Answer: D
Explanation: you got the one you click on right so no changes needed.
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.
Answer:
Option (A)
Explanation:
Fungus are the unicellular eukaryotic living organisms that are so small that it cannot be seen with our naked eye. It plays a significant role in decomposing the dead plants, animals, and other organic matters. They are present in both terrestrial as well as the aquatic environment.
<u>Fungus are most closely related to the animals</u>, because they both have similar characteristics.
Fungus cannot prepare their own food like animals and they are considered to be heterotrophic. They can reproduce by the means of spores and their cells are comprised of nuclei with various numbers of chromosomes. These are the first unicellular organisms on earth from which the evolutionary processes has taken place and formed the present day complex multi-cellular organisms.
Thus, the correct answer is option (A).
