Answer:
Fungal insecticides are an attractive alternative to chemical pesticides for growing food crops because fungal insecticides can eliminate both harmful insects and plant pathogen while chemical pesticides can only kill insects.
Explanation:
As it gets harder to get approval for novel synthetics and existing synthetic pesticides are pulled from shelves, biopesticides become more attractive.And then there's the rise of weeds and microbes resistant to traditional pesticides. Many commonly used chemical pesticides are facing pressure today due to overuse, improper use, and long-term use.Some biopesticides repel pests, while others disrupt mating or cause a specific disease to strike invaders that would nibble on delicate fruits and vegetables.That's especially true when compared with synthetic pesticides, which often contain toxic chemicals such as arsenic, chlorine, ammonia and formaldehyde. Some synthetic pesticides have been shown to have harmful effects on the environment and human health. One family of pesticides, called neonicotinoids, is being blamed for the decline in bee populations over the last decade. Trichoderma, a versatile mold, is also commonly used. Some release enzymes that dissolve potential pathogens; others form barriers around plant roots and make it impossible for harmful bacteria and pathogens to pass through.
Another fungus — Metarhizium, or the green muscardine fungus — is frequently used in the field, shielding crops from beetle grubs, wireworm, corn root worms and countless other insects. One variant is now being used to develop biopesticides — including a line by MycoPesticide — that can cause a mushroom to grow from a pest's dead body to distribute spores that warn other insects.
Answer:
At the base of Actinopterygii
*This is a unique characteristic of this group.
Explanation:
A peculiar characteristic organ observed in ray-finned fish (as well as in Sarcopterygii, or lobe-finned fish) but not in cartilaginous fish like shark is the swim bladder.
This organ is often described to be a sac containing gas. It helps these set of fish adjust its buoyancy and its position in the water by regulating the concentration of gas present in it.
The swim bladder is formed as a pouch coming off the embryonic digestive tract, and in chondrosteans and holosteans, with a set of teleosts e.g. the eels, it maintains an open pathway to the esophagus. In majority of the bony fish, the swim bladder is totally sealed off, as gas levels in their swim bladder are regulated by producing gas into the bladder via a network of capillaries, the rete mirabile (Latin word for "marvelous net").
The swim bladder is homologous to the lungs of tetrapods. Since they are formed in the same vein. Few fishes that have an open swim bladder employs it as a breathing organ.
Para poder probar que la generacion espontanea despues de hervir el agua no es posible ya que en ese tiempo esa era la teoria aceptada por todos.
Anteriormente alguien habia hecho el mismo experimento tapando el frasco con un corcho, ese experimento despues de ser hervida el agua produjo seres nuevos (microorganismo) y Pasteur hirvio el agua solo para provar que los microorganismo no se podian generar magicamente despues de ser hervidos
An invertebrate, because an animal with a vertebrate is an animal with a backbone.
