To determine:
The use of animals in the drugs and cosmetic testing is correct or not.
Introduction:
There are many drugs and the cosmetics used by humans. The testing of these drugs and the cosmetics are done on animals to make sure it is safe for the human use.

Explanation of Solution
The drugs and the cosmetics are tested on the animals. There are many animals which have similar body reactions to the animals. Using of animals for the test is the only way to make sure that the drug is safe for humans and can be used. The use of animals is favored due to following reasons.
- The ease of study of harmful effect is easy in animals due to the social and the ethical issues.
- The number of model organism used are more as human population has high time of replacement as they give birth to a smaller number of offspring and the time taken is more.
- The effect of drug in the animals such as rats can be studied in different age groups and generations.

- Molecular Biology Question. Please help solve. Thanks. Please draw how two nucleotide triphosphates are linked together to form a dinucleotide, and label the 5' and 3' ends of the resulting dinucleotide.arrow_forwardWhat is a reversion in molecular biology?arrow_forwardWhat is a gain of function mutation?arrow_forward
- Molecular Biology Question: Please help. Thank you Is Southern hybridization's purpose detecting specific nucleotide sequences? How so?arrow_forwardUse the following information to answer the question(s) below. Martin Wikelski and L. Michael Romero (Body size, performance and fitness in Galápagos marine iguanas, Integrative and Comparative Biology 43 [2003]:376-86) measured the snout-to-vent (anus) length of Galápagos marine iguanas and observed the percent survival of different-sized animals, all of the same age. The graph shows the log snout-vent length (SVL, a measure of overall body size) plotted against the percent survival of these different size classes for males and females. Survival (%) 100- 80- 60- 40- 20- 0+ 1.9 T 2 2.1 2.2 2.3 2.4 2.5 2.6 2.7 Log SVL (mm) 19) Examine the figure above. What type of selection for body size appears to be occurring in these marine iguanas? A) directional selection B) stabilizing selection C) disruptive selection D) You cannot determine the type of selection from the above information. 3arrow_forward24) Use the following information to answer the question below. Researchers studying a small milkweed population note that some plants produce a toxin and other plants do not. They identify the gene responsible for toxin production. The dominant allele (T) codes for an enzyme that makes the toxin, and the recessive allele (t) codes for a nonfunctional enzyme that cannot produce the toxin. Heterozygotes produce an intermediate amount of toxin. The genotypes of all individuals in the population are determined (see table) and used to determine the actual allele frequencies in the population. TT 0.49 Tt 0.42 tt 0.09 Refer to the table above. Is this population in Hardy-Weinberg equilibrium? A) Yes. C) No; there are more homozygotes than expected. B) No; there are more heterozygotes than expected. D) It is impossible to tell.arrow_forward

Please help with step solution and explanation. Thank you: The Polymerase Chain Reaction (PCR) reaction consists of three steps denaturation, hybridization, and elongation. Please describe what occurs in the annealing step of the PCR reaction. (I think annealing step is hybridization). What are the other two steps of PCR, and what are their functions? Next, suppose the Tm for the two primers being used are 54C for Primer A and 67C for Primer B. Regarding annealing step temperature, I have the following choices for the temperature used during the annealing step:(a) 43C (b) 49C (c) 62C (d) 73C Which temperature/temperatures should I choose? What is the corresponding correct explanation, and why would I not use the other temperatures? Have a good day!arrow_forwardUsing the data provided on the mean body mass and horn size of 4-year-old male sheep, draw a scatterplot graph to examine how body mass and horn size changed over time.arrow_forward
