Reproductive Adapt

quiz on reproductive adaptations and sexual vs asexual reproduction

QuestionAnswer
Natural selection Individuals with favorable variations survive and reproduce
genetic drift occurs in small populations, when genes are lost for the population
Classifications system continually changing because of new advances in technology which better allow us to study organisms
homeostasis biological balance, example being able to maintain body temperature by sweating when we exercise
anmiotic egg an egg that is protected by several layers of membranes, allowed organisms to move to land for fertilization and not have to rely on water
gamete sex cell, example egg or sperm
a freshwater plant placed in salt water will shrink because water will move out of the cells
mutations passed to offspring must occur in a gamete or sex cell, can not be passed on to offspring, if occur in a body cell ex skin cancer is not hereditary but an mutation in a gamete cell is.
active transport ATP or energy is required to move substances into or out of the cell.
mitosis when a cell divides and produces another cell identical to the parent cell. Can be a form of asexual reproduction in some single cell organisms.
Sexual reproduction produces offspring with traits from both parents, allows for an independent assortment of parent chromosomes. Produces the most variation
asexual reproduction produces offspring with traits identical to the parent
Meiosis allows for a gamete to have half the number of chromosomes as the parent cell.
seed embryo and its food supply, can lay dormant for years until it is put in an environment that is suitable for it to grow.
contractile vacuole organelle in single cell organism that allow it to move water out of its body so it doesn't explode
