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.

DONE
Prokaryotes are less complex than eukaryotes and lack a nucleus. They also contain a flagellum outside of their cell.
Where does the DNA of prokaryotes reside?
Prokaryotes have a nucleoid in the center of the cell that houses the DNA but is not protected by a nuclear membrane. In addition to chromosomal DNA, many prokaryotes also possess smaller, circular DNA molecules known as plasmids, which can provide genetic benefits in particular situations.
Do prokaryotic chromosomes exist?
Prokaryotic cells lack a membrane-bound nucleus, in contrast to eukaryotic cells. Instead, the nucleoid, a part of the cytoplasm, is where their genetic material is located. Typically, a prokaryotic cell contains just one circular, coiled chromosome.

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.

A plant stem's two main functions are to support the leaves and to transport materials
between roots and leaves. As a stem develops, it possesses three types of permanent
tissues: surface tissue, ground tissue, and vascular tissue. The surface and ground
tissues support and give structure to the plant. The vascular tissues are the transport
systems of the plant. The vascular tissues usually exist in one of three patterns and are
known as the phloem and xylem.
Both the xylem and phloem are made up of several different types of cells that make up
transport tubes for needed nutrients. In general, xylem nutrients (sap) travel from the roots
to the rest of the plant. Phloem sap is derived from photosynthesizing leaves and from
there is carried throughout the plant.
What would we be able to study by injecting a nutrient dye into the root of a plant?
A. phloem sap transport
B. pith and cortex cells
C. all vascular tissues
D. xylem sap transport
OE. total plant photosynthesis

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.

Which of the following does not indicate velocity?
A. 14 feet per second per second
C. 80 miles per hour towards New York
B. 40 miles per hour towards town
D. 28 miles per second towards Ohio
Answer:
A. 14 feet per second per second does not indicate velocity.
Explanation:
Velocity has formula of displacement over time. Displacement can have unit such as mile, meter, kilometer, etc while time can have unit such as second, hour, minute, etc.
With division rule of term, we would have unit of measurement over unit of time, thus velocity only have one-degree term (no power term).
Unlike acceleration, acceleration has square term in time unit because acceleration is change in velocity over time. Velocity has unit of measurement over unit of time, with these units dividing another unit of time, we have:
[tex] \displaystyle{ \dfrac{ \text{measurement}}{ \text{time}} \div \text{time} = \dfrac{ \text{measurement}}{ \text{time}} \times \dfrac{1} {\text{time} } \to \dfrac{ \text{measurement}}{ \text{time}^{2} }}[/tex]
Hence, acceleration would have time² unit while velocity only has time¹ unit.
And as seen in the choices, only unit that appears as time² is A choice as feet per second per second means (feet/second)/second = feet/sec² and this is acceleration, not velocity.

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.
