Answer:the answer is B and C since there is no soil or life
Explanation: explanation is up there
Answer:
Cones
Explanation:
Gymnosperms are a group of plants known as spermatophyta i.e. seed plants. Gymnosperms are named after the fact that they bear naked seeds. Their ovule, instead of being enclosed in ovaries as in Angiosperms, are located on sporophylls (leaf-like structure bearing the sporangia), which collectively makes up the CONES.
The bearing of naked seeds on cones by Gymnosperms distinguishes them from the other group of spermatophyta, Angiosperms.
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).
Any broad spectrum antibiotics can be used against bacterial infection, but beta-lactams like penicillin, amoxicillin and cephalosporin as well as macrolides are more effective againts gram-positive bacteria.
