DNA/Mitosis
Where is DNA found?
DNA is found in the nucleus.
What is the organism that pursues another organism called?
Predator
What are the three parts of cell theory?
All living organisms are made of cells. All existing cells are produced living cells. The cell is the most basic unit of life.
What is the definition of Osmosis?
The diffusion of water across a selectively permeable membrane.
What is the claim?
DNA is the genetic carrier and not proteins.
What is the name of the phase in mitosis where chromosomes line up in the middle of the cell?
Metaphase.
What is Commensalism?
Where one organism benefits and the other is not harmed and not helped.
Are unicellular organisms prokaryotic or eukaryotic?
Prokaryotic
How does homeostasis help the body?
Helps maintain a stable internal environment, ensuring proper functioning of organs.
Evidence?
Alfred Hershey and Martha Chase conducted experiments to prove this theory. In their experiments, they showed that when bacteriophages, which are made of DNA and protein, infect bacteria, the DNA enters the cell of the host bacteria, but the protein does not.
During mitosis what is the role of the spindle fibers and which phase do they first attach to the chromosomes?
Separating the chromosomes during mitosis this happens during metaphase.
What are some examples of Parasitism?
Tapeworm and tree fungus.
In a plant cell, is the plasma membrane under or over the cell wall?
In a plant cell, the plasma membrane is under the cell wall.
What is the meaning of diffusion?
Net (overall) movement of particles from an area of High concentration (many particles) to an area of low concentration (fewer particles).
Evidence?
Alfred Hershey and Martha Chase conducted experiments to prove this theory. In their experiments, they showed that when bacteriophages, which are made of DNA and protein, infect bacteria, the DNA enters the cell of the host bacteria, but the protein does not.
How do mutations in genes contribute to developing cancer?
They can disrupt normal control over cell division when these genes are mutated, the G1 checkpoint is usually affected in cancer.
What are the four kinds of symbiotic relationships?
Mutualism, commensalism, competition, and parasitism.
What is the function of the golgi apparatus?
A flattened stack of membranes that modifies, sorts, and packages proteins.
How could temperature affect diffusion?
Increase the rate of diffusion because they provide molecules with more kinetic energy.
Reasoning?
This experiment was enough to prove that DNA was the genetic carrier, and not in fact proteins.
What is the difference between homologous chromosomes and sister chromatids?
Homologous chromosomes are pairs of chromosomes from each parent that have the same genes in the same order, sister chromatids are identical copies of a single chromosome.
What are symbiotic relationships and how is it connected to biodiversity?
Close, long-term interactions between different species where one or both organisms benefit and allow multiple species to coexist and thrive in an ecosystem, leading to a wider variety of life forms.
What is the difference between the smooth and rough endoplasmic reticulum?
The Rough ER has the ribosomes attached to it, meanwhile the Smooth ER does not have ribosomes attached.
What is the difference between diffusion and osmosis?
The key difference between osmosis and diffusion lies in the substance that is moving and the presence of a semipermeable membrane.
Reasoning?
This experiment was enough to prove that DNA was the genetic carrier, and not in fact proteins.
