Cyclopropane is a highly strained molecule because the conformations of the cycloalkanes are influenced by the torsional, angle strain, and steric strain. Cycloalkanes, which comprises more than three atoms of carbons are not flat molecules, they are puckered.
The three and four-membered ring components exhibit angle strain and minimize the internal bond angles. The angle strain is generated when the bond angles deviate from the optimum tetrahedral angle, that is, 109.5 degree.
Torsional strain is a resultant of eclipsing interactions, and steric strain is attained when the atoms are forced too close to each other.
Answer:
The diagram represents a plant leaf cell and two different molecules used in the process of glucose synthesis. ... The arrows in the diagram indicate the movement of molecules of oxygen and water into the cell.
Explanation:
The question is incomplete as it does not have the tiles which has been presented in the attachment.
Explanation:
Natural selection is the mechanism by which the species evolve. The species evolve under the influence of the natural pressure due to which the species try to hit and trial method of the adaptive trait. The trait which increases the fitness of a species is passed on to the next generation and the trait becomes established in a population.
This can be observed in the following scenario
1. The hawks predate on the rabbit species with white fur easily as they can be seen from the sky easily.
2. This acts as a pressure on the white rabbits as a result of which the white rabbits to hide themselves mutate and change the colour of the fur from white to brown or tan.
3. The founder effect will eliminate the white fur population from the whole population
4. The population with brown fur will increase with time and the trait will become a permanent trait.
Unlike-classical conditioning, operant conditioning requires the organism to voluntarily produce the-response
