Hypothesis is a proposed explanation which is made on the basis of given experimental data taken as starting point for further investigation. All hypothesis test are conducted in a same manner fiollowing the four main steps:
1. State the hypothesis
2. Formulate an analysis plan
3. Analyzing the data obtained
4. Final step is to analyze the results
There are three types of variables taken in an experiment:
1. Independent variable: light, temperature, humidity
2. Dependent Variable: these depends upon the other variable. changes in the independent variable may cause the dependent variable to change, for example, growth of plant is a dependent variable which depends upon the amount of light(independent variable), the plant receives
3. Controlled Variable: these variable can be controlled and prevented from being change like ty[pe of plant, type of soil
Answer:
If it's in the table, it's an element! Atoms can join together - they form bonds together - to make MOLECULES. For example, two atoms of hydrogen hook together to form a molecule of hydrogen, H2 for short.

Answer:
Efferent/motor neuron
Explanation:
Efferent/ motor neuron synapse with an effector because efferent neuron is a nerve cell such as motor neuron that transmit electrical impulses o r information from the centre nervous system to the effector which then cause or lead to physiological changes or response to the body . The contain majorly of motor neurons or nerve fiber that send signals from the central nervous system(brain /spinal cord) to the effector neuron for changes that occur physically.
