It is found that more than beta dicarbonyl compounds have more than 75 % concentration in Enol form and remaining in Keto form.
Reason: This excess of Enol form can be explained due to extra stability of this isomer. It is found that the enol form is being stabilized by the interamolecular interactions i.e. Hydrogen bonding between the hydroxyl group (acting as Hydrogen Bond Donor) and Carbonyl Oxygen (Hydrogen Bond Acceptor).
The cell membrane lets substances come in and out of the cell. This is found in plant and animal cells. The cell wall acts like a barrier or a wall for the cell, and this is only found in a plant cell. The nucleus is basically the 'brain' of the cell. This is found in both plant and animal cells. It is only found in eukaryotes. The cytoplasm is a gel-like fluid that fills up the cell.
Answer:
Black
Explanation:
The color of an object is the color that it does not absorb.
The piece of paper absorbs all colors in the seven colors that make the white color; therefore, its color has to be black.
Answer:
<em>The water vascular system of echinoderms </em><em>functions in locomotion and feeding</em>.
Explanation:
Echinoderms have a unique vascular aquatic system called the <u>ambulacral system. </u>
The ambulacral system refers to a net of fluid-filled channels derived from the coelom with functions related to gas exchange, feeding, stimuli reception, and locomotion. This system acts as a hydro motor apparatus.
The opening to the exterior of this vascular system is through an opening known as madreporite. This structure is united to the circular channel that surrounds the animal´s mouth and from where five radial channels emerge and extend along each arm. Water runs through these structures and makes it possible the gas exchange, feeding, locomotion, and other functions. By hydrostatic pressure, little tubular feet are protruded and retracted and help the animal to move.
