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.
The common name of this organism is hydra.
<u>Explanation:</u>
Hydra is a fresh water organism and belongs to the phylum Cnidarian. They have tentacles around their body that enables locomotion as well as protection from prey. Hydra has the ability of regeneration and the asexual mode of reproduction in hydra is budding.
In the budding process, a small bud develops in the parent body and the bud after maturation gets detached from the parent body and grows into a new individual. Sexual mode of reproduction is also found in hydra.
Answer:
<h2>1. DdBb</h2><h2>2. ddBb</h2><h2>3. DB, Db, dB and db.</h2><h2>4. dB and db.</h2><h2>5 50% or 1/2</h2><h2>6. 1/8 </h2>
Explanation:
As given, Allele for dimples(D) is dominant over alleles for no dimples (d), so D is dominant over d.
Allele for broad eyebrows (B) is dominant over allele for slender eyebrows (b), so B is dominant over b.
A man heterozygous for both traits ( DdBb) marries a women who has no dimple and heterozygous fro eyebrow (ddBb)
So cross is = DdBb × ddBb
1). Genotype of the man is DdBb.
2). Genotype of the woman is ddBb.
3). Genotype of the gametes produced by the man are DB, Db, dB and db.
4). Genotype of the gametes produced by the woman are dB and db.
5). Probability that their first child will have dimples 50% or 1/2
6). Probability that there first child will have both dimples as well as slender eyebrows 1/8
H20 tends to evaporate quicker in 80 degrees or higher, evaporation in colder weather, is much slower.
