Q3 Assessment Prep - RMSA 23-24

Which statement best describes the nature of mutations in genetic material?

• Mutations always result in visible changes to the organism's phenotype.

• Mutations are exclusively detrimental, leading to diseases and disorders.

• Mutations can be beneficial, harmful, or neutral, depending on their impact on the organism's genes.

• All mutations are corrected by cellular mechanisms, thus they have no long-term effect on organisms.

How do the genetic variations between species such as wolves and butterflies arise?

• Through environmental influences only

• Gene mutations, natural selection, and recombination of genes

• Only through gene mutations

• Gene mutations and recombination of genes

What processes are essential for the changes of new heritable traits in a population over time?

• Natural selection and genetic drift

• Gene mutations and genetic drift

• Natural selection, gene mutations, and genetic drift

• Gene mutations, natural selection, and recombination of genes

In a shared habitat, rabbits and deer both rely on the same types of plants for food. Considering this, which statement accurately reflects their relationship?

• Rabbits compete with other rabbits, deer compete with other deer, but rabbits and deer do not compete with each other for the plants.

• Rabbits do not compete with other rabbits, deer do not compete with other deer, and rabbits and deer do not compete with each other for the plants.

• Rabbits compete with other rabbits, deer compete with other deer, and rabbits and deer compete with each other for the plants.

• Rabbits do not compete with other rabbits, deer do not compete with other deer, but rabbits and deer compete with each other for the plants.

Which of the following statements about competition between animals is TRUE?

• Animals compete for food when it is limited, but they do not compete for water when it is limited.

• Animals compete for food and water when they are limited, but they do not compete for shelter when it is limited.

• Animals compete for food, water, and shelter when they are limited.

• Animals do not compete for any resources, even when they are limited.

How does competition for scarce resources affect the behavior of animals in the same habitat?

• It leads to an increase in cooperation among different species.

• It causes no significant change in their behavior.

• It results in more aggressive behaviors to secure resources.

• It encourages migration to areas with abundant resources.

What determines the hair color of a newborn, making it often similar to the hair color of their parents?

• Color pigments directly transferred from parents to children.

• Specific cells that are responsible for hair color are inherited from parents.

• Genetic information on DNA that influences hair color is inherited from parents.

• Nothing related to hair color is genetically passed from parents to children.

How does nest guarding behavior benefit the offspring of the a bird that defends its nest?

• It increases the chances of offspring survival by protecting them from predators.

• It allows the offspring to grow larger by providing more food.

• It enables the offspring to develop brighter skin colors.

• It encourages the offspring to leave the nest earlier.

Which of the following observations best supports the claim that guarding the nest increases the chances that the female's eggs will hatch?

• Fewer eggs are eaten when females keep egg-eating snakes away from the eggs in their nests.

• Some females stay at their nest with their eggs for several days after laying them.

• Many egg-eating snakes attack and try to eat the eggs in female skinks' nests.

• Egg-eating snakes move away from the eggs when the females stay at their nest.

Match the term "alleles" with the correct definition.

• Gene that is always expressed

• Different forms of genes for a single trait

• Genotypes made of two different alleles

• Gene that can only be expressed in the homozygous state
