In 121 BC, Rome came into contact with two Celtic tribes (from a region in modern France), both of which they defeated with apparent ease. The Cimbrian War (113101 BC) was a far more serious affair than the earlier clashes of 121 BC. The Germanic tribes of the Cimbri and the Teutons migrated from northern Europe into Rome's northern territories, and clashed with Rome and her allies. At the Battle of Aquae Sextiae and the Battle of Vercellae both tribes were virtually annihilated, which ended the threat.
In what year did Rome come into contact with a couple Celtic tribes?
A: 121 BC

This is fortunate, since antennas at lower frequencies which are not rather large (a good fraction of a wavelength in size) are inevitably inefficient (due to the small radiation resistance Rr of small antennas). Most AM broadcast radios (except for car radios) take advantage of this principle by including a small loop antenna for reception which has an extremely poor efficiency. Using such an inefficient antenna at this low frequency (5301650 kHz) thus has little effect on the receiver's net performance, but simply requires greater amplification by the receiver's electronics. Contrast this tiny component to the massive and very tall towers used at AM broadcast stations for transmitting at the very same frequency, where every percentage point of reduced antenna efficiency entails a substantial cost.
How would this antenna rate in the greater scheme of things?
A: little effect

The act of predation can be broken down into a maximum of four stages: Detection of prey, attack, capture and finally consumption. The relationship between predator and prey is one that is typically beneficial to the predator, and detrimental to the prey species. Sometimes, however, predation has indirect benefits to the prey species, though the individuals preyed upon themselves do not benefit. This means that, at each applicable stage, predator and prey species are in an evolutionary arms race to maximize their respective abilities to obtain food or avoid being eaten. This interaction has resulted in a vast array of adaptations in both groups.
At most there are how many step of predator-prey interaction?
A:
maximum of four stages
