Answer:
c. vasoconstriction
Explanation:
Vasoconstriction is a process which involves the narrowing or tightening of blood vessels which becomes smaller when the smooth muscles of these vessels become contracted. The tightening or narrowing of the blood vessels results in an increase in resistance as blood pressure rises, which leads to the restriction of blood flow. Vasoconstriction is the opposite of vasodilation.
Ichthyology is best characterised as Science. None of the other field of studies apply to Ichthyology.
Pseudoscience are beliefs or theories that have been considered scientific. However, they are disapproved scientifically because lack of facts and evidence.
Cryptozoology is study of animals that are rumoured to exist. (Bigfoot, Loch Ness Monster, etc) It is connected with pseudoscience.
Mythology can refer to myths or the study of myths.
As you can see, the study of fish does not apply to any of the area of studies except for Science. Ichthyology applies to Science, because it is a scientific study is different aspects of various species of fish. This includes history, behaviour, and growth.
ν=c/λ
c=300.000.000m/s=300.000.000.000.000.000nm/s
λ=532nm
v=300.000.000.000.000.000/532=5.6*10^14Hz(third option)
Answer:
The brackish water adaptation is clearly necessary because the aquatic snails need to live in an environment in which the river system has a higher quantity of salt than what land snails can take. I can determine that the environmental factors influenced the inherited adaptations because the second population has a higher salt concentration in their habitat compared to the initial population.
