Cell theory
What is the cell theory
A theory stating that all living things are made up of cells
What is Heredity
The passing on of physical or mental characteristics genetically from one generation to another.
What is homeostasis
The process by which organisms maintain a stable internal environment despite external changes.
In an ecosystem energy flows from..
one living thing to another
Natural selection is
a mechanism of evolution
What are cells
Cells perform all the necessary functions for life, and they are the fundamental building blocks of all living organisms.
What is a dominant trait
A trait that will be expressed if they inherit atleast one dominant allele
3 examples of homeostasis
Blood glucose homeostasis.
Blood oxygen content homeostasis.
Extracellular fluid pH homeostasis.
What is a consumer?
A consumer eats other organisms.
What are the 5 steps
Variation, Inheritance, Selection, Time, and Adaption
All cells come from?
What is a recessive trait
A gene that will be shown if two recessive alleles are shown
Which 7 body systems are involved in homeostasis
What is a producer
Plants and some bacteria utilize sunlight to produce their own food through photosynthesis, a process that converts light energy into chemical energy stored in the form of sugars.
What is the difference between prokaryotes and eukaryotes?
Prokaryotes dont have a nucleus and Eukaryotes have a nucleus
If the genes are Rr, will it be dominant or recessive?
Dominant
Which organs are involved in homeostasis
The liver, the pancreas, the kidneys, and the brain
What do decomposers do
play a crucial role in breaking down dead organisms and recycling nutrients back into the ecosystem, making them available for use by producers.
How does natural selection work with humans?
Differences in climate, nutritional resources or pathogens acted as selective forces, to which human populations had to adapt if they were to survive
All cells contain
DNA
If the genes are rr, will it be dominant or recessive?
Recessive
How to get your body back to homeostasis
Focus on lifestyle changes that support your body's natural balance
Energy Pyramids
They represent the flow of energy through an ecosystem
The 4 principles of natural selection
variation, inheritance, selection, and time
