Salmon fish hatcheries add a harmless perfume (morpholine) to a stream when they release young fish. When the fish mature, they attract them back to the home stream by using this chemical (in nature the fish smell the unique odors of soil and trees along the home stream). In effect, the hatchery biologist is using
A. the fish's inborn instincts to relocate its own stream.
B. the fish's inborn instincts to relocate its own stream.
C. an experiment based on the ability of fish to learn by trial and error.
D. chemotropisms.
E. Imprinting
Answer:
E. Imprinting
Explanation:
Imprinting is kind of rapid responsive learning occurring at a particular stage in life, whereby the organism establishes a behavioral pattern such as recognition or attraction to it kinship or a substitute.
In the Salmon fish hatcheries(a building where hatching of fish or poultry eggs is artificially controlled for commercial purposes), the addition of a harmless perfume (morpholine) to a stream when they release young fish is a substitute to the Salmon fish kinship. When the fish mature, i.e at a particular stage of their life, they attract them back(a form of attraction to it own kind) to the home stream by using this chemical.
These include the chemical. cellular. tissue organ. organ system and the organism level
Fill in the first blank with lithosphere and the second blank with asthenosphere to make the sentence true.
Answer:
Hey ! I think I can help with this....
a.) Marine life adds carbon dioxide to ocean water during respiration.------Hydrosphere.
b.)Plants on land release oxygen during photosynthesis.----Atmosphere.
c.Bacteria living underground convert ammonia to nitrates.---- Geosphere.
d.)The waste from livestock adds nitrogen to the soil.----Geosphere.
Explanation:
I think geosphere has to do with things concerned with land and atmosphere is concerned with air and hydrosphere is concerned with water.. Thank you for the questions.
