Calcium channel blockers inhibit the movement of calcium ions from the interstitial fluid into cardiac and smooth muscle cells. This would cause a decrease in heart rate, stroke volume, and cardiac output. These in turn would lower blood pressure. In addition, the calcium channel blockers would also inhibit contraction of the smooth muscle in the wall of blood vessels, causing them to get wider and thus also lower blood pressure. Because both heart and smooth muscle cells are inhibited by verapamil, its effects on blood pressure are particularly potent.
Answer:
Descriptive research is a type of research that studies the participants that take part in the research or a certain situation. Descriptive research does not limit to either of quantitative or qualitative research methodologies, but instead, it uses elements of both, often within the same study. Therefore, a descriptive researcher often uses three major ways to collect and analyse the data. They are observations, case studies and surveys.
now i dont know much about comparisons but im assuming your comparing your own experiment to someone elses to see if you get the same result.
Answer:
The reason it’s so hard to predict the weather very far in advance is because weather is incredibly complex and dynamic. Factors like today’s temperature, humidity, prevailing winds, and local geography all have an influence on tomorrow’s weather. What happens tomorrow determines what will happen the next day, and so on. Even the tiniest unknown factor in today’s weather, say the humidity over a patch of forest, increases the uncertainty of making tomorrow’s forecast. The situation makes the forecasts for next week even less certain, and forecasting even further into the future becomes increasingly more challenging.
Climate is very different. While climate is also an exceedingly complex system, we aren’t looking at local, day-to-day details, but rather focusing on the average conditions for a region over time. And those change much more slowly. Nobody can tell you what the temperature will be on August 10, 2020, in New York City, but it’s very likely to be a lot warmer than on February 10, 2020, because New York City’s climate is hot in summer and cold in winter. The city also happens to have a fair amount of both rain and snow. The climate in San Diego, California, is warm, but not hot most of the year, with relatively little rain and essentially no snow. Buffalo, New York, is very cold in winter and gets a huge amount of snow. And so on. You instinctively know the climate where you live because it doesn’t change a lot from year to year.
Ans. Phenylalanine.
Genetic codes or codons are triplet codes, made up of three nucleotides. Each genetic code codes for a particular amino acid during translation. There are total 64 codons, out of which 61 codes for amino acids, while 3 act as stop codons.
According to Universal Genetic Code chart, first genetic code is UUU that codes for phenylalanine amino acid.
Thus, the correct answer is option). 'phenylalanine.'
