Explanation:
For the Hill Reaction, you used DCIP dye at a concentration of 1x10-4 M. Our lab technicians have stock solution at a concentration of 100mM. Explain how you would make 100mL of the DCIP for you to use in a Hill Reaction lab.
Answer:
by diluting the DCIP dye stock solution 1000 times. It can be done by diluting 0.1 ml of the DCIP dye stock solution with 99.9 ml of distilled water
Explanation:
1 millimolar (mM) = 0.001 M
1.0 × 10⁻⁴ Molar (M) = 0.0001 M = 0.1 mM
Stock solution = 100 mM = 0.1 M
100 mM DCIP dye solution diluited 1000 times >> 0.1 mM = 1 x 10⁻⁴ M

What is the short definition of a plant cell?Plant cells are eukaryotic cells with a genuine nucleus and particular organelles to carry out particular tasks. Plant cells do, however, include several organelles that are unique from those seen in other eukaryotic cells.
Where can you find plant cells?Roots, stems, leaves, flowers, and reproductive structures are only a few of the major classes of cells and tissues that are formed when plant cells differentiate from undifferentiated meristematic cells, which are similar to the stem cells of animals.

Sea otters move into the ocean bay. The eat all the sea urchins. This change will cause the
A. Kelp to have less food
B. crabs to have less food
C. Sea ducks to have more food
D.Arctic foxes to have more food
The presence of sea otters in an ocean bay will result in a reduction in the amount of food available to carbs because they feed on sea urchins. Therefore, option (B) is correct.
What is food chain?The linear relationship between creatures that demonstrates how they obtain energy by feeding on one another is referred to as the food chain.
The information provided in this inquiry suggests that sea otters migrate into the ocean bay and consume all of the sea urchins there.
This leads one to believe that they cut down on the food supply of another eater of urchins, such as carbs. Because of this, the introduction of sea otters into the ocean bay will result in there being less food available for carbs.

Do you believe that all of our actions can be attributed to the nervous system? Does your memory of an event trigger your responses? Why or why not?
Answer:
The nervous system is made up of all the nerve cells in your body. It is through the nervous system that we communicate with the outside world and, at the same time, many mechanisms inside our body are controlled. The nervous system takes in information through our senses, processes the information and triggers reactions, such as making your muscles move or causing you to feel pain. For example, if you touch a hot plate, you reflexively pull back your hand and your nerves simultaneously send pain signals to your brain. Metabolic processes are also controlled by the nervous system.

HELP PLZZZ!!!......Which feature is created by wave erosion?
A)loess
B)delta
C)rill
D)stack
Answer:
the answer is d stack
Explanation:
A feature which is created by wave erosion is Stack. Thus, the correct option is D.
What is Wave erosion?Wave erosion can be defined as the waves which are creating a variety of landforms along with a shoreline. Sea cliffs generally occur when the waves erode rock, resulting in the high slopes formation. Wave energy results into production of erosional formations such as cliffs, wave cut platforms, sea arches, and the sea stacks. These all are features of wave erosion.
Sea wave erosion is accomplished primarily by the hydraulic pressure, the impact of waves that are striking the seashore, and through the abrasion that is wearing, grinding, or rubbing away by the friction by sand and pebbles that are agitated incessantly by the water and wave-cut platform.
Therefore, the correct option is D.

The complete question is as follows:
Regarding the General Adaptation Syndrome, a short term response to stress in which glycogen is broken down to glucose is characteristic of the stage. 1) Alarm reaction 2) Stage of resistance 3) Stage of exhaustion
Answer:
The General Adaptation Syndrome or GAS explains the pattern of responses that body experinces in response to prompted by a stressor. There are three phases of this syndrome:-
1. Alarm reaction:
Sympathetic system and Hypothalamopituitary axis activated by the stress result in reaction by body.
2. Stage of resistance:
The hormone that is releases continusoly in this stage by the zona fasciculata layer of adrenal cortex is cortisol to maintain arousal.
3. Stage of exhaustion:
In abscence of enough blood sugar or glucose in the body, the body initiates breakdown of the glycogen (stored sugar in muscles mosty) with the help of hormone known as glucagon to covert it to glucose so that it can be used by the cellular respiration.
Many signaling pathways have multiple transducer proteins, for example in a multi-enzyme phosphorylation cascade - one of the purposes for this is: _________.
a. to prevent damage to the receptor protein
b. to amplify the signal
c. all choices are correct
d. to avoid gene duplication
e. to conserve ATP and/or GTP
Answer:
b. to amplify the signal
Explanation:
A multi-enzyme phosphorylation cascade is a series of signaling events where one enzyme phosphorylates to another, then this last enzyme acts to phosphorylate another protein and so successively, thereby triggering a chain reaction that leads to the phosphorylation of hundreds or even thousands of proteins. A multi-enzyme phosphorylation cascade is known to increase the number of activated (phosphorylated) proteins at each step of the signaling cascade. Phosphorylation is a posttranslational modification capable of activating proteins during long periods, thereby a phosphorylation cascade also enables the activation of multiple proteins before these proteins become inactive again.
One of the purposes of a multi-enzyme phosphorylation cascade is signal amplification, as shown in option B.
We can arrive at this answer because:
A multi-enzyme phosphorylation cascade allows the emission of a sequence of signals, which occur simultaneously.These signals are created from a series of enzymes, each of which emits a signal by phosphorylating a protein.This all promotes thousands of phosphorylations to be promoted at the same time, all giving off signals.This simultaneous emission of signals extends the range of these signals and allows the phosphorylated proteins to emit more signals, further expanding their reception.In this case, we can state that the multi-enzyme phosphorylation cascade has the function of amplifying an emitted signal.
