Which one all of the or what

Answer:

Below .

I hope the information give below is helpful .

Explanation:

In question 1 ;

The independent variable is the fertilizer

The dependent variable should be the rate of growth of the plants

The constant doesn't change so other factors that affect plant growth and health, such as soil quality and watering, would need to remain constant.

The controlled variables might be things such as the the quality of soil and the amount of water given to the plants. If these factors were not constant, and certain plants received more water or better soil than others

The experiment in question 1 is a controlled experiment

The part of the garden that didn't receive fertilizer is the control group

According to the question; She didn't hypothesize .

In question 2 '

The independent variable is the floor wax

The dependent variable was protecting the floor tiles against scratches.

It is a controlled experiment but there's no much information to determine if there is any variability and repetition )

The sections that received no wax is the control group

There is no hypothization (if that's a word :) ).The shopping mall didn't hypothesize (maybe that the tough steel would be better )

I'm not sure of any constant needed  when applying floor wax.

Leno4ka [110]

Damage to the nervous system is causing Kai to have pain and numbness.  

<h3><u>Explanation:</u></h3>

Kai injured his knee. We know that the posterior surface of the knee has the quadrangular fossa which is guarded by the tendons of hamstrings anteriorly and by the two heads of gastrognemus muscle below. There are several nerves running down the leg through this region.

Any trauma to this fossa can cause these nerves to get damaged. Thus it can lead to numbness of lower limb. Proper physiotherapy is required to recover as soon as possible. Else that can even lead to paralysis of lower limb.
