The increasing demands for fossil fuels has led governments and businesses to
consider several possibilities to solve the energy crisis. Which solution will reduce the
impact of this crisis on the environment and future generations?
(1) increase the number of drilling sites for crude oil in North America
(2) build more power plants away from population centers
(3) limit the number of people in each vehicle
(4) develop alternative fuel sources that can be produced from renewable
resources
The rise of fossil fuels demands various nations has created problems for the government to meet the increasing supplies as fossil fuels are fast depleting and heavily pollute the environment at large.

A magazine published an article stating that drinking water obtained from waste water is harmful for health. Why is this information most likely to be incorrect? The article does not provide a scientific basis for the information magazines do not generally publish reliable scientific information drinking water has been obtained from recycled waste water since many years scientific tests show that drinking water obtained from waste water is pure and safe
Answer:
The correct answer is - the article does not provide a scientific basis for the information
Explanation:
Generally, Magazines publish articles with reliable information and sources that are universally accepted or have a scientific basis behind the information. It is already known that wastewater is recycled and purified before making it available for drinking.
In this article, there is no scientific basis behind the information as no scientific data mentioned or ignore test and practice in use from the years which is scientifically tested.

what is the difference between redshift and blueshift?
Answer:
Redshift and blueshift describe how light shifts toward shorter or longer wavelengths as objects in space (such as stars or galaxies) move closer or farther away from us. The concept is key to charting the universe's expansion. Visible light is a spectrum of colors, which is clear to anyone who has looked at a rainbow.

What is cell?
Cell is defined as the base of life as it is the structural as well as functional unit of life. Cell is made up of pre existing cells and the cell contain various cell organelles such as mitochondria, endoplasmic reticulum, ribosomes, golgi appratus, nucleus, and cytoplasm.
Basically,cell is of two type one in prokaryotic and another one is eukaryotic. The prokaryotic cell is known as pre mature cells as they do not contain cell organelles and eukaryotic cell are known as advanced and developed cells as they contain several cell organelles.
The unicellular animals are made up of single cell and all the functions carried out in a single cell like amoeba and multicellular organisms are made up of multiple cells and there is specific cell for specific functions.
Therefore,The statement which is not true is it needs a vesicle to move the matter. Thus, option C is correct.

PLZ HELP IM TAKING MY EXAM!! which of the following best explains the impact of mrna being double stranded before translation
Answer:
Impact of double-stranded mRNA before translation would inhibit the binding of tRNA to mRNA ti synthesize protein.
Explanation:
The mRNA is a molecule that, with the exception of viruses with double-stranded RNA, has only one chain. It is in charge of conducting to the ribosomes the sequence of nucleotides that makes possible the translation and the synthesis of proteins.
Once the ribosome translates the information of each codon of the mRNA, a transfer RNA (tRNA) molecule, with a complementary anticodon, provides the amino acid corresponding to the translated codon.
If the mRNA were double-stranded, the translation process would be altered, since binding of the tRNA with the amino acid it carries and mRNA codon would not be possible, as well as the protein synthesis.

summarize in your own words how plants take energy from the sun and convert it into chemical energy (sugar)
Answer:
Steps of photosynthesis:
Step 1: Energy is captured from sunlight.
Step 2: Light energy is converted to chemical energy,
which is temporarily stored in ATP and the energy
carrier molecule NADPH.
Step 3: The chemical energy stored in ATP and NADPH
powers the formation of organic compounds, using carbon
dioxide (CO2 ).

If you are neither relaxing or contracting a specific muscle, what is happening to the amount of ATP that is available in that muscle cell?
A. It is staying the same or increasing.
B. It is decreasing rapidly.
Answer:
A. It is staying the same or increasing.
Explanation:
The body tissues and cells require energy in the form of ATP to work, grow and move. It is produced from cellular processes like ETC, cellular respiration and other metabolic processes.
The amount of ATP in the cell:
Option A. It stays the same or increases.
The function of ATP can be explained as:
Muscle contraction and relaxation requires a certain amount of energy in the form of ATP. The insufficient amount will not be able to support the relaxation or the contraction of the muscle tissues.In the condition where there is no contraction or relaxation the amount of energy will be the same or increased as it is not used in the process and remains constant.Therefore, it remains the same or increases.
