During stress situations the sympathetic nervous system is more activated, causing a response of either run or fight. Because of that, the body needs to be prepared and there will be elevated blood pressure (the blood is going more to the skeletal muscle, heart,etc), dilated pupils (for better peripheral vision) and increased respiration. </span>
Norma is denied a promotion because she is at risk of developing cancer.
Normally, the concentration of solutes in our brain cells would be the same as the concentration of the cerebrospinal fluid. Thus, they form an isotonic solution.
Answer:
Ok so an updated overview of what has been learned regarding abiotic effects on different entomopathogen groups during the past 30 years. It focuses on entomopathogens that have emonstrated potential roles in microbial control. Abiotic environmental factors have diverse effects on entomopathogen survival, efficacy, and dispersal in the ecosystem. Extreme temperatures, desiccation, and UV radiation have the most detrimental effects on pathogen survival despite the existence of durable resting stages for most groups. Few field studies have investigated the influence of temperature on the severity and rate of transmission of viral disease. Since low temperatures do not affect the lethality of most baculoviruses, these viruses could be applied for area-wide management to reduce pest populations early or before the start of the growing season, as demonstrated against Helicoverpa zea and Heliothis virescens.
Pathogens of invertebrates, along with their hosts, inhabit all niches throughout the world, in ecosystems ranging from sub‐arctic to arid, temperate, and tropical. The abiotic factors that affect pathogen survival, reproduction, distribution and pathogenic effects on hosts consist of environmental elements such as temperature, moisture, and ultraviolet (UV) radiation, habitat characteristics including soil texture, soil type, and pH, as well as chemical inputs such as fertilizers, pesticides, and pollutants. In the present chapter, we will provide an updated overview of what has been learned regardingabiotic effects on different entomopathogen groups during the past 30 years. We focus our discussion on entomopathogens that have demonstrated potential roles in microbial control. The abiotic factors discussed complement other influences (biological and genetic, which are described in other chapters) that dictate the prevalence and activity of pathogenic organisms.
Hi
Basically, <span>Eukaryotic cells are a fair bit larger than Prokaryotic cells. Of course, if you look at them under the microscope, you can generally see details inside Eukaryotic cells, whereas Prokaryotes are just tiny dots. So, an exact measure doesn't exist, but the first are bigger than the second. </span>
