Answer:
Commensalism, +/0
Step-by-step explanation:
Commensalism is an association between two organisms in which one benefits and the other is unaffected. In this relationship between the elephants and the cattle egrets, the elephants provide food (insects) for the cattle egrets by exposing them but the elephant itself is neither done any harm or benefit.
+ means positive effect on the organism, - means negative effect, and 0 means no effect. In this relationship,there is a positive effect on the cattle egrets (i.e +), and a neutral effect on the elephants (i.e. 0).
so the denotation will be +/0
X would = 156. 4^2x would = 256 then subtract 100
Answer:
Triangles:
10 m, 21 m, 29 m
10 m, 29 m, 37 m
Not triangles:
10 m, 14 m, 29 m
10 m, 29 m, 40 m
Step-by-step explanation:
For a triangle to exist, the sum of any two sides of a triangle must be greater than that of the third side.
Let us check each of the options.
Option 1: 10 m, 14 m, 29 m
The sum of lengths 10 m and 14 m must be greater than 29 m.
10 + 14 = 24 < 29
So, this is not a triangle.
Option 2: 10 m, 21 m, 29 m
10 + 21 = 31 > 29
21 + 29 = 50 > 10
29 + 10 = 39 > 21
Therefore, it is a triangle.
Option 3: 10 m, 29 m, 37 m
10 + 29 = 39 > 37
29 + 37 = 66 > 10
37 + 10 = 47 > 29
Therefore, it is a triangle.
Option 4: 10 m, 29 m, 40 m
10 + 29 =39 < 40
So, this is not a triangle.
