Answer:

Biome 1: Arctic Tundra

Organism 1: Arctic Fox

Explanation:

1. This organism can be found in a cold, snowy ecosystem with long winters and short summers.

2. The Arctic Fox is at the top of the food chain, so it has a small amount of predators. It's population would increase if there were no predators to hunt them. This would affect the ecosystem by causing a sudden decrease in the Arctic Fox's prey.

Which explains how interference is avoided between the signals that cordless phones receive and the signals that they broadcast?
aliya0001 [1]

Answer:

the signals have different frequency

Explanation:

The way that interference is avoided in these cases is that the signals have different frequency. Cell phone signals travel in a very specific wavelength, how often this wave repeats in a given span is called the frequency. By having these signals in different frequencies it prevents the signals from mixing with each other and instead allowing them to reach their destination intact. Otherwise, the signals would combine into a mess of uncomprehensible data, which is what we call interference.

What is the percentage of calories were absorbed by your system??? Helpppp
denpristay [2]
Calories in and of themselves aren't a reliable way of describing energy density in food. It doesn't reflect what actually happens in your body (look up bomb-calorimeter for how people figure out calorie content in foods). So based on this, the question is a bit of a non-sequitur. But if you disregard that and go with a regular answer, it really depends on what kind of calories you're ingesting because foods get digested in a function of different amounts of time. Carbohydrates will get digested and converted into glucose almost immediately - being very close to 100% energy efficiency. Fats are the slowest as your body needs to produce bile in order to digest it - not enough bile = undigested fat = unused calories. Proteins are turned into either amino acids (not an energy source per se) or converted into glucose like carbs but instead through gluconeogenesis which is a less efficient form of glucose conversion than carbohydrates (since your liver/kidneys need to produce the enzymes to convert it). The efficiency of protein is likely in the range of 50-60% calories. This is just the tip of the iceberg though - your metabolism also plays a part as to how much and when these calories are either used, stored, and excreted by your body. Ever got the meat sweats? That's your body burning excess energy through thermogenesis when you eat too much protein. So it really depends why you're asking because the answer will differ for each scenario.
