Hi, you've asked an incomplete question. The full question reads;

1. Identify the:

  • Control Group
  • Independent Variable
  • Dependent Variable

2. Explain whether the data supports the advertisement's claims about its product.

Answer:

  • <u>Subject A</u>
  • <u>The "certain itch powder"</u>
  • <u>The time of itchiness  </u>

Explanation:

1. Remember, the Control group in research often refers to the group in a research experiment that who are not subjected to any treatment, rather they are used as a comparison scale to see how other tested subjects perform.

  • We also need to note here that the independent variable here refers to a variable or factor that does not change (ie it is independent), but which results in changes in other variables. From the study, the "certain itch powder."
  • "The time of itchiness" is a dependent variable because it does change, or can be affected by the independent variable.

2. Remember, the advertisement of the "certain itching" <em>"claims to cause </em><em>50%</em><em> longer lasting itches".</em> Hence, we can conclude that the data support the advertisement claims since subject B did itch over 50% longer than subject A. In fact, we are subject B itched for 10 <u>hours,</u> not the 30 <u>minutes</u> subjet A itched.

ddd [48]

Answer:

The correct answer is - 25%

Explanation:

A cross between true tall pea plant and heterozygous tall pea plant is the cross of tall allele whic is TT and heterozygous which is Tt, so the gametes will be formed would be - T and T by true tall plant and T, and t allele by heterozygous plant.

The Punnett square of this cross is attached with the answer, where 2 heterozygous offspring and two tall offspring produced. In which there is only two recessive short allele formed in this generation out of 8 alleles.

So the probability of short allele would be:

= (2/8) *100

= (1/4) *100

= 25%
