Sign an experiment.
expeople1 [14]

The answers to the questions required for the design experiment above are :

  • If shark attack are related to the number of elephant seals in an area, then shark attack will increase as the number of elephant seal increases

  • If shark attack are unrelated to number of elephant seal in an area, then shark attack is unaffected by increase or decrease in number of elephant seal.

  • The Control Group : Beaches or areas where elephant seals aren't present or period of the year when there are no elephant seal at the beach.

  • The Experimental group : Beaches where varibale portions of elephant seals are found (area with high, medium or low).

  • The Dependent variable : Number of shark attacks

  • The Independent variable : The different number of elephant seals found.

  • Data to be collected include : The number and type of elephant seals found at various beaches and the number of shark attacks recorded at the various points.

  • John will be able to deduce if the number of elephant seals and number of shark attacks recorded corded are related.

The hypothesis of an experiment is a proposition which requires experimental testing in other to establish it's validity.

The Control Group refers to a portion of the subject which aren't given or exposed to the treatment used in an experiment.

The Experimental group are the portion of the subjects which are subjected to the treatment condition.

The Dependent variable is the measured variable is changes as the independent variables are tweaked.

Independent variable is the predictor variable, it causes a change in the output of the dependent variable.

Consider the following three populations of birds. Assume HW equilibrium. With these birds red coloring is recessive, while brow
bixtya [17]

Answer:

Red allele frequency will be highest in population II

Population III can undergo bottleneck effect

The frequency of the brown allele will  least likely be altered in the population I

Explanation:

Population I -

Total population - 670

Brown birds - 603

Red birds - 67

Population II

Total population - 100

Brown birds - 90

Red birds - 10

Population III

Total population - 30

Brown birds - 27

Red birds - 3

Frequency of red birds in population I

\frac{67}{670} = 0.1

Frequency of red birds in population II

\frac{10}{90} = 0.11

Frequency of red birds in population III

\frac{3}{30} = 0.1

Red allele frequency will be highest in population II and it will be equal to \sqrt{0.11} = 0.33 as compared to 0.31 in case of population I and III

Population III can undergo bottleneck effect because of smaller population size

The frequency of the brown allele will  least likely be altered in the population that has highest  brown individual , i.e population I
