Answer:

D. Ship ballast

Explanation:

Zebra mussels are the invasive species that have adaptive features to allow them to invade the new ecosystems. They have floating larva that can be transported along with running water. Also, the adult form of zebra mussels have ability to attach themselves to various substrates such as boats and ship ballasts. The primary factor for introduction of the species in Great Lakes is attachment of the species to the ship ballast that enter the lake.

KIM [24]

Answer: The video shows the plant reacting to external stimuli. Humans also react to many types of external stimuli. If someone touches us when we’re not expecting it, we jump. If we put a hand on something hot, we snatch it away. When it’s cold outside, our bodies shiver and our skin turns cold. When we walk into the sunlight after being in the shade, we tend to close our eyes or squint.

Answer:The correlated trait exercise shows that when two characters are correlated, the optimal values and selection strengths rise and fall together.

Explanation: Correlation refers to statistical (linear) relationship between two random variables. When traits are correlated, change in one is associated with change in the other.

Correlation coefficient (c.c.) measures strength of association between two variables in the same individual or experiment. It can range from -1 to +1. C.c. can be positive, negative or weak.

1. A positive c.c. means that an increase in one variable is associated with an increase in the other variable.

2. A negative c.c. means that an increase in one variable is associated with a decrease in the other.

3. A c.c. near zero indicates a weak relationship between the variables.

Correlation can be represented by scatter plot as shown in the attached image.
