Define Heat, Thermal Energy, Conduction, Convection and Radiation
Leya [2.2K]
Heat:  it is a form of energy associated with the movement of atoms and molecules in any material.<span>The higher the temperature of a material, the faster the atoms are moving, and hence the greater the amount of energy present as </span>heat<span>. 

Thermal Energy: t</span>he internalenergy<span> of an object due to the kinetic </span>energy<span> of its atoms and/or molecules. The atoms and/or molecules of a hotter object have greater kinetic</span>energy<span> than those of a colder one, in the form of vibrational, rotational, or, in the case of a gas, translational motion.

Conduction: </span><span>the process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material.

Convection: </span>the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.

Radiation: the emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles that cause ionization.

Defend or refute the conclusion that technology has improved animal agriculture.
Lana71 [14]

Answer:

Since genetically engineered (GE) crops were introduced in 1996, their use in the United States has grown rapidly, accounting for 80-90 percent of soybean, corn, and cotton acreage in 2009. To date, crops with traits that provide resistance to some herbicides and to specific insect pests have benefited adopting farmers by reducing crop losses to insect damage, by increasing flexibility in time management, and by facilitating the use of more environmentally friendly pesticides and tillage practices. However, excessive reliance on a single technology combined with a lack of diverse farming practices could undermine the economic and environmental gains from these GE crops. Other challenges could hinder the application of the technology to a broader spectrum of crops and uses.
