What are two plant processes? Fundamental processes such as photosynthesis, respiration, plant nutrition, plant hormone functions, tropisms, nastic movements, photoperiodism, photomorphogenesis, circadian rhythms, environmental stress physiology, seed germination, dormancy and stomata function and transpiration, both parts of plant water relations. What occurs only in plants? Photosynthesis occurs only in plants, algae, and some bacteria. How […]

When electric field is applied on the ends of a conductor the free electrons start moving in direction? These free electrons inside the conductor move randomly and frequently collide with heavier atoms and change their direction of motion every time. When a steady electric field is applied to the conductor, the electrons start moving towards […]

What is an example of speed and velocity? Put another way, speed is a scalar value, while velocity is a vector. For example, 50 km/hr (31 mph) describes the speed at which a car is traveling along a road, while 50 km/hr west describes the velocity at which it is traveling. What are 3 examples […]

Is there a ball that can bounce forever? The law of conservation of energy implies that a bouncing ball will bounce forever. Of course, it does not. When you drop it on the floor, it changes some of its energy into other forms, such as heat, each time it hits the floor. What are bouncy […]

Who was one of the first scientist to realize the effects of CO2 in the atmosphere? Svante Arrhenius When was the last time the highest carbon dioxide was recorded in history? The highest recorded measurement in 2018 was 415.70 ppm on May 15, 2019, higher than it has ever been during human history. Yale’s Environment […]

Are entering an expressway and are in the acceleration lane you should speed up to? You should speed up to. You’re entering expressway and you are in the acceleration lane you should speed up that will allow he or she to safely merge into an opening in traffic by the end of the acceleration [ […]

What do you mean by eigen value and eigen function? Such an equation, where the operator, operating on a function, produces a constant times the function, is called an eigenvalue equation. The function is called an eigenfunction, and the resulting numerical value is called the eigenvalue. Eigen here is the German word meaning self or […]

Does cactus need sunlight? Cacti and succulents thrive with good light sources, and it is best to place cacti and succulents in a bright place. A south facing position will provide good sunlight. However, be careful to not put them in direct sunlight because the intense light can make the plants turn a yellow colour. […]

How deep would you need to dive in order to have a pressure of two atmospheres? In order to get to 2 atmospheres worth of air pressure, you would need to get to the point where there’s 29.4 psi (2 times 14.7 psi). To get to 29.4 psi, it turns out that you would need […]

Why can white light be split into Colours? White light is a mixture of many different colours, each with a different frequency . Light is refracted when it enters the prism, and each colour is refracted by a different amount. This means that the light leaving the prism is spread out into its different colours, […]
