Why do bacteria have to grow before reproduction?

Most bacteria rely on binary fission for propagation. Conceptually this is a simple process; a cell just needs to grow to twice its starting size and then split in two. But, to remain viable and competitive, a bacterium must divide at the right time, in the right place, and must provide each offspring with a complete copy of its essential genetic material. Bacterial cell division is studied in many research laboratories throughout the world. These investigations are uncovering the genetic mechanisms that regulate and drive bacterial cell division. Understanding the mechanics of this process is of great interest because it may allow for the design of new chemicals or novel antibiotics that specifically target and interfere with cell division in bacteria.

Why are fungal insecticides an attractive alternative to chemical pesticides for growing food crops?
boyakko [2]

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.

Nearly all organisms on earth carry out some form of glycolysis. How does that fact support or not support the assertion that gl
Blizzard [7]
Glycolysis is the breakdown of metabolic materials into energy and pyruvic acid. it is supported by me because without energy we wouldn't be able to do anything and almost every thing we do requires energy from taking a walk down to the pumping of blood by the heart throughout the body

Explain how animal like plant like are similar and different
Delvig [45]

Answer: The main way animal-like protists differ from plant-like protists is in the way they get energy. Animal-like protists are heterotrophs. ... Plant-like protists, on the other hand, are autotrophs. They can make their own energy from the sun or other sources just as plants can.
