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.

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

GIVING BRAINLIEST TO THE PERSON WHO HELPS ME!
Answer: The history of science is also a history of people resisting new discoveries that conflict with conventional wisdom.
Explanation: When Galileo promoted Copernicus’ theory that the Earth revolves around the sun – counter to church doctrine about the Earth being the center of the universe – he wound up condemned by the Roman Inquisition in 1633. Charles Darwin’s theory of evolution – that new species develop as a result of natural selection on inherited traits – ran into opposition because it contradicted long-held scientific, political and religious beliefs. Alfred Wegener’s 1912 proposal that Earth’s continents move relative to each other – the theory of continental drift – was rejected for decades, in part because scientists held fast to the traditional theories they’d spent careers developing.

what are the cells that divide to produce gametes ?
Answer:
cells needed for sexual reproduction
Explanation:
so that during fertilization,the total number of chromosomes will be 46..
What are the cells that divide to produce gametes? germ cells
What is a gamete?It is the reproductive cell of an organism. They are haploid in nature.
How many types of gametes are there?There is a male gamete that is termed sperm (animals) or pollen grain (plants) and a female gamete that is termed ovum (animals) or egg (plants).
What kind of division occurs prior to gamete formation?Meiosis, or reductional division, occurs prior to gamete formation.
What is its significance?It ensures that after fertilization, the normal diploid number is maintained.
What kinds of cells undergo this division to produce gametes?Germ cells are the cells that produce gametes.

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.

Bacteriophage and E.coli are alike in the sense that they both lack membrane-bound organelles.
What are bacteriophage?Viruses that infect bacteria are called bacteriophage. The words bacteriophage mean "bacteria eater". Bacteriophages take over the machinery of host cells to produce copies of themselves and then destroy the host cell in the process.
Bacteriophages are composed of a supercoiled nucleic acid which is surrounded by a protein capsid.
A bacteriophage adheres to the surface the susceptible bacteria and injects its genetic material. This way they occupy the genetic machinery of the host and produce several copies of their own nucleic acid and also the protein capsid to surround it.
The result is the lysis of bacterial cell and release of thousands of bacteriophage viruses which are capable of infecting more bacteria in the same manner.
Bacteriophage are acellular structures lacking any membrane bound cell organelles. E.coli is a kind of prokaryotic bacteria which also lack membrane bound organelles.
Therefore, the correct option is D.

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.
