In response to viral infection, the immune systems of mice typically produce antibodies that destroy the virus by binding to pro

teins on its surface. Mice infected with a herpesvirus generally develop keratitis, a degenerative disease affecting part of the eye. Since proteins on the surface of cells in this part of the eye closely resemble those on the herpesvirus surface, scientists hypothesize that these cases of keratitis are caused by antibodies to herpesvirus.Which of the following, if true, gives the greatest additional support to the scientist's hypothesis?(A) Other types of virus have surface proteins that closely resemble proteins found in various organs of mice.(B) There are mice that are unable to form antibodies in response to herpes infections, and these mice contract herpes at roughly the same rate as other mice.(C) Mice that are infected with a herpesvirus but do not develop keratitis produce as many antibodies as infected mice that do develop keratitis.(D) There are mice that are unable to form antibodies in response to herpes infections, and these mice survive these infections without ever developing keratitis.(E) Mice that have never been infected with a herpesvirus can sometimes develop keratitis.

Answer:

(D) There are mice that are unable to form antibodies in response to herpes infections, and these mice survive these infections without ever developing keratitis

Explanation:

Option A: irrelevant, we do not care about other viruses.

Option B: There is no relation with keratitis.

Option C: This could mean that antibodies are not responsible for keratitis, so it does not support the hypothesis.

Option D (correcto answer): A lack of antibodies equals a lack of keratitis; this supports the argument that antibodies are involved in the development of keratitis.

Option E: misleading and does not support the hypothesis.

Identify and describe layer B in the figure above.
lukranit [14]
Based on the image, it seems that the picture is of the layers of the atmosphere. Now the B layer is the thermosphere. It is found in between the mesosphere (layer below) and the ionosphere (layer above). It extends up to 600 km high and you can find satellites and the aurora here. Temperature here is higher as the height increases and it is because of this trait, its name thermosphere was based on on. "Thermo," in Greek means heat. It overlaps with the ionosphere.

GREYUIT [131]
Cloning is a good idea because it replicates what we already have therefore genetically cloning something would lead to a better more functioning society. 
 
Genetic engineering is a good idea as well because it creates a stronger DNA that is less likely to get diseases such as Diabetes and cancer. As well as it leads us to a more utopian society and could possibly eliminate the need for breeding.

Which sequence best represents the levels of organization in a paramecium, a single-celled organism?
Agata [3.3K]

Answer:

D. organelles —› organism

Explanation:

Paramecium is a eukaryotic organism, which have a well-organized cell. Paramecium is a single-cell protist that have specialized membrane-bound organelles and nucleus that enable it to perform all life functions independently. These organelles are made up of atoms and macromolecules. The association of different unique organelles make up the paramecium which is a single-celled organism. “organelles —› organism” best represents the level of organization in a paramecium.
