Answer;
-Correlational; experimental
Two main types of designs used specifically in human lifespan studies are correlational and experimental.
Explanation;
-Psychological studies vary in design. In correlational studies a researcher looks for associations among naturally occurring variables, whereas in experimental studies the researcher introduces a change and then monitors its effects.
-An experiment isolates and manipulates the independent variable to observe its effect on the dependent variable, and controls the environment in order that extraneous variables may be eliminated. Experiments establish cause and effect. A correlation identifies variables and looks for a relationship between them.
The correct answer is C. A windstorm blew down trees in the Boundary Waters Canoe Area in Minnesota on July 4, 1999.
Explanation:
A weather event refers to a specific phenomenon in weather that in most cases is not common but particular and specific, which is different to weather patterns, this includes specific hurricanes, abnormal rain patterns, etc. Considering this, the one that is an example of a weather event is "A windstorm blew down trees in the Boundary Waters Canoe Area in Minnesota on July 4, 1999" because this is a specific phenomenon rather than a pattern in weather as int the case of hurricane seasons or permanent weather conditions.
Answer:
75% of their offsprings will be red birds, and 25% will be with birds, this is the phenotype.
The genotype will be BB, Bb, and bb.
Explanation:
he information that we have is that B is the dominant allele for red feathers in a bird, and b is the recessive allele for white feathers in a bird.
If we cross two heterozygous birds that means that both progenitors are Bb, if we draw a Punnet Square we can see that 75% of the offsprings will be red birds, and 25% will be white birds, this is the phenotype, which is what we can physically see of the genes.
The genotypes will be BB, Bb, and bb, these are the different combinations of genes that can happen, and that explains why a bird is red or white, which is due to the dominance of one allele over the other.
<u> ║ B ║ b ║</u>
<u>B║ BB ║Bb ║</u>
<u>b║ bB ║ bb ║</u>
Answer:
here are four basic cost behavior patterns: fixed, variable, mixed (semivariable), and step which graphically would appear as below. The relevant range is the range of production or sales volume over which the assumptions about cost behavior are valid. Often, we describe them as time-related costs.
Explanation:
The general types of cost behavior fall into three categories. First is variable costs, which vary directly with changes in business activity. For example, there is a specific direct materials cost associated with each product sold. Second is fixed costs, which do not change in response to business activity levels.
