The oral ld50 value for cypermethrin is 247 mgkg compared to 5000 mgkg for hexaflumuron therefore what is the more toxic of these two pesticide?

Cypermethrin, assuming the LD50s for the two chemicals are for the same period of time. LD50 is the lethal concentration where half of the individuals die in a given time period. Higher numbers mean that is takes more of the chemical to kill organisms, whereas lower numbers mean it takes less of the chemical to kill organisms. LD50s depend on what animal was used in the experiment.

What is the difference between alpha cypermethrin and technical cypermethrin?
Alpha cypermethrin is a specific form of cypermethrin that contains only the active ingredient alpha-cypermethrin, while technical cypermethrin is a mixture of different forms of cypermethrin along with impurities. Alpha cypermethrin is typically more concentrated and potent in terms of insecticidal activity compared to technical cypermethrin.
Hyper means what in hypertonic?
In the term "hypertonic," "hyper" means increased or higher. Therefore, hypertonic solutions have a higher concentration of solutes compared to the concentration of solutes in the environment or compared to another solution.
What makes the waterevaporate?
Water has a large vapor pressure compared to air. Water molecules therefore readily move into the air.
Why do not we skiers sink in the fresh snow?
We do not sink because the skis have a high surface area compared to our feet, therefore we would float on fresh snow.
What is similar about calcium chloride and calcium chlorine?
There isn't an existing compound as calcium chlorine, therefore it cannot be compared with calcium chloride which is a naturally occuring salt.

How much pesticide will each take in compared to each grasshopper?
There is no testing that has been done recording the amount of pesticide a mouse will take to kill compared to a grasshopper. The amount of pesticide that it would take would depend on the size of the grasshopper, and the size of the mouse.
How much pesticide will each snake take compared to each grasshopper?

How much pesticide will each mouse take in compared to a grasshopper?
The mice ingested 10x the amount of pesticide since 10% of what the grasshopper consumed is passed on to the next trophic level, and since about 1 mice eats 10 grasshoppers, that's 100% of the pesticide ingested by the mice.
Which part of the word insecticide must mean killer?
When compared to such words as fratricide, homocide, genocide, pesticide and herbicide (all of which have to do with killing) you can see that it's the -cide part.
How are the levels of pesticides measured?
Pesticide levels are typically measured using analytical techniques such as gas chromatography or liquid chromatography coupled with mass spectrometry. These techniques can detect and quantify the presence of specific pesticide residues in a sample. Measurements are then compared to safety standards and regulations to determine if levels are within acceptable limits.
How much pesticide will each mice take compared to each grasshopper?
Theoretically the same percentage in relation to it's body weight, but poison labelled for rodents and insects are different things
Why plants lesser energy requirement compared with animals?
Plants have lesser systems compared to animals. Therefore, energy "divisors" are lesser.
Compared to gamma rays x-rays have?
Lower frequency, therefore lower energies.
What is the antonym for relatively?
"Relatively" means "as compared to other things". The antonym would therefore be "Absolutely".
Why cyclohexanol is neutral?
Cyclohexanol is neutral because it contains both acidic and basic functional groups, which cancel out each other's effects in terms of acidity and basicity. The hydroxyl group can act as a weak acid, but the ring structure stabilizes any resulting negative charge, making the molecule overall neutral.
Are ribosomes found on the RER?
Yes, ribosomes are found attached to the rough endoplasmic reticulum (RER). This association allows the RER to synthesize proteins destined for secretion or insertion into membranes.
