Answer:
48 hours
Explanation:
Patch testing is a method to test the allergic reactions called contact dermatitis caused by the allergens found in the environment the patient is surrounded by like home allergens or work allergens.
To perform the test, the allergens are placed on the metal discs which are pasted on the back of the person with hypoallergenic tape.
Then the discs are allowed to be pasted on the back of the person for about 2 days or 48 hours after which the skin is examined for the allergy reactions caused by an allergen in the form of inflammatory response or hypersensitivity.
Thus, 48 hours is the correct answer.
Answer:
C. Document the number of honey-making bees per hive.
Explanation:
Among the given options, the only useful criteria towards the experimental design of honey production are to "document the number of honey-making bees per hive". We know that the increased number of animals would increase the workforce and thus increase the production of honey (direct relation). Therefore, this will give a direct assessment of honey production.
Answer:
Endosymbiosis of an oxygen-using scavenger bacterium in a larger host cell−the endosymbiont evolved into lysosomes.
Explanation:
The evolution of eukaryotic cells in all probability included: endosymbiosis of an oxygen-utilizing bacterium in a bigger host cell−the endosymbiont developed into mitochondria. development of an endomembrane framework and consequent advancement of mitochondria from a segment of the Golgi. endosymbiosis of an oxygen-utilizing photosynthetic bacterium in a bigger host cell−the endosymbiont advanced into mitochondria. endosymbiosis of an oxygen-utilizing scrounger bacterium in a bigger host cell−the endosymbiont developed into lysosomes.
Answer:
Uranus
Uranus' axis is tilted, so it rotates from top to bottom.
Answer:
C. II and IV only
Explanation:
X linked recessive inheritance follows the criss-cross pattern in which affected mothers always have affected sons as sons get their X chromosome from mothers only. Condition "II" can not be true for X linked inheritance as hemophiliac mothers (XhXh) should have hemophiliac sons (XhY) only.
Daughters get one copy of their X chromosome from the father and the other from mother. To have affected daughters, mother should be carrier or hemophiliac and the father should be hemophiliac (XhY). This would make it possible for both the parent to transmit one copy of X chromosome with the gene to daughters (XhXh).
