They can use those recently discovered genes and insert them in another species (fruits and vegetables) using genetic ingeniery technics so they can speed up the cell division on them, and accordingly increase the production.

The correct answer is B. Ordovician period
Explanation:
Plants are mainly multicellular organism that depends mainly on photosynthesis to obtain energy, this includes a wide variety of species such as grass, flowering plants, trees, shrubs, etc. Additionally, plants are considered as one f the two major divisions or kingdoms along with animals. In terms of history, it has been determined first land plants appear during the mid-Ordovician period around 470 million ago, although organisms that were the origin of land plants developed in water in previous periods, also by the Devonian period a wide variety of plants have emerged with features that are still part of plants nowadays.

Answer:
A student visits the beach during a very hot day. She steps on the sand and jumps because it is so hot as a result of "conduction."
Explanation:
The process of the conduction happens because of the flow of kinetic energy from one molecule to the other by direct contact.  When she first steps the beach on the hot sand, after that the energy moves from the hot sand to the cooler body by conduction. While walking on the sand for few time, the feet will feel hot. The movement of the heat takes place from the hot sand to the bottom of the feet by conduction. When the objects come in contact with each other the heat transfers as a result of conduction.
