The group of choices is as follow:

A. RNA polymerase are added to the PCR mix to design random primers  

B. If detecting viral infection by PCR, the primers must not be complimentary (match) to regions of human DNA  

C. Pairs of primers must be designed, one to start amplification with Taq polymerase, the other to start amplification with human polymerase  

D. Primers are optional if you want to amplify all DNA within a sample

Answer:

The correct answer is - B. If detecting viral infection by PCR, the primers must be complementary to regions of human DNA.

Explanation:

Short, single-stranded segments of DNA sequences utilize in the real-time PCR or polymerase chain reaction technique are called primers. Primers used to hybridize the region of the segment needed to be amplified.

The human polymerase enzyme is not used in the PCR reaction and requires a 3'OH group to synthesize the DNA by amplification which is possible only in the presence of primers as they have a 3'OH.

Answer:

A disease that causes cells to grow too rapidly

Explanation:

The cancer has spread to another part of the body where there originally wasn't any cancer. Ex: If someone was diagnosed with thyroid cancer and then later they're told the cancer has spread to their lungs

Cancer  is characterized by abnormal cell growth when a cell does not divide naturally, it is said to have metastasized, which means that the cancer has spread from one part of the body to another.

It is a type of condition where the person's normal cell growth is hampered, and it has a significant impact on an individual, leading to a wide range of symptoms such as pain and fatigue and increasing mental health issues and an example of metastasis is the brain cancer can move to the lungs and other parts. Due to the significant advancements in the diagnosis and treatment of cancer, an earlier stage can be detected and the later stage can be somewhat cured.

Hence, cancer is characterized by abnormal cell growth when a cell does not divide naturally, it is said to have metastasized, which means that the cancer has spread from one part of the body to another.

Answer:

The scientific process is important when learning about diseases because it allows to obtain reliable and valid knowledge about the different existing diseases, it helps in solving problems correctly and it is the best tool to nullify arbitrary opinions regarding a diagnosis or treatment, taking into account each of its stages.

Explanation:

The scientific method is a process through which relationships between facts are established to arrive at the verification of something. Through this step by step in which facts are discarded and added, the answers to findings are based. It is through the information generated by the research that it is possible to associate and / or integrate a set of symptoms and signs with a probable nosological diagnosis. Similarly, the selection of treatment and even the prognosis of patients depend on the information obtained from a population of subjects who share attributes; they depend, in a word, on research. Bearing in mind the scientific process, scientific thinking develops with practice, and for this it is necessary that there be constant reflection on the problems, have guides for the interpretation of medical reading, develop research protocols, learn to collect and analyze data about diseases.

Scientific is very important in order to obtain information about the disease.

The scientific process is important when learning about diseases because it provides information about various aspects of diseases as well as provides solution about cure of the disease.

This scientific process or method can be used for obtaining information about the causes of disease, its causing agents and cure for the disease so we can conclude that scientific is very important in order to obtain information about the disease.

The tool which is typically used for testing nitrates is: C. soil testing kit

Nitrogen is a chemical element with the symbol "N" and it has an atomic number (number of protons) of 7.

Basically, nitrogen is found in group (5) of the periodic table and as such it has 5 electrons in its outermost shell.

Oxygen is a chemical element with the symbol "O" and it has an atomic number (number of protons) of 8.

Generally, when nitrogen and oxygen react chemically, they produce a compound known as nitrogen dioxide.

In Chemistry, nitrates are chemical compound that comprises nitrogen and oxygen.

Also, nitrates are used in the production of soil fertilizers in agriculture.

In conclusion, a soil testing kit is mainly used to test the presence of nutrients such as nitrates in soils.

Answer:

A forest ecosystem is more stable than a potato field.

Explanation:

The forest ecosystem is a natural one and all the elements are balanced, they are managed by the nature itself.

The forest ecosystem is a natural one, and all the components are in harmony since nature herself manages the ecosystem.

Thus, A forest ecosystem, or simply a forest, is a community of plants, animals, microorganisms, and other species that interact with the chemical and physical elements of their environment.

The species in a forest ecosystem are depending on one another in order to survive, and they can be roughly categorized as producers, consumers, and decomposers based on their ecological roles.

The boreal forest that surrounds the Earth in northern latitudes is an example of a vast forest ecosystem. A forest ecosystem can also be as small as a microsite on a tree limb where mosses, insects, and microscopic species coexist.

Thus, The forest ecosystem is a natural one, and all the components are in harmony since nature herself manages the ecosystem.

Answer:

fishes

Explanation:

A progenitor feature found in early boney fish served as the basis for the development of the vertebrate lung.

The lung of modern vertebrates evolved from a structure that was present in the ancestors of early boney fish.

Lungs in vertebrates originated as extra air-breathing organs in primordial fishes and were ventilated by buccal pumping when they first appeared. In more modern fishes, the organ formerly known as the lungs has been replaced with the hydrostatic swimbladder. This fundamental kind of unicameral lungs and the buccal pumping ventilation observed in these lungs can also be found in more modern amphibians.

C) hearing

D) sight

The correct answer to the question is option D

SIGHT.

If one is experiencing Na channels deactivating the plasma membrane,the sense that is being activated is SIGHT,

this is because in the red blood cell,the light induced isomerization of the moiety retinal rhodoesin produce activated opsin which goes ahead to activate the signal transducing G-protein transducin,this it does by catalyzing exchange of GTP (Guanosine triphosphate) for bound GDP(guanosine diphosphate) on the subunit.

This GTP in turn activates the level of CGMP (Cyclic guanosine monophosphate) phosphodiesterase and it further acts to lower the level of CGMP.

Upon this reduction,it leads to the closing of CGMP-gated Na+ channels and hyperpolarization of the membrane.

Answer:

Some important constraints:  

-Plant breeding: autogamy and allogamy, self-sterility, etc  

-Animal breeding:  trait compatibility

- Breeding systems in general (i.e., both in plants and animals): barriers for sexual reproduction  

Explanation:

Crossbreeding systems consist of the breeding between two breeds in order to develop progeny with particular advantageous phenotypic traits. In-plant crossbreeding systems, it is imperative to have into account whether the plant is autogamous (reproducing by self-pollination) or allogamous (reproducing by cross-fertilization), because it will affect the fitness of the progeny resulting from these breeds. Moreover, the biological mechanisms of self sterility and compatibility must be also taken into consideration. In-animal breeding systems, it is important to have into consideration that phenotypic traits we desire to obtain in the progeny must be compatible between races. In addition, the barriers for sexual reproduction are also an important issue both in plant and animal breeding systems, it thus being impossible, for example, to get a breeding between Chihuahua and Great Dane dogs.
