The image shows rock strata from three different regions on Earth. Identify all the layers that contain an index fossil
FrozenT [24]

The correct answer is: Layer 1, layer 2, and layer 4 in all three regions.

The index fossils are fossils that are commonly used for identifying a geological period of time, and these fossils are also very wide spread, as well as having a rapid evolutionary trends.

By this picture, we can easily see that even though we have rock strata from different regions, the same layers contain the same fossil, and it is a fossil that also is rapidly evolving so has a minor change in each layer.

Can same enzyme have different kinetics for different substrates? What is the biological significance that?
ad-work [718]

An enzyme possesses different kinetics for different substrates as a result of this different products are formed.

Discussion:

  • Multi-substrate reactions are governed by intricate rate equations that specify how and in what order the substrates bind. If substrate B is altered while the amount of substrate A remains constant, the study of these reactions becomes considerably easier. The enzyme behaves exactly like a single-substrate enzyme in these circumstances, and a plot of v by [S] yields the actual KM and Vmax constants for substrate B.
  • These results can be utilized to determine the reaction's mechanism if a series of such measurements are carried out at various fixed concentrations of A. There are two different sorts of mechanisms for an enzyme that accepts two substrates, A and B, and converts them into two products, P and Q: ternary complex and ping-pong.
