Removes the nucleus from an egg cell and replaces it with the nucleus from another organism
Bright colors such as flowers or light green bushes/trees would result in an decrease in a blackbirds population because the blackbird wouldn't be able to blend into its environment due to the dark color it has, allowing many predators to spot it. So brighter colored environments would result in the decrease of the blackbird population.
The lipids form an insoluble barrier.
Phospholipids, a type of lipids, don’t dissolve in water. Membrane-forming lipids have like other lipids hydrophobic region, but also in addition, they have hydrophilic region. In the cell membrane, they are organized in a lipid bilayer. In each layer, hydrophilic heads face a solution, and hydrophobic tails are inside the layer. That way, phospholipids are in contact with water, but still present a barrier because of their hydrophobic tails inside the layer.
Answer:
In genetics, a promoter is a sequence of DNA to which proteins bind that initiate transcription of a single RNA from the DNA downstream of it. This RNA may encode a protein, or can have a function in and of itself, such as tRNA, mRNA, or rRNA. Transfer ribonucleic acid (tRNA) is a type of RNA molecule that helps decode a messenger RNA (mRNA) sequence into a protein. tRNAs function at specific sites in the ribosome during translation, which is a process that synthesizes a protein from an mRNA molecule. Proteins are built from smaller units called. An exon is the portion of a gene that codes for amino acids. In the cells of plants and animals, most gene sequences are broken up by one or more DNA sequences called introns.
Answer: semi-permeable
Explanation: Dialysis tubing, also known as Visking tubing, is an artificial semi-permeable membrane tubing used in separation techniques, that facilitates the flow of tiny molecules in solution based on differential diffusion.
