Evolution
This type of evolution happens when 2 independent organisms both evolve similar traits, structures, or behaviors independent of the other organism.
What is convergent evolution?
The zygote grows into the sporophyte, which then produces spores by meiosis is a description of this reproductive strategy in plants.
What is alteration of generations?
This category of animals possess hair, are endothermic, and nurse their young.
What are mammals?
This once kingdom of eukaryotes is no longer a taxonomic group because it contains various members some of which are more closely related to plants, animals, or fungi than to other members of this same group.
What are protists?
The maintenance of a relatively constant and optimal internal environment which is often maintained through negative feedback systems is known as this.
What is homeostasis?
When allele frequencies change in a random way in a group of individuals with a small population, this is the most likely cause.
What is genetic drift?
This structure allowed plant embryos to survive during poor environmental conditions and therefore improved plants' adaptation to land.
What are seeds?
This animal phyla has the greatest species diversity.
What is arthropoda?
This type of bacteria has a cell wall consisting of a thin layer of peptidoglycan and an outer membrane.
What are gram-negative bacteria?
This cavity aids in circulation and digestion.
What is the gastrovascular cavity?
According to this theory mitochondria originated from an engulfed, previously free-living prokaryote.
What is endosymbiotic theory?
Liverworts and mosses require a wet environment because they lack this type of tissue.
What is vascular tissue?
This group of vertebrates was the first to have an amniotic egg.
What are reptiles?
In this kingdom the processes of plasmogamy and karyogamy are separated by a heterokaryotic stage.
What are fungi?
This type of feedback causes a change in a variable to amplify rather than reverse the change.
What is positive feedback?
This form of speciation occurs when physical barriers (mountains, being on different islands, etc.) separate organisms and therefore limit interbreeding.
What is allopatric speciation?
Plants release of this gas lead to the rusting of iron in ocean water and terrestrial rocks.
What is oxygen?
What are mantle, visceral mass, and foot?
This structure of a primary mycelium secretes digestive enzymes to break down organic materials for absorption.
What are hyphae?
This type of reproduction is better suited for environments with changing conditions.
What is sexual reproduction?
When an organism leaves more viable offspring than others of its species, we say that it has greater this.
What is biological fitness?
This angiosperm structure contains 3 sets of chromosomes.
What is the endosperm?
A predator eating most of the prey and leaving no prey for other predators could lead to this, also known as Gause's law.
What is competitive exclusion?
This supergroup includes red algae.
What is archaeplastida?
On a windy day an animal might get chilled more easily because this rate has increased between the animal and its environment.
What is rate of heat exchange?
