How do you kill a kangaroo rat? Trapping with snap traps is probably the most efficient and humane method for kangaroo rats. Mouse traps will suffice for smaller animals, but Victor® “museum specials” or rat traps are needed for larger kangaroo rats, particularly the bannertail. Why do kangaroo rats not drink water? Because their habitats […]
What are two different types of electron microscopes?
What are two different types of electron microscopes? There are two main types of electron microscope – the transmission EM (TEM) and the scanning EM (SEM). The transmission electron microscope is used to view thin specimens (tissue sections, molecules, etc) through which electrons can pass generating a projection image. What is the greatest advantage of […]
What are skin macrophages that help activate the immune system?
What are skin macrophages that help activate the immune system? Dendritic cells Skin macrophages that help activate the immune system. What are the five layers of the epidermis? The layers of the epidermis include the stratum basale (the deepest portion of the epidermis), stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum (the most superficial […]
What is difference between IR and UV?
What is difference between IR and UV? IR and UV radiation are a small part of the electromagnetic spectrum. The visible light has a wavelength of 380 nm to 760 nm. The area alongside with a longer wavelength is the IR spectrum. The area next to the visible light, with a shorter wavelength, is the […]
What is the charge on each plate of the capacitor?
What is the charge on each plate of the capacitor? Capacitors do not store charge. Capacitors actually store an imbalance of charge. If one plate of a capacitor has 1 coulomb of charge stored on it, the other plate will have −1 coulomb, making the total charge (added up across both plates) zero. Can there […]
What is the electromagnetic spectrum used for?
What is the electromagnetic spectrum used for? Nearly all frequencies and wavelengths of electromagnetic radiation can be used for spectroscopy. Radio waves, infrared rays, visible light, ultraviolet rays, X-rays, and gamma rays are all types of electromagnetic radiation. Which color is the most refracted? violet light What is required for refraction? For refraction to occur […]
Is La Nina related to climate change?
Is La Nina related to climate change? In a warming climate, rainfall extremes are projected to shift eastward along the equator in the Pacific Ocean during El Niño events and westward during extreme La Niña events. Will 2020 be the hottest year on record? Globally, 2020 was the hottest year on record, effectively tying 2016, […]
What are some interesting facts about the Alpine biome?
What are some interesting facts about the Alpine biome? It is cold, snowy and windy. It is usually below freezing at night. Alpine biomes are located on mountains. They are below the snow line…. Quick Facts Location on mountains; above 10,000 feet Area of coverage 16% of earth’s surface 31,510,000 square miles (81,610,000 square kilometers) […]
What are the 4 types of equilibrium?
What are the 4 types of equilibrium? There are three types of equilibrium: stable, unstable, and neutral. Figures throughout this module illustrate various examples. Figure 1 presents a balanced system, such as the toy doll on the man’s hand, which has its center of gravity (cg) directly over the pivot, so that the torque of […]
Can you have an extra chromosome and be normal?
Can you have an extra chromosome and be normal? Most commonly, some cells end up with one extra or missing chromosome (for a total of 45 or 47 chromosomes per cell), while other cells have the usual 46 chromosomes. Mosaic Turner syndrome is one example of chromosomal mosaicism. How do you know if you have […]
