The concept that human and animal diseases are caused by microorganisms is called the germ theory
In medicine, germ theory is the belief that certain illnesses are caused by the body's attack by micro - organisms that are too small to see without a microscope.
The germ theory of disease indicates that micro - organisms like viruses, protozoa, bacteria, or fungi cause many diseases. The growth and reproduction of microorganisms cause these diseases.
Louis Pasteur developed the germ theory of disease. He also carried out a number of experiments to demonstrate the link between diseases and microorganisms.

Why is technology not the solution to all scientific problems?
Answer:
Below
Explanation:
Technology is only as smart as humans are. Sure, many humans can work on a single piece of technology, meaning that a computer or other piece of tech is smarter than any individual person, but they can still never reach beyond the intelligence of humanity.

a) The carbohydrates cellulose and starch are functionally different due to the ____?
A. Reaction used to join their monosaccharides.
B. Specific monosaccharides used to build them.
C. Arrangement of their monosaccharides.
D. Functional groups contained within their monosaccharides.
b) Why is that the answer?
a) The answer is C. Arrangement of their monosaccharides.
b) The reason for this answer is : The main distinction between starch and cellulose is that starch is a storage polysaccharide with alpha 1,4 links between glucose monomers, whereas cellulose is a structural polysaccharide with beta 1,4 connections between glucose monomers. The primary distinction is that while plants employ cellulose to construct structure, they use starch to store energy. In contrast to cellulose, where each succeeding glucose unit is rotated 180 degrees, starch repeat units are situated in the same direction. Compared to sugar, which is not water soluble, cellulose is thicker. On the other hand, starch may be dissolved in warm water and is less brittle than cellulose. Since mammals absorb starch, cellulose is not suitable for human diet.

Platelet transfusion is to be administered to a child with acute lymphocytic leukemia. which step would the nurse do first?
If platelet transfusion is to be administered to a child with acute lymphocytic leukemia then, the nurse would first : administer the platelets rapidly through the intravenous (IV) line.
Platelets are delicate and should be infused as soon as the child is able to tolerate it or as quickly as the young patient's cardiovascular condition will allow, ideally within an hour. A severe reaction is less likely because the infusion contains little in the way of white blood cells (WBCs) and red blood cells (RBCs).
What does platelet transfusion actually entail?
In patients with low platelet counts or functional platelet disorders, platelet transfusion is a life-saving procedure used to stop ongoing bleeding or stop potential bleeding. As not all low platelet levels call for a transfusion, there are minimum thresholds at which platelets are given to these patients. Due to the time and effort required to precisely prepare, process, and transfuse platelets while maintaining a certain quality, platelets are a scarce resource.

Which class of antidiabetic drugs inhibits alpha glucosidase and delays glucose absorption?
Alpha-glucosidase inhibitors are a class of antidiabetic drugs that inhibits alpha-glucosidase and delays glucose absorption.
Alpha-glucosidase inhibitors are abbreviated as AGIs. AGIs inhibit the absorption of carbohydrates in the small intestine by inhibiting the action of enzymes such as alpha-glucosidase. Alpha-glucosidase is an enzyme that converts complex carbohydrates (e.g. Starch) into simple absorbable carbohydrates like glucose. Other enzymes that perform a similar function include sucrase, maltase, glucoamylase, and isomaltase.
Acarbose is the most commonly used Alpha-glucosidase inhibitor taken orally. AGIs are initiated with a lower dosage taken three times with the meal. Acarbose inhibits the action of enzymes like alpha-amylase, maltase, sucrase, and dextranase.
Due to the action of AGIs to inhibit the carbohydrate converting enzymes, they are named so. And with this preference, AGIs are used to delay glucose absorption.

C. Run gel electrophoresis.
D. Make a karyotype.
The answer it’s B
Answer: B
In this phase, fragments of the DNA are separated OR segregated based on their sizes. DNA samples are placed in one end of gel and electricity is passed to drag them through the gel. The fragments of DNA are made up of negative charge, that’s why they move across the positive electrode. If this process will continue for long time , DNA will shift off the end of gel. To move through the gel it requires high voltage. If the voltage becomes very high it will lead to melting of gel or smearing of the DNA bands.

It's a chocolate-based introduction to the rock cycle!
Like rocks, chocolate can be squeezed, heated, cooled, and weathered into tiny particles. Chocolate can go through these processes safely and at normal temperatures, unlike rocks.
Create "sedimentary," "metamorphic," and "igneous" chocolate using your supply of chocolate. Make a wonderful treat at the end of it all!
Materials:
Blocks of white and dark chocolate Cupcake liners made of aluminum foila container to hold the hot watera plastic knife or another straightforward scraperMaking "sedimentary" chocolate first:
1. Scrape a few tiny pieces of chocolate from your blocks.
2. Place all of these scrapings on a piece of aluminum foil and push down. You could press the chocolate shavings onto the aluminum foil after folding it. You may even stand on foil packets that were sealed.
3. Note how the consolidated group of chocolate scrapings in the foil now resembles sedimentary rock.
Make "metamorphic" chocolate next:
1. Fill some aluminum foil or a cupcake holder with a small pile of your sedimentary chocolate, possibly some of your original unused scrapings, and a few small chunks from your initial blocks.
2. Float this mixture in water that is moderately heated.
3. Keep an eye on the foil and chocolate as they begin to melt when the heat from the water is transferred to them.
4. When the chocolate feels soft to the touch, remove the foil (for safety, use the plastic knife, not the fingers).
5. Allow the chocolate to cool. The chocolate has now chilled and only half melted, resembling metamorphic rock.
Make "igneous" chocolate next:
1. Fill your aluminum foil or cupcake holder with a tiny mound of sedimentary and metamorphic chocolate and a few pieces from the initial blocks.
2. Float this mixture in extremely hot water.
3. Observe how the heat from the water is transferred to the foil and melting chocolate. The chocolate should be allowed to melt until smooth liquid forms.
4. Carefully remove the melted chocolate from the aluminum container and let it cool. Now that your chocolate has melted and cooled, it resembles volcanic rock.

What condition will increase the diffusion of molecules, such as neurotransmitters?
An increase in the number of neurotransmitters exocytosed by the presynaptic axon will increase the diffusion of molecules such as neurotransmitters.
what are neurotransmitters?
Any of a group of chemical agents released by neurons (nerve cells) to stimulate surrounding neurons, muscle cells, or gland cells allows impulses to be transmitted from one cell to the next throughout the nervous system. This is known as a neurotransmitter, also known as a chemical transmitter or chemical messenger.
These neurotransmitters are stored in synaptic vesicles of the axon terminals and are released during transmission of impulses from one neuron to another.
Neurotransmitter molecules are instantly destroyed by enzymes in the synaptic cleft after being released and binding to postsynaptic receptors; they are also absorbed by receptors in the presynaptic membrane and recycled.
Hence, if they are released in large amounts from the synaptic vesicles their diffusion will increase automatically.
