SSA Quizziz #8: Heredity, Reproduction and Interdependence

[7.L.16.1] Some organisms reproduce sexually and have two parents. How does the genetic information of a new organism produced through sexual reproduction compare to the genetic information of its parents?

• It is an exact copy.

• It is completely different.

• It is opposite from its parents.

• It is a blend of the genetic information of its parents.

[7.L.16.2] For a particular trait, B is dominant to b. Which of the following genetic crosses would be expected to result in 50% of the offspring showing the phenotype of the dominant allele and 50% showing the phenotype of the recessive allele?

• BB x Bb

• Bb x Bb

• Bb x bb

• bb x bb

[7.L.17.2] The diagram below shows a mangrove food web.

Which pair of organisms in this food web competes for food?

• mangrove leaves and bacteria

• prawns and snails

• small fish and phytoplankton

• pelicans and snails

[7.L.17.3] Scientists recorded the size of a population of house finches in a forest ecosystem from the years 1995 to 2005. The graph below shows the information that was recorded.

What change in the limiting factors in the ecosystem could have caused the population

change that occurred between 2001 and 2002?

• food supply increased

• water supply increased

• number of nesting sites increased

• disease increased

[7.L.17.3] Panthers used to live all over the United States, but they moved out of areas as humans developed cities. Now, panthers are an endangered species that is found only in Florida.

What limiting factor has most impacted the panther population?

• Disease

• Predation

• Parasitism

• Space

[7.L.17.1] Food webs contain different kinds of organisms. How are all of the decomposers in a food web similar?

• They are all large animals that eat only consumers.

• They are all green plants.

• They all get energy by breaking down the remains of organisms.

• They all eat plants to get energy.

[7.L.17.1] Feeding relationships in an ecosystem are shown in a food web. Which best summarizes the relationship between producers and consumers in any food web?

• Consumers make their own energy by decomposing producers.

• Producers and consumers both get their energy from plants.

• Producers and consumers both get their energy directly from the Sun.

• Consumers get energy from producers.

[7.L.17.3] One limiting factor in an ecosystem is based on predation. The graph below shows how the numbers of wolves and rabbits in a forest changed over time.

Does the graph support the idea that wolves and rabbits have a predator-prey relationship?

• no, because there are more rabbits than wolves

• no, because the wolf population is too large to be fed by the rabbits and because the changes in rabbit population are more drastic than the changes in wolf population

• yes, because the rabbit population increases when there are fewer wolves

• yes, because the changes in rabbit population are more drastic than the changes in wolf population

[7.L.17.1] The diagram below shows a food web.Which of the following describes both the rabbit and the mouse in this diagram? 

• Both are primary consumers.

• Both are consumed by the fox.

• Both get energy from eating the meadow grass.

• Both are decomposers.

[8.L.18.2] According to the law of conservation of mass, matter is not created or destroyed during ordinary chemical processes. Instead, chemical reactions rearrange atoms into different chemicals. The word equation below summarizes the process of cellular respiration.Based on the information provided, what molecule provides the hydrogen that forms water during cellular respiration?

• Glucose

• oxygen

• carbon dioxide

• water
