What is natural selection?

Back

Natural selection is the process by which organisms better adapted to their environment tend to survive and produce more offspring.

How do enlarged pectoral fins benefit blue flying fish?

Back

Enlarged pectoral fins allow blue flying fish to glide above the ocean surface, helping them escape predators and increasing their fitness.

Front

What is the role of mitochondria in cellular respiration?

Back

Mitochondria use oxygen to produce ATP, which is the energy currency of the cell.

Front

What is the process of transcription in gene expression?

Back

Transcription is the process by which specific DNA segments are copied into mRNA, which is then translated into proteins.

Front

What is the expected percentage of homozygous smooth-haired offspring from a cross of two heterozygous dogs (Hh x Hh)?

Back

25% of the offspring are expected to be homozygous for smooth hair (hh).

Front

What is the difference between mitosis and meiosis?

Back

Mitosis produces two identical daughter cells, while meiosis produces four genetically diverse haploid gametes.

Front

What is ATP and why is it important?

Back

ATP (adenosine triphosphate) is the primary energy carrier in cells, providing energy for various cellular processes.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

Front

What are alleles?

Back

Alleles are different forms of a gene that determine specific traits, such as hair type in dogs.

Front

What is the significance of gene transcription?

Back

Gene transcription is crucial for the expression of genes, allowing cells to produce the proteins necessary for their functions.
