Explanation:
DNA and RNA base pairing is slightly different since DNA uses the bases adenine, thymine, cytosine, and guanine; RNA uses adenine, uracil, cytosine, and guanine. Uracil differs from thymine in that it lacks a methyl group on its ring.
Answer:
Qualitative research seeks to understand why people react and how they feel about a specific situation. Quantitative research measures numerical results to help predict possible outcomes. In other words, qualitative research is concerned with "why," whereas quantitative research is concerned with "what."
Explanation:
Oil-immersion objectives are limited to use with coverslip-prepared samples, since they don't have enough working distance to focus through the 1 mm or thicker plastic wall of a typical cell culture vessel.
Answer:
Redox reaction
Explanation:
Redox reaction involves both reduction and oxidation of substances. The lithium atom is reduced as it loses the electron while chlorine is oxidised as it gains an electron. An equilibrium state is obtained and lithium chloride is formed.
Answer:
The correct answer is "a large-scale natural system such the Great Lakes".
Explanation:
Mathematical models are used in scientific investigations to study complex systems. This applies to the study of ecosystem dynamics of large-scale natural systems such as the Great Lakes. The Great Lakes comprise five lakes that in conjunction are 244,106 km2 long, with a complex ecosystem that includes invasive species, climate change, pollution, among other factors. It will be very complicated to study the ecosystem of such a large habitat without using mathematical models.
