Taxonomy

The Radio-ulna and digits of most primates and animals represents a homologous structure




An example of another internal structure is the genes.
The homologous chromosomes have the same genes in common. Each cell has at least two sets of chromosomes which one comes from one’s father also called as paternal chromosome and mother, called as the maternal chromosomes. These chromosomes are what makes the child obtain the characters and may depend on the traits the parents possess. Homologous chromosomes are not duplicated chromosomes or identical however, they are analogous or similar. The alleles for a specific characteristics isn’t the same but the same genes are in the same order.<span> </span>

Respiration is a process where many chemical bonds inside the body break and release energy. This energy is used to perform vari
dangina [55]

Answer:

The  correct answer is chemical energy from broken bonds is transformed into mechanical energy.

Explanation:

Muscle contraction need energy in form of ATP.ATP contain 2 high energized phosphoanhydride bonds.

                  The hydrolysis of phosphoanhydride bonds releases chemical energy which is transformed into mechanical energy for helping the muscles to move.

Based on the definitions of pharmacophore and privileged structure, outline essential structural features a 1,4-dihyrdopyridine
stiv31 [10]

Answer:

Explanation:

Pharmacophore (pharmacology) - The molecular framework responsible for a drug's biological activity. According to IUPAC — A pharmacophore is the ensemble of steric and electronic features that is necessary to ensure the optimal supramolecular interactions with a specific biological target structure and to trigger (or to block) its biological response.

Privileged structures are defined as molecular frameworks which are able of providing useful ligands for more than one type of receptor or enzyme target by judicious structural modifications.

1) The 1,4-dihydropyridine ring is present in many biologically important molecules that acts as an important scaffold for cardiovascular drug - a calcium antagonists and although it is technically not considered as a pharmacophore, it is considered as a privileged structure.

1,4-Dihydropyridine (DHP), belongs to the class of calcium antagonist that inhibits the influx of extracellular Ca+2 through the L-type voltage-dependent calcium channels.

A positional substitution in the 4-position is feasible in the heterocyclic ring which in turn culminates in various calcium channel antagonist activities and this heterocyclic ring is the common feature for various pharmacological activities such as anti-inflammatory activity, analgesic activity,

antihypertensive, antianginal, antitumor, antitubercular activity and antithrombotic .

Position on the heterocyclic ring binds to the L-type channel and also to N-type channel on membranes.

2.) The bioisosteres are not a suitable bioisostere for the traditional C-4 aryl or heteroaryl substitution which is necessary for calcium ion blockage thereby inhibiting it to function with the mechanism shared above.
