Answer:

Crossing over is the phenomena of the process of exchange of genetic material between the non sister chromatids of the homologous chromosomes.

The crossing over results in production of the new recombination. This produces the genetic variation in the individual that may be harmful or beneficial. The process of crossing over provides the way by which the genetic variation can be introduced in the organism.

How does heat transfer from the tea to the spoon?
Licemer1 [7]
This occurs through conduction when two things get in contact with each other.

here's a definition from kid's britannica: "<span>Conduction transfers heat within a body or between two bodies that are touching. It is a point-by-point process of heat transfer.

What is considered the ultimate wonder of cells
Lapatulllka [165]
According to G.D Budhiraja in his book "The Natural Way of Healthy Aging," the ultimate wonder of cells is the egg cell. 

The egg cells is considered to be the ultimate wonder of cells because of its potential to form another human being. Once fertilized, the egg cell multiplies and grows, and "seems to know" just the right timing for certain processes to occur within the embryo or fetus. It seems to know when certain hormones should be produced, when it should implant in the uterus, and when the hands, legs, feet, hair, and other parts of the embryo and fetus should grow.

slamgirl [31]
Talking of taxonomic kingdoms, the organism belongs to kingdom Animalia. Among other kingdoms, Archaea, Bacteria, and Protozoa are unsuitable since they include unicellular organisms. This organism can move freely from place to place, thus, it couldn't be neither Plantae nor Fungi, leaving Animalia as the only matching kingdom.
