Answer:
1= In living organisms cells are composed of water or we can say that water is one of the important constituent of cells.
2= Hydrogen bonding import man properties to the water such as cohesion, high heat of vaporization, high heat capacity etc.
3= Because of high polarity, all polar substance get dissolve and make it universal solvent.
Explanation:
Solvent is the that part of solution which is present in large proportion and have ability to dissolve the solute. In simplest form it is something in which other substance get dissolve. The most widely used solvent is water, other examples are toluene, acetone, ethanol, chloroform etc.
Water is called universal solvent because of high polarity all polar substance are dissolve in it. Hydrogen is less electronegative while oxygen is more electronegative and because of difference in electronegativity hydrogen carry the partial positive charge while oxygen carry partial negative charge.
Hydrogen bond:
The hydrogen bond is the attraction between the toms which already take part in the other chemical bons. The one atom is hydrogen while other may be oxygen, nitrogen or fluorine.
The hydrogen bonding in water import man y properties in it such cohesion, high heat of vaporization, high heat capacity etc. The hydrogen bond hold the water molecules together.
Water create electrostatic interaction with other polar molecules. The negative end of water attract the positive end of polar molecules and positive end of water attract negative end of polar substance and in this way polar substance get dissolve in it.
Example:
when we stir the sodium chloride into water the cation Na⁺ ions are surrounded by the negative end of water i.e oxygen and anion Cl⁻ is surrounded by the positive end of water i.e hydrogen and in this way all salt is get dissolved.
Cephalopoda
Explanation:
Cephalopods are commonly known as inkfishes.
But cephalopods are not at all fishes. They are molluscs.
They belong to Class Cephalopoda of phylum Mollusca.
Like other molluscs, these are also soft bodied, but have a series of tentacles that actually developed from theprimitive foot.
Cephalopods have a well developed nervous system and have large bulging eyes.
Examples of cephalopods are, octopus, giant squid etc.
Considering all the above characteristics, we can conclude that the predator stated in the question is most likely to belong to the clade cephalopoda.
The purpose of vesicles is simply water retention
I believe the correct answer to the question is D. This answer choice makes the most sense given the context. Also, since RNA is less stable than DNA, it mutates more often.
Answer:
Yes.
Explanation:
Cell division & differentiation also happens in animals and plants, and is not limited to just human beings.
