Is RNA always single stranded?
No, RNA is not always single stranded. It can exist as single stranded or double stranded depending on its function and structure.
How do artificial and natural selection contribute to biological diversity?
Artificial selection is controlled by humans and involves selecting specific traits in organisms for breeding, while natural selection is driven by environmental factors. Both processes result in the accumulation of genetic variations over time, contributing to biological diversity by allowing species to adapt and evolve to changing conditions. Artificial selection can be more rapid and targeted, while natural selection is a result of the survival and reproduction of the fittest individuals in a given environment.
Will a dominant allele always increase in frequency over time?
No, a dominant allele will not always increase in frequency over time. The frequency of an allele in a population can be influenced by various factors such as natural selection, genetic drift, and gene flow.
What are two ways in which RNA structure differs from DNA structure?
Chemically RNA and DNA only differ by a single oxygen atom in each nucleotide. Specifically the sugar group in an RNA nucleotide is the sugar ribose, wherease the sugar group in DNA is deoxyribose. Wikipedia has a nice image showing this here: http://en.wikipedia.org/wiki/File:Nucleotides_1.svg Structurally RNA and DNA are also different. DNA exists almost exclusively in a double stranded helix. RNA is typically thought of a single chain that has a far more chaotic structure with the RNA folding back onto itself creating small helical regions where possible. DNA nucleotides contain a different sugar than RNA nucleotides.
Which fruit always travels in groups of two?
Bananas always grow in clusters or pairs, known as "hands," on the banana tree. Each hand typically contains 10 to 20 individual bananas.
The default base is always required in the switch selection structure?
yes,true
How does natural selection contribute to biological evolution?
Selection is not always of the most fit to survive.
When geologists say that a mineral always contains certain elements in definite proportions they mean that the mineral always has what?
When geologists say that a mineral always contains certain elements in definite proportions, they mean that the mineral always has a specific chemical composition. This composition is a key characteristic that helps identify and classify minerals. Minerals are composed of specific elements arranged in a precise crystal lattice structure.
What is the title of the selection?
A, Pepper Always Adds Flavor,
What always contains a?
The alphabet
What is a sentence that has the word structure in it?
There is always a structure to every complete sentence.What is the structure of a paragraph?
Why is it the Darwin theory natural selection is nice?
Nice? The theory of evolution by natural selection is the best and best supported explanation for the fact of evolution we have, but it just is and a word such as " nice " would not always fit theory. Google Ichneumon wasp to see that natural selection is not always " nice. "
Does Data always contains facts true or false?
Data always contains information, but not necessarily facts. Data can be completely made up.
The default base is always required in switch selection structure true or false?
False. The Default section of a switch case section is not mandatory. the programmer can choose to have it if he wants to implement a default functionality in cases where none of the cases match the conditions.

What does the structure of DNA contain?
The structure of DNA contains nucleotides, which are made up of a phosphate group, a sugar molecule (deoxyribose), and a nitrogenous base (adenine, thymine, cytosine, or guanine). The nucleotides are arranged in a double helix formation, with the nitrogenous bases pairing specifically (A with T, C with G) to form the genetic code.
A line always sometimes or never contains at least two points?
always
