A linear plasmid contains only two genes, which are 2 transcribed in opposite directions, each one from the end, toward the center of the plasmid. Draw diagrams of: a. the plasmid DNA, showing the 5' and 3' ends of the nucleotide strands.
b. the template strand for each gene.
c. the positions of the transcription-initiation sites.
d. the transcripts, showing the 5' and 3' ends.

The pattern of this wave changes between its beginning and end. what is true about the amplitude and wavelength of the wave when the pattern changes?

What initially causes a nerve impulse? release of enzymes out of the neuron movement of chemicals into the dendrites of the neuron pathogens attacking the dendrites of the neuron red blood cells bathing the neuron

Elephants in the savanna regions of africa dig holes in dried up river beds to reach water lying just below the surface. these holes provide drinking water for other animals as well. so, without the elephants, many animals might otherwise die from lack of water during the dry season. the location in which the elephants live is an example of a/n and the role they play in creating water holes is an example of a a) ecosystem; habitat b) community; niche c) habitat; niche d) niche; habitat
