Ave you ever wondered why one area of the world is a desert, another a grassland, and another a rainforest? Why are there different forests and deserts, and why are there different types of life in each area? The answer is climate.
<span>Climate is the characteristic condition of the atmosphere near the earth's surface at a certain place on earth. It is the long-term weather of that area (at least 30 years). This includes the region's general pattern of weather conditions, seasons and weather extremes like hurricanes, droughts, or rainy periods. Two of the most important factors determining an area's climate are air temperature and precipitation. </span>
We know that <span>is evidence that supports assimilation and multiregional evolution models for modern human evolution. This multiregional evolution is an hypothesis based on a scientific model that is in itself an alternative explanation o human evolution. Part of this claims that the neandertals can be accepted as homo sapiens which is widely debated by many of the scientist. </span>
Answer:
The binding of acetylcholine to its receptor activates the muscle and causes a muscle contraction. In myasthenia gravis, antibodies (immune proteins produced by the body's immune system) block, alter, or destroy the receptors for acetylcholine at the neuromuscular junction, which prevents the muscle from contracting
Analogous structures have different evolutionary ancestries but have the same function. some types of structures are the wings of birds, bats and insects. Homologous structures are the opposite, they have similar ancestries and common traits but not the same function.
