Cells & Organelles
This organelle stores hereditary material and controls cell activities.
nucleus
These two systems work together to move oxygen-rich blood from the lungs to the heart.
respiratory and circulatory
If crayfish populations decrease, this population would most likely increase.
snails
The passing of genetic instructions from one generation to the next is called this.
heredity
This product of photosynthesis is needed for cellular respiration
sugar/glucose correct response
will accept oxygen
A group of cells working together forms this.
tissue
A feedback system helps maintain this condition inside the body.
homeostasis
An organism that eats secondary consumers is called this.
tertiary consumer
Asexual reproduction produces offspring that are usually this.
genetically identical to parent
Plants use this process to make food.
photosynthesis
These three structures are found in both plant and animal cells.
cell membrane, nucleus, and mitochondrion
The brain signaling blood vessels to return to normal is an example of this type of system
feedback system
Bees drinking nectar while pollinating flowers is an example of this relationship.
mutualism
A darker desert mouse blending into the sand is an example of a mutation that is likely this.
beneficial
Plants are considered this type of organism in a food web.
producers
This process produces carbon dioxide in cells.
cellular respiration
Hand sanitizer is mainly used to help do this.
limiting disease spread by contact
Clearing forests in the Florida Keys would most likely cause Key deer populations to do this
decrease
For a trait to increase in a population, organisms with that trait must do this.
produce more offspring
A hawk in a food web is usually classified as this type of consumer.
tertiary
This body system protects against viruses and disease
immune system
This system removes wastes from the body
excretory system
In Earth’s carbon cycle, this remains constant
total mass of available carbon
In a cross between Aa and Aa mice, offspring with the genotype aa show this phenotype
recessive phenotype
Energy from the Sun enters ecosystems through these organisms.
