I believe the answer is quite simple.

She must've compared the clothing washed with the new detergent with the old one. Jenny must've looked for stains, odour, etc. These would help determine whether or not the new detergent worked better.

Mendel's results demonstrated that diploid organisms have phenotypes, whereas haploid organisms have genotypes. phenotype is ind
kenny6666 [7]

Answer:

genotype is responsible for establishing phenotype

Explanation:

When Mendel experimented with pea plants, concept of genes and alleles had not come up yet. Through his experiments Mendel first proved that some type of combination in cells leads to a particular phenotype.

He coined the term "factors" which are today known as alleles. These factors paired up and displayed a particular phenotype. Today we know that the alleles are responsible for a genotype which ultimately results in a phenotype. Hence, he established that genotype is responsible for establishing phenotype even before the term genotype was coined.

​a client with hypovolemia has been prescribed intravenous fluid at 125ml/hr. the iv site to provide hydration has infiltrated.
Levart [38]

The following are the steps the nurse would take to treat the infiltrated site:  

1. Stop the infusion and remove the catheter

2. Elevate the extremity

3. Encourage an active range of motion

4. Apply a cold or warm compress depending on the solution infusing

5. Restart the infusion proximal to the location or in another extremity

Now, in order to address hydration requirements of the client, the nurse will have to begin a novel peripheral intravenous in another extremity or to again start the infusion if intravenous access has been created.
