Chlorophyll is found in plant leaves and absorbs light from the sun to enable plants to
perform photosynthesis. Magnesium is an important component of chlorophyll. The
concentration of magnesium ions is higher in the root-hair cells of plants than in the soil.
Which mechanism of ion uptake would best enable a plant to produce a steady supply
of chlorophyll?
1. Osmosis
2. Diffusion
3. Passive transport
4. Active transport - Correct answer Active transportation
Which best illustrates the result of the process of meiosis?
1. A pea plant has the same flower color as its parent plants.
2. A daughter looks different from both her mother and her father.
3. A cheetah cub has very similar fur to its mother.
4. A Labrador puppy looks exactly like its father. - Correct answer a daughter looks
different from both her mother and her father.
Which level of organization is characterized by a group of cells that work together to
perform a common function?
1. Organ
2. Tissue
3. Organ system
4. Organism - Correct answer tissue
Which best describes a codon?
1. A cell structure that gives the master instructions for an organism
2. A segment of DNA that is the basis of heredity in organisms
3. The sequence of three bases that codes for a specific amino acid
4. The basic unit of structure and function of all living things - Correct answer the
sequence of three bases that codes for a specific amino acid
Which is the final electron acceptor in the electron transport system of cellular
respiration?
, Sheila wants to make a computer model of a land ecosystem. Part of her model
simulates the chemical processes of photosynthesis that involve the creation of sugars.
Which chemical processes are these?
1. The light-dependent reactions
2. The light-independent reactions
3. The daylight reactions
4. The reactions in the mitochondria - Correct answer the light-independent reactions
The equations summarize the process of fertilization. Which equation represents
fertilization?
1. Haploid + diploid = diploid
2. Diploid + haploid = haploid
3. Haploid + haploid = diploid
4. Diploid + diploid = diploid - Correct answer haploid + haploid = diploid
The Venn diagram compares aerobic respiration and anaerobic respiration.
Which statement could be categorized in the overlapping section of the Venn diagram?
Mendel's pea plants had either purple or white flowers. This means that the plants
1. Can self-pollinate.
2. Have two recessive traits.
3. Have two alleles for the gene.
34have two copies of a gene from one parent. - Correct answer have two alleles for the
gene.
Mendel was able to study seven traits in all the pea plants in each generation. Which of
his hypotheses allowed him to analyze each trait separately?
