Describe two ways that people contribute to the spread of antibiotic resistance.

People contribute to <span>antibiotic resistance by not completing their full course of antibiotics as prescribed by doctors when they are sick. This allows the bacteria to adapt to the antibiotic because the incomplete treatment did not kill the bacteria. Another way in which bacteria are becoming resistant to antibiotics is the widespread use of antibiotics in everyday consumer products, such as cleaners and beauty products. These antibiotics end up in the environment, and diluted exposure to these antibiotics by bacteria allows the bacteria to develop a resistance.   </span>

Compared the Mendelian Dominance, how to incomplete dominance and codominance increase the number of phenotypes? Provide an exam
REY [17]

Answer/Explanation:

<h3>Incomplete dominance</h3>

In incomplete dominance, one allele is not entirely dominant over the other, so heterozygotes (organisms with two different alleles for the gene) show an intermediate or blended phenotype.

For example, consider flower colour.

  • If the allele for red flowers (R) was dominant over the allele for white flowers (r), then there are three possible genotypes (RR, Rr, and rr) and two possible phenotypes. (Red (RR and Rr) and white (rr)).
  • However, if the allele for red flowers (R) was incompletely dominant over the allele for white flowers (r), then there are three possible genotypes (RR, Rr, rr), and three possible phenotypes (red (RR), white (rr), and pink (Rr))
<h3>Co-dominance</h3>

In incomplete dominance, two alleles are both expressed, one is not dominant over the other. Therefore, heterozygotes (organisms with two different alleles for the gene) express both traits.

For example, consider flower patterns.

  • If the allele for spots (F) was dominant over the allele for stripes (f), then there are three possible genotypes (FF, Ff, and ff) and two possible phenotypes. (Spots (Ff and ff) and stripes (ff)).
  • However, if the allele for spots (F) was co-dominant to the allele for stripes (f), then there are three possible genotypes (FF, Ff, ff), and three possible phenotypes (spots (FF), stripes (ff), and spots and stripes (Ff))

suppose you balanced a sample against three 10-gram masses. Suppose the sample weighed a little more than three masses, but coul
alexdok [17]

Answer: 241.5

Explanation:

Move the slider on the 100 gram beam to the first mark on the right, which is the 100 gram mark. If the pointer still is above the central mark, continue to move the slider to the right. Once the pointer drops below the central mark, move the slider back to the previous mark to the left. If the pointer drops below the central mark at 100 grams, move the slider back to zero.

Move the slider on the 10 gram beam to the 10 gram mark. Perform the same adjustments you did in the previous step until you find the appropriate slot for the 10 gram slider.

Repeat the same process with the 1 gram slider.

Add the values from each slider. For instance, if the 100 gram slider is on 200, the 10 gram slider is on 40 and the 1 gram slider is on 1.5, you would add 200 plus 40 plus 1.5 to get a total of 241.5 grams as the mass of your object in the tray.
