The ability to roll the edges of the tongue upward in a U-shape has been considered to be an inherited ability. The standard assumption is that tongue-rolling is a dominant allele at a single gene locus. Which of the following would cast doubt on this assumption?
A)A teacher reports that after testing her class on the ability to roll their tongue, with very little effort the non-tongue-rollers can learn to also roll their tongues.
B)A student who can roll his tongue has a mother and father, both of whom cannot. C)A student who cannot roll his tongue has a mother and father, both of whom can.
D)The non-tongue rollers who learn to roll their tongues and the student who can roll his tongue while his parents cannot are two situations that cast doubt on the heritability issue. The situation where a student cannot roll his tongue while his parents can is inconclusive.
E)Behaviors are not inherited, only structures are inherited.
Answer:
D)The non-tongue rollers who learn to roll their tongues and the student who can roll his tongue while his parents cannot are two situations that cast doubt on the heritability issue. The situation where a student cannot roll his tongue while his parents can is inconclusive.
Explanation:
This is because non tongue rollers who learn to roll their tongues appears to negate the idea of tongue rolling ability to be inherited ability, while also the fact that non tongue rollers having parents who cannot roll their tongues also prove the idea that tongue rolling ability is hereditary.
Hence, the option D)The non-tongue rollers who learn to roll their tongues and the student who can roll his tongue while his parents cannot are two situations that cast doubt on the heritability issue. The situation where a student cannot roll his tongue while his parents can is inconclusive, will surely cast doubt on the assumption, that rolling of tongue is an ability that is hereditary
The pesticides are exempt from the notification, posting and reporting requirements of the healthy schools act are "Exempt pesticide".
<h3>
What is Healthy Schools Act (
HSA)?</h3>
The Healthy Schools Act in California specifies obligations for school & child care center workers, pest control experts, and the Department of Pesticide Regulation when pesticides are applied at those locations.
Some key features of HSA are-
- The statute was initially enacted by the California Legislature in 2000.
- A Healthy Schools Act also promotes the use of integrated pest management (IPM), often known as effective, low-risk pest management strategies, in schools and child care facilities, collectively referred to as schoolsites.
- Efficient, low-risk pest management techniques are the emphasis of integrated pest management, called IPM.
- IPM is a holistic approach to insect control that takes into account both the environment and humans when making pest control decisions.
- IPM techniques come in many forms, such as routine cleaning, gap closure, pipe repair, trap setting, and low-risk pesticide selection.
- All school sites can effectively manage pests with the quantity of IPM knowledge provided today and an active IPM leader!

Answer:
Type of support surface
Nutritional supplementation
Explanation:
Variable
This is simply an element, feature, or factor that is prone to change or be altered. There is the independent and the dependent variable.
An Independent variable
This is simply refered to as a variable that is deliberately altered or changed to observe its effect on the dependent variable. It is that variable that a researcher or a scientist alters or changes and you have control over. They are the factor being tested in an experiment.
An example is the liquid used to water each plant in an experimental studies.
