Saltwater slugs also known as sea slugs have evolved a number of strategies to protect their bodies from danger. One of the main methods they use is camouflage which helps them blend into their surroundings to avoid predators. In addition they have thick slimy mucus that covers their body and makes them difficult for predators to grip. Other strategies include:
- Producing toxins which can help ward off predators.
- Producing foul-tasting chemicals that make them unappetizing to predators.
- Engaging in defensive posturing such as rearing up to appear larger and more intimidating.
- Using their gills to release clouds of ink that can confuse or disorient predators.
These strategies help saltwater slugs survive and thrive in their marine environment.

Is it true that if you poor salt on a slug it will melt?
Well, it will not melt. First, it will look like it is in severe pain. Then, it will explode!
Whats 2 examples of chemical energy?
(more than two) Chemical Energy Examples: Digestive process, batterys, photosynthesis, burning gasoline, burning wood, using TNT, fire works, putting salt on a slug, alchohol, fermintation, rusting. (all of those answers where aproved by my physical science teacher)
Why the packing material of ferrous ascorbate and folic acid tablets swells with time?
As far as I understand it swells because of oxidation process is going on inside tablets thus releasing gaseous substance. In worse condition tablet cracks sometime. I think water or humidity is to be avoided during its formulation. Compacted api is prefered. Slug-deslug to be done. Some good antioxident like BHA, BHT, SMBS to be used. And moisture barrier pre coat before final coating to be done
What is the mass of an egg in water?
It totally depends on where the egg is coming from and how far along it is in development. An ostrich egg can be about 1.5 kg or over 3 lb. Humans and fish also produce eggs. A chicken egg can be a range of sizes depending on the variety of chicken. The average longhorn egg that can be bought in the supermarket can vary between 40-45 g to 65 g. The typical weight of a large egg is 0.057 pounds. ______ Don't get confused with weight and mass. The eggs weight, in pounds, is a force. This is how much the earth pulls on the egg. The egg's weight would vary depending if it was on the earth or the moon. The mass of the egg, however, does not vary. It's the same regardless of where the egg is. Instead of measuring a force, mass measures how much matter the egg is made of. To find the mass of the egg, all you need to do is use the equation: "Force = mass * acceleration". Rearrange the equation and you get "mass = force/acceleration" So mass = (0.125 pounds)/(32 feet per second squared). This means the mass of the egg is about "0.0039 slugs". Yep, the unit of mass in the non-standard unit system is the slug. To confuse you even more, if you see an object whose "weight" is measured in kilograms, you're actually being given the mass of the object. In the standard system, the unit of weight is the Newton. So in other words: Weight is either in pounds or newtons, and mass is either in slugs or kilograms. The mass of an egg is 0.0039 slugs, which is the equivalent of 0.0569 kilograms. In New Zealand, eggs are sold as No6, No7, and so on. This number is the number of hundreds of grams of 1 dozen eggs. Still sold in dozens for convenience in packaging.
How do neutrons make nonradioactive elements radioactive?
The process of making materials radioactive by neutron bombardment is usually referred to as neutron activation. Neutrons are generally found in abundance within the cores of operating nuclear reactors where it is the neutron flux that is causing the fission chain to continue. These neutrons can be used to activate stuff. There are whole books on this subject. We'll tackle it here with a few paragraphs, so let's go. There is a funny group of rules associated with the way an atomic nucleus reacts to an incoming neutron. It isn't necessarily like breaking a rack of billiard balls like in so many science shows. It's more like the neutron manages to press up against the nucleus and the nucleus captures it. Then what happens, happens. One of the concepts to be considered is the energy of the incoming neutron. How fast is it going? (Faster isn't necessarily better for increasing the probability of capture.) Another is the size of the target that a given nucleus presents to that neutron. We call that a neutron absorption cross section, and it's measured in barns. (Yes, like the broad side of a barn, as in hitting the broad side of a barn. And who said physicists weren't funny and couldn't make jokes!) There are tables to look this stuff up on because each given isotope has a given neutron capture cross section, just like you'd imagine. One little (or no-so-little) thing is that different isotopes of the same element have different neutron capture cross sections. That ups the challenge for investigators. What happens is that the neutron is captured and all the nucleons (the protons and neutrons that are in the nucleus) must now make up a new contract as to how they are all gonna share this tiny little space where they are all crammed in. You remember that the protons and neutrons in an atomic nucleus are all smooshed together and all of them have given up a bit of mass and that mass has been converted into binding energy or nuclear glue to hold the whole thing together, right? Well, all that went out the window when the new kid arrived on the