When was the first mass extinction?
540 million years ago was the first mass extinction
Two features that distinguish matter are?
Two features that distinguish matter are its mass, which is the amount of matter in an object, and its volume, which is the amount of space the object occupies. These characteristics help identify and classify different types of matter.
What was the outcomes of each of the mass extinctions?
The outcomes of each of the mass extinctions is that animal and/or bacteria die.
What is the average mass of a bird?
what is the mass of a robin? 25cm-77grams 124.7mm
What is dry mass?
Dry mass refers to the weight of an object or substance after all moisture and volatile components have been removed. It is a measure of the solid content of the material without any water or other liquids. Dry mass is often used in scientific research to accurately measure the amount of a specific substance present.
What is a buccal mass?
The buccal mass on a squid contains the beak used for eating.
Why is the beak of the squid embedded in the buccal mass?
The buccal mass is actually made up of the muscles which move the squid's beak and radula. Here are a few pictures I took of a humboldt squid buccal mass being dissected that may help you understand the structure... http://www.flickr.com/photos/34681395@N00/879924797/in/set-72157600912901870/ http://www.flickr.com/photos/34681395@N00/879934117/in/set-72157600912901870/ http://www.flickr.com/photos/34681395@N00/879921833/in/set-72157600912901870/ http://www.flickr.com/photos/34681395@N00/880772690/in/set-72157600912901870/ http://www.flickr.com/photos/34681395@N00/879922729/in/set-72157600912901870/
What are three Squid facts about there intelligence?
Squids and other cephalopods have shown response to classical conditioning. Some squid use changes in skin color and pattern to communicate messages. Squid and octopi have the largest brain-to-body mass ratios of all invertebrates.
What is the brachial ganglia of the squid?
Like humans, cephalopods like squid have highly developed nervous systems. However, they are organised very differently to those of vertebrates, being far less centralised. In squid and octopuses, a large proportion of their neural mass is located in their arms, rather than what would be traditionally considered their brain. The Brachial ganglia are simply the large neural masses that are found in the arms of the squid, giving each tentacle a large degree of independence, and operating alongside the brain.
In which body region are most of the squid's organs located Why do you think so?
Most of a squid's organs are located in the visceral mass, which is situated in the central body region called the mantle. This compact arrangement allows for efficient protection and organization of vital organs, enabling the squid to streamline its body for swimming and hunting. Additionally, having the organs centralized in the mantle helps maintain buoyancy and balance in the aquatic environment.
The heaviest invertebrate is the giant squid which is estimated to have a weight of about 2 tons spread out over its length of 70 feet. What is its weight in newtons?
The weight of the giant squid can be calculated by using the formula: weight = mass x gravity. Since weight is a force measured in newtons, the weight of the giant squid would be about 19,620 newtons (2 tons x 9.81 m/s^2).
How many pages is the book tentacles?
The mass market paperback of Tentacles has 336 pages. It is a fun read about Marty and Grace searching for a giant squid. It was written by Roland Smith.
How ice can weather rock?
In one way (ice wedging), water gets into cracks in the rock, then freezes. This force can eventually split the rock crystals. In another (moving ice), a glacier or other large mass of ice moves across the rocks surface. This can scour away loose rock by friction. (It does not require that there be imbedded rocks, but this can also occur, where rocks are pushed together until one breaks.)
How did the vampire squid get its name?
-- Vampyroteuthis infernalis, "the vampire squid from hell," got its name from its most obvious characteristics. It is typically a deep red, but some have been found which are nearly black. Its arms are lined with hooks instead of suckers. Its arms are attached, much like an octopus, and when its arms are outstretched this resembles a cape (much like Vampires are said to wear). It can throw this cape over it's body so it is just a mass of arm hooks, frightening off potential predators. --
How is mass different from mass?
Mass and mass are the same thing.
How do you find a mass by difference?
Mass of the contained material = Total mass (mass of the container + mass of the material) - Mass of container
What is the formula for mass percent?
mass % of element X = mass of element X ____________________ X 100 total mass of compound or mass of solute _____________________________ X 100 mass of solute + mass of solvent
