Freshwater leeches attach to fish and suck blood from the fish to extend periods of time. This results in sores on the fish that often become infected . This relationship is best described as?
Answers
Answer:
Parasitism.
Explanation:
Parasitism, in biology, is defined as a relationship between different species, formed by a parasite and a host. So, basically the parasite lives in or on the host, causing it harm. Parasites can be describe as predators that eat less than one prey unit, that is, they feed them selves slowly, they don't kill the prey instantly as actual predators do.
So, in this case, we are talking about leeches, which are defined as parasitic worms which lives in freshwater environments. They feed themselves by sucking blood from the host.
Therefore, the relation between these two species is Parasitism.

Answer: The mass of the atom is basically the average atomic mass of all the stable isotopes.
Explanation:
Average atomic mass is defined as the sum of masses of each isotope each multiplied by their natural fractional abundance.
Formula used to calculate average atomic mass follows:
For Example: Taking the element silicon
Three isotopes of Silicon, which are Si-28, Si-29 and Si-30.
Average atomic mass of silicon = 28.086 amu
As, the average atomic mass of silicon is closer to the mass of Si-28 isotope. This means that the relative abundance of this isotope is the highest as compared to the other two isotopes.
Percentage abundance of Si-28 isotope = 92.2%
Percentage abundance of Si-29 isotope = 4.7 %
Percentage abundance of Si-30 isotope = 3.1%
Hence, the mass of the atom is basically the average atomic mass of all the stable isotopes.

CONDUCTION
Explanation:
When a driver touches a cars steering wheel on a hot day heat is transferred to the drivers hand by conduction
The heat is transferred to the driver's hand by conduction because his hand touched the steering wheel (i.e physical contact involved), the heat is transferred through the driver's hand as against radiation that doesn't require any physical contact.
I hope this helps.

Conduction is a heat it transferred to the heat by touching your hand.

In contrast, wind turbines produce no greenhouse gases when generating electricity. We should note that both noise and visual pollution are environmental disadvantages of wind turbines. However, these factors don't have a negative impact on the earth, water table or the quality of the air we breathe.