block. New arrangements have to be made. Depending on the element and the particular isotope of that element that captures a neutron, a number of different things can result. If the neutron is actually captured and there is no stable isotope of that element possible with the "new" configuration, it disintegrates. Disintegration schemes vary, as one might guess. If a stable isotope results, so be it. (It's stable.) If an unstable isotope results, it is radioactive, and rules apply for its decay. The table of nuclides holds the particulars. If a neutron is captured by a fissionable isotope, it fissions. The result will be fission fragments, a neutron or neutrons, and some other stuff. Hit the links and check out the particulars. An example of irradiation by neutrons (activation) might be cobalt. A little slug of cobalt is welded up inside a skin of stainless steel and then the pellet is dropped into an operating nuclear reactor to give it a neutron bath. Cobalt metal is almost entirely cobalt59 which is the only stable isotope. And it presents a big target to an incoming neutron. When it collects an extra neutron, presto! Cobalt60, which is highly radioactive with a 5.2 year half life. We reel in our little pellet of cobalt60 and put it inside a lead lined casket that has a little door. Now we stick labels all over the thing warning folks to leave it the heck alone. Then we truck it out to a job site where welding work has to be x-rayed. We set the thing up pointing at the weld, stick some photographic film on the other side, then run off and open the little door by remote control. The source is looking at the weld and is sending out x-rays (because of the decay of the cobalt60) which passes through the weld and the photographic plate is exposed. We then shut the door and develop the film. One weld x-ray finished. The advantage of this is that we don't have to drag an x-ray machine out there and then try to find a place to plug it in. Big advantage. Oh, as an aside, cobalt is sometimes alloyed into steel to harden it. Cobalt hardened steel could be used in, say, valve seats. But we don't use cobalt hardened steel for valve seats in nuclear plant primary systems. Guess why! Now you're an expert. Be sure to check that your name is spelled correctly on the role sheet and sign it so you can get credit for the class.
If you have a salt water slug what do you feed it?
Other salt water slugs.... They are cannibals
When you add salt to a slug why is it potentially deadly to the slug?
It's all caused by the principle of osmosis. Osmosis says that the concentration of minerals inside and outside of a membrane must be the same. When a watery slug cell comes into contact with pure salt, water seeps out of it to dilute the salt to the same concentration as in the cell, thereby draining all the cells and killing the slug.
How does a slug protect its self?
Who wants to eat a "SLIMY" slug.
How is salt an effective means to control slugs?
Putting salt on a slug completely dehydrates and kills the slug
How is putting salt on a slug chemical energy?
[1] Water always moves from areas of lower salt concentration to areas of higher salt concentration. [2] In a way, it's like the chemical process of transpiration in a plant. Water's pulled up from the roots, in liquid form. It passes out, in vaporized form, through openings ka stomata in leaves. [3] It's the same with slugs. The liquid in their bodies crosses out into the higher salt concentrations in the air and on the dehydrating slug's body, as water vapor.
What happens when you put salt on a frog?
If you put salt on a frog or any other kind of water dwelling creature....... IT WILL SHRIVEL UP AND DIE! If you give a little time of course.......
Why do slugs die when you put salt on them osmosis?
The salt leaches the fluids out of the slug, due to osmosis. The slug then dies of dehydration.
Why is it that salt can kill slugs when sprinkled on them but will make alive a dead fly when sprinkled upon one?
Salt cannot bring a fly back to life, it kills slugs because salt absorbs the water and dries them up. Salt cannot bring a fly back to life. It can revive it from a sleep which naturally occurs when the fly is faced with overwhelming pain though. Salt has certain properties which makes it draw moisture from things around it. As a slug has a very high percentage of water in its body, it is easy for salt to draw the water from the slug, causing its osmolarity rate to slow and it will become severly dehydrated and shrivel up, a waterless shell.
How do you feed a slug?
put the food ( mostly any fruit, vegtable, and dandelions) in the slug's cage and the slug will approach it and eat it.
What happens when the Paramecium gets close to the salt?
The water outside the paramecium has a higher salt concentration than the inside of the paramecium. Therefore, due to osmosis, the water inside the paramecium will move to the outside and dry out. It's the same thing happens when you put salt on a slug.
Why do slugs shrivel up when you put salt on them?
As with most non-ocean living animal and plant cells, salt applied externally creates a situation where the concentration of salt outside the cells is greater than that inside. Ions move into the cells and water then moves out to try and balance the difference to create an equalibrium. This loss of water within the cells causes them to shrivel up and die, furthermore causing the slug to die as well due to the lack of water.
How do you get a slug off your skin?
put salt on it
