Answer: B) It controls the autonomic nervous system and regulates hunger and thirst sensations.
Oblique signifies anything that is not at right angle to something. So, an oblique cut is one, which is not perpendicular to the side that it intersects.
In anatomy, an oblique cut refers to a diagonal cross-section achieved by slicing the part of the body or the anatomic composition, in any plane, which does not intersect it at a right angle, or does not parallel the longitudinal axis, that is, neither transverse (horizontal) nor longitudinal (vertical).
Answer:
0.8 and 0.2
Explanation:
Hardy Weinberg law states that the allele frequency of the population remain stable from one generation to next generation if no natural selection, drift or mutation occurs in the population.
Let p and q be the dominant and recessive frequency of the population respectively.
The dominant phenotype means p² = 0.64
p = 0.8
and we known that p + q = 1, in hardy Weinberg equilibrium.
0.8 + q = 1.
q = 0.2
Thus, the dominant allele is 0.8 and recessive allele is 0.2.
Answer and Explanation:
To test the presence of glucose, we can perform <u>Benedict's test.</u> This test detects the presence of reducing sugars (e.g. glucose) by adding <u>Benedict's reagent.</u> This reagent contains sodium carbonate, sodium citrate and copper(II) sulfate pentahydrate. When the mixture is heated, reduce cupric compounds (Cu2+) are formed which results in the change in color from clear blue to brick-red, yellow or green.
To test the presence of glucose in the food sample, we will dissolve a small volume of food sample in water and put it in the test tubes, in triplicates. Then we will add 3 mL of Benedict's reagent. Also, we will run positive and negative controls. For positive controls, we will add glucose directly and for negative, we will not add any glucose or other reducing sugars (also in triplicates each). Then we will heat the test tubes in water water for 5-10 minutes. In the positive control, the color would change to green, yellow or brick red; but in negative control, it will stay blue (see figure attached for explanation). For the food sample, if the glucose or reducing sugars would be present, the color will change. In case of low sugar, it will be green, but increasing sugar content would change the color to yellow/orange and red. Because the experiment will be conducted in triplicates, we would be also able to verify if the results were consistent and there was no human or technical error.
