Macromolecules
This is a example of protein and an enzyme, not a carbohydrate.
What is ase
What causes ice to expand and float when water freezes?
Water is less dense than ice, which is because of water molecule structure
Why causes cells to shrink?
Water leaving the cell with a high concentration inside than outside, making it hypertonic.
Asexual Reproduction: Mitosis or Meiosis?
Mitosis
What is diffusion
The movement of molecules in a fluid that goes from a higher concentration to a lower concentration
What's the difference between an carbohydrate and a lipid? How are they similar?
Lipids are short term energy, carbs provide quick energy. Both are composed of C H O.
What's the difference between adhesion and cohesion?
Cohesion is water molecules sticking to other water molecules. Adhesion is water sticking to other substances.
This organelle has layered stacks with closed membrane spaces that contains enzymes that delivers proteins
What is the Golgi apparatus
When does crossing over occur? Mitosis or Meiosis? Why?
Meiosis. Because it exchanges DNA segments between homologous chromosomes, thus creating greater variations.
This solution has fewer solutes and more water go into it, causing it to explode.
What is a hypotonic solution
We store excess carbohydrates as this.
What is glycogen
An attraction between slightly positive and slightly negative atom, often oxygen or nitrogen.
What is a hydrogen bond
This plant cell organelle is where the process of photosynthesis occurs.
What is a chloroplast
This process divides the cell cytoplasm, resulting in identical daughter cells linked to original cell.
What is Cytokinesis
The diffusion of molecules across a membrane through transport proteins, making it easier for molecules to enter or exit.
What is facilitated diffusion
Name the four monomers of carbon-based molecules
Carbs- simple sugars (monosaccharides) Lipids- fatty acids Protein- amino acids Nucleic Acids- nucleotides (DNA and RNA)
Hydrogen bonds give water the ability to resist increased temperatures to absorb increased energy. This also uses chemical energy in cell temperatures.
What is High Specific Heat
The three parts of the cell theory
Cells are the basic unit of life, all living things are made of cells, all cells come from pre-existing cells
The fusion of an egg and a sperm cell
What is fertilization
What's the difference between passive and active transport?
Active transport has cells using energy to move substances against a concentration gradient, but passive transport cells don't require energy
What is the difference between ADP and ATP?
ATP transfers energy to cell processes. ADP is a lower-energy molecule that can be converted into ATP.
What is the difference between a solute and a solution
Solutes are the substances that dissolve in a solution, which is a homozygous mixture of the two solutes
Cell molecules are composed of phospholipid layers. These are the three parts of it
What is a charged phosphate group, glycerol, and fatty acid chains
What happens before the meiosis process begins?
DNA is already copied
The process of molecules moving across a semipermeable membrane from high to low concentration areas
What is osmosis
