To avoid this u need to drink LOTS of water
Answer:
it could not be used because it can attracts the magnets in which compass it self is a form of magnet which can utilize the magnetic properties of the earth to give a reading and Compass housings are often made of either brass, aluminium or plastic.
Explanation:
The characteristic of iron that would make it a bad material for the housing around a compass is that it could not be used because it can attracts the magnets in which compass it self is a form of magnet which can utilize the magnetic properties of the earth to give a reading reason been that Compass housings are often made of either brass, aluminium or plastic
Secondly it would confuse the magnet thereby making it un-useful or useless because the iron can easily become magnetized itself and Iron is a magnetic metal which can cause the needle of a compass to give a false reading thereby messing up the magnet's direction and making it useless.
Answer:
B. Directional selection
Explanation:
When natural selection starts to choose one phenotypes that is an extreme (as in, a really small neck or a really long neck), this is an example of <u>directional selection.</u> It makes sense for giraffes to have evolved this way, because the longer the neck, the more ably they can eat food from high branches. The more food they could get, the more chance of reproduction, the more "evolutionarily fit" they are.
Stabilizing selection is when national selection picks average phenotypes (like a medium-sized neck). Disruptive selection is when the extremes are both picked (like all the medium-sized neck giraffes die, and two different species start to emerge). Sexual selection is picking a mate based on traits. Clearly, those answers don't work here.
Environments likely to be characterized by the presence of dry scrubs and frequent wildfires are those that lack the presence of rain and suffer high sunlight hours.
When referring to the terrestrial biomes that meet the characteristics described, we can include:
- <u>Temperate grasslands</u>
- <u>Cold deserts</u>
The temperate grassland/cold desert biomes have:
- cold and dry winters
- hot, dry summers
- Extended sunlight hours
This biome is very dry, and the harsh weather makes it difficult for plants to grow, leading to their <em>dry scrub</em> characteristic. This biome also experiences frequent wildfires due to the <u>intense sunlight and lack of rain to which it is exposed.</u>
