To answer these questions, we can eliminate the incorrect options and analyze the remaining options.
1) How do hollow bones improve the survival of birds?
- They help them obtain more oxygen.
- They help them obtain food.
- They help them detect predators.
- They help them to react to stimuli.
In this case, the correct answer is not provided in the options. Hollow bones in birds actually improve their survival by reducing their weight, making it easier for them to fly. The correct answer is not listed.
2) What stimulus could trigger a fight or flight response?
- Geomagnetic information
- Temperature change
- Seasonal change
- Sensory information
The correct answer in this case is sensory information. The fight or flight response is triggered by the perception of a threat or danger, which is sensed through the sensory system.
3) What stimulus causes plant roots to grow downward?
- Light
- Pollution
- Gravity
- Temperature
The correct answer in this case is gravity. Plant roots exhibit positive gravitropism, meaning they grow in the direction of gravity. This helps them anchor the plant and allows the roots to absorb water and nutrients from the soil.
4) Which of the following is an internal stimulus?
- Water in a cell
- Amount of daylight
- Habitat temperature
- Habitat pollution
The correct answer in this case is water in a cell. Internal stimuli are those that originate within the organism. The presence or absence of water in a cell is an example of an internal stimulus.
5) What is the process of maintaining a stable internal environment in an organism?
- Stimulus
- Phototropism
- Homeostasis
- Response
The correct answer in this case is homeostasis. Homeostasis is the process by which organisms maintain a stable internal environment despite external changes. It involves regulating variables such as temperature, pH, and nutrient levels to ensure optimal functioning of the organism.
