Answer:
Two types of orientation behavior are as follows:
Taxis behavior:
This is a type of orientation behavior that mainly occur in response towards the external stimulus. Taxis may be positive (movement towards the stimulus) or negative ( movement away from the stimulus). Different types of taxis behavior are phototaxis, aerotaxis, chemotaxis and magnetotaxis.
Kinesis:
Kinesis may be defined as a type of orientation behavior that can change the complete movement or orientation of the organism. Kinesis is a random movement and organism can move in either direction. Different type of kinesis are klinokinesis and orthokinesis.
Free energy is a composite function that balances the influence of energy vs. entropy.
Answer:
Halting the use of resources is impractical. Increasing the mining efforts would lead to further depletion of resources. Hence, the correct options are: build dams, use cars that emit fewer harmful gases, and halt the runoff of factory waste into rivers and streams which would positively affect Earth's resources.
Explanation:
The correct answer is (c.) unicellular eukaryotes. Unicellular eukaryotes apply to most protists. Protists are grouping of eukaryotic cells that do not form any natural group. These eukaryotes include the Golgi apparatus and mitochondria, and for plants they include chloroplasts.
Answer:
Explanation:
Electromagnetic waves all travel at the speed of light when in vacuum, and essentially this same speed in normal air. Since wave speed is product of frequency and wavelength, c = f λ and λ = c/f = (3.00 x 108 m/s) / (7.5 x 1014 Hz) = 4.00 x 10-7 m = 400 x 10-9 m = 400 nm.
