The trp and lac operons are regulated in various ways. how do bacteria regulate transcription of these operons? sort the stateme
Elza [17]
I found the exercise on the internet. Attached is a picture of the <span>statements and the bins.

Operon is not transcribed:
-trp operon: tryptophan present (tryptophan works as an inhibitor of the operon)
-lac operon: lactose absent (lactose works as the trigger for the operon)

Operon is transcribed but not sped up by positive control:
-trp operon: tryptophan absent </span>(tryptophan works as an inhibitor of the operon, when absent the operon is active)
-lac operon: lactose present, glucose present (lactose works as the trigger for the operon, but when glucose is present, the operon activity remains only at basal level)<span>

Operon is transcribed quickly by positive control:
-lac operon: lactose present, glucose absent </span>(lactose works as the trigger for the operon, but when glucose is absent, the operon activity is at its maximum activity)

Hot springs in Yellowstone National Park can reach 205 degrees Fahrenheit (96 degrees Celsius), a temperature at which few organ
Verdich [7]

Answer:

Thermophiles have heat-resistant enzymes.

Explanation:

A hypothesis refers to the possible explanation of processes and is based on observation.  

Thermophiles are able to survive the extremes of the temperature found in hot springs of Yellowstone National Park. Their ability to withstand such temperature may be due to the presence of heat resistant enzymes.

Since enzymes are proteins, they are denatured at higher temperatures. It is one of the factors that determine the temperature range that can be tolerated by an organism.  

Hence, the presence of heat resistant enzymes in thermophiles can be one of the possible explanations about their ability to survive under the temperature as high as 205 degrees Fahrenheit.

There are other names which refer to as accretion. For example, Accretion geology is termed as the increase in the size of a tectonic plate by addition of materials which convergent boundary.
Accretion atmosphere is termed as the process by which water vapor which is in clouds forms water droplets around nucleation sites.

kykrilka [37]

Living in a tropical environment where one learns to orient oneself through a vertical landscape of tall trees and speckled light is part of spatial orientation.

<h3>What is the rain forest zone?</h3>

The tropical rain forest zone is the zone that is known to have a very high amount of rainfall for most of the year. The rain forest zone often has a lot of luxuriant trees that blossom all year round and serve as a breeding ground for many insects such as mosquitoes.

Most of the trees in the tropical rain forest zone are arranged in strata where the tallest trees often form a sort of canopy in the area thereby reducing the light that gets to the pants that are found below and keeping the area cool.

Hence, living in a tropical environment where one learns to orient oneself through a vertical landscape of tall trees and speckled light is part of spatial orientation.
