Some reasons that people give for smoking:
> they believe it reduces stress and anxiety ( scientific studies show this isn't factual and the chemicals within smoking products is only made appealing and or distracting to make the user believe so. It actually heightens stress levels and lowers health levels)
> this sounds cliche but, teens often think its cool or get peer pressured into it. They find themselves wanting to try harmful substances and get addicted. ( in one study there were d r u g s found in smoking products aimed to get the attention of children and young adults. It's all a marketing ploy for business men and women to collect money as you slowly grow more and more breathless)
> lastly, "it's not that bad for you" often, markets and cig stores tell potential buyers its not as bad as other things. Some say its not harmful at all.( Lung disease,gum disease,heart failure,etc. all disprove this. Each year about 480,000 people die from the affects of smoking)

Which of the following directly causes deforestation?
A. Wind
B. Biomass
C. Nuclear fission
D. solar
Answer:
The answer is C. Wind levels usually remain static in a specific location, so any existing life is not affected much. Biomass contributes to growth as it enriches the soil. Solar (assuming it's referring to the widespread increase in the use of solar energy) could actually be indirectly beneficial to forests. Nuclear fission, however, can cause harm to plants. Some known effects on plant life include stunted growth, reduced germination, and genetic mutations in addition to the direct burning that could be inflicted on plants in some cases.

RNA polymerase is said to have high _____, meaning that it can catalyze thousands to millions of reactions without releasing the DNA template
Answer:
processivity
explanation
RNA polymerase is said to have high processivity, meaning that it can catalyze thousands to millions of reactions without releasing the DNA template
RNA polymerase is said to have high A) processivity, meaning that it can catalyze thousands to millions of reactions without releasing the DNA template.
Processivity refers to the ability of an enzyme to remain attached to its substrate and catalyze multiple consecutive reactions without dissociating. In the case of RNA polymerase, it is responsible for synthesizing RNA molecules by using a DNA template.
RNA polymerase exhibits high processivity, meaning that once it binds to the DNA template, it can catalyze the formation of RNA molecules for an extended period without releasing the DNA template. This allows for the efficient synthesis of long RNA strands.
During transcription, RNA polymerase moves along the DNA template, unwinding the DNA double helix and adding complementary RNA nucleotides to the growing RNA chain. It remains attached to the DNA template throughout this process, continuously elongating the RNA molecule.
The high processivity of RNA polymerase is essential for the accurate and efficient transcription of genes. It ensures that the RNA molecule is synthesized without interruptions or premature termination. This processivity allows RNA polymerase to transcribe entire genes or long stretches of DNA without dissociation, facilitating the synthesis of functional RNA molecules.
Overall, the high processivity of RNA polymerase contributes to the fidelity and efficiency of transcription, allowing for the synthesis of RNA molecules that faithfully represent the information encoded in the DNA template.

what's kreb cycle? explain in brief
Answer:
Kreb cycle is the sequence of reactions by which most living cells generate energy during the process of aerobic respiration. It takes place in the mitochondria, using up oxygen and producing carbon dioxide and water as waste products, and ADP is converted to energy-rich ATP.
Explanation:
Definition:
A cycle of reactions catalyzed by enzymes in which the pyruvate derived from nutrients and converted to Acetyl Coenzyme A is completely oxidized and broken down into carbon dioxide and water to produce high-energy phosphate compounds, which are the source of cellular energy.
In eukaryotes, the Krebs cycle reactions take place in the mitochondrial matrix, a dense solution that surrounds the mitochondria crests: in addition to water, the matrix contains all the enzymes necessary for the biochemical reactions of the cycle, coenzymes, and phosphates.
Equation:
The overall reaction for the citric acid cycle is as follows: acetyl-CoA + 3 NAD+ + FAD + GDP + P + 2H2O = CoA-SH + 3NADH + FADH2 + 3H+ + GTP + 2CO2.

What is the function of DNA? It takes the message of the amino acid order for proteins to the cytoplasm, where the protein will be built. It serves as an enzyme to speed up many kinds of biochemical reactions in the cell. It builds proteins from amino acids using the instructions stored in RNA. It stores in the nucleus the information a cell needs to make its proteins with the right orders of amino acids.
Answer: The answer is B. (It stores in the nucleus the information a cell needs to make its proteins with the right orders of amino acids.)
Explanation: I took the test and this was the answer! :)
The function of DNA (deoxyribonucleic acid) is to store and transmit genetic information from one generation to the next, and it stores in the nucleus the information a cell needs to make its proteins with the right orders of amino acids. That is the last option.
What is DNA?DNA is a molecule composed of long chains of nucleotides. A nucleotide is made up of three components: a sugar molecule, a phosphate group, and a nitrogenous base. The process of gene expression begins with the transcription of DNA into RNA (ribonucleic acid). RNA is a molecule similar in structure to DNA but with a few key differences, such as the presence of the nitrogenous base uracil (U) instead of thymine. DNA also plays a role in the regulation of gene expression. Certain regions of DNA, called promoters and enhancers, help to control when and where a gene is expressed.
Hence, it stores in the nucleus the information a cell needs to make its proteins with the right orders of amino acids. That is the last option.
