PMA 3 Review #3

While observing a litter of puppies, Amy and Jose noticed that the puppies had a variety of black and white coat colors. They knew that the puppies had the same parents and that all of the puppies were from the same litter. Which of the following best explains why these puppies had different coat colors?

• The puppies receive an exact copy of both parents' DNA.

• The puppies randomly receive DNA from only one of their parents.

• The puppies coat color is random and not influenced by their parents.

• The puppies receive different combinations of DNA from both of their parents.

How do the structures in the image play a role in heredity?

• DNA produces genes which are types of cells located in the chromosome.

• Chromosomes contain DNA where the genes that store the information about our traits are located.

• Genes determine the type of DNA we will receive from our parents which is located on our chromosomes.

• Chromosomes produce DNA when reproduction occurs and from there genes are passed to the next generation.

Scientists were studying a species of fish and began their research by placing four adult fish, two males and two females, into a fish tank. Overtime, these fish reproduced and the tank became filled with fish. Before moving some of the fish to a new tank, the scientists decided to test the DNA of the fish to determine who they were related to. The table shows the percentage of DNA that the new fish had in common with the four original adult fish.

Which of the following can be concluded from the information shown in the table?

• Fish 1 and Fish 3 share the same parents.

• Fish 1 and Fish 4 share the same parents.

• Fish 1 and Fish 2 share no genetic information.

• Fish 2 and Fish 3 share some genetic information.

Aphids are small insects that live on various types of plants and feed on their sap. When there is a large population of aphids occupying a plant, they may remove too much sap causing the plant to change color or wilt. Ladybugs eat aphids and are often used greenhouses to control the aphid population. Which type of relationship exists between the aphids ladybugs and plants?

• The relationship between the ladybugs and aphids are an example of competition.

• The ladybugs and aphids are an example of predation while the aphid and plants are an example of parasitism.

• The ladybugs and plants are an example of mutualism while the aphid and plants are an example of parasitism.

• The aphids and plants are an example of commensalism while the ladybugs and plants are an example of predation.

Gopher tortoises dig their homes called burrows in well-drained sandy soils throughout the southeast. These burrows are sometimes used by the Florida pine snake and eastern diamondback rattlesnake as a refuge from weather or fire. Which of the following relationships is most similar to the relationship between the gopher tortoise and the snakes?

• A Pseudoscorpion is a tiny scorpion with no stinger that moves from place to place by hitching a ride on much larger insects

• Tapeworms live in the digestive system and eat partially digested food which eventually deprives the host of food and nourishment.

• The goby fish and blind shrimp live in a burrow in the sand created by the shrimp and when a predator is near the goby fish will touch the shrimp to warn it.

• Moths lay eggs in the seedpods of the yucca plant, the larvae hatch and feed on some but not all of the seeds and the moth acts as a pollinator for the plant.
