One group of students studied with the TV on. Another group of students studied in silence. Students were then given a quiz to check for understanding.What is the independent variable in this experiment and what is the dependent variable?

Answers

Answer 1
Answer:

Answer:

independent variable: studying atmosphere

dependent variable: understanding of quiz

Explanation:

The independent variable refers to the variables that are directly supplied by the researcher during the course of an experiment whose manipulatory effects are measured on the dependent variable. In other words, independent variables are variables that are directly manipulated during experiments.

The dependent variables on the other hand refer to the main variable a researcher sets out to determine during an experiment. The value of the dependent variable is determined by the inputted independent variable by the researcher.

In the illustration, the manipulated variable is the studying atmosphere of the students - silent atmosphere or atmosphere with the TV switched on. The main variable that the researcher wants to determine is the understanding of the given quiz.

Hence, the independent variable is the studying atmosphere of the students while the dependent variable is the understanding displayed by the student.

In a plant, a single locus affects both berry color and berry size. There are two mutant alleles (R1 and R2) in addition to the wild-type allele (R0). Individuals that are R0R0 have large, white berries. Individuals that are R1R1 or R0R1 have red berries, individuals that are R2R2 or R0R2 have small berries, and R1R2 individuals have berries that are both red and small. Thus...R1 is dominant to R2.R2 is dominant to R1.R1 and R2 exhibit incomplete dominance.R1 and R2 exhibit codominance.R1 and R2 exhibit pleiotropy.

Answers

Answer:

R1 and R2 exhibit codominance.

Explanation:

In the given plant, pleiotropic locus regulates both berry color and berry size. The R1 allele gives red berries while the R0 allele is responsible for white berries. The heterozygote R0R1 also has red berries, which means that R1 is dominant over R0 for the color of berries. The R2 allele is responsible for the "small" size of berries in homozygous genotype.

The genotype R0R2 also has small berries, which means that R2 is also dominant to R0. However, the genotype R1R2 imparts red color and small size to berries. In the genotype R1R2, both the R1 (responsible for the red color of berries) and R2 (responsible for the small size of berries) alleles are expressed. This represents the fact that the R1 and R2 alleles are codominant and express themselves in heterozygous R1R2 genotype.

Which of the following statements about physical models is not true?a. Physical models are often three-dimensional representations.
b. Physical models are used to represent an object or event.
c. Physical models are usually in the form of a graph.
d. Physical models can be used to depict microscopic objects

Answers

c. Physical models are usually in the form of a graph.

Physical models represent and display certain paradigms and theoretical representations of how one mechanism functions or what is the components that make up an object, for instance. Hence, these aid scientists and other learners to have an overview of that is currently on the process.

Water is most likely to be condensing when we observe which of the following atmospheric conditions?. A. a heavy rainstorm.
B. a very cloudy sky.
C. a clear sky.
D. a light snow.

Answers

Answer: B. a very cloudy sky

Condensation is a process in which the gaseous form of water is converted into liquid. It is very important for the water cycle. This results in the formation of the clouds, fog and dew. For the occurrence of condensation, the air must be saturated. Saturation occurs most commonly when the warm air in the atmosphere cools down to it's dew point. The condensed water vapors and some of the particular matter forms the clouds.

Answer: B

Condensation is a process via which a liquid directly converts to a gaseous state, skipping the liquid state altogether. Therefore, a very cloudy sky is an example of water being converted to gaseous state directly.
