What kind of plant growth hormone to regular plant growth. We dissolve 5.0 mg of the solution into 2.0 kg of water. What is the dosage of the solution in ppm? _ppm

Answers

Answer 1

Answer:

The dosage of the solution is 2.5 parts per million.

Explanation:

The solvent proportion in parts per million is equal to the ratio of solution in miligrams to ratio of water in miligrams multiplied by a million. (A kilogram is equivalent to a million miligrams) That is:

\(p.p.m. = \frac{5\,mg}{2000000\,mg}\times 1000000\)

\(p.p.m. = 2.5\, ppm\)

The dosage of the solution is 2.5 parts per million.

a scientific belief that was accepted centuries ago, but has since been disproved. How does it support the use of the term "scientific theory" instead of "scientific fact?"

Answers

Answer:

In the past was believed that species were fixed entities

Explanation:

Before Darwin's evolutionary theory (in which all living things arise through descendants with modification), Linnaeus had proposed that species were immutable entities. Although it was an erroneous concept, this belief enabled the development of a system for classifying and naming organisms. Indeed, Linnaeus is nowadays recognized as the father of taxonomy to create this system. This example shows that scientific knowledge is not based on factual information, but it is a process that progressively increases our understanding of the real world.

How is a chemical change different from a physical change?

Answers

Chemical change is different from physical change because physical change is the appearance or form changes. but the matter in the substance does not change. but in chemical change the kind of matter changes and at least one new substance with new properties is formed. *you can add more punctuations to make it 5-7 if you would like:)*

In a physical change the appearance or form of the matter changes but the kind of matter in the substance does not.

how to use a microscope> Everything I need to know

Answers

Do not touch the glass part of the lenses with your fingers. Use only special lens paper to clean the lenses.
Always keep your microscope covered when not in use.
Always carry a microscope with both hands. Grasp the arm with one hand and place the other hand under the base for support.

Step 1: Set Up the Microscope. ...
Step 2: Clean the Lens. ...
Step 3: Prepare a Slide. ...
Step 4: Insert the Slide. ...
Step 5: Set Up for Viewing. ...
Step 6: Set the Light Control. ...
Step 7: Focus the Microscope. ...
Step 8: Increase Magnification.

Answer:

Keep in mind this changes from microscope to microscope.

Explanation:

On most classroom microscopes, there will be two knobs on either side of the scope. These will increase or decrease the height of the "stage", which is how you "focus" the microscope. The larger knob will move the stage the most, and thus, is called the coarse focus. The smaller knob is called the fine focus, and, you guessed it, will move the stage the least. There are usually three "objective lenses". Each will have a different magnification and will be listed on the lens itself. It rotates around the "revolving nosepiece". MAKE SURE THAT THE SLIDE IS LOWERED BEFORE ROTATING THE LENSES!!!! If you don't you WILL break the slide and you WILL get death looks from the teacher.

On the stage, there are two clips. They move NOT up and down, but they spin. what you want to do is to move the slide into the clips. They will not break if you do not bend them more than what the slide will bend them to.

The technique for focusing the microscope is really easy once you do it a few times. After making sure that the microscope is plugged in and the light on and the slide and lens in the lowest position/magnification (!) move the coarse focus knob so that the object in the slide is just visible. Once you do that, from there use the fine focus knob to make the object most visible.

These instructions vary slightly from model to model of microscope, but the picture below is very accurate and everything I warned you about is for all microscopes.

Mario uses a hot plate to heat a beaker of 50mL of water. He used a thermometer to measure the temperature of the water. The water in the beaker began to boil when it reached the temperature of 100 C. If Mario completes the same experiment with 25mL of water, what would happen to the boiling point?

Answers

Answer:

nothing

Explanation:

as long as he's using pure water, there will be no change to the boling temperature. boiling point depends on the purity of the substance, not volume. so the temperature at which mario's water boils remains 100C.

The offspring resemble the parent, which makes it difficult to distinguish them from each other.

The offspring are genetically identical to each other, which reduces their ability to adapt to any changes in the environment.

Answers

Answer:

The offspring are genetically identical to each other, which reduces their ability to adapt to any changes in the environment.

Explanation:

If there was a disease (as an example) that negatively effected both organisms that reproduce asexually and sexually, the organisms that reproduce asexually would have a disadvantage. Offspring of the organisms that reproduce sexually contain the genetic material of both parents. This would lead to a higher chance of the ability to adapt to any changes, or even a chance of being immune to that disease. However, offspring of the organisms that reproduce asexually are only replicates of the parent. This means that the asexually produced offspring and the parent organism could be harmed more than the sexually produced offspring and parent organism. The organism would have reduced abilities to adapt according to the changes in the enviroment.

The major disadvantage for organisms that reproduce asexually is option 4 that the offspring are genetically identical to each other, which reduces their ability to adapt to any changes in the environment.

Asexual reproduction is a type of reproduction where only a single parent is involved in creating offspring. The offspring reproduced are genetically identical to the parent. while this form of reproduction has many advantages including rapid and quick reproduction, it posses some major drawbacks as well.

As the genetic diversity is absent in asexual reproduction, adapting and surviving in the dynamic environment is tough for the offspring. Difficulty in catching up with the changing circumstances can sometimes lead to harm to upcoming species.

1. Using D10W and a vial of NaCl 4 mEq/mL, how many mL of NaCl are needed to prepare 250 mL of a
D10/NS solution?
a. 4.8mL
b. 9.6ml
c. 19.6mL
d. 154mL

Answers

To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.

the correct answer is A 4.8 mL
