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.
The species of grass seed you sow will help to determine when to expect germination. Ryegrass is the quickest species of grass to germinate. In the correct conditions, ryegrass can germinate in 5-7 days, usually 10-14 days if it is not too cold (see above!). Tall, chewings and creeping fescues are the next species to germinate, usually 14-21 days.
