Answer from: jskdkfjf

The diagram for evolution of plants in the 4 stages is attached below.

Explanation:

The plants evolution has 4 main periods:

A. 1st Period of Plant Evolution

About 420 million years ago, plants evolved from algae. Formation of cuticle was the first terrestrial adaption.

B. 2nd Period of Plant Evolution

Abut 400 million years ago, the diversification of vascular plants came into being. The early vascular plants lacked seeds.

C. 3rd Period of Plant Evolution

This was around 360 million years ago, that the seed evolved. The plants had seeds, but they did not have any covering, so they were called naked seeds. These plants were gymnosperms.

D. 4th Period of Plant Evolution

This was the evolution of flowering plants, happened around 130 million years ago (during early Cretaceous period). The flowering plants were called angiosperms.

4.) metal

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."

The human genome project is devoted to mapping the general dna sequence of our species. this could lead to the development of new medicines, as well as the possibility of using gene therapy to treat certain diseases. however, there are some ethical issues surrounding the mapping of individual genomes. one concern is a) that your genes may change over time, making the project useless. b) that insurance companies could discriminate based on genetic make-up. c) that since this has never been done before, we should probably not do it now. d) that sequencing our individual genomes is so expensive, it is a counter-productive strategy.
