Which statements about kinetic energy are true? It's always transformed into potential energy. It's always associated with motio
Fittoniya [83]

Answer:

It's always associated with motion

It can be transferred from one object or body to another

Explanation:

Kinetic energy is the energy due to motion of a body.

  • Moving objects possess kinetic energy which is resident in that body.
  • As with other forms of energy, it can be transferred from one body to another.
  • Kinetic energy can express itself as thermal energy, electrical energy, mechanical energy etc..
  • As a body moves, the kinetic energy is increases.

A client with suspected human immunodeficiency virus (HIV) has had two positive enzyme-linked immunosorbent assay (ELISA) tests.
victus00 [196]

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

Three-carbon molecules of PGA are converted to G3P small sugar molecules by _____, which come from the light reaction. ADP and N
True [87]

Answer:

ATP and NADPH

Explanation:

The second stage of the Calvin cycle is the reduction in which 3-Phosphoglycerate is reduced into Glyceraldehyde 3-phosphate by a series of reactions. These reactions consume ATP as an energy source and NADPH as an electron donor. ATP and NADPH for produced during the light-dependent phase of photosynthesis. Transfer of electron through ETC generates proton concentration gradient across the thylakoid membrane which in turn drives ATP synthesis. Electrons released from water splitting finally reach NADP reductase enzyme that reduces NADH into NADPH.
