The property of polarity of the water and cohesion could be the actual responsible for the beading up of water on the surface of leaves.

What is cohesion?

Cohesion, also known as cohesive attraction or cohesive force, is the action or quality of like molecules sticking together and being attracted to one another (from the Latin cohaesi, "cohesion, unity"). The uneven distribution of surrounding electrons that results when molecules are close to one another creates electrical attraction, which can keep a small structure like a water drop in place. This attribute of a substance is caused by the shape and structure of its molecules. Surface tension is made possible by cohesion, resulting in a "solid-like" state that allows for the placement of light or low-density materials.

It turns out that the tendency of water molecules to attract one another, or the tendency of cohesion, is what causes surface tension. The "lowest energy state," or the state in which the atoms in the molecule are utilizing the least amount of energy, is when a water drop takes on its natural form. This condition of water occurs when a water molecule forms a sphere or ball and is encircled by other water molecules on all sides. On Earth, gravity flattens this perfect sphere into the form of a drop that we can perceive.

Many scientists believe horizontal gene transfer (HGT) is a significant source of genetic variation. Why
lawyer [7]

In prokaryotes, horizontal gene transfer (HGT), the transfer of genetic material from one organism to another organism within the same generation, is an important way to promote genetic diversity. HGT allows even distantly related species to share genes, influencing their phenotypes.

Transformation: Mode of genetic transfer in which “bare DNA” is taken up from the environment is taken up by cells

Transduction: Mode of genetic transfer in which genes are transferred by a bacteriophage to a bacterial cell

Conjugation: Mode of genetic transfer in which two cells must come in contact and genetic material is transferred to a recipient cell from a donor cell through its pili

How many chromosome would be found in dog gametes?
mezya [45]
In dog gametes, there are half the chromosomes contained in normal diploid cells. In the normal diploid cell of the dog there are 78 chromosomes, thus, in dog gametes, there are 39 chromosomes.
Similarly, in deer mouse brain cells there are 48 chromosomes since brain cells are diploid cells.
In gametes there are half of that number, so in deer mouse gametes there are 24 chromosomes.

The sword-billed hummingbird has the longest bill of all birds compared to its body size. Its beak is perfect for drinking necta
iris [78.8K]

This is an example of co-evolution.  

<u>Explanation:</u>

In co-evolution one species or a number of species evolve according to the changes in another species. Here the evolution of the beak of humming bird according to the shape of Ossifloramixta flower is an example of co-evolution. Co-evolution is common in the nature.  

Bees, insects and butterflies commonly co evolve with the flower plants and  vice versa. Co-evolution is of two types. The first type is specific co – evolution where only two parties are involved in co-evolution. In the second type of co-evolution namely diffused co-evolution many species evolve in response to specific traits in a species.
