genetics
how are traits passed from parents to offspring?
Traits are inherited through genes, which happens during reproduction.
What is the smallest unit of living things?
The cell is the smallest unit of living things
What is the outer layer of the cell?
What is the function of the heart?
The heart pumps blood to deliver oxygen and nutrients to cells.
microbiology question - how do plants get their nutrients?
Plants get their nutrients from the soil through their roots, using them for growth and development
what do we use punnet squares for?
we use punnet squares to predict possible combinations of alleles in offspring.
what is the main function of the mitochondria in cells?
Mitochondria are known as the powerhouse of the cell, producing (ATP) through cellular respiration
how does photosynthesis contribute to the production of energy in plant cells?
Photosynthesis converts light energy into chemical energy, producing glucose and oxygen in plant cells, which serves as a source of energy for the cell.
why is the respiratory system essential, what does it do?
The respiratory system allows us to breathe, bringing in oxygen and expelling carbon dioxide, crucial for cellular function.
Genetic question - What is gene mutation?
Gene mutations are changes in the DNA sequence.
how do dominant and recessive genes affect inheritance?
dominant genes mask the effect of reversive genes. to express a recessive trait, an individual must inherit two recessive alleles
what is the role of chlorophyll in plant cells
chlorophyll is responsible for capturing sunlight during photosynthesis, enabling plants to produce their own food.
it also makes the plant green.
What is the primary function of the cell membrane?
The cell membrane regulates the passage of substances in and out of the cell and provides structural support.
Explain the function of the brain in the nervous system
The brain interprets information, controls the body functions, and allows us to think, feel, and respond to the environment.
Cellular biology question - how do lysosomes contribute to cellular maintenance?
Lysosomes are responsible for intracellular digestion, breaking down waste materials and recycling cellular components.
What are the differences between genotype and phenotype
Genotype refers to an organism's genetic makeup, while phenotype is the observable traits.
whats the primary function of ribosomes in a in a bacteria cell
ribosomes in a bacteria cell are responsible for protein synthesis
what is the function of the Golgi app apparatus in a cell?
The Golgi apparatus modifies, sorts, and packages proteins and lipids for transportation within or outside the cell.
How do the kidneys contribute to maintaining the body's internal balance?
kidneys filter blood, removing waste and excess fluids, helping maintain water and electrolyte balance.
What role do muscles play in movement?
Muscles contract and relax to facilitate body movement, from simple actions like blinking to complex activities like running
How does DNA carry genetic information, and what is its structure?
DNA carries genetic information through its double-helix structure, where nucleotide sequences encode instructions for building and maintaining living organisms.
what is the difference between a virus and a bacterium
viruses are smaller than bacteria and require a host cell to replicate, while bacteria are single-celled organisms
explain the importance of mitosis in cellular division
mitosis is crucial for growth, tissue repair, and sexual reproduction, ensuring the accurate distribution of genetic material to daughter cells.
How does the immune system defend the body from infections?
The immune system identifies and fights off harmful pathogens, such as bacteria and viruses, protecting the body from illness.
