Many tropical zooplankton have elaborate spines. These have been interpreted as either a defense against predation or a means to

increase drag and prevent sinking. How would you determine which was the likely reason for these structures

anastassius [24]3 years ago
3 0

Answer:

Means to increase drag and prevent sinking is the correct answer.

Explanation:

Plankton avoid sinking by increasing their surface area and decreasing their density. Spines slow down sinking by adding surface area without increasing density. Defense against predation would be to sing below. Not the opposite.

Colt1911 [192]

Answer:

The correct answer is e. the passage of electrons from one energy-generating carrier to another

Explanation:

The electron transport chain is a series of proteins and organic molecules found in the inner membrane of the mitochondria. Electrons pass from one member of the transport chain to the next in a series of redox reactions. The energy released in these reactions is captured as a proton gradient, which in turn is used to form ATP in a process called chemosmosis.

These transport molecules, in the inner mitochondrial membrane, are reduced and oxidized, accepting electrons and transferring them to the next molecule, electrons descending from high energy levels to lower ones, that is, from one energy-generating carrier to another. When lowering to other levels, energy is released that will be used in the synthesis of ATP by oxidative phosphorylation.

During perspiration,a. the entropy of the water evaporated decreases and the entropy of the body decreases.b. the entropy of the
Korvikt [17]

Answer:

The correct answer is option c.

Explanation:

Entropy is illustrated as a thermodynamic quantity that demonstrates the thermal energy that does not possess the tendency to get transformed into mechanical work.  

At the time of perspiration, the entropy of the body diminishes because of the evaporation of the water that discharges energy from the body and permits the cooling effect to take place. On the other hand, the entropy of water upsurges as the molecules of liquid converts into vapor form, which captivates larger space in the environment.
