B.) Cohesion
Explanation:
The best term that fits the description of the term surface tension of water is cohesion.
Cohesion is the intermolecular forces that holds together the particles of liquids and solids.
- Surface tension is a phenomenon in liquids that causes them to come together more and shrink on the surface.
- Surface tension is made possible by cohesive forces between water- water molecules.
- Adhesion is between different molecules like water and glass.
- In capillary action, a liquid is able to rise up in a column
- Sublimation is a phase change from solid to gas.

Answer:
1/3
Explanation:
<em>A standard monohybrid cross is a cross that follows the dominance/recessive pattern from Mendel's experiment.</em>
It means the purple flower color is dominant over the white flower color.
Assuming the allele for purple flower color is P and that of the white flower color is p, a standard monohybrid cross will involve a true breeding PP and pp.
PP x pp: Pp, Pp, Pp and Pp. All the F1 offspring will have purple flowers with Pp genotype.
At F2: Pp x Pp = PP, Pp, Pp, and pp.
3/4 or 75% of the F2 offspring have purple flower color out of which 1 is true breeding for the trait.
Hence the fraction of the purple flowered peas in the F2 that is expected to be true-breeding (PP) is 1 out of 3.

<span>DNA
stands for deoxyribonucleic acid. The deoxy- in the DNA is a short term for
deoxyribose. The nucleic acid molecule has three parts; sugar, phosphate and a
base. The phosphate in the DNA acts as a backbone of the molecule. It is also
responsible for the DNA’s ‘double-helix’ structure. The base has four codes namely
adenine, thymine, cytosine and guanine. Adenine and thymine are base pairs
whereas cytosine and guanine are base pairs. </span><span>DNA
is a nucleic acid that contains the genetic instructions used in the
development and functioning of all known living organisms whereas the RNA is a
single-stranded chain of alternating phosphate and ribose units with the bases
adenine, guanine, cytosine, and uracil bonded to the ribose. </span>
