Answer:
ase of convenience, since the beneficiary by having a burrow and the shrimp benefits from knowing that there are predators nearby.
Explanation:
This exercise asks to study the dependence between two animals, the shrimp and the puffer fish.
Two types of dependency are defined:
* Complete. What is when one animal lives off the other
* Convenience if one animal does not live on the other
In this case, both the shrimp and the predator do not live on each other, since they feed independently.
So it is a case of convenience, since the beneficiary by having a burrow and the shrimp benefits from knowing that there are predators nearby.
The correct answer is: the balloon benefits by getting a burrow to live in and the shrimp knows when predators are nearby.
I say 1 it seems the most accurate

Answer:
m = 1.45 kg
Explanation:
For this exercise we look for size reduction in height
Reduction = y / y₀
Reduction = 2.15 / 6.75
Reduction = 0.3185
As the statue should not be deformed, all reduction has the same factor.
Let's use the concept of density
ρ = m / V
Initial statue
ρ = m₀ / V₀
It is reduced
V = x y z
V = 0.3185 x₀ 0.3185 y₀ 0.3185 z₀
V = 0.3185³ V₀
Density is
ρ = m / V
ρ = m / 0.3185³ V₀
As the density remains constant we can match them
m₀ / Vo = m / 0.3185³ V₀
m = 0.3185³ m₀
Let's calculate
m = 0.3185³ 45
m = 0.03231 45
m = 1.45 kg
