Are these statements true or false and please explain why If

Are these statements true or false and please explain why:

If variable A has a positive effect on B, the value of B may not have any effect on the value of A

If variable A has a positive effect on B, the value of B could have an effect on the value of A

If J has a positive effect on K, then an increase in the value of k may not have any effect on the value of J

If a blood vessel is considered an organ, and a particular type of connective tissue is vascularized (i.e. it has blood vessels coursing through it), then it is true that, in some cases, a tissue can occupy more space than an organ.

Solution

Answer:

1) If variable A has a positive effect on B, the value of B may not have any effect on the value of A: False

Variable is positive, so, it is dependent, if \"A\" variable is dependent on \"B\" variable, then B variable is directly proportional to A.

2) If variable A has a positive effect on B, the value of B could have an effect on the value of A: True

so, \"A\" variable is dependent on \"B\" variable

3) If J has a positive effect on K, then an increase in the value of k may not have any effect on the value of J : False

In this case, J variable is dependent on variable \"K\", so, with increase in \"J\" variable the \"K\" variable should increase.

4)

If a blood vessel is considered an organ, and a particular type of connective tissue is vascularized (i.e. it has blood vessels coursing through it), then it is true that, in some cases, a tissue can occupy more space than an organ. : True

Connective tissue is the type of tissue present in blood and lymph.It is more abundant in extracellular spaces.
