Answer:
Option A
Explanation:
The displacement in simple term can be defined as the difference between the final and initial position of an object. However, distance is the total length of the movement.
For example - If an object move from point A to B which is a distance of 100 meters, then returns back to point A, and then the total distance traveled is equal to 200 meters while the displacement is zero.
Of all the given options, the distance and displacement is same for option A as the object travels from one to other and stops their only.
Hence, option A is correct
Let's take the example of touching something hot:
there's sensory nerves in all our body, including our hands and fingers. When a finger touches something hot. a nerve impulse will be born due to the stimulus and will be transmitted from the sensory nerves in the finger to the CNS (central nervous system)
The CNS will integrate the information, then transmit nerve impulses through the motor nerves which goes to the muscles of the finger (which are skeletal muscles) to order them to contract, to avoid the contact between the finger and the hot thing. (the same map for the blinking eye)
If I'm not mistaking herbivores are primary consumers
Answer: Cellulose
Explanation:
Starch and cellulose are they two primary polysacharride found in plants.
Starch is the storage polysacharride found in plants in consisting of both linear chain amylose and branch chain amylopectin.
While Cellulose is the structural polysacharride in cell wall of plants. Cellulose consist of a linear chain of thousands of D-glucose units linked together by beta linkages.
