Answer:

D) adhesion

Explanation:

Adhesion is a water property that allows water molecules to adhere to each other. This can occur thanks to its polarity. Water tends to attract and be attracted to other polar molecules. This attraction between water molecules and other polar molecules is called adhesion. When the slope occurs the water surface becomes curved, as shown in the figure.

Water molecules do not bind with nonpolar molecules, ie there is no adhesion. Therefore it is not evenly distributed on a waxed surface, and forms separate droplets on them, as the wax is nonpolar.

mariarad [96]

Answer:

in the obtained options, there is no dominant gene for the crossed pairs, therefore, no answer would be correct, however, when assigning a dominant character to the P gene, the correct answer would be:

E. Rr pp *rrPp

Explanation:

According to the information obtained we deduce:

Comb shape is produced by R and P

Comb of walnuts with an R or a P

Pink comb: 1 dominant P and R at the first locus and 2 recessive at the next locus

Pea comb: 2 recessive at the start and one dominant in the next position

1 single comb: 2 recessive at both loci

Rr pp × rr Pp will produce from the interbreeding: 2 walnuts, 1 single and 1 pea offspring.

We deduce that for the pink comb the genotype is: Rrpp

and for the pea comb it is rrPp

Rr pp × rr Pp generates crosslinks containing RrPp, rrPp, rrpp as children in a 2: 1: 1 ratio.

What geological evidence could there be for the presence of an early ocean?
e-lub [12.9K]

Answer:

Volcanic degassing of volatiles, including water vapour, occurred during the early stages of crustal formation and gave rise to the atmosphere. When the surface of Earth had cooled to below 100 °C (212 °F), the hot water vapour in the atmosphere would have condensed to form the early oceans.
