explain why it is important to keep the levels of nucleotides relatively balanced in the context of dna and rna synthesis

juin [17]

Answer:

Read Below

Explanation:

Nucleotides are A & T and G&C you see in DNA and in RNA T is Replaced by U. The reason they must be balanced between G&C and T&A is because G has to bond with A in DNA and G with C so if there is more G than C that means there is mismatches between the DNA nucleotides same thing for A and T. In RNA you follow the same rule. If we have lets say 27% of our DNA as A we have to have 27% as T leaving 23% as C and 23% as G. If there was lets say 29% T while one 27% A then there was a error in DNA replication and could lead to errors in RNA synthesis if not corrected

which classification level is broader than the kingdom level; which branch of biology is concerned with the naming and classifyi

shtirl [24]

Domain is broader than the kingdom level.

Levels of classification that are broader than phylum are regions and kingdoms. There are five kingdoms: Monrea, Protista, Fungi, Plants.

Taxanomy is the branch of biology concerned with the naming and classifying of organisms.

Protists are described as diverse organisms because they have many different characteristics. They are either heterotrophs or autotrophs. They are also eukaryotes that are not classified as plants, animals or fungi.

Animals group of organisms includes only multicellular heterotrophs.

If two species belong to the same class, they also belong to the same taxon higher up in the hierarchy. Here they belong to the same side and kingdom.

The gradual change in a species over time is called Evolution.

The levels of classification that are broader than the phylum are domains and kingdoms.

Taxonomy is the science of naming, describing and classifying all living organisms, including plants.

The locations of neural activity, called _____, are interconnected.

Usimov [2.4K]

Nodes
<span>
Sensory neurons are the neurons responsible for receiving the information from the environment or the stimuli. This sensory neurons pass the message thru interneurons and then to Central Nervous System (brain and spinal cord) which then sends the signal to the motor neuron. </span>

Show a diagram of how ions are formed when a sodium atom comes into close

Firdavs [7]

Answer:

The diagram is attached below.

Explanation:

when sodium and chlorine comes close together they form anion and cation. The compound formed is called sodium chloride.

Both atoms bonded together through ionic bond.

Ionic bond:

It is the bond which is formed by the transfer of electron from one atom to the atom of another element.

Both bonded atoms have very large electronegativity difference. The atom with large electronegativity value accept the electron from other with smaller value of electronegativity.

For example:

Sodium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion.
