How long would you expect the cell cycle to be at 5 degrees Celsius?
At 5 degrees Celsius, the cell cycle will likely be longer than at higher temperatures due to decreased biochemical reaction rates. The exact length can vary depending on the cell type and environmental conditions, but generally, it would be much slower compared to physiological temperatures around 37 degrees Celsius.
If bacteria used in an experiment - were kept at a temperature of 100 degree Celsius - would you expect the population sizes to increase even faster than at 15 degree Celsius?
No, bacteria generally thrive at moderate temperatures that fall within their optimal growth range. A temperature of 100 degrees Celsius would likely be too high and could lead to cell damage or death, inhibiting bacterial growth. Population sizes would not increase faster at this extreme temperature compared to 15 degrees Celsius.
If amylase is added to a sample of potato and you test it with Benedict's reagent 10 minutes later what do you expect of the results to be?
If amylase is added to a sample of potato, which contains starch, it will break down the starch into simpler sugars like maltose. When tested with Benedict's reagent after 10 minutes, you would expect a color change to occur, indicating the presence of reducing sugars. A positive result, typically seen as a color change from blue to green, yellow, orange, or red, suggests that amylase has effectively hydrolyzed the starch into sugars.
If the optimum temperature for lactase is 37 degrees C at what temperature would you expect the enzyme to denature?
Enzymes, including lactase, typically begin to denature at temperatures significantly above their optimum. For lactase, which has an optimum temperature of 37 degrees Celsius, denaturation may start occurring around 45-50 degrees Celsius. However, the exact temperature can vary depending on the specific enzyme and environmental conditions. Prolonged exposure to high temperatures can lead to irreversible denaturation, causing a loss of enzymatic activity.
What form will precipitation take at 2 degrees Celsius?
This question is actually more complicated than it sounds. Water freezes at 0 degrees celcius. From 1° to 99° you'll have liquid water. So if the air temperature is 2° C you might expect liquid precipitation. But you might get a surprise when step out and see snow falling. Here's why. Precipitation falls through several thousand feet of air before you actually see it. If the air temp. near you is 2° C but the air from say above 1000 feet up to 9000 is -5° C you might get ice.
If starch was incubated with amylase at 0 degrees celsius would you expect to see any starch digestion?
no
Would you expect to get the same value for the density of a liquid at 20 degrees Celsius and at 40 degrees Celsius?
No, the density of a liquid usually decreases as temperature increases because rising temperature causes molecules to spread out. Therefore, you would generally expect the density of a liquid to be lower at 40 degrees Celsius compared to 20 degrees Celsius.
What pressure would you expect in a rigid container of 0 degrees Celsius gas if you cooled it by 273 degrees Celsius?
The pressure would decrease to zero because a gas at 0 degrees Celsius is frozen, and frozen gas does not exert any pressure due to lack of molecular motion.
Which state of matter would you expect to find water at 20 Celsius on Earth?
In a liquid, as at sea level water's boiling point is 100 degrees and it's freezing point is 0.
What type of precipitation occurs at 25 degrees celsius?
At 25 degrees Celsius, the most likely type of precipitation would be rain. Snow and sleet typically occur at temperatures below freezing (0 degrees Celsius), while hail usually forms within severe thunderstorms.
How many chirps would you expect when the temperature is 10 degrees Celsius?
The correlation between cricket chirps and the temperature is very approximate.
In Perth what is the average temperature in summer?
At the moment (February) it is summer time in Perth Western Australia. 37 degrees celsius today. In February we can expect temperatures in the 40 degree mark.
If the temperature at sea level were 23 degrees Celsius what would the air temperature be at the height of 2 kilometers under average conditions?
The average decrease in temperature with altitude is around 6.5 degrees Celsius per kilometer, known as the lapse rate. At 2 kilometers above sea level, we would expect the temperature to be approximately 10 degrees Celsius lower than at sea level. Therefore, at a height of 2 kilometers, the air temperature would be around 13 degrees Celsius under average conditions.
What type of precipitation is 16 degrees Celsius and 61 degrees Fahrenheit?
Well, it would have to be rain since the temperature is above freezing. BTW - maybe you knew this already - 16oC is equivalent to 61oF
How long would you expect the cell cycle to be at 5 degrees Celsius?
At 5 degrees Celsius, the cell cycle will likely be longer than at higher temperatures due to decreased biochemical reaction rates. The exact length can vary depending on the cell type and environmental conditions, but generally, it would be much slower compared to physiological temperatures around 37 degrees Celsius.
Why do Fahrenheit sides has more numbers than the Celsius sides?
1 degree Celsius is equal to 9/5 degrees Fahrenheit. Or it is easier to think that one degree Celsius is approximately two degrees Fahrenheit. So, if one has a thermometer that reads both Fahrenheit and Celsius, one would expect about twice the range of numbers on the Fahrenheit side, as well as potentially having more numbers marked on the scale.
What value do you expect for the absolute zero temperature for different gases?
The value of absolute zero temperature is the same for all gases, which is -273.15 degrees Celsius or 0 Kelvin.
