Hershey and Chase used a DNA-based virus for their work. How might the results have been different if they had used an RNA virus
4vir4ik [10]

Answer:

The correct answer is c.With an RNA virus, radioactive RNA would have been in the final pellet.

Explanation:

Hershey and Chase infected<em> E.coil</em> with bacteriophage which was having DNA as its genetic material. The bacteriophage was labeled with radioactive sulfur and radioactive phosphorus and it was radioactive phosphorus that was found in the bacterial cells or pellet.  

As because DNA contains phosphorus, not protein therefore they it was proved that DNA is the genetic material. Similarly, RNA is also a nucleic acid which is genetic material for many viruses and contains phosphorus.

So if Hershey and chase might have chosen an RNA virus then radioactive RNA would have been present in the pellet. So the correct answer is c.

A person who has cerebrospinal fluid draining from the ear probably has a fracture of the temporal bone.

<h3>What is Cerebrospinal Fluid?</h3>

All animals have cerebrospinal fluid (CSF), a transparent, colorless bodily fluid that is present in the tissue that covers their brains and spinal cords.

Specialized ependymal cells in the choroid plexus of the brain's ventricles create CSF, which is then absorbed in arachnoid granulations. About 125 mL of CSF are present at any given moment, and 500 mL are produced daily. The CSF protects the brain inside the skull mechanically and immunologically by acting as a shock absorber, cushion, or buffer. The cerebral autoregulation of cerebral blood flow is another essential role played by CSF.

The ventricular system and subarachnoid space, which are located surrounding and inside the brain and spinal cord, respectively, are occupied by CSF.

GIVING BRAINLIEST second stage of mitosis
PolarNik [594]
What Happens during Prometaphase? When prophase is complete, the cell enters prometaphase — the second stage of mitosis. During prometaphase, phosphorylation of nuclear lamins by M-CDK causes the nuclear membrane to break down into numerous small vesicles.

A wave front has the form of a
madreJ [45]

The rigth answer is D.

The wavefront or wavefront is an equal phase surface of a wave, i.e., these points have the same travel time from the source. The concept is used to describe the propagation of waves such as sound or electromagnetic radiation (light, radio waves, etc.). In a homogeneous and isotropic medium, in which the waves propagate without deformation, two types of particular waves are distinguished according to whether the wavefronts are spheres (spherical wave) or planes (plane wave).
