why not test for pathogens like salmonella directly rather than use an indicator organism such as a coliform?
Indicator organisms are organisms that are utilized to detect the presence of another organisms that cannot be easily identified.
We do not test for pathogens like salmonella directly but use an indicator organism like coliform because these pathogens are not easily isolated and they are much harder to identify.
Pathogens like salmonella are not tested for directly because they are much lower in numbers when found in wastes or waterbodies and to identify them directly is expensive.
Also testing directly for these micro-organisms is very expensive and non-viable. So it is better to use indicator organisms to detect their presence.

I know I'm late but I too am taking the Phenomenon #2 Assessment (Part 1) and want to help any future readers : )
(I pretty much gave you guys the answer but the little facts might still help, so I didn't give the direct answer in the start)
Explanation:
Mitosis: A type of cell division that results in 2 identical daughter cells.
* Process responsible for us getting bigger
*Process that repairs damaged cells
*grows new skin for us when cut
(took this out of my teachers lesson/ CC)
While...
Cell differentiation is:
Same DNA, just different genes get expressed!
This is the reason we look different are we get older! (Not the reason we grow)

Which researcher theorized that hypnosis comes about as a form of roleplay between hypnotist and subject? A. Ernest Hilgard B. Theodore Sarbin C. Theodore Barber D. Milton Erickson Please select the best answer from the choices provided A B C D
Answer:
Hey, your answer should be D
Explanation:
Good luck friends
The researcher who theorized that hypnosis comes about as a form of roleplay between hypnotist and subject is Milton Erickson, who is in Option D. Milton Erickson was a famous American psychiatrist and psychotherapist.
What is Milton Erickson?He is widely known for his pioneering work in the field of hypnosis. He believed that hypnosis is a form of communication between the hypnotist and the subject and that it involves a process of "roleplay" in which both parties take on certain roles or identities. In this sense, the hypnotist takes on the role of a facilitator or guide, helping the subject access their own inner resources and abilities. The subject, on the other hand, takes on the role of an active participant in the hypnotic process, using their own imagination and creativity to bring about positive changes in their thoughts, feelings, and behaviors.
Hence, the researcher who theorized that hypnosis comes about as a form of roleplay between hypnotist and subject is Milton Erickson, who is in Option D.

How was Dr. Martin Luther King , Jr. , an important force in creating a more just world ?
Evidence and reasoning plz
Martin Luther King, Jr. worked hard to bring greater equality to America and ensure civil rights for all people, regardless of race.
True or false: Theoretically, it is possible (but very difficult) for a population to not evolve for a while.
It is true that it is possible for a population to not evolve for a while.
There is something called the Hardy-Weinberg theorem, which characterizes the distributions of genotype frequencies in populations that are not evolving.
There are 5 Hardy-Weinberg assumptions:
no mutation random mating no gene flow infinite population size and no selection (natural nor forced).You can see that some of these are kinda extreme and really hard to get, but with approximations, we can work.
For example, instead of an "infinite population size" we have enough with a really large population, such that genetic drift is negligible.
Concluding, yes, it is possible (but really difficult) for a population to not evolve for a while (at least, in nature), as long as the 5 assumptions above are met.

Explanation:
4. Arrange Write the following steps in the order in which they occur during glycolysis
A six-carbon molecule is broken down into two three-carbon molecules.
Two NADP molecules are converted into two NADH molecules.
Two phosphate groups from two ATP molecules are joined to glucose.
Two three-carbon molecules are converted into two Folecules of pyruvate as four
molecules of ATP are produced.
The correct order of glycolysis reactions is:
Two phosphate groups from two ATP molecules are joined to glucose.Two NADP molecules are converted into two NADH molecules.A six-carbon molecule is broken down into two three-carbon molecules.Two three-carbon molecules are converted into two molecules of pyruvate as four molecules of ATP are produced.During glycolysis, the glucose molecule is converted to Glucose-6-phosphate as a result of phosphorylation. The phosphate group from ATP is joined to the glucose molecule by an enzyme known as hexokinase.
The glucose-6-phosphate then undergoes isomerization to become fructose-6-phosphate which is then phosphorylated again by the hexokinase enzyme to become fructose-1,6-biphosphate.
An aldolase enzyme converts fructose-1,6-biphosphate to one molecule of glyceraldehyde-3-phosphate and one molecule of dihydroxyacetone phosphate. The latter is then converted to another molecule of glyceraldehyde-3-phosphate.
A dehydrogenase enzyme converts glyceraldehyde-3-phosphate to 1,3-bisphosphoglycerate with NADH being generated from the reduction of NAD+.
A kinase enzyme then converts 1,3-bisphosphoglycerate to 3-phosphoglycerate with ATP being generated from ADP. A mutase enzyme quickly converts the 3-phosphoglycerate to 2-phosphoglycerate while an enolase enzyme converts the latter to phosphoenolpyruvate.
Finally, a pyruvate kinase enzyme converts phosphoenolpyruvate to pyruvate with another ATP being generated.

a/an ___ is a blood clot attached to the interior wall of a vein or artery.
Answer: a thrombus
A thrombus may also form in your heart
A thrombus is a blood clot attached to the interior wall of a vein or artery, which is option a. So the correct option is option a, as thrombus formation occurs when blood coagulation factors are activated and form a clot within a blood vessel.
Thrombi can occur in veins (venous thrombosis) or arteries (arterial thrombosis). In veins, a thrombus can lead to deep vein thrombosis (DVT), which commonly occurs in the lower extremities. If a thrombus dislodges from its site of origin and travels through the bloodstream, it is called an embolus, and it can potentially cause an embolism in another location. So the correct option is option a.
