Answer:
The phenotypic variation for the trait is continuous
Explanation:
Genetically speaking, quantitative traits are controlled by many genes, classes are not easily distinguishable and there is a continuous distribution of the phenotype. These characteristics refer to measurements of quantities (weights, volumes, measurements: kg, m, cm, g, m2, etc.).
In other words, quantitative characteristics are those that exhibit continuous variations and are partly of non-genetic origin; that is, they are greatly affected by the environment.
Answer:
hello i think b not completely sure
Explanation:
1. The strength of magnetic field at A is 64 unit, then the magnetic field strength at B. is 256 units.
64 × 64 = 256 units.
2. If the strength of magnetic field B is 6 units then the strength magnetic field at A is 24 units.
which is 256 : 4 = 16 units.
Magnetic field is one of the two ways where the intensity of magnetic field is being expressed.
An example of a population in which evolution could take place in a relatively short period of time could be pathogenic bacteria exposed to antibiotics.
Answer: Option A
<u>Explanation:</u>
Evolution if takes place within a short period of time say the next generation that is called as micro evolution. This is caused when a specific organism exposed in a different environment at once modifies its genes to suit the new environment. This phenomenon can be very well seen in the pathogenic bacteria which are exposed to antibiotics.
When an antibiotic is prescribed to bacteria initially it nullifies its effect by destroying it. When continuously exposed to a certain antibiotic some bacteria dies but there are few which becomes resistant to it and survives. This on the other hand multiplies producing a generation that can’t be touched by the antibiotic.
Sometimes you mix different substances and you don't make new substances but mostly of the time you do make new substances , so the answer is chemical change.
