Answer:
A: Unlike DNA, XNA replicates conservatively
Explanation:
<em>The replication of the DNA is </em><em>semi conservative.</em><em> This means that newly replicated double helix DNAs usually consist of one parental strands and one newly synthesized strands. The parental DNA unwinds and each strand serves as template for the synthesis of complementary strands.</em>
In the case of XNA, the two strands of parental XNA were found intact, meaning that the newly produced XNA consist of two newly synthesized strands. This thus means that the replication process is conservative.
Hence, unlike DNA replication that is semi conservative, XNA replication is conservative.
Answer:
I believe the correct answer would be D- Plant cell do not have cytoplasm
Explanation:
Plant and animal cells both have a cytoplasm so D is the incorrect statement.
Answer: They lead to increased levels of carbon dioxide and other greenhouse gases in the atmosphere which causes the greenhouse effect.
Renewable resource: Sunlight, water, wind,
Norenewable: coal, natural gas, oil
Since fossil fuels are located all over the world, it makes it much easier to create electricity from them than things that are hard to come by.

It is the same as creating more pests or setting up dominant species which upset the ecological food pyramid leading to decimation of trophic levels or predators and energy cycling. Fishes feed on microscopic algae and animals the primary base of the food chain in water, if they are not checked they will choke the rivers and oceans causing toxic waters. Fish feed to contain them, in the process they grow and increase in numbers but their population is checked by bigger fishes and so on till it reaches a top predator which is usually a large animal.
