What is allelopathy?
Allelopathy is the inhibition of growth of a plant due to biomolecules released by another. It is the opposite of symbiotic mutualism. The biomolecules are called allelochemicals and are produced by some plants as secondary metabolites
The size of a cell is limited by it's?
The maximum size of a cell is limited by its need for enough surface area in order to conduct exchanges with its environment. This is referred to as contact inhibition.
How does a emperor penguin's digestive system works?
Long-term preservation of stomach contents in incubating KingPenguins-- Male King Penguins (Aptenodytes patagonicus) are able tostore undigested food in their stomach for up to 3 weeks during theirincubation fast. Such an adaptation ensures hatchling survival if theirmate's return is delayed. Using small electronic recorders, Thouzeau et al.(2004) studied the change in gastric pH, motility and temperature duringthe first week of food storage. The pH could be maintained at values ashigh as 6 throughout the incubation fast, a pH unfavorable for aviangastric proteinase activity. Gastric motility was markedly reduced for mostof the incubating birds, with lower motility probably associated with abetter conservation of stomach content. Stomach temperature wasmaintained at around 38°C. The fact that stomach temperature ofincubating birds did not show a daily rhythmic fluctuation as seen in nonbreedingbirds could be due to temperature constraints on embryodevelopment. Thus, this study demonstrates substantial adjustments of pHand gastric motility in incubating King Penguins, which may contribute tothe inhibition of digestive gastric processes. Mechanisms underlying theseadjustments are probably complex, including a combination of neuronal,humoral, and/or hormonal factors.
How do you stop other dogs that are off the lead from attacking your dog?
It is a common misconception that getting your dog spayed or neutered will stop it from humping. Some vets will tell clients that while trying to persuade them to get the operation done. While it is important to get your pet spayed or neutered, it is not a fix to the "humping dilemma." Dogs only hump sexually when they mount a female that is in heat. Other than that it is a dominance issue. It is almost purely a way to establish pack order. A dog that has dominance issues may also start to become aggressive. It is something that needs to be dealt with, and not put off as an annoying habit.Some basic starter tips:If you let the dog on the furniture, stop. This makes them think they are higher up in the pack. The same goes for allowing them to sleep on your bed.Make sure the dog knows that you are the owner, and you are in charge. Do daily training exercises with them. Make it an enjoyable time, but be firm. When they do well, slip them a small treat. When they do not, do not acknowledge it. Use their name. Fido, sit.Do not allow him to push through a door before you. He needs to learn to sit and stay until you allow him to go.If the dog eats in the house, make sure he is not fed until after you eat. In a pack, alpha dogs always eat first.There are other things you can do as well. These are just the ground rules. This well help establish pack order in your home. It may seem odd, but they are dogs, so they think like dogs. You need to relate to them in the same manner.
Can dogs show affection by gentle biting?
Usually between other dogs, if the biter has nipped the bitee's muzzle while its ears are lowered and/or it's tail is down and wagging; it is called muzzling and is a submissive response developed in puppies. Muzzling is a sign to more dominate members of the dog's selected 'pack' that the dog has no intention of challenging their dominance.Biting between puppies is play behavior, which helps 3 separate behaviors. The first teaches the puppies bite inhibition as litter mates will often yelp if bitten too hard, usually causing the parents to repremand the culprit biter. The second helps hone the puppies 'hunting instincts'. Puppies will often crouch and pounce on their litter mates, perfecting tactics that they would have been otherwise used in the wild. The last is not really a behavior, but instead play helps the pups create a dominance heirarchy among litter mates and pack members.Both muzzling and the play bite origionate from the dogs wild ancestors, the wolf. Muzzling origionates from the fact that adult wolves would return to the pack with meat in their stomachs, the puppies would nip and lick at the adult wolfs muzzle in an attempt to get the adult to reguritate some of its meal. (It's gross, I know. But wolves can't carry large amounts of food back to their dens without eating it first, or else the pups would get attacked by other predators looking for an easy meal.)Since even children from 6 and older are taller than most dog breeds; dogs will both muzzle and play bite at either a person's hands, or they will jump up on people in an attempt to get to her/his face.Even though muzzling and play biting are not aggressive behaviors, it is best to teach the dog bite inhibition at an early age before the dog's bite force becomes stronger as it grows. The easiest way to do this is to let out a high pitched yelp as soon as you feel the dogs/puppies teeth on your skin, then pull your hand away and do not pay any attention to the dog/puppy.The yelp and pull technique is usually enough of a deterrant to get any dog to stop biting you, but if not then drop a handfull of pennies into an empty soda can and tape the mouth shut. The rattle of the pennies against the soda can is a very aversive sound to any dog/puppy, which will make them release you in the confusion.Forgive me if this was an extensive response, but 'gentle biting' can mean a number of things. I just gave the 2 most common forms of biting that people have when they have a dog. I hope that it was of some assistance to you.
Increasing the substrate concentration in an enzymatic reaction could overcome what?
competitive inhibition
What is the Inhibition of the bone marrow?
Myelosuppression is inhibition of the bone marrow.
How is competitive inhibition different from competitive inhibition?
Competitive Inhibition is a substance that binds to the active site in place of the substance while Non-competitive Inhibition is a substance that binds to a location remote from the active site. (:
How is competitive inhibition different from non competitive inhibition?
Competitive Inhibition is a substance that binds to the active site in place of the substance while Non-competitive Inhibition is a substance that binds to a location remote from the active site. (:
How can you determine whether the zone of inhibition is due to death of a bacterium or to inhibition of growth?
How can you determine whether the zone of inhibition is due to death or the effect of the antibiotics?
What happens when a protein is inhibited?
When a enzyme is inhibited (many proteins are enzymes), it just means that the enzyme will be reduced in its ability to catalyze a reaction. There are a few types of Inhibition like Competitive Inhibition, Noncompetitive Inhibition, and Irreversible Inhibition.
What are the ratings and certificates for Inhibition - 1976?
Inhibition - 1976 is rated/received certificates of: USA:R
What causes immune inhibition?
overexposure to heat and uv radiations causes for the immune inhibition.
How do you calculate percent inhibition?
% inhibition = [(normal activity - inhibited activity) / (normal activity)] * 100%
What was Excitation and Inhibition about?
Excitation and Inhibition occur in the neurons. Excitation is when a neuron becomes depolarized and fires an action potential. Inhibition is when a neuron becomes hyperpolarized preventing it from firing an action potential.
The process by which the product of a system shuts down the system or limits its operation is called the inhibition?
feedback inhibition
Make a sentence with the word inhibition?
Raised glucose levels appear to be due to inhibition of insulin secretion.
