Cell structures
What is the difference between Prokaryotic and Eukaryotic cells?
Prokaryotic cells are unicellular organisms, such as bacteria while eukaryotes are mostly multicellular organisms made of eukaryotic cells.
What is the process called when molecules move from an area with a lot of them to an area with fewer?
Diffusion
What can ecology be defined as and what are ecologists and what are they responsible for?
A portion of biology focusing on the study of life and involving the relationships between organisms with one another and their environments. Ecologists are people responsible for the study of ecology
What is the comparison of surface area and volume?
Surface area is the area the exterior surface of a 3D shape, while volume is the area inside of the shape.
What is the claim?
DNA is the primary genetic material (according to the Alfred Hershey and Martha Chase experiment)
What are the three parts of cell theory?
The three main parts of cell theory is that all living things are made of cells, cells are the basic units of life, and that cells come from other cells.
What do we call it when water moves through a membrane that only lets certain things through?
osmosis is movement of water through a selectively permeable membrane,going from where there is more water to when there is less,trying to balance the concentration on both sides.
What can predation be defined as? Provide an example.
The act of pursuing an organism for food (A cat attempting to eat a mouse)
Where can DNA be found in the body?
The DNA is usually found in the nucleus of the cell.
What is the evidence?
“the blender removed much more of the protein parts of the phage than the DNA parts, suggesting that the protein likely remained adhered to the outside of the cell during infection. Since the protein remained outside the cell, it could not be the replicating genetic material”
What are the 3 main parts of a cell along with the functions?
The three main parts of a cell include the cell membrane which acts as a barrier, the nucleus which contains the genetic information, and the cytoplasm which is the fluid that fills the cell.
What type of cell transport doesn’t use energy and lets things move naturally?
passive transport
What is the definition of an ecosystem and what does it comprise of? What are ecologists and what are they responsible for? What can ecology be defined as?
A biological community comprising of interacting organisms as well as their environment(s)/surroundings.People responsible for the study of ecology.A portion of biology focusing on the study of life and involving the relationships between organisms with one another and their environments.
What is the difference between chromosomes and chromatins?
Chromatins are the unorganized form of it, they are all messy and unclear while the chromosomes are the final product resulting in a clean X shape.
What is evidence?
“the blender removed much more of the protein parts of the phage than the DNA parts, suggesting that the protein likely remained adhered to the outside of the cell during infection. Since the protein remained outside the cell, it could not be the replicating genetic material”
How are animal cells different from plant cells?
Animal cells differ from plant cells because they do not include a cell wall for support and chloroplasts for photosynthesis.
What can happen to an animal cell if it’s placed in a solution with more water outside than inside?
Water enters and the cell might swell up and burst.
What is the organism that pursues another organism and what is the organism being pursued?
1. Predator + 2. Prey
What happens during the Interphase, Mitosis in the cell cycle.
During Interphase the cell grows and prepares for division by copying its DNA. The next stage after Interphase is Mitosis, also known as PMAT. During Mitosis DNA condenses into chromosomes, the nuclear membrane breaks down, the sister chromatids line up in the middle of the cell while the chromatids are pulled apart to opposite ends of the cell, and finally the new cell begins to divide.
What is the reasoning?
DNA is the primary genetic material for the reason that through undergoing the blender portion of the Hershey-Chase experiment, while the protein endured various hardships and was considered not to be the replicating genetic material, that left room for the other potential option, DNA.
What is the importance of cell structure?
Cell structure is important because it shows how a cell functions and how it interacts with its surroundings.
What’s the difference between simple diffusion and facilitated diffusion?
Facilitated diffusion uses proteins to help molecules cross the membrane,simple diffusion does not.
What are the names and definitions of the four symbiotic relationships? Provide examples.
Mutualism = A relationship where both organisms benefit equally (A flower getting pollinated while a bee gathers nectar).
Commensalism = A relationship where one organism benefits and the other is neither helped nor harmed (A nearby fish eating the leftover scraps of food of a shark).
Parasitism = A relationship where one organism benefits and the other is harmed (A tick feeding on a cat’s blood while the cat receives a skin irritation).
Competition = Organisms or species competing for limited resources, such as food, water, or shelter (Two or more deer fighting over the same mate).
What is Cytokinesis in the cell cycle?
Cytokinesis is the process of dividing the cell into two daughter cells.
What is the reasoning?
DNA is the primary genetic material for the reason that through undergoing the blender portion of the Hershey-Chase experiment, while the protein endured various hardships and was considered not to be the replicating genetic material, that left room for the other potential option, DNA.
