Los corticoides se emplean para tratar los síntomas producidos por un brusco descenso de los niveles de corticoides en el organismo, por ejemplo en la enfermedad de Addison. También presentan un gran poder antiinflamatorio. En ocasiones, por distintos estímulos, algunas células de nuestro cuerpo liberan unas sustancias que provocan inflamación. Los corticoides al reducir la liberación de estas sustancias ante, por ejemplo, respuestas alérgicas o inmunes, reducen a su vez la inflamación. Por tanto, los corticoides serán útiesl en enfermedades que se caracterizan por una inflamación excesiva.
The correct answer is C. More helium and less hydrogen
Explanation:
The Sun, which is the center of the solar system, is mainly composed of two gases: hydrogen and helium. Additionally, every second and through nuclear fusion the hydrogen is fused and this creates helium, which is a heavier element. This implies as the sun ages the amount of hydrogen will decrease as the amount of helium increases, as a result of constant nuclear fusion. Indeed, right now helium exists in a lower quantity than hydrogen, but every second, minute, hour, etc. the amount of helium increases, and it is expected in millions of years there is more helium than hydrogen.
Answer:
The light speckled moth
Explanation:
<em>Biston betularia</em> or peppered moth is a moth that is very commonly present in Asia, Europe and North America. Normally it occurs in two forms:
1) A dark morph
2) A light, speckled morph
The peppered moths are a frequent target of birds but they are smart enough to rescue themselves against predator birds by selecting appropriate location for their habitats. For example: If a forest contained mostly light colored trees , light, speckled morphs will be more abundant there because due to a matching color with trees they will be less visible to birds and other predators. Similarly, If a forest contained mostly dark colored trees,dark morphs will be more common so that they rescue themselves due to camouflage from the attack of birds.
Hope it help!
This case of mistaken identity called imprinting. The best-known form of imprinting is filial imprinting, in
which a young animal acquires several of its behavioral characteristics from
its parent. It is most obvious in nidifugous birds, which imprint on their
parents and then follow them around.
