Question

question 1
using the information below, and based on your knowledge of enzymes - which independent variable would be a good starting point to determine the cause of the poor result?
read the paragraph below and answer the questions that follow.
youre the manager of a factory that produces enzyme - washed blue jeans (the enzymes lighten the color of the denim, giving a \faded\ appearance). when the most recent batch of fabric came out of the enzyme wash, however, the color wasnt light enough to meet your standards. your quality control laboratory wants to do some tests to determine why the wash enzymes didnt perform as expected.

a the color of the jeans after the enzymes did their work.

b the education of the quality control team.

c the number of people working in the factory

d the temperature of the wash vat where the enzymes are added.

question 2
english ivy is a plant that has the ability to grab onto objects and grow upward to get sunlight. this same ivy can also be found growing flat along the ground. what causes the variation in the ivy growth?

a the ivy, that grows upward, has nearby objects to climb, and is exhibiting thigmotropism.

b the ivy, that grows flat but has nearby objects to climb, and is exhibiting gravitropism.

c the ivy grows where it will be able to blend into its environment to avoid predation.

d the ivy grows where it will receive the least amount of sunlight for photosynthesis.

Explanation:

For Question 1, enzyme activity is highly influenced by environmental factors like temperature. The color of jeans after the process is a dependent variable, the education of the quality - control team and the number of factory workers are not relevant to enzyme performance directly. For Question 2, thigmotropism is the growth response of a plant to touch or contact. English ivy growing upward when there are nearby objects to climb shows thigmotropism. Gravitropism is related to response to gravity, blending into the environment for predation avoidance and growing for least sunlight are not the main reasons for the upward - flat growth variation here.

Answer:

Question 1: d. The temperature of the wash vat where the enzymes are added.
Question 2: a. The ivy, that grows upward, has nearby objects to climb, and is exhibiting thigmotropism.
