Answer:
b) The roots grow towards the force of gravity and the stem goes away
Explanation:
The parts of a plant can be divided into shoot and roots. The root of the plant is the part that grows below the ground surface in order to anchor the plant. When a seed germinates, the root part of that seed grows towards GRAVITY i.e exhibits geotropism while the shoot part grows away from gravity i.e. upwards.
Hence, if a seed is planted upside down, it will still grow into an erect mature plant because THE ROOT WILL ALWAYS GROW DOWNWARDS IN RESPONSE TO GRAVITY (positive geotropism) while the stem grows upward away from gravity (negative geotropism)
Answer:the sensor or receptor
Explanation: homeostasis is the process of the body to maintain a constant internal condition , regardless of changes in it's external environment.
Homeostatic usually involves a sensor/receptors on which detects changes or stimuli,A control center which process the stimuli and triggers the effector and An effector which changes the body according to the message recieved from the control center.
In an air conditioner,the thermometer is the sensor,which detects a change in the temperature of the room.this allows the air conditioner to control the temperature and keep it constant, regardless of the temperature outside.
