In the temperate latitudes, a continental climate is usually characterized by a large annual range of air temperature (hot summers and cold winters) and considerable daily variations in air temperature. A continental climate differs from a marine climate in having a low mean annual temperature, low humidity, and dustier air.
Squamous cells area one single layer and flattened, this allows for diffusion of oxygen and carbon dioxide to happen easily in the lungs.
Well, first off the spongy mesophyll does have some chloroplasts, however they are located quite far from the surface of the leaf where most of the chloroplasts are. Therefore they don't get much light and don't contribute a lot to photosynthesis in the leaf. So why should the leaf waste the energy in making chloroplasts if there is not enough light to make them all efficient enough at photosynthesis?
Answer:
They fall from the clouds as ice crystals.
They form around particles in the atmosphere.
They form when water vapor is converted directly to ice crystals.
Explanation:
Answer:
Nucleoid
Explanation:
Prokaryotes are unicellular organisms that lack organelles or other internal membrane-bound structures. Therefore, they do not have a nucleus, but, instead, generally have a single chromosome: a piece of circular, double-stranded DNA located in an area of the cell called the nucleoid.
