Answer:
The reflex arc follows this sequence of events
1. sensory receptor activation
2. sensory neuron activation
3.information processing
4. motor neuron activation
5. effector response
Explanation:
Reflex arc is the pathway of nerves during a reflex action. An example of a reflex arc is when we accidentally touch a hot object. First, the receptor in the skin detects a stimulus in this case the change in temperature. Second, the sensory neuron transmit the electrical impulses to the Central Nervous System for information processing. Then relay neurons connect sensory neurons to motor neurons. Third, motor neurons sends electrical impulses to an effector wherein the effector produces a response ( muscle contracts to move the hand away from the hot object. This happens in a split of seconds.
the answer is b: blinking when light is flashed in the eyes
Answer:
True.
Explanation:
Lymphatic system is one of the most important system of the body that carries the lymph fluid towards the heart. This system plays an important role in the body immune system.
The pressure in the lymph vessels are very low. The movement of adjacent tissue in the lymph is important to propel it through the lymphatics. The intrinsic or extrinsic compression are important for the lymph flow.
Thus, the correct answer is True.
B. Mesopela: the transmissive barrier through which two cell layers interact in the structure of the coral body
Answer: A) Ocean water evaporates and the warm, moist air rises higher into the atmosphere.
Explanation:
The Equator receives the most direct sunlight on Earth. This makes the water near the Equator, and air above the water, typically warmer than surrounding areas. This warm, moist, less-dense air rises, and then cools as it travels through denser, colder layers. This constant cycle of evaporation and condensation creates an abundance of rain.
So, oceans near the Equator provide ideal conditions for rainfall because ocean water evaporates and the warm, moist air rises higher into the atmosphere.
