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.
Newly seeding grass should germinate in 9-14 days. After germination you'll need another 4-6 weeks for it to grow to the point where it can be mowed. Keep new seeds moist but not soaked. Keep new grass well watered but not soaked. After the first mow, you can treat it like regular grass.
