Do Plants Feel Pain? | XYZspot

Given that plants have no pain, nerves, or brains, they don’t feel pain in the way we in the animal kingdom understand it. Pulling carrots or pruning hedges isn’t a form of plant abuse, and you can safely bite the water. But it turns out that many plants can sense and communicate physical stimuli and…

Why Do Some Animals Hibernate? | XYZspot

Why Do Some Animals Hibernate? | XYZspot

Some animals hibernate during the winter months because food is scarce. They go into a long slumber, skipping the morning hours when food is more plentiful (because their body temperature doesn’t drop), but many animals have taken advantage of this change, including jerboas, little brown bats, Eastern chipmunks, prairie dogs, and some species of squirrels. At least one species of bird is thought to hibernate; the poor wren of western North America. Know when it’s time to prepare for hibernation. While the exact mechanisms are unknown, shorter days, reduced food intake, and cold weather all seem to affect HIT, and build up large stores of white and brown fat in the body to help them get through it. Brown fat provides body heat and energy when the animal wakes up. Some animals also store food in their burrows to eat during brief periods of wakefulness. In fact, significant physiological changes occur in the body during hibernation. The animal’s body temperature drops, and its breathing and heart rate slow down. The effects can be so severe that hibernating animals appear to be dead. In regions with mild winters, animals may hibernate for only brief periods or not at all. During the long hibernation period, many animals wake up briefly to go to the bathroom and have a snack before going to sleep. Some bears are unique in that they do not wake up, eat, drink, or go to the bathroom during hibernation, which can last for months.

How Fast Is the Universe Expanding? | XYZspot

How Fast Is the Universe Expanding? | XYZspot

The rate of expansion of the universe is called the Hubble constant, named after astronomer Edwin Hubble, who, with Milton Harmarson, discovered that galaxies are receding from Earth at a speed proportional to their distance. So speed = Hubble constant × distance. Rearranging this equation gives Hubble constant = speed × distance, so the Hubble constant is expressed in kilometers per second (km/s) per megaparsec (Mpc), where one megaparsec is 3.26 million light-years. > So what is it? How big is the universe? In 1929, Hubble obtained a value of about 500 km/s/Mpc. By 1960, accurate measurements had reduced this speed to 100 km/s/Mpc, but the astronomical community was divided into two camps, those favoring 100 km/s/Mpc and those favoring a similar 50 km/s/Mpc. Resolving this issue became a major task of the Hubble Space Telescope (HST). It took only a few years. Recent accurate measurements of the cosmic microwave background give a value of about 68 km/s/Mpc, while measurements using observations from the HST still give a value of about 72 km/s/Mpc. This disagreement is called the “Harber tension” and has not yet been resolved.

What's the Difference Between a Solstice and an Equinox? | XYZspot

What’s the Difference Between a Solstice and an Equinox? | XYZspot

You may know that the summer solstice and spring equinox signal the changing seasons of the world, but do you remember which one? Are they different names for the same thing? Solstices and equinoxes are actually opposites. This means that different parts of the world receive more or less sunlight at different times of the year. If the world were not tilted, the sun would be directly above the equator, the light coming to the center would be constant, and there would be no seasons. You should also mark the equinoxes or solstices. . On this day, the sun’s path across the sky is as far north or south as it is from the equator. The winter solstice is the shortest day of the year in the hemisphere, while the summer solstice is the longest day of the year. In the Northern Hemisphere, the June solstice marks the beginning of summer: when the North Pole is closest to the sun, and the sun’s rays shine directly over the Tropic of Cancer. December marks the beginning of winter: when the South Pole is closest to the sun, and the sun’s rays shine directly over the head of the Tropic of Capricorn. (The seasons change in the Southern Hemisphere.) The equinoxes occur in March (around March 21) and September (around September 23). On this day, the sun is directly above the equator, and day and night are of equal length. The Earth orbits the sun; Vernal Equinox (around March 21): Day and night are of equal length, marking the beginning of spring Summer Solstice (June 20 or 21): Long days for most of the year, marking the beginning of summer Autumn Equinox (around September 23): Day and night are of equal length, marking the beginning of autumn. Winter Solstice (December 21 or 22): The shortest day of the year, marking the beginning of winter.
