Heat lamps are designed to reheat food when it falls below 135 f true or false
iren2701 [21]

The given statement is false, as the heat lamps are not created to reheat food when food falls under 135 degrees.  

A heat lamp refers to an incandescent light bulb, which is utilized for the primary objective of producing heat. The heat lamps are not considered for holding the probable venturous foods hot at a minimum of 135 degrees Fahrenheit. In order to heat up a probable venturous food for decent holding, the food should be cooked over swiftly to a least internal temperature of 165 degrees.

Ecosystems with greater biodiversity have an increased stability.
IRINA_888 [86]
Yes, this is correct!

Let's imagine two systems, one with 50 species and one with 4000. Both of them experience a draught and as a result 25 species of the first one die (that's quite likely) and 800 of the second population die out (more would not be very likely).
So the first one lost 50% of species and the second one 20% - that means that the second one, with greater biodiversity has a bigger stability:)
