Science - Chapter 2

the passing of traits from one generation to the next heredity
traits that offspring receive from their parents inherited traits
a way of acting or behaving with which an animal is born instinct
a behavior that devolps during an animal's lifetime learned behavior
when an animal is born/hatched, they learn to recognize and follow their mother imprinting
Mendel discovered that each inherited trait, one from each part, is controlled by factors
today scientists refer to Mendel's factors as what genes
genes are found in the nucleus of the cell and stored here chromosomes
a trait that masks another trait dominant trait
a trait that is masked recessive trait
in pea plants, purple flowers are a dominant trait and white flowers are a recessive trait. the white trait is represented by p and the purple trait is by ? PP
a chart used to trace the history of traits in a family pedigree
on a pedigree chart, horizontal lines connect parents and vertical lines connect parents to this offspring
males represented by squares, and what is represented by circles females
dimples are a dominant trait, represented by the letter D. a child who is a carrier of the recessive trait is represented by Dd
contains the chemical instructions for an inherited trait gene
individual who has inherited a gene for a trait, but does not show the trait physically carrier
the development of a seed into a new plant germination
a stage of metamorphosis where the organism is similar to an adult for but is smaller nymph
the four stages of complete metamorphosis egg, larva, pupa, adult
a series of distinct growth stages that are different from one another metamorphosis
the transfer of a pollen grain to the egg-producing part of a plant pollination
the process in which sperm and egg cells come together outside of the females body external fertilization
a thin plant stem that puts down roots and gives rise to new plants runner
a developing organism that results from fertilization embryo
the joining of a sperm cell with an egg cell to make one new cell, a fertilized egg fertilization
a butterfly hatches from an egg as a larva. the larva feeds and grows until it forms a pupa
inside the pupa, a larva's body changes completely into ? an adult butterfly
grasshoppers emerge from their eggs as this, that is similar to the adult BUT lack wing and reproductive organs nymph
sperm and egg celss must stay protected and ??? for fertilization to occur wet
fish and amphibians release their sex cells into the surrounding water, where this takes place external fertilization
fish and amphibians must realease large amounts of sex cells because the chances of this in open water are low fertilization
the joining of sperm and egg cells inside the female's body internal fertilization
animals that use internal ferilization reptiles, birds, mammals
increases the chances that eggs will be fertilized and offspring will survive internal fertilization
animals that lay their eggs in open water fish and amphibians
this provides food for a developing embryo egg's yolk
reptiles and birds have eggs filled with ??? and surrounded by ??? so their eggs can laid on land jelly-like liquid and shell
their embryos develop inside the mother most mammals
the joining of a sperm cell and an egg cell into a single unit fertilization
What is an organism that can reproduce through budding? sponges
What is one advantage of sexual reproduction? the offspring share traits of both parents
cells that can develop into new individuals without ferilization spores
the female part of a flower pistal
why do plants produce nectar? to attract pollinators
which of the following is part of a seed? embryo plant, pistil, seed membrane, anther seed membrane
how are nymphs different from adult insects they have no wings or sex organs
which kind of animals release their sex cells into water fish and amphibians
which of the following animals produces a hard-shelled egg the matures outside the mother? salmon, bullfrog, robin, lion robin
the purpose of an egg yolk is to feed the growing embryo
Which of the following is an example of a learned behavior? an oriole builds a hanging nest; a dog comes when it is called; a baby takes its first breath; a rabbit hides from danger a dog comes when it is called
imprinting is an example of a... learned behavior
Gregor Mendel discovered...organisms, have dominant and recessive traits; organisms can learn behaviors; genes are parts of chromosomes; genes are chemical instructions for cells that organisms have dominant and recessive traits
any characteristic of a living thing trait
the production of a new organism from one parent asexual reproduction
how bacteria reproduce splitting
a bud growing from a fungus to become a new individual budding
a new plant growing from a leaf vegetative propagation
a new organism from two parents sexual reproduction
a cone-bearing tree conifer
the tiny offspring inside a see that can grow into a new plant embryo
development of a seed into a new plant germination
contain a flowering plant's sperm cells pollen
seeds with two cotyledons dicot
seeds with one cotyledon monocot
the tough, outer covering on a seed seed coat
