No, it is not possible for them to have a child with dry earwax. In order for them to have a child with dry earwax, the child must have two recessive alleles in that trait. As the father is the only one who has one, there will be a 50% chance of heterozygous offspring, and a 50% chance of homozygous offspring in the dominant allele - no homozygous offspring in the recessive allele.
B.dominant
C.recessive
Dheterozygous
Large glass measuring cup (2 cups or bigger)
Blue food coloring
Vegetable oil (any type of cooking oil)
Liquid dish detergent
Procedure:
(4 points for each question)
Fill the cup two-thirds of the way with water. Add a few drops of blue food coloring to make your “ocean.”
Pour 1/3 cup of oil into the ocean.
Answer the following questions:
What happens to the oil when you first pour it in?
Why does this happen?
What kinds of animals would be most affected by an oil spill at the beginning? Why?
Use a spoon to stir the oil for 30 seconds.
Answer the following questions:
What natural action stirs the real ocean?
What happened to the oil?
Even if you can’t see it, is all the oil still in your ocean?
Which animals in the ocean become affected after wave and current action causes some of the oil to settle to the bottom, or be absorbed into the water?
Add a splash of dish detergent to the mixture and stir.
Answer the following questions:
What happened to the oil? Is it all still in the ocean?
Sometimes cleanup efforts involve dumping a soap mixture over a spill area. Why is this done?
What might be a negative effect of dumping the soap?
Submit this assignment to your teacher when you are finished.

Using the rock cycle, it shows that with heat and pressure, an igneous rock can turn into a metamorphic rock.
Explanation:
This is incorrect because it can also convert to sediments by weathering, erosion, and deposition. The Rock Cycle is a group of transformations. Igneous rock can transform into sedimentary rock or into metamorphic rock. Sedimentary rock can transform into metamorphic rock or into igneous rock. Metamorphic rock can convert into an igneous or sedimentary rock.
Answer:Natural selection is the process in nature by which organisms better adapted to their environment tend to survive and reproduce more than those less adapted to their environment.For example, tree frogs are sometimes eaten by snakes and birds. Gray Tree frogs blend well in dark wooded areas on tree bark and Green Tree frogs blend in well with green vegetation found in marshes and swamps. A Green Tree frog on the bark of a tree is easier for a predator to find, compared to a Green Tree frog on a green leaf. So, Green Tree frogs that go into habitats where they are not camouflaged are more likely to be eaten by predators. Since Tree frogs that have been eaten do not live to have any more baby Tree frogs, natural selection has favored Tree frogs that live in habitats in which they are more camouflaged.
Answer:
In a habitat there are red bugs and green bugs. The birds prefer the taste of the red bugs, so soon there are many green bugs and few red bugs. The green bugs reproduce and make more green bugs and eventually there are no more red bugs.
