Answer:
d. All of the above
Explanation:
A scale can be defined as an ordered numerical or alphabetical sequence that is typically used for taking measurements such as size, weight, height, length, etc. Also, a scale is used in the field of science to assign magnitude to physical activities and natural phenomenons such as an earthquake using the Richter scale. 
In Science, there are four (4) main scales of measurement and these includes;
1. Interval scale: data can be arranged in an ordering scheme and subtracting its differences is meaningful. Examples are year, temperature, time etc.
2. Ratio scale: data can be arranged in an ordering scheme and subtracting its differences is meaningful with respect to the value of true zero. Examples are height, price, weight, distance etc.
3. Ordinal scale: data can be arranged in an ordering scheme but subtracting its differences is meaningless or impossible. Examples are happy, sad etc.
4. Nominal scale: it is characterized by data that are non-numerical, comprises of categories, labels or names and can't be arranged in an ordering scheme.
<em>Hence, scales can represent;</em>
<em>a. A range of information. </em>
<em>b. A range of resources. </em>
<em>c. Proportional measurement. </em>
 
        
                    
             
        
        
        
Answer:
Crops are now immune to many diseases and insects.
Explanation:
The constant advancement of science and technology within agriculture has been very beneficial to the better use of crops and to stimulate a better food supply, which has a beneficial impact not only on the lives of consumers, but also on the economy. One of the greatest benefits presented by this advance in science and technology is the ability to give agricultural crops resistance to pests and diseases. This is possible thanks to genetic engineering and advances in the study of agricultural entomology and microbiology, which have allowed scientists to manipulate plants to resist attack by harmful insects and microorganisms in agriculture. This resistance allows the plants to develop well and to produce products suitable for sale.
