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.
When you plant grass seeds, it is important to match the grass species to your local climate and plant the seeds at the correct time and rate. To get a rough idea how long for your lawn to get established, add 30 to 45 days to the germination time. Annual ryegrass (Lolium multiflorum) and perennial ryegrass (Lolium perenne) seeds germinate in five to 10 days. Rough bluegrass (Poa trivialis) seeds take seven to 10 days. Tall fescue (Lolium arundinaceum) seeds germinate in seven to 12 days.
