What is the function of the cell membrane in a cell?

• Stores genetic material

• Produces energy for the cell

• Controls the movement of substances in and out of the cell.

• Regulates cell division

Explain the difference between prokaryotic and eukaryotic cells.

• Eukaryotic cells have a cell wall, which prokaryotic cells do not possess.

• The main difference is the presence of a nucleus and membrane-bound organelles in eukaryotic cells, which are absent in prokaryotic cells.

• Prokaryotic cells are larger in size compared to eukaryotic cells.

• Prokaryotic cells have a nucleus and membrane-bound organelles, while eukaryotic cells lack these structures.

Describe the process of cellular respiration.

• Cellular respiration is the process by which cells break down glucose and other organic molecules to produce ATP, the energy currency of the cell. It involves three main stages: glycolysis, the citric acid cycle, and oxidative phosphorylation.

• Cellular respiration only occurs in plant cells

• Cellular respiration involves photosynthesis to create ATP

• Cellular respiration is the process of breaking down water molecules to produce energy

What is an ecosystem and how do biotic and abiotic factors interact within it?

• Biotic factors are non-living components like sunlight and temperature.

• An ecosystem is a community of inanimate objects interacting with each other.

• Abiotic factors depend on biotic factors for survival.

• An ecosystem is a community of living organisms interacting with each other and their physical environment. Biotic factors are living components such as plants and animals, while abiotic factors are non-living components like sunlight and temperature. Biotic factors depend on abiotic factors for survival, and abiotic factors are influenced by biotic factors.

• Photosynthesis

• Fermentation

• Digestion

• Conservation

• Symbiosis

What is the difference between a predator and a prey in an ecosystem?

• The difference between a predator and a prey in an ecosystem is that predators hunt and feed on other organisms, whereas prey are hunted and serve as food for predators.

• Prey are always carnivorous in an ecosystem

• Predators are smaller than prey in an ecosystem

• Predators and prey have the same role in an ecosystem

How do dominant and recessive genes determine traits in offspring?

• Recessive genes are always expressed over dominant genes in offspring.

• Dominant genes are expressed over recessive genes in offspring. If an offspring inherits a dominant gene from one parent and a recessive gene from the other parent, the dominant gene will determine the trait. Only if both genes inherited are recessive will the recessive trait be expressed.

• If an offspring inherits a dominant gene from one parent and a dominant gene from the other parent, the recessive gene will determine the trait.

• Only if both genes inherited are dominant will the dominant trait be expressed.

What is the purpose of Punnett squares in genetics?

• To predict the possible genotypes and phenotypes of offspring based on the genotypes of the parents.

• To analyze the genetic mutations in parents

• To determine the dominant traits in offspring

• To calculate the probability of genetic disorders
