Answer:
A. Benedict test
Explanation:
Orange juice is acidic in nature. The test which would show positive results for orange juice is Benedict test, i.e. option A.
A chemical test called Benedict's test can be performed to determine if an analyte contains reducing sugars. This test can thus be used to identify simple carbohydrates that have a free ketone or aldehyde functional group. The test is based on a compound combination of sodium citrate, sodium carbonate, and the pentahydrate of copper(II) sulfate known as Benedict's reagent, also referred to as Benedict's solution.
Therefore, Benedict test can be done to check for orange juice. The correct answer is option A.

What is denaturation? What are some things that can cause this to happen?
Answer:
If a protein loses its shape, it ceases to perform that function. The process that causes a protein to lose its shape is known as denaturation. Denaturation is usually caused by external stress on the protein, such as solvents, inorganic salts, exposure to acids or bases, and heat.

By the 1950s, there was Choose... major variety(ies) of banana being grown commercially in the world. Then, a soil fungus called Fusarium struck the banana plants, causing Panama Disease. Because of Choose... , the bananas could not resist the fungus. Within a few years, the entire commercial banana industry had collapsed. The industry switched to a different kind of banana. Yet fifty years later, Panama Disease has returned, and there is still no cure for it. Scientists argue that the best solution for the future is Choose... .
Answer:
Produce resistance variety or use of fungicides.
Explanation:
The best solution for the future is to produce resistance variety to Panama Disease or fungicide spray that kills Fusarium fungus that causes Panama Disease. If the variety is resistance against Fusarium fungus so they get no adverse affect from it. The use of chemical that kills Fusarium fungus is also a good method to protect banana industry from the adverse effect of this disease.

Jorge is drawing an atomic model. The part of the atom that he has drawn is shown below. What does Jorge need to add to complete his atomic model?
Answer:
An atom is the smallest particle in a chemical element that holds its chemical properties. Although in the past it was thought impossible to break an atom, within modern chemistry we know that an atom is composed of subatomic particles, which compose the atomic model:
1) electrons, which have a negative charge, such a small size that it is immeasurable, and a mass much smaller than the other two subatomic particles; 2) protons, which have a positive charge; and 3) neutrons, which have no charge.
The protons and neutrons form a dense and massive atomic nucleus, which is called multipons nuclei. The electrons form a cloud of electrons that surround the nucleus.

A tumor is:
a) a large group of cells that grew without regulation
b) a large group of cells that is growing a new structure
c) a group of cells that is a different type than what surrounds it
As a cell grows it’s Increase more than it’s.
Answer:
volume
surface area
Explanation:
The growth of the cell includes the increase in the mass of the cell by the absorption of nutrients and elimination of the wastes. This process helps the cell to grow in size. In this process, the volume of the cell increases faster than the surface area. This gradually leads to the decrease in the surface area of the cell. The increase in the volume expands the cell membrane also.

Investigation of HOX genes indicates that the animal family tree" can be simplified to only how many different types of animals?
Answer:
three evolutionary lines
Explanation:
The Hox genes are master developmental genes found in animals, which are involved in the regulation of development by specifying the body plan of an embryo along the head-tail axis. Recently, several research groups studied the assortment of the Hox genes in three different marine organisms: 1- a priapulid worm (an unsegmented marine worm), 2- a brachiopod (phylum Brachiopoda), and 3- a polychaete worm (related to earthworms). Then, these research groups combined their research efforts to compare the assortment of the Hox genes observed in these species to those observed in previously studied animals including, among others, mice, fruit flies and sea urchins. From this combined study, researchers concluded that the animal kingdom can be divided into three primary evolutionary lineages.

Using indoor tanning bed before the age of 35 can increase your risk of melanoma, the deadliest form of skin cancer, by 59 percent. The risk increases with each use. Research demonstrates that even people who do not burn after indoor tanning or sun exposure are at an increased risk of melanoma if they tan indoors; therefore, exposure to the radiation emitted by tanning beds can cause skin cancer. This cancer is the direct result of a:
a) mutation in a protein
b) mutation in the genetic material
c) change in fat molecule
d) change in a starch molecule
Answer: mutation in the genetic material
Explanation: just took the test and got it right
This cancer is the direct result of a mutation in the genetic material.
What is Mutation?Genetic mutations, which occur as your cells divide and generate duplicates of themselves, are modifications to your DNA sequence. Your DNA teaches your body how to develop and work.
Genetic changes may result in diseases like cancer or, in the long run, may enable people to adapt to their environment more successfully.
A change in the DNA sequence is referred to as a genetic mutation. Your cells receive the information they require to carry out their functions from your DNA sequence.
Therefore, This cancer is the direct result of a mutation in the genetic material.
