Answer:
Vainas sinoviales tendinosas
Explanation:
Las vaina tendinosas o vainas sinoviales son mangas de tejido de protección que se encuentran alrededor de las articulaciones o rodean a los tendones. Estas vainas permiten que los tendones se deslicen suavemente, produciendo un líquido (líquido sinovial) que mantiene al tendón lubricado. De este modo, las vainas tienen como función evitar el roce entre el tendón y el hueso. Las vaina tendinosas conforman un revestimiento de dos capas: una interna unida al tendón y una externa de tejido conectivo.
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.
He was looking through a microscope at particles trapped in cavities inside pollen grains in water. The concept of Brownian motion is named after him. This is the random motion of particles suspended in a fluid, liquid or gas resulting from their collision with the fast-moving molecules. Here, the patterns of motion of the particles are typically alternations between random fluctuations in a particle's position inside a fluid sub-domain with a relocation to another sub-domain. Each relocation is followed by more fluctuations within the new closed volume.
