Answer:
If there is low genetic diversity, she needs to introduce something into the system to increase the variation. I would suggest breeding the orange trees with other new orange trees to change the allele frequencies, which is called gene flow.
Likely the fungi are attacking them somewhere that they have decreased resistance, and if more alleles were introduced, there would probably be evolution towards a genotype that promotes defense against these fungi.
Answer:
These are the 9 limitations in science.
•Must deal with observable measurable phenomenon.
•Science can describe not explain.
•No experiment can be completely controlled.
•Observations may faulty.
•A mans belief effects his judgment.
•Science must deal with repeatable results.
•Science cannot deal with values or morals
•Science cannot prove a universal statement.
•Science cannot establish variable.

Answer:
someone get because it present in an X-linked recessive pattern
Explanation:
Boy inherits an X chromosome from his mother and a Y chromosome from his father, and girls get two X chromosomes, one from each parent
a. When sensory information is detected by a sensory receptor, sensation has occurred. TRUE
For example, light that enters the eye causes chemical changes in cells that line the back of the eye. These cells relay messages, in the form of action potentials, to the central nervous system.
b. All sensory systems have absolute and difference thresholds. FALSE
Absolute threshold refers to the minimum amount of stimulus energy that must be present for the stimulus to be detected 50% of the time.
c. Sensory receptors are specialized neurons that respond to specific stimuli. TRUE
d. Sensation refers to the way sensory information is organized, interpreted, and consciously experienced. TRUE
Sensation is input about the physical world obtained by our sensory receptors, and perception is the process by which the brain selects, organizes, and interprets these sensations.
