Answer:
Adhesion and surface tension
Explanation:
Capillary action is the tendency of a liquid to rise or fall in a narrow tube. Two main terms are required to explain capillary action; adhesion and cohesion.
Cohesion is the force of attraction between molecules of the same kind while adhesion is the force of attraction between molecules of different kinds.
Forces of adhesion causes water to move up in a capillary tube. The water is held as it rises by surface tension forces acting on the circumference of the meniscus. The water keeps rising in the tube until the weight of the water drawn up in the tube balances the surface tension acting at the top column of the water.
Answer:
Water spills out if the sponges are wet, and nothing happens if they are dry.

Answer:
The correct option is <em>B. 25 %</em>
Explanation:
A heterozygous type can be described as the type in which both the alleles of a gene are different. If both the alleles of a gene are similar in an organism, then the person is said to be homozygous for the trait.
In the above question, two heterozygous parents are to be cross- bred to check the probability of them producing homozygous alleles (AA).
A punnet square made will show the following results:
A O
A AA AO
B BA BO
Hence, there will be 25% chance that the offspring produced could be homozygous AA.

Explanation:
The cellulose make stems, leaves and branches. So it play an important role in building of tissues. So it give the shape to plant. The molecules of cellulose have hydroxyl group that form hydrogen bonding with other cellulose and prrovide support to plant.
