Answer:

b. The pairs in which neither individual is given extra juvenile hormone is the control

Explanation:

This is an experiment in which the researcher wants to establish a relation between the aggresion in wasp with the juvenile hormone, but to know which are really the effects you need something to compare with, that is called the control group, that is usually in the normal conditions, in this case it corresponds to the pairs in which they don't give the extra juvenile hormone, so the researcher can compare the difference between this pair with the pair in which one of the individuals has extra juvenile hormone.

Solve the simultaneous equation <br>y+x=4<br>2y-x=5​
beks73 [17]

Answer:

<h2>Value of X = 1</h2>

<h2>Value of y = 3</h2>

Solution,

Using substitution method,

y + x = 4

Move 'x' to the left hand side and change its sign:

y = 4 - x --------> equation (i)

Now,

2y - X = 5

putting the value of y from equation (i)

2( 4 - x ) - X = 5

8 - 2x - x = 5

8 - 3x = 5

- 3x = 5 - 8

- 3x = - 3

The difference sign (-) will be cancelled in both sides

3x = 3

3x/3 = 3/3

X = 1

Value of X is 1

Now, replacing the value of X in equation (i)

y = 4 - x

= 4 - 1

= 3

Value of y is 3

Hope this helps...

Good luck on your assignment...
