Strict respiror require strict oxygen condition do it is strict aerobes while strict ananerobes doesnot require oxygen in strict sense.
So both are different.
Thioglycolate medium is used for checking oxygen requiring condition for bacteria as this medium consume oxygen slowely so those bacteria which is strict aerobes grow at top to gain oxygen from surface of this medium while strict anartobes grown botton down away from surface to avoid any contact with oxygen.
Hope it's clear..thanks
are strict respirers and strict anaerobes the same thing? is either yes no, would their oxygen...
Are the textbook solutions the same thing as a test bank or is that different? I am looking for the test bank for ISBN 13: 9781451146004
would either of your attributes be allowed to contain NULLS? Yes or No? Explain why or why not in database why you can't
In an experiment. it is possible to calculate the moles of oxygen from either the volume formed at STP or from the weight of oxygen generated. Which gives the more accurate value? Why? Explain thee effect that failure to subtract the water vapor pressure from the total pressure would have on your determination of molar volume? (Would your molar volume be too high, the same, or too low and why?)
10. The output gap in this video would be the same thing as Optional Answers: 1. inflationary or recessionary gap in the book 2. When firms are not using the correct resources to produce goods and services 3. a decrease in cyclical unemployment 4. a change in price level 11.

Post an example of a scenario that would warrant either a one-sample or a two-sample test. This can be a hypothetical example. Please state H0 and H1 and explain why your hypothetical example qualifies as either a one- or two-sample test. (Please recognize that one- and two-sample tests are not the same as one- or two-tail tests.) Also, clearly state the reason(s) this hypothesis test would be conducted. You do not actually have to complete the hypothesis test steps.

Please answer 3&4 W GIVOTU Muu ovat LED uro. QUESTION 3 Suppose you place yeast cells in two different environmental conditions to observe their growth. Flask A contains nutrient broth that has minimal amounts of glucose and is incubated at 37°C with aeration (like a bubbler in a fishtank). Flask B has the same media, is incubated at 37°C and is kept in an anaerobic environment. The yeast are facultative anaerobes. Which culture had the greater number of cells? Flask...

(a) For the same data and null hypothesis, is the P-value of a one-tailed test (right or left) larger or smaller than that of a two-tailed test? pick one The P-value for a one-tailed test is smaller because the two-tailed test includes the area in both tails. The P-value for a one-tailed test is larger because the two-tailed test includes the area in only one tail. The P-value for a one-tailed test is larger because the two-tailed test includes the...
9.(10 points) If you collect 0.680 L of a sample of oxygen over water at a temperature of 27.0 °C and 774 torr, what volume would the dry gas occupy at the same conditions of temperature and pressure?
