Science- Goal 7 Adaptations Flashcards
(16 cards)
Endothermic animals
Can maintain their internal temperatures (homeostasis)
Exothermic animals
Rely of their environment for their temperatures
Homeostasis
The ability to maintain internal temperature
An example of exothermic animal
Reptiles and insects
Energy reserves
The storage of energy usually in fat
Camouflage
A shade of color that helps disguise prey from predators
Melanin
A form of natural sunscreen that is coded for by DNA to give people their natural skin tone (Lighter skinned people probably have ancestors from areas with low sun and more pigmented people probably have ancestors who lived there there was lots of sun)
Adapt
To change and develop abilities with special structures that change over time
Waxy coating
An exterior that helps plants in dry areas have conserve water so the plant doesn’t dry out and die,
Spines or Needles
Fleshy plants’ leave in dry areas have a structure that limit gas and moisture exchange to the end of the spine instead of the whole underside of the leaf, it also conserves water, provide shade, collect carbon dioxide, and protect the plant from predators
Dormant
A period of time when living things remain inactive
An example of dormant
Trees go dormant to prepare for harsh winters with limited sunlight
Pollination
The process of which most plants reproduce ( the male sex cells or pollen grow on the stamens above the female stigma which houses the female sex cells or pollen)
What ensures allows seed to disperse and how?
The fruit will allow seeds to disperse so they are spread out across the land by either being carried in the wind or attaching to animals or floating through rivers
What ensure greater variation among plants?
Insects and bugs travel from plant to plant consuming the nectar on the stigma so the pollen rubs onto their body and rubs off onto other plants
What happens when all eggs inside of the flower have been pollinated?
The petals fall off and the plants start producing a fruit around the seed
