Answer the following questions.
What is the difference between a physical change and a chemical change?
What kind of change occurred in each test? What evidence do you have to support your decision? Be brief, but be sure to defend your conclusion with data.
FIRST PERSON TO ANSWER GETS BRAINLY
1. A physical change occurs when the chemical composition of a substance does not change, but only its physical properties. An example of this would be melting ice. A chemical change occurs when the chemical composition of a substance is altered. An example of this would be the formation of rust from iron.
2. In order to answer this I would need to see what tests the question is referring to.
But you could find one physical change and one chemical and use something like this:
Test 1:
A physical change occurred in Test 1. This is supported by the fact that the substance retained its original chemical composition but changed its form.
Test 2:
A chemical change occurred in Test 2. This is supported by the fact that a new substance was created which had a different chemical composition than the original substance.
why are fat cells larger than red blood cells
AnswerLarger mammals don't typically have bigger cells; they just have more of them, is the typical response to the question of whether they are bigger in larger mammals than in smaller ones. For example, compare the liver cells of an elephant and a mouse.
Red blood cells, liver cells, and other cell types that often split and replace themselves are all around the same size; however, in large animals, permanent, long-lived cells like brain and fat cells are larger.
Explanation:
Fat cells, also known as adipocytes, are larger than red blood cells because they have different functions in the body. Red blood cells are responsible for carrying oxygen from the lungs to the body's tissues, while fat cells store energy in the form of fat.
Fat cells are much larger than red blood cells because they need to be able to store a large amount of fat. A single fat cell can contain up to 50,000 times more fat than a red blood cell. This allows the body to store a significant amount of energy that can be used during times of increased energy demand or when food is scarce.
Red blood cells, on the other hand, are much smaller because they need to be able to circulate throughout the body and fit through the small blood vessels. They have a flattened, disk-like shape and are only about 7-8 micrometers in diameter. This is much smaller than fat cells, which can be up to 100 micrometers in diameter.
Overall, the differences in size and function between fat cells and red blood cells reflect the different roles they play in the body.

To stop the transpiration of water, the stomata occasionally close.
What adaptations does this plant have that allow it to survive in arid and dry conditions?Plants need to reduce transpiration to reduce water loss if they are to survive in a drought. Some plants that grow in arid environments have evolved to have smaller leaves and fewer stomatale sharp thorns as a result.
What adjustments are necessary for a plant in a dry environment?The leaves of these plants have a thick cuticle layer, which lessens transpirational water loss. Their extensive tap roots sink far into the soil to absorb water. Succulent plants store water in their stems, roots, leaves, and even fruits. Their waxy covering also prevents transpirational water loss.

a stock solution has been diluted at 16 fold. It is now 80 micro mol. What was the original stock concentration in Milli moles?
The original stock concentration in Milli moles will be nearly 1280 millimole.
What is concentration?
Concentration in chemistry is calculated by dividing a constituent's abundance by the mixture's total volume.
Mass concentration, molar concentration, number concentration, and volume concentration are four different categories of mathematical description.
The quantity of a substance, like salt, that is present in a specific volume of tissue or liquid, like blood, according to science. When there is less water present, the material becomes more concentrated.
(C1) (V1) = (C2) is the formula for determining a dilution (V2)
C1 = concentration of the starting solution.
V1 = volume of the starting solution.
C2 = concentration of the final solution.
V2 = volume of the final solution.
Here,
C1 = x
V1 = 1000 micro mol
C2 = 16
V2 = 80 micro mol
So,
1000x = 16 x 80
x = 1280/1000
x = 1.280
Thus, the original stock concentration is 1280 millimole.

What is a Vaccine?
A vaccine is basically a biological preparation that provides active acquired immunity to a particular disease. It contains an agent that resembles a disease-causing microorganism and is often made from weakened or killed forms of the microbe, its toxins or one of its surface proteins. Vaccines are designed to stimulate the body's own immune system to protect the person against subsequent infection or disease.
11) An antigen is a substance that causes the body to produce antibodies when it enters the body. These antibodies help the body recognize and fight the antigen if it enters the body again.
12) A vaccination is a way of introducing a weakened or killed version of a particular virus, bacteria, or toxin into the body. This weak or dead version of the virus, bacteria, or toxin stimulates the body's natural defense system to produce antibodies that are specific to that virus, bacteria, or toxin. These antibodies can then recognize and fight off the real virus, bacteria, or toxin if the body is ever exposed to it, thus preventing the individual from getting the disease. This is known as active immunity. The immunity created by the vaccination is typically long-lasting, and in many cases, lifelong.
