b. economic consequences
c. development hindrances
d. all of the above
Answer: d. all of the above
Fossil fuels such as coal, oil and gas are beneficial sources of energy used by the human society. Fossil fuels are non- renewable resources, which are produced after millions of years of geological and biological activity taking place inside the earth crust. Human society is mainly dependent upon the fossil fuels to maintain it's energy needs.
There are some negative consequences associated with fossil fuels:
Environmental consequences: Fossil fuels are used for generation of energy in the power plants and by the automobiles. These sources releases partially and completely combusted products which includes the poisonous gases causing air and water pollution.
Economic consequences: Fossil fuel use is related with economic crisis because fossil fuels are non- renewable resources, which cannot be replenished once used. They are expensive and many commercial energy generation processes are dependent on them such as electricity, transportation and others.
Development hindrances: Large dependence on fossil fuels creating an hindrance on development process. As, there are very few findings which are resulted which could replace the fossil fuels, these finding can be beneficial for the environmental and economic point of view.

2. A woman buys red-flowering and blue-flowering plants of the same species and plants them in her garden. The plant undergoes both self-fertilization and cross-fertilization. The woman collects seeds and plants them the following spring. What can the woman expect to observe in the flowers of the new generation of plants if the gene for flower color is codominant? (1 point)
plants with red flowers and plants with blue flowers
plants with both red and blue flowers
plants with red flowers, plants with blue flowers, and plants with purple flowers
plants with purple flowers
3. What is formed at the end of meiosis?
two genetically identical cells
four genetically different cells
four genetically identical cells
two genetically different cells
4. Which of the following is true concerning DNA replication?
The original DNA molecule remains intact, although it acts as a template for the formation of a copy that contains two new antiparallel strands.
The leading strand is copied in the 5’ to 3’ direction and the lagging strand is copied in the 3’ to 5’ direction.
Both strands are copied to form Okazaki fragments, which are later annealed by DNA ligase.
The replication process proceeds on both strands in the same direction, which requires that RNA primers bind to the lagging strand.
5. Which of the following will be directly affected in a bacterial cell that has a mutation in its gene for RNA polymerase?
Which of the following will be directly affected in a bacterial cell that has a mutation in its gene for RNA polymerase?
transcription
translation
gene regulation
Answer:
B, Clastic rock
Explanation:
Clastic rocks are those formed by fragments of another sedimentaries rock (clasts) and minerals around those clasts, there are so many types of clastic rocks according to the place those were formed, the mineral and clasts composition and some times the shape of the clastic rocks becomes helpful to the classification.
Answer:
B. Clastic
