Answer:
IV: Student grade level (6th, 7th, 8th)
DV: "Loudness" (Operationalizing this variable would be beneficial, or in other words, define a way to measure it)
Explanation:
Plants and some types of archaea or bacteria use photosynthesis to create food.
Hello. You forgot the results of Courtney's observations. The observations are:
"Tendril # Week 1 Week 3 Week 6
1 1.2 cm 5.9 in 1.2 ft
2 2.0 cm 4.8 in 0.98 ft
3 0.8 cm 3.2 in 0.55 ft
4 0.2 cm 1.6 in 0.35 ft
5 1.5 cm 4.3 in 1.01 ft"
Answer:
Curtney's data show inconsistent units of measure.
Explanation:
Measurement units are ways of representing great physics such as speed, size, time, quantity, weight, among others. These units serve to quantify the matter and allow observations to be made.
It is important to note that the same units of measurement must be evaluated in the same experiment. For example, if we want to evaluate how much a plant can grow in 3 weeks, we have to evaluate the same unit of measure each week. If in the first week we evaluate the growth in centimeters, we have to evaluate the growth in the next weeks also in centimeters.
Courtney did not do this, and assessed the growth of the plants each week with different units of measure, which left her data inconsistent.

Answer:
Gene flow is partially responsible for <u><em>genetic variation</em></u>.
Explanation:
In ecology, gene flow can be described as the transfer of genes from one population of a species to another population of a species. Gene flow will result in the changing of the allele frequency of a population. As a result of gene flow, there will be more genetic variation among the population. Gene flow is also termed as gene migration. The gene flow causes the gene pool of a population to change.
