Arte-miy333 [17]

Answer:

In the case of the algae, each individual cell is responsible for absorbing its own water. This makes the algae nonvascular compared to the highly vascular plant species. In this connection, algae also lack several key structures that are normally present in ordinary plants like the leaves, roots and stem.

Describe the Real world examples of newtons third law that were intended in applications of newtons law
AlexFokin [52]

Answer:

  1. The recoil force of a bazooka (reaction) + the accelerating force of a missile
  2. When walking, the foot pushes down and back (action) + the floor pushes up and forward
  3. When a rocket is taking off, the combustion of the fuels (an action) creates a direct and opposite reaction which is the thrust of the rocket upwards.

Explanation:

Newton's third law states that for every action (force) in nature there is an equal and opposite reaction. Simply put, forces act in approximately equal and opposite pairs (Action and Reaction).

This law is one of the reasons why the foundation of a building must be built in such as way that is exerting equal and opposite pressure against the building which it is carrying. When the forces are equal, the balance of forces are said to be in equilibrium.

Cheers!

Tetrodotoxin, also known as "zombie powder" is synthesized by the puffer fish as a defense mechanism. Tetrodotoxin's mechanism o
torisob [31]

Answer:

True

Explanation:

Tetrodotoxin is the molecules that act as a poison to the organism in which they are injected.

The tetrodotoxin proves lethal to the organisms as it kills the organism by interfering with the nervous system. The tetrodotoxin blocks the sodium channels in the neuron as a result of which the sodium is unable to enter the neurons and hence the electrical impulse is not generated.

If the tetrodotoxin blocks the motor neuron transmission by blocking the sodium channels then the signals will not reach the muscle and muscle will not be able to contract.

Thus, true is correct.
