Materials that can be magnetized, which are also the ones that are strongly attracted to a magnet, are called ferromagnetic<span>(or </span>ferrimagnetic<span>). These include iron, </span>nickel<span>, cobalt, some alloys of rare-earth metals, and some naturally occurring minerals such as lodestone.</span>
Gradual changes in the frequency of diseases over long periods are known as SECULAR TIME TRENDS. For example, the rate of mortality in USA due to coronary heart diseases over a period of time. Onset of puberty in girls is also a secular time trend.
Secular time trend is also referred as Secular Variation and Secular Drift.
Answer:
Proteins are processed and modified in a successive manner to add or remove sugar as they move from cisterna to cisterna.
Explanation:
Golgi apparatus has a flat membrane disk in varies in number in stack, the number can be in between 3 to 20, however six is found in most of them. Cisternae can be separated in four classes cis, medial, trans, and TGN.
Proteins that come from the endoplasmic reticulum in cis type of cisternae after passed through cis to cis and move the protein in order to add or remove sugars to protein.
Thus, the correct answer is - Proteins are processed and modified in a successive manner to add or remove sugar as they move from cisterna to cisterna.
Answer;
Population; physiological modifications at the individual level.
The adaptation of the sled dog best describes adaptation at the population level while the dog exposed to seasonal colder temperatures has physiological modifications at the individual level.
Explanation;
-The bodies of sled dogs are covered with two coats of hair that work together to provide a double layer of warmth. The under layer is very short and the dog sheds it in the spring to keep from overheating during warmer temperatures.
-During the colder winter months, this under layer works as an insulator against the dog's skin to keep his body warm and his core body temperature consistent. This adaptation best describes adaptation at the population level while the dog exposed to seasonal colder temperatures has physiological modifications at the individual level.
Actually, it is false. P-waves arrive first and then S-waves arrive.
