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.
Often times hydroseeded lawns will begin to germinate is as little as 7-14 days. Most grass types will take between 3-4 weeks to fill in and depending on how often the lawn is watered, and the type of grass seed used, it can take up to as much as 8 weeks to see strong growth. Don't forget to fertilize after 4 weeks.
