In summer squash, white fruit color (A) is dominant over yellow fruit color (a). If a squash plant
homozygous for white is crossed with a plant homozygous for yellow, what will the phenotypic and
genotypic ratios be for:
In a biochemical assay, a chemist needs to add 2.93 g of glucose to a reaction mixture. Calculate the volume in mL of a 1.35M glucose solution she should use for the addition.
the result of a particular examination are given in the table below
passed with distinction 10%
passed without distinction 60%
failed 30%
it is known that a candidate fails in the examination if he obtains less than 40 marks while he must obtain at least 75%marks in order to pass with distinction . determine the mean and standard deviation of distribution of marks .assuming these is to be nominal
If another galaxy is seen at a redshift of 0.5, what redshift would it see us at?
An investigator thinks that people under the age of forty have vocabularies that are different than those of
people over sixty years of age. The investigator administers a vocabulary test to a group of 31 younger
subjects and to a group of 31 older subjects. Higher scores reflect better performance. The mean score for
younger subjects was 14.0 and the standard deviation of younger subject's scores was 5.0. The mean score
for older subjects was 20.0 and the standard deviation of older subject's scores was 6.0. Does this
experiment provide evidence for the investigator's theory?
The series combination of five cells, each electromotive force of 1.5 V and internal resistance of 0.5Ω, is connected to an external resistance of 5.0 Ω. Find the (a) total internal resistance, (b) electromotive force of the battery, (c) total resistance of the circuit, (d) current through the external circuit, (e) terminal voltage of the battery, and (f) terminal voltage of a cell.
The technologist in the STAT lab evaluates another problem sample. This specimen had a creamy tomato soup appearance in the heparinized whole blood specimen. The results of laboratory testing are listed below. Test Sodium Potassium Chloride Bicarbonate Anion gap Patient 135 mmol/L 3.6 mmol/L 99 mmol/L 24 mmol/L Reference-Ranges 136-145 3.5-5.1 98-107 22-28 10-20 16 1. If you are the Med. Tech. What result/s are erroneous Why? 2. What are the expected results of ALL the test? Enumerate and explain why 3. What will you do to correct the error? What method will you use if you decide to repeat the test?
Suppose you have GH¢ 5.00. If you use the money to pay electricity bill, you will gain or benefit, in monetary terms, GH¢ 8.00 whiles if you use it to board a taxi you will gain GH¢ 10.00.
(a) What is the opportunity cost for spending the money on transportation (taxi)? (b) What is the opportunity cost for spending the money on electricity bill?
(c) What is the net benefit when
(i) the direct cost is used?
(ii) the opportunity cost is used?
(d) From your results in (cii) which good should you purchase? Explain your answer.
suppose you have $5.00 if you use the money to pay electricity bill you will gain or benefits monetary terms $8.00 whiles if you use it to board a taxi you will gain $10.00.
what is the opportunity cost for spending the money on transportation
A galvanometer with a resistance of 15.0Ω gives a full-scale reading for current of 3.0 A. What shunt resistance is needed to convert this into an ammeter with a 30.0 A full-scale reading?
