In a class activity students recorded the results of Left Thumb on top vs Right Thumb on top. The data they collected indicated that 'hand-clasping preference' was
discrete
isolated
unrelated
continuous
The entire collection of the many different types of organisms on the Earth is called
Biological Diversity
A World of Animals
The Living Kingdoms
The Living Ecosystem
A single fetus that grew into a full size human from one sperm cell was a hypothesis held by scientists until the
microscope was improved
first MRI was built
telescope was invented
DNA model was developed
The Science of Genetics is the study of how these types of characteristics are passed on from generation to generation
meiotic
observable
symmetrical
heritable
The most likely alien form of reproduction would be these because they can be dormant for long periods of time and can survive in space
spores
buds
seeds
tubers
Fungi, algae, moulds and non-flowering plants reproduce by producing
spores
buds
seeds
tubers
The distribution of species on the Earth is not even. The area around the equator is where the most diverse plant species exists. This makes for the greatest biological diversity in tropical
tundra
deserts
rainforests
grasslands
Parthenogenesis, meaning virgin birth in Greek, is the term used to describe the process that transforms unfertilized eggs into mature organisms. Bees are a good example, where unfertilized eggs become
male workers
female workers
queen bees
male drones
Plants or animals that can reproduce asexually and sexually include the following
garden worms and slugs
aphids and sponges
prairie cord grass
identical to parent plants every other generation
The system that is used to classify individual organisms is ordered from general classification to very specific identification. The correct order of this classification system is
family, order, phyla, genus, class, kingdom, species
kingdom, phyla, class, order, family, genus, species
phyla, class, order, kingdom, genus, species, family
species, class, family, order, kingdom, genus, phyla
The pistil is made up of the following parts
stamen, stigma, ovary
anther, ovary, stigma
ovary, filament, stigma
stigma, style, ovary
A group of organisms that have the same structure and can reproduce with one another are considered to be
family
genus
order
species
Those characteristics or variations that have a wide range of forms are
discrete
overbearing
obnoxious
continuous
An albino kangaroo is a kangaroo that is pure white. This characteristic is classified as a
continuous variation
discrete variation
non-inherited variation
singular variation
The process that produces two new cells with the same number of chromosomes is called
mitosis
pollination
meiosis
fertilization
Some plants and animals can reproduce asexually and sexually. Alternating between these types of reproduction enables the organism to be
much like their parents
very different from their parents
identical to their parents in all aspects
identical to parent plants every other generation
Variations caused by interactions with the environment are not heritable. Plants that are grown in dim lighting conditions would turn out to be
much like their parents
very different from their parents
identical to their parents in all aspects
similar to parent plants that were grown in dim light
Asexual reproduction is very advantageous because it provides lots of
variation among the species
energy for the species to survive
identical organisms
similar copies of the parent
