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.
The nurse should look out for symptoms such as extreme tiredness /severe dizziness, very low heart rate, trouble breathing, and swollen toes and finger (could turn blue also). This should show that the patient is developing a severe allergic reaction to the drug that could lead to heart failure.
Answer:
- Land management
- Resource depletion
- Climate change
- Political issues
Explanation:
There are many challenges for agriscientist. Some of them are listed above. Here is the brief explanation:
Land management would be an issue because the human's population would be increased if not managed well. Therefore, we would need more land to provide them shelter. However, we know that growth follows geomatric pattern and fertile land would not be much available for crops cultivation.
Resource depletion is another challenge for agriscientists. We are utilizing our resources very fast to grow crops and increase yield. For example, groundwater is being pumped at very fast rate in many places/countries where surface water is limited. Similar is the case with other resources. We need to use our resources in a sustainable manner so that our future generations would not have to suffer.
Continous changing in cliamte is also a potential threat to modern generations for almost everything including agricture. As the temperature is rising, the crops would not be able to thrive harsh environmental conditions. Therefore, a major challenge would be to produce crops that can survive in hot temperatures.
We know that agri-industry is a multi-billion industry that is heavily driven by consumer habbits. Therefore, governments acts between consumer and industry, sometimes in positive ways but sometimes in negatives ways too. Therefore, it is also a challenge to have best policy which is not in favor of either group alone.
Answer:
Factors that effect the earth climate are given below.
1) Concentration of greenhouse gases.
2) Intensity of sunlight.
3) Concentration of carbondioxide. in the atmosphere.
4) Tilting of the earth.
Explanation: If the concentration of greenhouse gases increases, the climate becomes hotter because greenhouse gases trap the reflected sunlight. If the intensity of sunlight is low, the climate is cold while the intensity of sunlight is high, the climate is hot. Climate is changed due to tilting of earth. Carbondioxide emissions also causes increase in temperature.
