Onions can reproduce from bulbs. One parent bulb generates daughter bulbswith duplicate genetic information. Which is the most likely advantage of this kind of reproduction?
Beneficial mutations are in evitable.
Population size remains constant.
Genetic variation is maximized.
Many offspring are produced rapidly
A species of mouse spends the day sleeping in its burrow to avoid high daytime temperatures. It is processing what little water it needs from the seeds it collects. To which environment is this mouse BEST adapted?
rainforest
desert
marine
tundra
If an environment becomes warmer and drier, the change that would most likely help a species adapt would be an increase in its
amount of body fat.
ability to store water.
amount of body hair.
ability to climb trees.
Based on the key above, which of these plants is a gymnosperm?
Within a cave environment, bat waste products, called guano, are decomposedby organisms such as fungi and bacteria. These are then eaten by creatures such asflatworms. Larger animals like salamanders eat flatworms. Which correctly represents the energy flow described?
Fungi → Bacteria → Salamanders → Guano
Guano → Bacteria → Flatworms → Salamanders
Salamanders → Fungi → Bacteria → Flatworms
Bats → Guano → Flatworms → Salamanders
Which is the best prediction of what might happen to the moth population over time?
The lighter-shaded moths will become darker-shaded.11
The darker-shaded moths will be selected out of the population.
The lighter-shaded moths will be selected out of the population.
The shades will have little or no effect on the moth population.
The sound made by crickets occurs when the male crickets rubs its two hindlegs together. Which type of energy transformation results in the sound made by crickets?
mechanical energy to chemical energy
mechanical energy to sound energy
thermal energy to chemical energy
sound energy to thermal energy
Which trait does a cactus seedling inherit from its parents?
the number of organisms that consume its fruit
the type of organism that pollinates its flowers
the length of its spines
the amount of water it absorbs
Which structure determines the traits that will be passed to offspring?
spindle fibers
nuclear membrane
centromere
chromosome
The picture shows a kitten, along with its parents.
Why does the kitten appear to be different from either parent?
The kitten is not fully grown and will soon look identical to one of theparents.
The kitten has a disease that makes it look different from its parents.
The kitten did not have the proper nutrition during development.
The kitten gets half its traits from both parents, and this creates variety.
Which of these cell parts store genetic instructions for the entire organism andtransfer those instructions from one generation to the next?
nuclear membranes
DNA molecules
mitochondria
chloroplasts
What kind of energy is stored in food?
electrical
mechanical
chemical
thermal
Which is the most likely result from an overpopulation of barnacles?
increase in sharks
increase in blenny
decrease in hawkfish
decrease in zooplankton
In what form do plants store the energy produced from sunlight?
thermal
radiant
mechanical
chemical
Which is an example of an organism that has been selectively bred for aparticular genetic trait?
cats that eat mice
cows that graze on grass
pigs that form large herds
chickens that lay large eggs
