ANSWER QUESTION PLZ TYSM!!
Answers
Answer:
Difference: Conductors are materials that permit electrons to flow freely from particle to particle. Conductors allow for charge transfer through the free movement of electrons. In contrast to conductors, insulators are materials that impede the free flow of electrons from atom to atom and molecule to molecule.
Similarities: Both conductors and insulators deal with the electric conductivity of a surface or material. Everything is either a conductor or an insulator. It is a conductor if it readily allows electrons to flow across it, when there is a potential voltage differential between two points on the surface.

In your lab group, you are investigating the properties of unknown types of matter. Your teacher gives you a "detective's kit
consisting of: vinegar (an acid), pH strips, and water. She asks you to design experiments to determine the chemical properties of the
unknowns. Select ALL of the experiments you might perform to observe chemical properties.
A)
measuring the pH
B)
measuring the mass
C)
measuring the density
D)
measuring the boiling point
E)
checking for reactivity with vinegar
Answers
Answer:
A: measuring the pH
E:checking for reactivity with vinegar
Explanation: I don't have one
The chemical property of the unknown substance can be measured by checking for reactivity with vinegar.
The chemical properties of a substance are those properties of a substance that we can observe by allowing the substance to be changed via a chemical reaction. In other words, chemical properties are observed by passing the substance through a chemical reaction.
Hence, the experiment that you will need to perform in order to determine the chemical properties of the unknown substance is checking for reactivity with vinegar.

The house fly, Musca domestica, has a haploid chromosome number of 6. How many chromatids should be present in a diploid, metaphase cell (metaphase of mitosis)
Answers
Question: The House Fly, Musca Domestica, Has A Haploid Chromosome Number Of 6. How Many Chromatids Should Be Present In A Diploid, Somatic, Metaphase Cell? The Answer Is 24.
24 chromatids should be present in a diploid, metaphase cell (metaphase of mitosis).
What is mitosis?Chromosome replication and equitable distribution between the two daughter cells occur during the cell division process known as mitosis. Each daughter cell has the same number of chromosomes as the parent cell, making them diploid. Hence, mitosis is sometimes referred to as equational division.
There are four phases in mitosis and that is prophase, metaphase, anaphase, and telophase.
Thus, If the house fly has a haploid chromosome number of 6, which means it has 12 chromosomes in a diploid state. When a cell undergoes mitosis, the diploid chromosome number of the cell becomes double. Therefore, there will be 24 chromatids in a diploid metaphase cell.

An investigator wishes to use animals in an experiment that involves category B, C, and D activities performed on the same animal. How should the animal be categorized
Answers
Answer:
Category D
Explanation:
In the USA, the Federal Animal Welfare Regulations require that research laboratories report animal use according to the species as well as the number of individuals subject to experimentation procedures. Moreover, animal use for research/teaching purposes is also reported according to the classification by pain and distress categories. Basically, this classification has four categories (B,C, D and E) in increasing order according to the pain level suffered by research animals. Animals within Category D include those subjected to potentially painful or stressful procedures. In consequence, in this category, it is imperative the utilization of proper anesthetics and/or analgesics in order to diminish the pain and suffering of these animals at the lower level possible.

- the amount of iron in blood depends on the amount of red meat a person eats.
Answers
Answer:
The answer is:
Independent: red meat eaten by a person
Dependent: iron in the blood
Explanation:
A dependent variable has to depend on something else, so in order for a dependent variable to exist or happen, there has to be the independent variable. The independent variable is something that does not need anything else to happen for it to take place. It s independent. Such as, a mother cannot have a child without sperm.

Explanation:
The D5NS is a solution of 5% of dextrose in the normal saline in addition it also contains saline 0.9% NaCl. It is used for intravenous glucose treatment. It is used for patients that have low blood glucose level and to maintain the electrolytic balance. Plasma on the other hand has a composition of water, hormones ,electrolytes, lipids, salts, proteins, fibrinogen, clotting factors, and immunoglobulins.
The blood plasma is a liquid matrix which comprises of proteins, fibrinogen, clotting factors, and immunoglobulins (antibodies) which are not present in the D5NS.
