Infestations of Sarcoptes Scabiei or itch mite, cause an disease called Scabies. Scabies is a unpleasant, infectious, and nonlethal itching disorder characterized by the mites burrowing into the skin.

Answer:
Mutualism
Explanation:
Mutualism is a feeding relationship between two different types of organisms both of which benefit from the association. The fungus derives ions from the water run-off and shares with the alga. The alga provides fungus with sugars which it produces through photosynthesis.
Answer:
18 litres
Explanation:
Using Boyle's law equation as follows:
P1V1 = P2V2
Where;
P1 = initial pressure (atm)
P2 = final pressure (atm)
V1 = initial volume (litres)
V2 = final volume (litres)
According to the information in this question, An inflated basketball hold 6 liters (V1) of air at 3 atm (P1). The volume of air (V2) at 1 atm (P2) that went into the ball can be calculated thus:
Using P1V1 = P2V2
3 × 6 = 1 × V2
18 = V2
V2 = 18 litres.
Answer:
The rock will be old between 360 and 290 million years
Explanation:
If we have fossils from both nautilus and goniatite in the same rock layers, then we can look at the periods in which these two animals lived as a clue about the age of the rocks, thus the animals themselves as well. The nautilus occurs in the fossil records around 410 million years ago, but it is not extinct, in fact it still exists and it is one of the oldest species on the planet. The goniatite has had different story, as it existed for around 70 million years, between 360 and 290 million years ago. We can see from this information that these two organisms coexisted throughout the whole existence of the goniatite, thus the rocks can have an age of anywhere from 360 to 290 million years.
