This leaves us with four basic emotions, according to this study: happy, sad, afraid/surprised, and angry/disgusted. These, the researchers say, are our biologically based facial signalsâthough distinctions exist between surprise and fear and between anger and disgust, the experiment suggests that these differences developed later, more for social reasons than survival ones.
Time seems to freeze when youâre waiting for a lawn to grow. Most people expect fairly quick results, but the truth is different types of grass germinate at much different rates. Some can be expected to sprout within a week. Others can take almost a month.
Concerning how long does grass seed take to grow, if the conditions are good and the variety of grass used is of the type that grows fast, within a weekâs time the result may be a lush green patch in the lawn. While it may not be properly grown yet the visible result may take about two to three weeks.
