Biological pest control methods supplement but cannot replace chemical pest control methods.t/f

Answers

This is false. Farmers of organic food have been doing this for a whileand it has become a trend. Food grown this way is usually a lot moreexpensive but the evidence that the food made in this manner ishealthier still up for debate as inconclusive results have been found,pointing out that there's really not that much of a difference.

How does targeted cancer therapies differ from traditional chemotherapies

Answers

Chemotherapy tends to kill all cells, including healthy ones, in order to eradicate malignant cancer. Targeted cancer therapies aim to solely eradicate the cancerous cells in the affected region.

Answer:

Chemotherapy drugs destroy cells that grow and divide rapidly. However, in addition to the cancer cells that replicate rapidly, they also kill normal, healthy body cells in the hair and skin causing significant side effects. Targeted therapies are an advancement in medicinal chemistry because they specifically target cancer cells, which will reduce damage to healthy cells. Also, some targeted therapies may be less toxic on the body overall, even though side effects still occur.

Behavioral cycles that repeat daily are called ____ rhythms

Answers

Behavioral cycles that repeat daily are called circadian rhythms.

Circadian rhythms are behavioral, physical and mental changes that occur in living organisms (plants, animals, fungi and cyanobacteria) and follow a 24hours (daily) cycle. Circadian rhythms regulate many physiological processes and they are influenced by external cues such as sunlight and temperature. They determine when to sleep, when to eat or whether an individual feels wide-awake, or feels tired at different times of the day.
