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.
It then has another growing season in spring before summer heat forces it into dormancy. The optimum time for planting depends on when winter weather normally arrives in your area. Fescue grass will take as little as seven days to germinate, but it can take as many as 21 days for maximum germination.
