| Can bacteria, viruses, etc. get diseases just like humans or plants? Posted: 18 Aug 2020 03:41 AM PDT If bacterium, viruses, fungi, etc cause disease, can they themselves get a disease? [link] [comments]  |
| How do they load operating systems onto completely blank computers? Posted: 18 Aug 2020 06:49 AM PDT Say I have a computer that is just the absolutely bare electronics. Nothing to read a usb or any inputs. How would I load an operating system onto it? How do computer manufacturers accomplish this? [link] [comments]  |
| How far up do helium filled balloons go? What is their limit? Posted: 17 Aug 2020 07:00 PM PDT I'm sure we have all lost a balloon or got one that's blew away but how far into the sky does it actually go? You can keep a regular balloon for about a week and Itll still stay floating around your house but when it gets released into the sky does an actually make it through any of the "spheres" or does the volume of the helium prevent it from breaking through?

| As a female, does losing your virginity actually change your body in any way? Posted: 18 Aug 2020 07:50 AM PDT I always see these strange dads obsessed with hymens being intact which made me wonder: is there actually a visible change to the body when virginity is lost? [link] [comments]  |
| Does Enceladus have sub-surface continents? Posted: 18 Aug 2020 12:54 AM PDT I read in a handful of pages that Enceladus is geologically active, referring to tectonic activity in the South polar region. Since the moon has tectonic plates does this mean that the formation of features along boundaries, and the existance of continents or a supercontinent is possible? [link] [comments]  |

| Is it possible to achieve a ‘negative’ shockwave? Posted: 17 Aug 2020 03:11 PM PDT Aside from explosive lenses, is an implosive shockwave actually possible? As in, a region that decreases air pressure so rapidly, that rarefaction can occur faster than the speed of sound, inwards spherically? I understand that traditional explosives can create major shockwaves because their detonation velocities are many times Mach 1, however slower objects like fighter jets and whips can still achieve it to a significant extent. Edit: what I really mean is a near instantaneous decrease in air pressure by a shrinking mass at the centre of an infinite volume of atmospheric pressure air. Rather than beginning with higher pressure air compressing an air mass at 1atm, like a traditional explosive would do. In addition, what would it sound like? I assume that if you're close enough, it'll be similar to a bang from the opposite direction, but at a distance, is it just the sound of a reverberated sonic boom? Or would it be identical as the pressure waves pass through each other? [link] [comments]  |
| Does Lighting emanate from a single point in a cloud? Posted: 17 Aug 2020 04:40 PM PDT To clarify: I am aware that stepped leaders come down from the cloud, and that current from ground connects to a leader, followed by a massive stroke going upwards. As well as leaders can come from the ground occasionally, different processes exist for cloud to cloud lightning, sprites are a thing, etc. The specific question is, when electricity moves from or to a cloud, since there is no solid surface there, from where does this electron flow flow from, or to? Is it a diffuse area that spreads out in voltage? Visually how would this process appear to a camera somehow stationary in the sky that happened to be looking at the right direction and at the right distance? [link] [comments]  |
| What is the current pandemic effect on Global Warming?? Posted: 18 Aug 2020 01:20 AM PDT In this pandemic where most of the countries are in halt, causing less pollution to mother earth, are there any recent studies that show that earth is healing from global warming or the difference in pollution level has not much changed since pre-pandemic to now??

| Do caterpillars have a sex before they pupate into moths/butterflies? Posted: 17 Aug 2020 01:41 PM PDT The question popped up on a recent post on r/CasualUK on a pic of an interesting looking caterpillar. [link] [comments]  |
