Since he obviously helped with the improvement of the microscope, his higher lens quality helped him see a single cell organism. Well, if a single cell organism exists, spontaneous generation is corrupt. He really just proved what Zacharias Jensen did.

If researchers genetically modify pigs to produce human antigens on their cell surfaces how can this improve the chances of a human body not rejecting such transplant?
A human would not reject transplant of pigs cells with a human antegen so the chances would be 100% of non rejection if the right human antegin was placed
What animal and human organs can be transplanted to humans?
Human to Human (allotransplantation):Transplantable organs include: heart, liver, kidneys, lungs, pancreas, and thymus.Transplantable tissues include: Bone, skin, corneas, heart valves, intestines, veins, and tendons.Animal to Human(xenotransplantation):Insulin-producing pig cells, wrapped in seaweed to avoid immune attack, have been tested on human diabetics in Russia.The results were encouraging, and the procedure is approved for sale in Russia. However, it will probably be some time before other countries approve this, or any xenograft procedures.Dangers of xenotransplantation:Heightened risk of rejection of organs, tissues, and cells, and vascular rejection.Significant risks of disease, especially of retro (ancient) viruses, to the recipients.Religious objections.Ethical issues: risk of genetic alteration of the animal organs and tissues.
How old should a miniature schnauzer be to stud out?
Studding ANY dog should be a very careful choice.People have a misconception that any 2 dogs can make ''great puppies''.The truth is, many dogs carry hidden flaws in their genes that can,when mixed with dogs that may have the same hidden flaws or mutation cause major health and temperment issues. Im not going to get into breeding 'ethics', as this is an age question. The best age to stud/breed a male mini schnauser sized dog is 16 to 18 MONTHS.The testicles of this sized breed,are fully functional at 8 months of age.Though conception of a female in season can be under 5 months of age,if she is bred to a very virile male or an 'early bloomer'. Younger dogs at like 5-8 months of age, have less mature spermatozoa than older males,say 16 moths old.Mature sperm make better puppies.Underdeveloped sperm have a hard time reaching and fertilizing the eggs,and are not fully able to replicate the DNA within them,as well as the mature sperm. Also mental maturity at under a year is still developing.An older male,might ''catch on'' quicker than a 5 month old.Some females won't tolerate being a learner bitch,and become frustrated. This can result in ''rejection'' of the male.These rejections can end up in a physical altercation.Males exposed to testosterone,have higher mating drives,that asist in proper copulation.Please note that a bitch can and will attack a male when she is not ready to receive him (bitch will only receive a male in full 'standing' heat). I hope this helps you out.

How did zacharias jansens inventions and ideas help lead to the rejection of spontaneous generation?
His invention helped the rejection od spontaneous generation because no one new who he was so no one pay attention to him
How did the compound microscope invented by Zacharias Janssen lead to the rejection of spontaneous generation?
Because it helped with the cell theory.
Why has spontaneous generation been called a mistaken idea by the scientific community?
Spontaneous generation was called a mistaken idea by the scientific community because it was based on incorrect assumptions about the origins of living organisms. The discovery of microorganisms and advancements in microbiology showed that living organisms do not arise from non-living matter spontaneously. This led to the rejection of spontaneous generation as a scientific explanation for the origins of life.

What is the load rejection and load pick-up in the power generation?
Load rejection occurs when load is suddenly removed from the generator. The most obvious example of this is the breaker connecting the generator to the power grid opens. This results in a full load rejection. Load pick up means the generator is supplying power to a given load. When a generator comes on line, it will pick up some load that might have been supplied by another generator.
Why was the theory of spontaneous generation rejected?
Lazzaro Spallanzani, an Italian scientist, constructed an experiment by placing broth in two separate bottles, boiling the broth in both bottles, then sealing one bottle and leaving the other open. Days later, the unsealed bottle was teeming with small living things that he could observe with the newly invented microscope. The sealed bottle showed no signs of life. This excluded spontaneous generation as a viable theory, because if it was true, then there would be life in both bottles.

What is Kerouac's response to Podhoretz's criticism of the Beat Generation?
Kerouac responded by dismissing Podhoretz's criticism as a misunderstanding of Beat philosophy and lifestyle. He argued that the Beat Generation's rejection of mainstream values was a conscious choice to live authentically and explore alternative forms of expression. Kerouac believed that Podhoretz's critique missed the underlying messages of creativity and rebellion that the Beat Generation sought to convey.
