Complementary DNA or cDNA is an edited DNA molecule synthesized from a single-stranded RNA called mRNA. The reaction of cDNA formation from mRNA is catalyzed by an enzyme called "reverse transcriptase".
The cDNA strands formed is also known as a complementary copy of mRNA as it contains no introns or non-coding sequence in its sequence similar to mRNA. cDNA is used in recombinant DNA technology to clone eukaryotic genes in prokaryotes.
Thus, option D (they are complementary) is the correct answer.
Staining is an important way to improve what aspects of microscopy?
Answer:
Staining is an important way to improve RESOLUTION AND CONTRAST.
Explanation:
Microscopy refers to the use of microscope. Microscope is a scientific optical instrument that is normally used to achieve in depth study of invisible and very tiny objects. There are many techniques in microscopy, these techniques are use to improve the type of view produce by the microscope.
Staining is one of the techniques that are used in microscopy. It involves adding color to the objects that one wants to view under the microscope. Both living and non living objects can be stained. The major reason for staining is to improve the visualization of the stained object under the microscope. The staining is done in such a way that different important structures will be highlighted.
There are two types of staining, they are simple and differential staining.
Staining enhances contrast and visibility of microscopic specimens, allowing for better observation of cellular structures. It is vital in overcoming light microscopy's limitations in resolution and helps differentiate cell types. Mastery of staining techniques ensures clear and useful microscopic images.
Staining is a fundamental technique in microscopy that significantly enhances the visibility of microscopic specimens. By creating a contrast between the organism and its background, staining allows for better observation and analysis of various cellular structures, sizes, and arrangements. Utilizing stains or dyes can also overcome limitations associated with resolution and contrast in light microscopy. When specimens are properly fixed and stained, they reveal detailed information on cell morphology and can be differentiated according to their unique chemical compositions. Mastery of staining techniques and knowledge of which stains are best suited for each specimen type are crucial for obtaining clear, useful images in microscopy.
For instance, basic staining requires the use of a single dye applied directly to the specimen (direct stain) or used to stain the surrounding area (negative stain), giving a clear image of microbial characteristics. More complex differential staining techniques can be used to differentiate between cell types or cell components and provide further insights into their structures.
Overall, the application of staining techniques in microscopy is vital for achieving the necessary contrast to visualize minute details of microbes and cells. A well-executed stain is critical for proper specimen examination and interpretation in fields such as microbiology and histology.

What does the Hardy-Weinberg principle relate to? A. chances of survival of an organism B. frequency of alleles in a population C. natural selection in a species D. causes of evolution among organisms
Answer: B. frequency of alleles in a population
Explanation:
According to the Hardy–Weinberg principle, both the allele and genotype frequencies in a large, random-mating population will remain constant from generation to generation if no mutation, no gene flow, and no selection occur. They are the key to the importance of the Hardy–Weinberg principle, because individual allele frequencies often change in natural populations, with some alleles becoming more common and others decreasing in frequency. Many factors can alter allele frequencies. Only five, however, alter the proportions of homozygotes and heterozygotes enough to produce significant deviations from the proportions predicted by the Hardy–Weinberg principle: mutation, gene flow, nonrandom mating, genetic drift, and selection.

What condition is required for fermentation to occur? A. When the energy production cycle ends of the Krebs cycle B. When oxygen levels within a cell are too low for aerobic respiration C. When 20 molecules of ATP are needed D. When a glucose molecule needs to break down completely
The condition required for fermentation to occur is when the oxygen levels within a cell are too low for aerobic respiration.
Further Explanation:Cellular respirationThis is the process by which food substances such as glucose are broken down to yield energy in the form of ATP for the cells. The energy is then sued to drive cellular activities such as transport and cell division.Cellular respiration is classified into two;Aerobic respiration.Aerobic respiration is a type of respiration that takes place in living organisms in the presence of oxygen gas. The process involves the breakdown of organic compounds such as glucose to yield energy in the form of ATP and carbon dioxide together with water as byproducts.Anaerobic respiration/Fermentation Anaerobic respiration on the other hand is a type of respiration that occurs in absence of oxygen gas or in presence of low levels of oxygen gas in the cells. It involves the breakdown of organic compounds to form small amount of energy in the form of ATP and ethanol or lactic acid as byproducts.Occurrence.
Aerobic respiration occurs in three stages;
Glycolysis: This is the first stage of aerobic respiration where an organic molecule such as glucose is broken down to form 2 molecules of Acetyl-CoA and net production of 2 ATP molecules. Each glucose molecule yields two molecules of ATP and two molecules of Acetyl-CoA.Kerb's cycle: It is the second phase of aerobic respiration that involves a series of reactions catalyzed by various enzymes. Acetyl-CoA from glycolysis undergoes a series of reaction to produce six molecules of NADH, two molecules of FADH2, together with carbon dioxide and two molecules of ATP.Electron transport chain; This is the final stage of Aerobic respiration, where the six molecules of NADH and two molecules of FADH from Kreb's cycle are used to generate energy in form of ATP. This stage generates 34 molecules of ATP.Anaerobic respiration/Fermentation occurs in two stages;
Glycolysis; One glucose molecule is broken down to pyruvate and two molecules of ATP are formed.Fermentation; This is the second stage of anaerobic respiration, pyruvate from glycolysis can undergo various steps depending on the living organism. It can be converted to ethanol or lactic acid together with carbon dioxide.Keywords: aerobic respiration, anaerobic respiration, Glycolysis, kreb's cycle, Fermentation and Electron transport.

why would two different species have similar features or behaviors?
A.similar DNA
B.similar mutations
C.similar environmental pressures
B. similar mutations
Final answer:
Species can have similar features or behaviors if they face similar environmental pressures leading to convergent evolution or if they have a common evolutionary history indicated by homologous structures. Analogous structures can also occur when species evolve independently to have similar adaptations.
Explanation:
Two different species may have similar features or behaviors due to the convergence of form in organisms that share similar environments, a concept known as convergent evolution. For example, the arctic fox and ptarmigan both have seasonal white phenotypes to blend with the snow and ice. This occurs not due to a common ancestry, but because of similar environmental pressures that offer advantages such as camouflage from predators.
Another reason for similarities might be due to homologous structures, which are features that are similar in form and genetic makeup and indicate a close evolutionary relationship. An example of homologous structures is the similarity in bone structure of bat and bird wings. However, when similarities occur between species that aren't closely related, due to adapting to similar environmental challenges rather than common ancestry, these are referred to as analogous structures or homoplasy. Insect wings vs. bird and bat wings are an example of such analogous structures.

What's one cause of the heat island effect? A. Pollution of groundwater B. Reduced rainfall in urban areas C. Higher albedo in urban areas D. Lower albedo in urban areas
Answer:
D. Lower albedo in urban areas
Explanation:
The heat island effect is caused by several factors, but one of the most important ones is the low albedo. This is particularly the case in the large urban areas. The large urban areas have low albedo, meaning that the solar radiation is accumulated in greater extent, and less of it is reflected back to the atmosphere. This results in an increase of the surface temperature, and the lowest parts of the atmosphere above it. The reason why this happens is that the urban areas are dominated by materials that have low reflection of the solar radiation, such as the concrete and asphalt. The concrete and asphalt are actually absorbing the solar radiation, so the their temperatures is increasing, and since they are the dominant materials, most of the area has rise in the temperatures. In practice this can easily be noticed by the people, as if the weather is warmer, in larger urban area it feels like we are in an oven, with heat surrounding us from all sides.
