The sensory-somatic nervous system consists of the cranial and spinal nerves and the autonomic nervous system consists of sensory and motor neurons between the CNS and the internal organs. The Autonomic Nervous System. The autonomic nervous system vs somatic nervous system distinction is functional: While the somatic nervous system is…
Yes, you can. In fact, they encourage you to use your own travel mug at Starbucks. But not that many people actually do it. And that’s because there are a few misconceptions. We’ll clear some of those up and show you why it is always a great idea to bring…
Spirochetes are gram-negative, motile, spiral bacteria, from 3 to 500 m (1 m = 0.001 mm) long. Spirochetes are unique in that they have endocellular flagella (axial fibrils, or axial filaments), which number between 2 and more than 100 per organism, depending upon the species. Spirochetes (spirochaetes) are Gram-negative, spiral-shaped…
The fact that moons form stable orbits around planets, planets form stable orbits around stars, and stars form stable orbits around galactic centers is direct observational evidence that moons, planets, and stars all have a total electric charge of zero. Stars spend most of their lives repetitively compressing two hydrogen…
In order obtain food, sponges pass water through their bodies in a process known as filter-feeding. Water is drawn into the sponge through tiny holes called incurrent pores. Some creatures don’t have to go anywhere at all to filter feed, though. Sponges are inanimate, but they have a water current…
Star-forming regions are a class of emission nebula associated with giant molecular clouds. These form as a molecular cloud collapses under its own weight, producing stars. Massive stars may form in the center, and their ultraviolet radiation ionizes the surrounding gas, making it visible at optical wavelengths. First, I need…
A longitudinal wave is one where all the particles of the medium (such as gas, liquid or solid) vibrate in the same direction as the wave. Sound waves are longitudinal waves. a. Transverse wave : A wave in which particles of the medium vibrate in a direction perpendicular to the…
Spores are highly resistant to dehydration damage, and part of this resistance appears to be due to small acid-soluble spore proteins (SASP) which bind to DNA to protect it against dehydration damage, which may involve oxidative damage (Fairhead et al., 1994). This article will discuss the factors involved in spore…
Steam humidifiers are the most effective, but are more costly to install and operate. If you have high end wood furniture, flooring, have a large home, or need precise humidity control, steam humidifiers are the best option. They require a dedicated electrical service and need annual maintenance. Steam humidifiers can…
Unless someone is saying, “Boom”, don’t put it in quotes. Alright, but if we say the sound is made of a meteor hitting the ground, I should use some kind of punctuation right? You might choose to put that in italics: Boom! The meteor cratered into the ground producing a…
