What is the difference between arterial and venous bleeding?

One of the most significant differences between these types of bleeding is the severity, according to the Stony Brook University. The arteries are under high pressure, so the blood gushes out rhythmically with the heart beat, making the bleeding very dangerous and hard to control. The veins, however, are under low pressure, causing a slow and steady bleeding.\nAccording to Wikipedia, the blood color can also help determine the type of bleeding. Arterial blood that is rich in oxygen is bright red, while venous blood is dark red.

Is fungi prokaryotic or eukaryotic?

Eukaryotic cells arose from prokaryotic cells and have a more complex organization than prokaryotic cells. Much of the activity of prokaryotic cells takes place in the cytoplasm. The activities in eukaryotic cells happen in enclosed structures called organelles. The DNA of eukaryotic cells is contained within their nuclei, whereas the genetic material of prokaryotes floats around in the cytoplasm. Some of the membrane-bound organelles found in fungi include nuclei, mitochondria, Golgi bodies and ribosomes.

Where can you find the times of meteor showers?

AMSMeteors.org also gives the dates of when meteor showers are active. Visitors can learn the radiant, zenith hourly rate, velocity and parent object of each meteor shower. The website also lists the moon phases of the meteor showers, as sometimes when the moon is more than half illuminated, the meteor showers become hard to see. AMSMeteors.org notes that the meteor showers it lists are best seen after midnight.

How does salt melt ice?

Ice usually has a thin layer of water coating its surface. Molecules from the ice are constantly slipping off the ice and escaping into the liquid water (melting). At the same time, molecules from the water are continually getting stuck on the solid ice (freezing). When the temperature of the ice is 32 degrees Fahrenheit, the processes happen at the same rate and the amount of ice and water doesn’t change.\nWhen salt is added to the water-coated ice, it dissolves into the liquid water but not into the solid ice. This affects the balance between the freezing and melting rates. Now there are f..

What types of plants can you grow in a hydroponic system?

Growing vegetables via a hydroponic system allows them to grow year-round and produces a larger yield in a shorter amount of time. Growing them hydroponically also takes up considerably less space. Types of vegetables that do well in a hydroponic system include artichokes, celery, beets, carrots and eggplants. Tomatoes are one of the most popular plants grown in a hydroponic system as they ripen eight weeks earlier on average and produce a greater yield.\nFruits also usually grow well in a hydroponic system, although gardeners should be sure to follow the specific care instructions for each pl..

What is the relationship between distance from the sun and period of revolution?

Kepler’s third law compares the orbital period and the radius of an orbit of a planet to the distance of the planet to the sun. It states mathematically that the more distant a planet is from the sun the greater its orbital period will be. The period of revolution of a planet is measured in days, weeks, months or years. For example, Earth’s period of revolution is 365 days.

What exactly is a light year?

The light year is usually used when expressing the distance between two astronomical objects, such as stars. A light year measures how far light travels in the Julian calendar year, or 365.25 days. Light travels at 299,792,458 meters per second. This means that light travels 9,460,528,400,000,000 meters in a year. So, a light year is equivalent to 9,460,528,400,000,000 meters. A single light year is so large it can circle around Earth about 236,070,578 times.

What is a nucleation site?

One example of nucleation is water droplets condensing out of the air to form clouds. In order for the water to condense, the vapor first has to cool. This happens as air masses rise farther from the earth's surface. After the air cools, it still does not condense unless a nucleation site is available. In the atmosphere, nucleation sites are provided by small dust particles and bits of sea salt or soot. The water vapor in the air condenses into droplets on these tiny particles, and clouds form.

What is the definition of "Mendel's law of independent assortment"?

Mendel determined the law of independent assortment when he studied the genetics of pea plants. By crossing plants that were heterozygous for particular traits, Mendel was able to trace different alleles passing through the generations of offspring based on the ratios of offspring that had particular traits.\nIn the cases that Mendel studied, the pea plant traits had two types or alleles. The dominant allele determines the trait if it is present, even if the other allele is recessive. The recessive allele can only be viewed in the offspring if both chromosomes of the plant have the recessive a..

Which event occurs during interphase?

The Collin County Community College District details that interphase comprises three periods: the G1 phase is the first growth phase; the S phase is the synthesis phase, in which DNA is synthesized while chromosomes are duplicated; and the G2 phase is the second growth phase. The characteristics of a G2 cell include a well-defined nucleus bounded by a nuclear envelope, two centrosomes next to the nucleus, one or more nucleoli, duplicated chromosomes, and a pair of centrioles in every centrosome and a radial mictorubular array around the centrioles, in animals.\nThe University of Pittsburgh at ..
