If a Ca2+ channel opens in the plasma membrane, those ions will flow out of the cell by facilitated diffusion.

If this is the sequence of DNA, what RNA would be made from it?  Be sure to label the 5′ and 3′ ends. 3′ AATCGGTAGCA 5′

Lab simulations on Connect only use a mouse to engage with the virtual lab environment; there are no keyboard shortcuts for any actions in the virtual laboratory.

Which routing algorithm, Dijkstra or Bellman-Ford, is better at responding quickly to changing connections in the network, i.e., quicky creating new routing tables when one new node is added, or when a link goes down.   Answer Format Write your choice (Bellman-Ford or Dijkstra): [RoutingAlgorithm] Provide your reason for your choice: [Reason] (one or two sentences in text)

When performing a Virtual Lab simulation on Connect, you must take notes on your own paper, since there is no way to digitally take notes within the simulation itself.

When a particular concentration of protein molecules are all bound to substrate and all working at their maximum rate, we say that this population of proteins has reached a point of _________.

The following image shows the introns and exons for an mRNA.  The splice sites are labeled below the mRNA. What would be the consequence of blocking site number 3 under intron B so that the spliceosome could not find/recognize it?
