxon called DOMAIN.

kirill [66]

Answer:

<h2>A site for the exit of the diphosphates removed from the nucleotide triphosphates.</h2>

Explanation:

Transcription occurs in three steps, i) initiation, ii) elongation, and iii) termination.

Elongation: during elongation , the RNA polymerase add new nucleotides in the growing chain of RNA molecule until it encounter terminator factor, or until it terminate transcription.  RNA polymerase has three prominent channels, i) channel for entry of DNA template strand, ii) channel for exit of DNA strand  and iii) channel for exit of newly synthesized RNA molecule. There are lots of other enzymes which helps in transcription.
