Answer:

B. Genetically engineered mammalian cells

Explanation:

Herceptin is a monoclonal antibody that binds (attach) to specific antigens in cancer cells to destroy them. This antibody is used in the treatment of different types of cancers including breast and gastric carcinoma, in which HER2/neu protein is overexpressed. Herceptin targets HER2/neu receptors present in cancer cells to kill them. HER2/neu is a protein signaling receptor involved in cell proliferation, thereby this antibody works to selectively target cells that have an excess of HER2/neu receptors such as gastric and breast cancer cells.

When an automatic battery is fully charged the sulfuric acid and water mixture will have a specific gravity of about
Archy [21]

the specific gravity of pure sulfuric acid is---------> approximately 1.835 g / cm3

the specific gravity of water is -------------------- >1.000 g / cm3.

 The electrolyte, that is, the dissolution of sulfuric acid in water, is usually at a rate of 36% acid, so that, in a fully charged element, we can deduce the electrolyte density, is 1.295 g / cm3. (see attached table)

The specific gravity is actually the difference in the weight of water compared to a specific fluid. It is measured with a hydrometer

crimeas [40]

Answer:

50%

Explanation:

Both parent's genotype is Bb because they are hairless and alive.

If it has a homozygous dominant genotype (BB), the dog will die in utero.

If it has a heterozygous genotype (Bb), the dog will be hairless but won't die.

If it has a homozygous dominant genotype (bb), the dog will have hair.

The ratio of BB:Bb:bb is 1:2:1 meaning that there is a 50% probability of having a live hairless puppy.

Hope this helps! <3
