She should have to classify this animal under pseudocoelomates category. The body cavity of these animals are filled with fluids. Internal organs are covered by the fluid filled space. The body cavity serves as the hydrostatic skeleton and have other functions such as digestion of food and waste removal.
The only one that makes sense is size. because there could be other minerals the same size. so size wouldn't be a property to help identify
Answer:
Western blot should be performed
Explanation:
Generally ELISA test is sensitive to elevated antibodies levels in the blood. Because HIV infection is characterise with increases in antibodies levels(HIV-antibodies levels)of the body, it is usually the first screening test for HIV,however it is also sensitive to elevated antibody from any other infection apart from HIV. Therefore for confirmation, the procedure is to run a second ELISA test, to determine if the antibody rise was due to HIV or not. If the second test turns positive, then Western blot can be applied.
The Western blot through secondary and primary antibodies binding , separates the investigating antibodies, and identity the specif HIV antibodies present to give a positive HIV-antibody, confirming ELISA positive test.
Thus for confirmation of HIV specific antibodies of the blood; ELISA test followed by Western blot is ideal
Answer:
A
Explanation:
Answer is A because, production of gametes happens in meiosis. So, the first splitting of one cell into two daughter cell occurs in telophase I and then in each of these daughter cells in meiosis II those sister chromatids separate into full fledged chromosome and each daughter cell splits into two different cells. So at end you have 4 new non-identical daughter cells.
