The protein thorain is encoded by the gene thrL, and thorain is a negative regulator of the thrMN operon. Assume there is no oth

er regulation taking place. Predict the phenotype of a thrL- mutant that encodes a nonfunctional thrL protein.
a. The thrM and thrN genes would be transcribed at higher levels compared to non-mutant.
b. The thrM and thrN genes would be transcribed all lower levels compared to non-mutant.
c. The thrM and thrN genes would not be transcribed

Answer:

The correct answer is option a, that is, the thrM and thrN would be transcribed at high levels in comparison to non-mutant.

Explanation:

Based on the given information, in the existence of thorain the expression of thrM and thrN will be prevented as thorain functions as a negative regulator. In case, if the gene, which codes for thorain, that is, thrL gets mutated, the coding for the functional thorain would get prevented.  

With the encoding of the non-functional thrL protein, there would be an enhancement in the expression of thrN and thrM genes and it will get transcribed at higher levels in comparison to the non-mutant or the wild-type.

What are the three goals of integrated pest management (IPM)?
Delicious77 [7]

The correct answer is C. To reduce the use of artificial pesticides, reduce costs, and control pests.

Explanation

Integrated pest management (IPM) is a method that integrates different practices and scientific principles to make adequate management with pests. This method considers knowledge about the habits, life cycle, needs, and aversions of the pest, reducing the use of toxic methods and implementing less toxic methods, monitoring pest activity and adjusting methods over time, tolerating harmless pests, setting a threshold to decide when it is time to act, among others as its main principles. Therefore, the correct answer is C. To reduce the use of artificial pesticides, reduce costs, and control pests.

Anyone got the answers to the UNIT: UNDERSTANDING ORGANISMS test?
wariber [46]

The Unit 'Understanding organisms' is not found here, but an organism is a biological system composed of cells.

<h3>What is an organism?</h3>

An organism is a living entity that is defined by the presence of cells, which are the basic structural unit of life.

Organisms have the ability to respond to external stimuli, perform metabolic activities and exhibit a internal state of equilibrium (homeostasis).

Organisms can be composed of single cells (e.g., bacteria, protists) or many cells (e.g., plants and animals).

In conclusion, the Unit 'Understanding organisms' is not found here, but an organism is a biological system composed of cells.
