Mary received a flu vaccine. Why didn't the vaccine make her sick?
Mary didn't get sick from the flu vaccine because it contains the smaller portion of the flu which isn't strong enough to infect you. Moreover, your white blood cells attack the portion of the flu while the memory cells take note of the flu, so when it comes next time, it won't affect your body because it knows how to fight the virus.
Hope this helps!
Plz help me.!!!!!!!!!!!!!!!!
You have purified the receptor for a hormone by affinity chromatography. During gel filtration chromatography under native conditions the receptor elutes between pyruvate decarboxylase (250 kDa) and glutamine synthetase (620 kDa). During SDS-PAGE, in the absence of reducing agents, the receptor migrates as a single band of approximately 230 kDa. When SDS-PAGE is carried out in the presence of 2-mercaptoethanol the receptor migrates as two bands of approximately 95 and 135 kDa. Explain this result.
Answer:
the hormone receptor is a heterotetramer composed of two subunits with 95 kDa and two subunits with 135 kDa
Explanation:
In this case, the heterotetramer is composed of two heterodimers, each composed of two subunits that held together by disulfide bonds. These heterodimers bind together through hydrophobic interactions in order to form a tetramer. The Sodium Dodecyl Sulfate (SDS) is a denaturing detergent that dissociates both heterodimers by interfering with hydrophobic interactions that hold heterodimers together. It is for that reason that only a single band of 230 kDa is observed (135 kDa + 95 kDa = 230 kDa). Moreover, 2-Mercaptoethanol breaks disulfide bonds, thereby separating the two subunits in the heterodimer. In consequence, after the use of this chemical compound (2-Mercaptoethanol), two different bands with 135 kDa and 95 kDa can be observed.

If the amount of glucose is increased for an animal so what will happen
Answer:
In normal course, excess glucose gets stored in the liver as glycogen and if the levels are more it gets converted into fat and gets stored in liver as well as in adipose tissues. A primary role for the glucose molecule is to act as a source of energy; a fuel. Plants and animals use glucose as a soluble, easily distributed form of chemical energy which can be 'burnt' in the cytoplasm and mitochondria to release carbon dioxide, water and energy.

how to read a scientific paper? and use a publication to demonstrate the different steps? pleas help me
Answer:
Attempting to read a scientific article for the first time may seem overwhelming and confusing. This guide details how to read a scientific article step-by-step. First, you should not approach a scientific article like a textbook— reading from beginning to end of the chapter or book without pause for reflection or criticism. Reading and understanding research papers is a skill that every single doctor and scientist has had to learn during graduate school. You can learn it too, but like any skill it takes patience and practice. Reading a scientific paper is a completely different process from reading an article about science in a blog or newspaper.

Explanation:
The growth patterns of plants such as ivy and pole beans are regulated by
A.) phototropism
B.)thigmotropism
C.)all of the above
Answer:
The correct answer is - C) all of the above.
Explanation:
The growth patterns of the plants such as ivy and pole beans depend and controlled by various physiological processes. These physiological process helps in the plants to grow in a particular direction so they can get nutrition and resources they require for their growth and development.
These processes are Gravitropism, phototropism, and thigmotropism. Gravitropism ensures that plant roots grow towards the soil so they can get water and other nutrients. Phototropism is the other process that allows the plant to move in the direction of the light so they can get enough light for the photosynthesis process. Thigmotropism is the process or defense mechanism that and movement by touch stimulus.
An experiment was done by Gierer and Schramm where they exposed plant tissue to purified RNA from tobacco mosaic virus, and the plants developed the same types of lesions as if they had been exposed to the virus itself. After checking relevant websites, what would you suggest would their results be if the RNA is treated with DNase, RNase, or protease prior to its exposure to the plant tissue
Answer:
See the answer below
Explanation:
A DNase is also known as deoxyribonuclease and it is an enzyme that catalyzes the degradation of deoxyribonucleic acid by cleaving the phosphodiester linkage in their structures. Thus, if the RNA is treated with a DNase before the plants are exposed to it, it will not make any difference. The plants will develop the same types of lesions as if they have been exposed to the mosaic virus.
Unlike DNase, RNase is a ribonuclease, an enzyme that is capable of carrying out catalytic degradation of ribonucleic acids. This means that if the RNA is treated with RNase before the plants are made to be exposed to it, they will not develop the lesions because the RNA would have been degraded by the enzyme.
A protease is an enzyme that degrades the structure of proteins. Treating a RNA with protease will thus have no effect on the structure of the RNA. Exposing the plants to the protease-treated RNA will make no difference. The plants will still come down with the lesions as if they have been exposed to the virus.

How many alleles are typically present in a genotype?
Answer:A genotype is the combination of two alleles, one received from each parent. The expression of a genotype is called the phenotype and the specific combination of the two alleles (the genotype) influences the physical expression (the phenotype) of the physical trait that the alleles carry information for.
