Biology - label a flowchart - Synthesis of a lagging strand?
http://session.masteringbiology.com/problemAsset/1108498/24/1108498_008.jpg This question relates to the image above. In contrast to the leading strand, the lagging strand is synthesized as a series of segments called Okazaki fragments. The diagram below illustrates a lagging strand with the replication fork off-screen to the right. Fragment A is the most recently synthesized Okazaki fragment. Fragment B will be synthesized next in the space between primers A and B. 1 - pol III binds to 3' end of primer B 1 -> 2 -> 3 -> 4 -> 5 The Options for 2, 3, 4 and 5 as a flowchart are below, and I have put them in the order that I believe they are correct, but would appreciate review to see if this is correct. 2. pol III moves 5' to 3' adding DNA nucleotides to primer B 3. pol I binds to 5' end of primer A 4. pol I replaces primer A with DNA 5. DNA ligase links fragments A & B
Correct sequence of events in the prosess of synaptic transmission?
As the action potential reaches the end of the first neurone, Ca2+ channels are also opened. Ca2+ flows into the cell and this induces several hundred vesicles containing the neurotransmitter to fuse with the presynaptic membrane. The neurotransmitter is released into the synaptic cleft. The molecules of neurotransmitter bind with complementary receptors (similar to an enzyme and substrate fitting together) in the postsynaptic membrane. This makes the Na+ channels open and depolarisation occurs in the postsynaptic membrane thus starting an action potential.
Business Process Management: What are the best available tools for workflow automation?
We're doing this withTallyfy- and integrating with common workflow/recipe/productivity services, since no single company can solve this entire problem.Please note that many simple tools in this answer are claiming to have "workflow" capabilities when they are nothing more than a pretty checklist editor.Whilst processes can be expressed as flowcharts, it's important to understand that nobody follows flowcharts in practice, and they are impossible to track in real-time. so whatever approach you take for workflow automation is doomed to fail unless you express the steps as a simple list.The "powerful" part of this is when the steps are computed in real-time, across many people. That's the cutting edge for workflow automation. It also means that end-users find it really simple to get things done, without trying to look at flowcharts.It sounds like what you really need is powerful conditional branching such as that highlighted in the examples below. Although these are expressed as flowcharts below, they would be computed in real-time by Tallyfy. The end-user does not see flowcharts in Tallyfy - they just see steps, which appear in real-time based on conditional IFTTT (if this then that) rules.Are the conditional scenarios below correct for your automation problem?
What is the answer to this question? Suppose we have 5 blue marbles and 5 red marbles in a bag, and we pull out one marble which may be blue or red. Now there are 9 marbles left in the bag. What is the probability that the second marble will be red?
The event you’re interested in is the 2nd marble being red so we only need to consider 2 events: Blue 1st, Red 2nd (B, R) and (R, R).With (B, R) you have 5 blue marbles out of 10 then still the original 5 red marbles but this time out of 9 since you didn’t replace the first one. Multiplying the probabilities gives us the joint event. Note this requires conditional probability.Pr(B, R) = Pr(B)*Pr(R | B) = (5/10)(5/9) = 25/90 = 5/18 = 0.2778For (R, R) you have 5 reds out of the bag of 10 marbles then 4 left in the bag of 9.Pr(R, R) = Pr(R)*Pr(R | R) = (5/10)(4/9) = 20/90 = 2/9 = 0.2222Those are disjoint events so we can simply add the probabilities.Pr[(B, R) OR (R, R)] = Pr(B, R) + Pr(R, R) - Pr[(B, R) AND (R, R)]= 25/90 + 20/90 - 0= 45/90= 1/2= 0.5So there is a 50% chance the second marble drawn will be red. Interestingly the result would be the same if you put the 1st marble back in after observing it (sampling with replacement). The 2nd draw is independent of the 1st.Pr(B, R) = Pr(R, R) = (5/10)(5/10) = (1/2)(1/2) = 1/4Pr[(B, R) OR (R, R)] = (1/4) + (1/4) = 1/2
What is the order of blood flow if a drop of blood would pass through the following heart structures as it returns to the heart from the systemic circulation?
The path would be: Right AtriumTricuspid valveRight VestibulePulmonary valvePulmonary arteriesLungsPulmonary veinsLeft AtriumBicuspid (Mitral) valveLeft ventricle Aortic valveAortaAll the body.And I mean all of it, the first branches are Coronary arteries that feed the heart with the blood supply and there are even two Bronchial arteries that go to the lungs again.Superior vena cava and Inferior vena cavaSuperior vena cava returns [almost] all the blood from head and neck, upper limbs and chest to the heart. Inferior vena cava returns all the blood from under the diaphragm and some of the chest's back to the heart.Right atrium again.(Image from Wikipedia)(Image from Wikipedia)PS. It's a cycle, you can start it from anywhere but since you wanted the blood's path as it returns to the heart from the systemic circulation, your answer should start with the right atrium.
