QuestionAnswer
Many unicellular organisms reproduce by the process of fission
During which phase are the duplicated chromosomes visible and the nuclear membranes begin to dissolve? The centrioles will also begin to move to the opposite ends of the cell. Prophase
What are made of segments called genes and contain the genetic information necessary for cell reproduction? Chromosomes
Both involve at least one parent Both produce offspring Offspring are of the same species asexual reproduction
embryo spends a long time in uterus; fetus fed by placenta; nutrients derived from mother's blood through close proximity of fetal and maternal blood vessels in placenta acental Mammals
egg-laying mammals; have mammary glands but no nipples; produce milk in skin depression; duck-billed platypus/echidna Monotremes
single organism containing both testes and ovaries; earthworms, tapeworms, snails Hermaphrodites
egg laying Oviparity
via mitosis; increases population; creates clones Asexual Reproduction
some fishes and amphibians, all land animals; prevents dessication of gametes Internal Fertilization
diploid; produced by fertilized eggs Female Honeybee workers
ten chromosome mammal; combination of XY and WZ system Duck-billed Platypus
mammals; female homozygous for sex chromosome (XX); males heterozygous (XY) XY sex determinizatio
haploid; produced by unfertilized eggs Male Honeybee drones
amniotic egg; immerses embryo Amnion membrane
amniotic egg; encloses yolk; nourishes embryo Yolk sac
egg retained and hatched inside mother; live-bearing of very small young; no extra nourishment from mother once egg is formed Ovoviviparity
structured to avoid dessication; surrounded by shell Amniotic Egg
live-bearing; mother's blood nourishes developing embryo Viviparity
pouched animals; young born relatively undeveloped, complete development in pouch; drink milk in pouch; kangaroos/opossums Marsupials
amniotic egg; controls permeability Chorion membrane
amniotic egg; for wastes; grows out of hindgut Allantois membrane

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
