B and D. The xylem and the phloem make up the vascular tissue of plants and transport water, sugar, and other important substances around a plant.
The cells that die are emptied, leaving hollow cell walls with their ends open, thus forming pipe-like structures
Hope this helps
Answer:
The answer is: Classical Conditioning.
Explanation:
- According to the theory of Classical Conditioning, an Unconditional Stimulus can be defined as such a stimulus that is capable of triggering a response spontaneously and naturally without the requirement of a previous learning or knowledge about the stimulus.
- A Neutral stimulus can be defined as such a stimulus which is responsible for drawing or focusing the attention of a person to a particular event.
- A Conditional Stimulus can be defined as such a stimulus which is generated due to the repeated integration of an Unconditional stimulus to a Neutral stimulus. The repeated integration eventually results in the generation of a conditioned response.
- In the given example, a bit of black pepper blown into the eyes for the first time is an example of unconditional stimulus. This stimulus initiates a spontaneous or unconditional response, that is, blinking of eyes.
- But, when this unconditional stimulus gets integrated to the neutral stimulus (irritation in the eyes draws the attention of the person) repeatedly, it can result in the generation of a Conditioned Response (blinking of eyes whenever any foreign object gets into it).
I still didn't learn that but a guess would be Climate is a long-term model of weather in specific location or place. Thus, aspects of climate that are most important to forest ecosystem is the temperature and precipitation. Because. <span>1. Temperature determines the adaptable and environmental influences such as the sunlight, the biotic community and especially the photosynthetic mechanisms of plants which is responsible for making its own food.</span> <span>2. <span> Precipitation. Water is vital in many aspects of plants since it is one of the materials needed for plant’s food-making process.<span>
