Computer models have shown how increases in carbon dioxide in the atmosphere will change sea levels around the globe. Based on this
information, does the Earth's atmosphere represent an open system or a closed system?
A. Earth's atmosphere is a closed system because energy can enter or leave the system but no significant amount of matter can enter or leave the system.
B. Earth's atmosphere is a closed system because no significant amount of energy or matter can enter or leave the system.
C. Earth's atmosphere is an open system because energy can enter or leave the system even though no significant amount of matter can enter or leave the system.
D. Earth's atmosphere is an open system because significant amounts of both energy and matter can enter and leave the system.

A) While the earth itself is a closed system, all systems inside the earth's atmosphere are considered open systems. An open system is a system in which both energy and matter transfer with their surroundings

B) The earth is a closed system because only energy is naturally transferred outside the atmosphere. Matter needs to break physical laws in order to leave the earth's atmosphere, and outside matter, such as meteorites, is prevented from getting

C) Energy radiates into the Earth’s system, mainly from the sun. Energy is then radiated back into space from the Earth, with the flows being regulated by the Earth’s atmosphere and ozone layer. This delicate balanced transfer of energy maintains the surface temperature at a level that is suited to the forms of life that have evolved and currently exist

D) Any system within the Earth system is considered an open system. Because energy flows freely into and out of systems, all systems respond to inputs and, as a result, have outputs

chromosomes carry the genetic information for organisms. also, chromatin is the thread like dna which is located in the nucleus of an organism.

answers are:

lysogenic     viral dna merges with host cell dna

lysogenic     no symptoms

lytic               viral dna takes over

lysogenic     virus does not destroy host cell

lytic               virus destroys host cell

lytic               induces symptoms of viral infection

lysogenic       cell reproduces and spreads provirus
