Answer:

The second option.

Explanation:

We're trying to test the amount of bleach that has an effect on the stain so that is the altered variable.

The 2nd option uses different amounts of bleach to clean the same amount of stain.

If you choose the other options, people can argue that the bigger stain would be harder to clean with one cup of bleach, whereas the small stain gets two cups or the other way around.

It's not an effective way to see if the amount of bleach has an effect on stain removal.

<span>Streptococcus is a genus of coccus (spherical) Gram-positive bacteria belonging to the phylum Firmicutes[3] and the order Lactobacillales (lactic acid bacteria). Cell division in this genus occurs along a single axis in these bacteria, thus they grow in chains or pairs, hence the name—from Greekstreptos, meaning easily bent or twisted, like a chain (twisted chain). Contrast this with staphylococci, which divide along multiple axes and generate grape-like clusters of cells.)</span>

Which description is an example of codominance
xxMikexx [17]

Answer:

Explanation:

Codominance means that neither allele can mask the expression of the other allele. An example in humans would be the ABO blood group, where alleles A and alleles B are both expressed. So if an individual inherits allele A from their mother and allele B from their father, they have blood type AB.
