Which explanation most likely accounts for the increase in the number of male butterflies in the five years after the initial parasite problem?

Male butterflies in the population that survived had a gene that made them resistant to the parasite, and they passed the gene on to their offspring.

Female butterflies in the population that survived were able to prey on the parasites living in the males' egg cells.

Female butterflies in the population that survived had a genetic adaptation that allowed them to transform into male butterflies.

Female butterflies in the population that survived were able to protect the male eggs from the parasite and provide extra care for the male offspring.

Which statement explains the increase in gill surface area seen in some of Lake Victoria's cichlids?

Increased gill surface area has allowed the cichlids to better absorb the limited oxygen in the water.

Increased gill surface area has allowed the cichlids to change their diet and avoid competing with the Nile perch.

Increased gill surface area has allowed the cichlids to be camouflaged and avoid being eaten by the Nile perch.

Increased gill surface area has allowed the cichlids to leave Lake Victoria and establish populations in nearby bodies of water.

All cells arise from pre-existing cells.

All cells are capable of photosynthesis.

All cells can develop into any other type of cell.

Which of the following organisms can produce offspring that are genetically identical to the parent organism?

Amoebas, yeasts, hydras, and ferns only

Cats, hydras, frogs, and ferns only

Certain species of whiptail lizards have only female individuals and no males. These lizards reproduce asexually. What is one disadvantage of asexual reproduction for these lizards?

B) All the members of a population are genetically very similar and less able to survive environmental changes.

A) A new population can be established by a single individual in a relatively short period of time.

C) They are smaller than lizards that reproduce sexually.

D) They are more likely to develop a variety of tail lengths.

CHOOSE THREE statements that describe a characteristic of asexual reproduction in strawberry plants.

The offspring will be identical to one another

The parent plant produces offspring by using runners.

The offspring can have two parents

50% of the DNA comes from the parent plant.

What role do genes play in determining the traits found in the strawberry daughter plants?

Genes are found in the chromosomes which are contained in the nucleus of a plant cell.

Genes control which traits are inherited by the strawberry daughter plants

Genes control which traits are not inherited by the strawberry daughter plants.

Genes are found in cytoplasm which are contained in the nucleus of a plant cell.

How does energy change FORM during the process of photosynthesis so that the daughter plant can grow?

The plant absorbs light energy from the sun, that energy is converted into chemical energy , then it is stored within the plant as sugar.

The plant absorbs the chemical energy from the sun and converts it to sugar .

The plant absorbs the light energy and stores it as chemical energy.

The sun converts the plant to sugar.
