Answer:
Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy. Many enzymes change shape when substrates bind.
Explanation:
Answer:
mRNA
Explanation:
mRNA, the messenger RNA is the type of RNA that serves as a template for synthesis of proteins. mRNA is formed by the process of transcription that occurs inside the nucleus. The mature mRNA leaves the nucleus and enter cytoplasm to join ribosome.
The sequence of the nucleotide of mRNA is read in the form of genetic code and each triplet codon signifies specific amino acid to be added to the newly synthesized protein. For the purpose, the tRNAs deliver the specific amino acids to the mRNA-ribosome complex while rRNA are the structural components of ribosomes.
Answer:
It's large compared to other countries, but only because of consumerism
Explanation:
The United States is the 5th largest ecological footprint in the world, with about half the population contributing to that factor, however this is only because the United States runs specifically on capitalism and consumerism, so every citizen contributes one way or another. America uses high energy and fossil fuel consumption with high functioning biological resources in carbon cycling. So although comparing California to France (because California has a larger footprint.), it's not a fair comparision due to technology
Answer:
Option B, Genetic engineering
Explanation:
Biodiversity determines the different types of species living in a given area. Hence it is incorrect
Bioremediation is basically a waste management system in which organisms are used to break down hazardous substances into less toxic substances. Hence, it is also incorrect
Hemodialysis is used to remove or filter out wastes and water from blood. Hence, it is also incorrect
Genetic engineering is used to produce organism with desired trait by altering their DNA and hence the associated Phenotype. Thus, it is the correct answer
Hence, option B is correct
