Blood clots can present as red tender lines on the legs or they can develop silently and grow extensively in the deep veins of the leg before being discovered. They are suspected by the physician when there is swelling or pain in just one leg that is not explainable by any other cause such as an injury or other event.
Thiol with a blue-highlighted sulfhydryl group. In organic chemistry, a thiol (/ËÎ¸aÉªËÉËl/ , /ËÎ¸aÉªËÉl/) is an organosulfur compound that contains a carbon-bonded sulfhydryl (âCâSH or RâSH) group (where R represents an alkane, alkene, or other carbon-containing group of atoms).
Redvine (Brunnichia ovata) tendrils coil upon contact. Thigmotropism is a directional growth movement of curvature which occurs in response to stimulus of contact. Thigmotropism is found in twining plants and tendrils. After initial contact with support due to nutation, the tendril or twiner shows less growth in the region of contact and more growth on the opposite side. As a result, they bend around the support.
