What is a DNA probe?
Answer:
In molecular biology, a hybridization probe is a fragment of DNA or RNA of variable length which can be radioactively or fluorescently labeled. It can then be used in DNA or RNA samples to detect the presence of nucleotide substances that are complementary to the sequence in the probe.DNA probes are stretches of single-stranded DNA used to detect the presence of complementary nucleic acid sequences (target sequences) by hybridization. DNA probes are usually labelled, for example with radioisotopes, epitopes, biotin or fluorophores to enable their detection.
spanish
En biología molecular, una sonda de hibridación es un fragmento de ADN o ARN de longitud variable que puede marcarse de forma radiactiva o fluorescente. Luego puede usarse en muestras de ADN o ARN para detectar la presencia de sustancias nucleotídicas que son complementarias a la secuencia en la sonda. Las sondas de ADN son tramos de ADN monocatenario utilizados para detectar la presencia de secuencias complementarias de ácido nucleico (secuencias diana) por hibridación Las sondas de ADN generalmente están marcadas, por ejemplo, con radioisótopos, epítopos, biotina o fluoróforos para permitir su detección.

Which of the following terms describes a lipid molecule that has only single
bonds between its carbon atoms?
Answer:
Saturated fatty acids have only single bonds between carbon atoms. As a result, the carbon atoms are bonded to as many hydrogen atoms as possible. In other words, the carbon atoms are saturated with hydrogens. Saturated fatty acids are found in fats.

A student is given five samples and told they are lysine (an amino acid), lactose (a disaccharide), insulin (a protein hormone), RNA and fat. The samples are in test tubes marked 1-5, but the student doesn't know which compound is in which tube. The student is instructed to identify the contents of each tube. Base on these data, identify what is in each tube. In her first test, she tries to hydrolyze a portion of the contents of each tube. Hydrolysis occurs in all tubes except tube 3. In the next test, she finds that tubes 1, 2, and 3 are positive for nitrogen but only tube 2 gives a positive result for the presence of sulfur. In the next test the student shows that the compound in tube 1 contains a high percentage of phosphate. In the final test the student shows that compound 5 is hydrophobic. Base on these data, identify what is in each tube. 1 2 3 4 5 A. lactose B. RNA C. lysine D. fat
Answer:
1. RNA 2. Insulin 3. Lysine 4. Lactose 5. Fat
Explanation:
RNA contains both nitrogen and phosphate hence it is the substance in tube 1.
Insulin being a protein contains sulfur hence it is the substance in tube 2.
Lysine does not hydrolyse hence it is the substance in tube 3.
Fat is hydrophobic hence it is the substance in tube 5.
Since lactose does hydrolyse and because the rest have been identified, it must be the substance in tube 4.
Based on these data, each tube is identified as:
tube 1: RNAtube 2: Insulintube 3: Lysinetube 4: Lactosetube 5: Fat1. first testHydrolysis doesn't occur in lysine so, the 3rd tube contains lysine.
2. second testNitrogen is present in Insulin(in amino acids), RNA(in nucleotides), and Lysine. Insulin consists of two polypeptide chains (A and B) which are joined by sulfur bonds. So, 2nd tube contains insulin.
3. third testIn RNA, nucleotides are present which consists of phosphate groups. Adjacent nucleotides are joined together by phosphodiester bonds. So, 1st tube contains RNA
5. 4th testFatty acids are Hydrophobic due to the presence of long hydrocarbon chains. So, 5th tube contains Fat.

What is the difference between native and nonnative species
Answer:
Native plants are those plants which occur naturally in a region. A non-native is one that does not.
Explanation:
For example, soybeans, kiwi fruit, wheat, honey bees, and all livestock except the American bison and the turkey are non-native species to North America.
Answer:
Native species are naturally present in an area. ... Non-native species do not cause environmental or economic harm. An important, not-to-be-missed distinction between non-native species and invasive species is that non-native species do not disrupt the natural functions and processes of our native ecosystems.

what chemical substances must be provided for aerobic respiration to take place inside the cell
Answer:
Oxygen
Explanation:
Cellular respiration can occur both aerobically (using oxygen), or anaerobically (without oxygen). During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts. In cellular respiration, glucose and oxygen react to form ATP.

Populations are greater in fertile areas that are close to freshwater sources, which is why more people live near mountains.
Populations are greater in fertile areas that are close to freshwater sources, which is why more people live near rivers.
Answer:
D. Populations are greater in fertile areas that are close to freshwater sources, which is why more people live near rivers.
Explanation:
Population is greatly depend on the availability of water. Those areas are densely populated areas where water is present in sufficient quantity as compared to those areas have low population density where water is in low amount. The main reason is that water plays a vital role in our daily life which is used almost in every aspects of life. We can see that deserts have less population due to less water availability and areas attached to the rivers are densely populated due to more water availability.

A recent encyclopedia entry about dogs cites multiple research papers done by scientists at veterinary schools. According to the article, Labrador retrievers come in two specific breeds: English and American. The English breed is described as stocky and heavy, while the American breed is described as tall and lanky. The article describes current scientific research as showing that males of both breeds usually weigh about 29-41 kg (65-90 lb), and females weigh 25-32 kg (55-70 lb). Coat colors for both breeds come in solid black, yellow, or chocolate. All labs have strong tails and webbed feet, which help them swim. Devon would like to use this information to determine if his new dog is an English or American Labrador retriever.
Which best describes the reliability of the information?
It is not reliable because only scientists can use scientific information for reference.
It is not reliable because it doesn’t talk about how to test and only gives data about the breeds.
It is reliable because the article is based on multiple studies done by scientists at multiple veterinary schools.
It is reliable because it gives information about both types of Labradors in addition to information about other types of dogs.
Answer:
It is reliable because the article is based on multiple studies done by scientists at multiple veterinary schools.
Explanation:
The information in the article can be described as reliable due to the fact that it is based on multiple studies by scientists.
When a study is carried out by different group of independent researchers and a similar result if obtained, the results becomes more or less a theory. A research that is reproducible and gives similar result can totally be relied on for information.
