The seismic waves that travel through Earth’s interior are _____ waves.
mrs_skeptik [129]

The seismic waves that travel through Earth’s interior are known as the P waves and the S waves, these seismic waves have differences, first the P waves compress and enlarge the foundations(rocks) as they move through it, while the S waves, shakes the particles of their medium up and down and side-by-side. P waves can travel through solid granite, magma, water or even air, while S waves can only travel through solids, they are unable to travel through fluids. The P waves are the fastest of all known seismic waves, it is the first seismic wave to register on the seismograph, while the S wave is the second one.

Termites share an endosymbiotic relationship with the protozoan that live in their gut. Which statements are true of this relati
Alchen [17]

Answer:

Explanation:

The true statements are:

-The termite benefits from the relationship by receiving food from the protozoan

-The protozoan benefits from the relationship by receiving shelter and food from the termite

The second statement is obvious. The protozoan lives in the termite, eating what the termite eats and enjoying the shelter the termite provides. The first statement is also true, but poorly worded. the termite does not actually receive food from the protozoan. The protozoan only helps to digest the food that the termite has already consumed.

If an enzyme in solution is saturated with substrate, the most effective way to obtain a faster yield of products is to
kompoz [17]

Answer:

a. add more of the enzyme.

Explanation:

Enzymes speed up the rate of reaction by lowering the activation energy for the reaction. They are not used themselves in the reaction. They are specific to substrate molecule. Substrate molecule binds to enzyme's active site and they undergo the reaction to form the product and release back the enzyme.

Rate of reaction depends on both substrate and enzyme concentration. Maximum rate of reaction is reached when all the active sites of enzyme molecules have been occupied by the substrate molecules which means that they are saturated. If more substrate is added at this point it wont have any effect on rate of reaction since there are no free active sites. Hence more enzyme is required to be added so that extra substrate can be utilized and rate of reaction can further be increased.
