What foods below would test positive for starch in the presence of iodine?

Question 8 options:

a steak


a hard boiled egg


noodles, bread, or crackers


chicken

Answers

Answer 1

The group of foods that would test positive for starch in the presence of iodine would be noodles, bread, or crackers.

Noodles, bread, or crackers consist largely of starch. Starch has the capacity to turn the brown color of iodine to blue-black because the iodine molecules insert themselves in the structure of the amylose content of the starch.

Foods like steaks, hard-boiled eggs, and chicken are essentially made of proteins and will, therefore, fail the iodine test for starch.

a group of students found the specific gravity of a pice of galena to be 7.8. The accepted value for the specific gravity of galena is 7.2 find the % of error in the student's work

Answers

Answer:

Percent error = 8.3%

Explanation:

Given data:

Accepted value of specific gravity = 7.2

Measured value of specific gravity =  7.8

Percent error = ?

Solution:

Percent error = measured value - accepted value / accepted value × 100

Now we will put the values in formula.

Percent error = 7.8 - 7.2/7.2 × 100

Percent error = 0.6/7.2 × 100

Percent error = 0.083 × 100

Percent error = 8.3%

Answer:

connective: Tissue that supports, protects, and gives structure to other tissues and organs in the body

epithelial: are widespread throughout the body. They form the covering of all body surfaces, line body cavities and hollow organs, and are the major tissue in glands.

muscle: Muscle tissue is composed of cells that have the special ability to shorten or contract in order to produce movement of the body parts. The tissue is highly cellular and is well supplied with blood vessels.

nervous: Nervous tissue is found in the brain, spinal cord, and nerves. It is responsible for coordinating and controlling many body activities.

Explanation:

Answer

Connective tissues gives support, protects and gives structure to other tissues and organs in the body.... example bone, cartilage, blood etc.

Epithelial tissues are spread throughout the body. Their functions include secretion (sweat, mucus), absorption (nutrients) and protection (tissues that lie beneath from radiation) in the body.

In college the GPA of the student is very important and it helps a student obtain good colleges and courses in this regard.

The data collected from college alumni about their careers after college would be the required resource in this case.

What is meant by a research resource?

The kind of research one wants to do and the kind of questions in mind guide the kind of resources required for research. Currently, access to any kind of information for anyone is greater than ever before.

Thus, for good research, it's important to collect data from the right kind of resources. It needs to be located, organized, evaluated, and used for the communication of information.

Various places can be a home for a research resource or be research resources themselves. These can be traditional libraries. Whereas, personal experiences can be important research resources.

Print media, which includes journals, books, brochures, newspapers, and magazines are conventional research resources. Currently, electronic sources found on the Internet are being used. Interviews or surveys can also be considered research resources.

Which are ammonium, ammonia and amide, in order to rank them in terms of how big the angles are, we need their molecular geometry as shown on the attached picture. As you can see, the geometry of ammonium is tetrahedral with an angle between H bonds of 109.5°, the geometry of ammonia is trigonal pyramidal with an angle between H bonds of about 107° and the geometry of amide is bent with angles of 104.5°.

Therefore the order from smallest to biggest is: NH₂⁻<NH₃<NH₄⁺.

Francine is developing a model of the carbon cycle, which involves the movement of carbon among various Earth systems. She begins by drawing the diagram shown below. Her friend Byron evaluates the model, and suggests that she thicken the arrow leading from fossil fuels to the atmosphere. His reasoning is that fossil fuels are being burned at a much faster rate than natural processes are restoring them. If Francine adopts Byron’s suggestion, how could her model be used to explain a significant change to Earth's systems?

Answers

Answer:

After adopting the suggestions of Byron the new or revised model would show that using fossil fuels at a rapid rate would lead to higher inputs of carbon dioxide to the atmosphere which will not be removed by the natural process of removing the excess amount of the carbon dioxide by the process of the photosynthesis and other.

The carbon dioxide would increase due to this and cause trapping of the solar heat in the atmosphere which leads to the greenhouse effect to warm the earth. That ultimately changes the climate of the earth.
