Front

What is the function of the plasma membrane in cellular homeostasis?

Back

The plasma membrane regulates the movement of substances in and out of the cell, maintaining a stable internal environment.

Front

What are the products of photosynthesis?

Back

Oxygen and glucose are produced during photosynthesis.

Front

What are the two main types of cells?

Back

Prokaryotic cells (without a nucleus) and eukaryotic cells (with a nucleus).

Front

What is the genotype for wire hair in dogs?

Back

The genotype for wire hair is represented as 'H' (dominant allele).

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

How many homozygous recessive offspring are expected from a Punnett square of SsRr?

Back

1 out of 16 offspring is expected to be homozygous recessive for both traits (ssrr).

Front

What is a Punnett square used for?

Back

A Punnett square is used to predict the genotypes of offspring from a genetic cross.

Front

Define allele.

Back

An allele is a variant form of a gene that can produce different traits.

Front

What is the difference between dominant and recessive alleles?

Back

A dominant allele masks the effect of a recessive allele in a heterozygous genotype.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy, carbon dioxide, and water.
