A medical researcher is investigating the chemical and physical properties of substance that she isolated from the surface of ch

arcoal-grilled meat. When the scientist mixes a small amount of the substance with living human cells, the chemical causes the rapid breakdown of the cells' plasma membranes. She is able to prevent this reaction by adding vitamin C to the mixture of the substance chemical and cells. Based on this information, the scientist has

Answer:

the scientist has determined that the chemical isolated from charcoal-grilled meat is an oxidant.

Explanation:

oxidants are oxidizing agents. oxidants have the capacity to damaging living cells. vitamin C on the other hand is an active antioxidant, hence it was able the breakdown of the cells.

You believe that the cytosolic protein p007 is involved in mediating growth hormone-stimulated proliferation in cells. You wish
Zinaida [17]

Answer:

Following are the answer to this question:

Explanation:

In option a:

There are many ways, which can be defined as follows:  

  • It keeping cells "qualified," use heat shock and handle ions like Ca and ice incubating.
  • It uses Micro-injection with DNA.  
  • It uses the biolistics or even the process of gene-gun.  

The stable cell charts indicate simple and definitive outcomes when their relationship to specific results. Moreover, relative to temporary cell lines, findings are more reliable and error-free. These lines also easily break and much less.

In option b:

Radio tests including linking tests could be used  

The Ligand Binding Assays is an analysis, that is based on the binding of ligands to antibodies, or other macromolecules. Its existence and distance of formed ligand-receptor complexes are defined using a system of measurement that is usually electrical or fluorescent.

In option c:

The method for measuring the levels of cell growth is accessible and the  Another way is to measure the metabolism within the same cell. So many color pigments were also accessible that can permeate an organism as well as react with some proteins as well as other factors, and that can effectively identify a color final product.  

Throughout relation to the amount of metabolism exercise, cell proliferation could be evaluated by researching one or even more cell markings. The BrdU limited liability assessment is a very well-published illustration.  

Its specific antibody can detect BrdU and high BrdUincorporations levels are linked to high levels of cell proliferation.  Command cell without DNA receptor growth hormone.

In option d:

The cell growth will stop after each use of RNA interference ( RNAi). The p007 formation as well as the effect on growth caused by the intrusion will be a goal. If development is delayed effectively, the theory will be tested successfully to a cell without any of the required DNA. The RNAi is the free cell

In a particular human family, John and his mother both have brachydactyly (a rare autosomal dominant allele causing short finger
Luba_88 [7]

Answer:

Brachydactyly and Huntington are phenotypic diseases that develop when a person has one or two dominant alleles for these traits.

John's father has the Huntington disease, but not brachydactyly so his genotype is Hh/bb.

John's mother is a healthy women with brachydactyly, so her's genotype is probably hh/BB or hh/Bb.

Fudgin [204]
<h2>Material Do Alice and Julio Likely Work - Option B</h2>

Alice and Julio’s company makes protective coverings for off-roading vehicles. Alice’s job involves harvesting a natural polymer from trees. Julio’s job is to take that material and change it chemically to create a synthetic polymer.

Alice and Julio most likely work with natural rubber and vulcanized rubber. Alice works with natural rubber, and Julio works with vulcanized rubber.
