Answer:
1. The Diet Pills
2. The Height Of the plants
3. The plant being watered with tap water
4. 8 Trials were included
Explanation:
1. An independent variable is the variable that you change
2. The dependent variable is what you are measuring, in this example the height of the plant
3. This is what you use to base your conclusion on. In this test they are seeing if diet pills affect the height of the plants. So a plant with no diet pill is the control
4. The results were taken at the end of the week for EIGHT weeks. 8 Trials.
The answer for this question is B. Don't require a pre-inspection agreement
Hope I helped please branliest answer if possible
Answer:
The binding of a neurotransmitter on a postsynaptic cell allows potassium ions to diffuse out of the cell. This would result in a NEGATIVE CELL MEMBRANE POTENTIAL which is an HYPERPOLARIZATION event.
Explanation:
The binding of a neurotransmitter to a postsynaptic cell results in a group of channels in the cell membrane called ligand gated channels open or close in response to that binding.
Hyperpolarization occurs when a ligand gated channel opens and allows potassium ion to flow out of the cell.
During hyperpolarization, potential of the cell membrane experience changes which makes it to become more negative.
The flowers will not grow as well because bacteria are needed to fix nitrogen
Numerous plants have symbiotic interactions with bacteria, which provide them with essential nutrients like nitrates. His flowers' growth will be limited and they can even perish if all the bacteria are gone.
<h3>What are Good bacterias ?</h3>
Friendly bacteria or good bacteria can help plants grow by helping the plants to obtain nutrients such as phosphorous and nitrogen, or by defending the plants from other microbes that can make them sick.
- Beneficial good bacteria for plants produce chemicals and hormones that stimulate growth. Beneficial bacteria help prevent infections from pathogens by coating the root surfaces and triggering svstemic disease resistance.
- By this way the use of bacteria killing chemical will all kill good bacteria which helps plant growth.
