What is the difference between plant tissue and animal tissue |
|
Answer» (Note : First sentence of each pount is of plant tissue and second sentence is of animal tissue )1. In plants , dead supportive tissues are more abundant as compared to living tissues.In multicellular animals living tissues are more common as compared to dead tissues.2. They require less maintenance energy .They require more maintenance energy.3. Tissues organisation is meant for stationary habit of plants.Tissues organisation is targeted towards high mobility of animals.4. Due to activity of meristematic tissues plants continue to grow throughout life.Animals do not show growth after reaching maturitybut repartive growth is present. Plant tissue have no muscular organs and animal tissye hack |

Example of newtons second and third law of motion |
| Answer» Example second law of motion: when acceleration is applied on a moving vehicle, the momentum of the vehicle increases and the increase is in the direction of motion because the force is being applied in the direction of motion. On the other hand, when brake is applied on the moving vehicle, the momentum of the vehicle decreases and the decrease is in the opposite direction of motion because the force is being applied in the opposite direction of motion.Example of third law of motion are:\tIf you throw a heavy ball or block away from your body, the force exerted will push back on you, possibly pushing you backward onto the ground.\tA book lying on a table exerts a force on the table which is equal to the weight of the book (action force). The table supports the book, by exerting an equal force on the book (reaction). As the system is at rest, net force on it is zero. Therefore, forces of action and reaction must be equal and opposite.\tWhen a gun is fired, the bullet moves forward (action). The gun recoils backwards (reaction). | |

What\'s the benefit of lysosome in our body. |
|
Answer» If any foriegn material or any other thing tries to enter in the cell and succeed. Lysosomes releases powerful dygestive enzymes capable to destroy that material.
