Reproduction
What would happen to the rate of reproduction of plants if the water was scarce and the pollinators moved on?
The rate of reproduction of the plants would decrease.
What is an environmental factor? (definition)
Things in the surrounding environment that affect how living things grow and survive
What type of sensory receptor has to do with physical touch, pressure, or vibrations?
Mechanical
What is a phenotype and genotype?
Pheno: physical traits you can see
Geno: genes of the organisms
What is a pollinator?
Helps plants reproduce by moving pollen
True or False: During reproduction (sexual or asexual) the parents transfer genetic information in the form of gene to offspring. The number of chromosomes will be the same as the parent(s) under normal conditions.
True
Name 3 environmental factors.
Water, Temperature, Soil Quality, Bacteria
What type of sensory receptor has to do with taste and smell?
Chemical Receptor
What is the difference between the dominate and recessive alleles? How are they written?
Dominate: will always be expressed in the phenotype if present- Written using capital letters DD or Dd
Recessive: will only be expressed in the phenotype if both genes are recessive: Written using lowercase letters dd
Animal Courtship
List 3 ways plants can increase their changes of reproduction.
Bright Flowers
Sweet Smells
Lots of seeds
Different ways to spread their seeds
What is a genetic factor? (definition)
They are traits passed down from parents to offspring (sexual or asexual)
Name one type of sense that electromagnetic sensory receptors are needs for.
Give an example of a genotype for a heterozygous trait.
Bb
What is an adaptation?
A trait or behavior that helps a living thing survive better in its environment.
Give an example of how males can set themselves apart in order to be chosen by the female as a potential mate.
Dancing- peacock spider
Audio- bird songs
Bright color/display- peacocks
Giving gifts: penguin/otters give rocks. Dung beadles give dung
Name 3 things that can be genetic factors.
Plants- Root Structure, Height, Smell, Fruit Shape
Animals- Gender, Claws, Coloring
What body system is in control of sensory receptors?
Nervous system
Create a Punnett square crossing a homozygous dominate red flower RR and a homozygous recessive white flower rr. How likely is it that the offspring of these two flowers is red?
100%
A chart used to predict the possible traits (genotypes) an offspring might have.
Punnett Square
What is the difference between the asexual and sexual reproduction?
Sexual: two parents contribute genetic material to the offspring making the offspring a genetic mix of the parents.
Name an environmental factor and explain how it could affect an organisms growth.
Water availability: lots of water- positive
lack of water- negative
What interpretates the sensory receptors stimulation and sends the response?
The brain
Create a Punnett square crossing two heterozygous individuals with brown eyes. What is the likelihood that their offspring could have blue eyes?
25%
What is an allelle?
Different version of a gene or trait
