Question 1

According to the text,what variable in an experiment is measured to calculate the results of the experiment?

Accepted Answer

The dependent variable is the variable that is being measured in an experiment. It is the variable that is affected by the independent variable, which is the variable that is being manipulated in the experiment. The extraneous variable is a variable that may affect the results of the experiment but is not being intentionally manipulated. The control variable is a variable that is kept constant throughout the experiment to ensure that any changes in the dependent variable are due to the independent variable.

Question 10

____ twins have exactly the same genes,whereas ____ twins have about half their genes in common,the same as other siblings.

Monozygotic twins, also known as identical twins, come from a single fertilized egg that splits into two embryos, so they have exactly the same genes. Dizygotic twins, also known as fraternal twins, come from separate eggs fertilized by separate sperm, just like other siblings, so they share about half their genes in common.

Question 11

Accepted Answer

Homo sapiens had smaller jaws compared to earlier Homo species. This is thought to be a result of changes in diet and the use of tools, which led to a reduced need for strong jaw muscles.

Question 12

According to the text,what variable in an experiment is different for the experimental group than for the control group?

Accepted Answer

The independent variable is the variable that is manipulated or changed in an experiment in order to observe its effect on the dependent variable. It is the one variable that is different between the experimental group (where the independent variable is present) and the control group (where the independent variable is absent or held constant). Therefore, the correct answer is D - independent variable.

Question 13

Which of the following occurred during the Neolithic period?

Accepted Answer

During the Neolithic period, humans began to domesticate animals and practice agriculture, leading to more settled communities.

Question 14

A ____ is a situation that exists naturally but that provides interesting scientific information to the perceptive observer.

Accepted Answer

A natural experiment is a situation that already exists in nature, without manipulation by the researcher, but provides valuable scientific information. It allows for the observation of natural phenomena and the identification of cause-and-effect relationships. The other options (holistic experiment, random experiment, quasi-experiment) involve some form of manipulation by the researcher.

Question 15

What condition did the individuals in the experiment discussed in this video have?

Question 16

Which of the following best represents the impact of evolution on human development?

Accepted Answer

Evolution has certainly played a role in shaping human biology, but the impact of culture cannot be overstated. Cultures have molded humans into widely different paths throughout the life span, resulting in a diverse range of behaviors, beliefs, and practices. Bipedal locomotion is certainly a defining characteristic of our species, but it is just one aspect of our biology. Instincts do not necessarily reduce humans' capacity for cultural learning, as cultural learning is itself an adaptive strategy that has allowed humans to thrive in a wide range of environments.
