Answer:
The correct answer will be-dependent variable.
Explanation:
The scientific experiments are performed to study the variables which are of two types: independent variables and dependent variables.
The independent variables are the variables which can be controlled and changed and the variable to be studied is known as the dependent variable.
In the given experiment to study the prediction of Charles Darwin the experimental groups were divided to study the number of seeds produced. Nets were used to prevent the pollination by long mouth tube pollinators and allowed short mouth tube pollinators.
Since the number of seeds produced was studied will be known as the dependent variable and hence is the correct answer.
Answer:
b. the positive feedback's effector responses are in the same direction as the initiating stimulus rather than opposite of it
Explanation:
Both positive and negative feedback have the same components:
1. Stimuli - external or internal
2. Sensors - detect the stimuli
3. Control center - processes the information (CNS)
4. Effectors - activated by control center
Negative feedback loops act to oppose the stimulus.
Unlike negative feedback loops, positive feedback loops amplify the starting signal.

angle of incoming sunlight
Explanation:
The single feature that primarily determines the variation in climate in different parts of the world is the angle of incoming sunlight.
- Climate is simply an extended study of weather over a long period of time.
- The elements of weather like temperature, pressure, rainfall all conditions climate.
- The angle of incoming sunlight is by far the most important factor that determines climatic patterns on the earth.
- Around the equator, the sun is overhead and these regions are usually hot driving a wide range of weather phenomenon.
- The polar and temperate regions receive diffused sunlight because the sun is at an angle there.
