<span>Classical conditioning. Classical conditioning occurs when we link something usually considered "neutral" with a what is called an involuntary response. An example of this would be a student who begins to fear school because of a bully at school. The student associates school with the bully. A well known example of classical conditioning is Pavlov's experiment with his dogs, where the dogs learned to associate the ringing of a bell with eating meat. The dogs only had to hear the bell (not actually see the meat) in order to begin salivating in anticipation of being given the meat to eat.</span>
Answer:
She might study the function of putative oncogenes and/or tumor suppressor genes in AML mice by transfecting small interfering RNAs (siRNAs) which are able to suppress the expression of genes of interest through the RNA interference (RNAi) pathway
Explanations:
The RNA interference (RNAi) pathway is a naturally occurring mechanism which is used in molecular biology laboratories to inhibit the expression of target genes. The RNAi technique consists of delivering small interfering double-stranded RNAs (siRNAs, 18-30 nucleotides in length) into the cells in order to inhibit the translation of genes and/or trigger mRNA degradation, thereby suppressing target gene expression. These siRNAs are specifically designed to bind by complementarity to transcripts of target genes (i.e., mRNAs). In this case, the RNAi pathway can be used to study the function of genes involved in AML pathways (e.g., apoptosis, cell proliferation, etc).
It is a two-step process that reduces the chromosome number by half from 46 to 23 to form sperm and egg cells when the sperm and egg cells unite at conception each contributes 23 chromosomes so the resulting embryo will have the usual 46
Answer:
D
It helps the reader to understand which layers of the atmosphere are most important. Don't cheat
I would say C because there are many more types of plants than animals. Plants convert light energy yes.
