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 1

Answer:

A: measuring the pH

E:checking for reactivity with vinegar

Explanation: I don't have one

Answer 2

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.

You might then also realize that the new method, at least on paper, may have additional applications. ... which makes the technology attractive to yet more scientists.

Explanation:

Hoped I helped you out please mark me brainliest!!!

With the creation of the microscope, humans were able to observe plant and animal cells, and as technology advanced, scientists were able to learn more about these various types of cells.

What is a microscope?

A microscope is a device that can be used to examine small objects, including cells. The image of an object is magnified in the microscope by at least one lens.

In most cases, the light is focused on the sample by passing it through a condenser.

After passing through the sample, the light passes through the objective lens, which magnifies the image of the sample, and then to the oculars, where the enlarged image is viewed.

The discovery of the green fluorescent protein (GFP), the development of increasingly sophisticated microscopes, and the development of in vitro assays that faithfully reproduce cellular functions are just a few examples of technological advances that have fueled many areas of cell biology.

Thus, it can be concluded that the advancements in technology help scientists better understand process of cell division.

how does asexual reproduction limit variation in species?

Answers

Answer:

less of a chance for mutations

Explanation:

Answer:

Asexual reproduction is a cheap and fast method for producing large numbers of propagules having little diversity. The method of cell division is mitosis, which produces identical daughter cells. This is largely advantageous when survival of offspring is dependent, more upon explosive population growth, than on the diversity of each individual. Plankton species are such an example, where to survive they mostly just need to out produce predation.

Most organisms engage in sexual reproduction at some point in their life cycle to introduce diversity when survival is dependent on susceptibility to parasites. Host — parasite coevolution is an arms race accelerated by diversity.

In sexual reproduction, the method of cell division is meiosis, where diversity is introduced through crossing over, independent assortment, and also, random fertilization.

hypothesis on what is the effect of the genes of the parental mice on the fur color of the offspring mice? use "If...then...format

Answers

Answer:

If the GENES of the parental mice encodes for a black fur, THEN the FUR COLOR of one of the offspring mice will be black.

Explanation:

Hypothesis is one of the steps used in the scientific method. It is a testable explanation of a given question or observation. Hypothesis in an experiment must be subjected to testing via experimentation in order to determine whether to reject it or not.

Hypothesis is usually constructed in the IF, THEN format. It tells us how the independent variable (cause) affects the dependent variable (outcome). In this case, a question is asked this: "what is the effect of the genes of the parental mice on the fur color of the offspring mice?"

A possible hypothesis will be: If the GENES of the parental mice encodes a black fur, THEN the FUR COLOR of one of the offspring mice will be black.

Answer:

A. If either parent mouse passes a dominant allele, the offspring will have black fur.

Explanation:

The human blood group is classified into four major classes which are A, B, AB, and O. This is possible due to multiple allelism and codominance which are found in the alleles A and B.

What is blood typing?

A blood type is the classification of blood into different groups, based on the presence or absence of antibodies and inherited antigenic substances on the surface of the red blood cells which are present in the blood. These antigens may be proteins, carbohydrates, glycoproteins, or the glycolipids, depending up on the blood group system.

In humans, the blood typing is of four types that is A, B, AB, and O. This is because, the blood typing is an example of multiple allelism and codominance. A and B alleles are codominant and O is recessive.

A. It conserves more fossil fuels.
B. It uses the same amount of fuel per person.
C. It uses more expensive fuel per person.
D. It uses more fossil fuels per person

Answers

Answer: A. It conserves more fossil fuels

Explanation:

This approach saves more fossil fuels than using lots of gasoline-powered cars, each with just one occupant.  So, the correct option is A.

What are Fossil fuels?

A fossil fuel is a hydrocarbon-containing substance that is recovered and used as fuel that naturally forms in the Earth's crust from the remains of dead organisms and plants. Fossil fuels include coal, oil, and natural gas. Fossil fuels can be burned to produce energy, drive engines, or provide heat for immediate use.

A general name encompassing non-renewable energy sources such crude oil, petroleum products, natural gas, derived gas, coal, coal products, and non-renewable wastes is "fossil fuel." These fuels are made from ancient geologically-dated plants and animals (for example, millions of years ago). Compared to using many single-occupant gasoline-powered cars, the method conserves more fossil fuels.

Therefore, the correct option is A.

A scientist is using a microscope to observe a type of

Which two structures would the scientist most likely see?PLEASE EXPLAIN WHY

A:nucleus and DNA
B:DNA and cell wall
C:cell wall and vacuole
D:vacuole and nucleus

Answers

Answer:

The two structures most likely to be observed by the scientist when looking at a type of bacteria under the microscope are cell wall and vacuole (option C).

Explanation:

Bacteria are prokaryotic organisms that lack a nucleus, most of the organelles, and whose DNA is dispersed in the cytoplasm. Some types of bacteria have a plasma membrane surrounded by a cell wall, and may be equipped with vacuoles to perform their functions.

It is very likely that two structures that are most likely to be differentiated when a type of bacteria is observed under the microscope are the cell wall and the vacuole, according with information above.

The other options are not correct because:

    A and D. Bacteria lack a nucleus.

    A and B. Bacterial DNA is dispersed in the cytoplasm and is very difficult to observe under the microscope.

What are the functions of mRNA?

Messenger ribonucleic acid is a single-stranded molecule of RNA that corresponds to the genetic sequence of a gene, and is read by a ribosome in the process of synthesizing a protein.

The role of mRNA is to carry protein information from the DNA in a cell's nucleus to the cell's cytoplasm (watery interior), where the protein-making machinery reads the mRNA sequence and translates each three-base codon into its corresponding amino acid.

Found in all cells, messenger ribonucleic acid, or mRNA, is a single-stranded molecule. It is responsible for transferring genetic information from DNA, found in the nucleus of the cell, to ribosomes floating in the cell's cytoplasm.
