What do plant cells have that animals cells do not? Animal cells have centrosomes (or a pair of centrioles), and lysosomes, whereas plant cells do not. Plant cells have a cell wall, chloroplasts, plasmodesmata, and plastids used for storage, and a large central vacuole, whereas animal cells do not. How a cell is like a […]
What are examples of spore bearing plants?
What are examples of spore bearing plants? Algae, mosses, and ferns are some examples of plants that produce spores. Although they belong to different clades, they share the same type of reproduction, which is thought to be quite common in the Kingdom Plantae until some groups evolved into seed-bearing plants as another form of reproduction. […]
Why does river discharge increase downstream?
Why does river discharge increase downstream? Changes Downstream As one moves along a stream in the downstream direction: Discharge increases, as noted above, because water is added to the stream from tributary streams and groundwater. As discharge increases, the width, depth, and average velocity of the stream increase. Why are river profiles concave? River profiles […]

What is simple harmonic motion write its any four characteristics?
What is simple harmonic motion write its any four characteristics? (i) In SHM, acceleration of the particle is directly proportional to its displacement, and directed towards the mean position. (ii) It can be represented by a single harmonic function of sine or cosine. (iii) Total energy of the particle executing SHM remains conserved. (iv) It […]
What liquid will water float on?
What liquid will water float on? Lighter liquids (like water or vegetable oil) are less dense than heavier liquids (like honey or corn syrup) so they float on top of the heavier liquids. The same amount of two different liquids you used in the container will have different densities because they have different masses. Does […]

What is an example of physical evidence?
What is an example of physical evidence? Examples of physical evidence include a document, a hair, fibers, fingerprints, soil, and blood. Class Characteristics are properties of physical evidence that can be associated only with a group and never with a single source. What are the classification of physical evidence? According to the general nature of […]
What is the law of conservation of momentum give an example?
What is the law of conservation of momentum give an example? Conservation of Momentum Examples According to the conservation of momentum, the gun receives a backward momentum. The bullet of mass m is fired with forward velocity v. The gun of mass M acquires a backward velocity u. Before firing, the total momentum is zero […]
Where is the waste product of carbon dioxide being created?
Where is the waste product of carbon dioxide being created? During cellular respiration animal cells combine oxygen with food molecules to release energy to live and function. Remember that cellular respiration produces carbon dioxide as a waste product. Animals use energy to grow, reproduce, and to function. They release the carbon dioxide into the air […]
