DNA isolated from water samples collected in six different sites was prepared and analyzed by gel electrophoresis for the presen

ce of carp. The resulting gel is shown. Lanes 1 through 6 contain the DNA from each site. Lanes 7 and 8 represent the negative and positive controls.
Based on the banding patterns, how many sites tested positive for carp?

If lane 7 represent the negative control and 8 shows the positive controls (as we may infer by reading that lanes 7 and 8 represent negative and positive controls RESPECTIVELY) then we can say that lanes 1,3,5,6 and 8 tested positive for carp.

Gel electrophoresis can be defined as the process of separation of the macro-molecules  and the fragments based on their charge and size. In the gel electrophoresis given, the lane 7 indicates the negative control, and the lane 8 indicates the positive control. The bands formed in the lanes 1,3,5, and 6 corresponds to the ban in the lane 8, which is a positive control. Hence, based on these observations, it can be said that a total of 4 sites tested positive for carp.

Discuss crop intensification and how you would improve on it
algol13

Answer:

Crop intensification can be defined as the methodologies/procedures used to increase crop productivity (i.e., food, biofuel, fiber) in the same unit of land. These methods include relay intercropping, successions crops and the use of organic materials in order to increase the fertility of the soils (and therefore plant growth)

Explanation:

Crop intensification refers to the techniques used by farmers around the world aimed at increasing crop productivity (for example, wheat yield, cotton fiber production, etc.) These systems of crop intensification mainly include relay intercropping and successions crops, which increase the fertility of the soils (especially after oilseed crops) and crop resilience to climate change. The addition of organic material may also result useful to increase the plant growth (i.e., crop production) and agricultural sustainability by minimizing available resources such as, for example, water availability, chemical fertilizers, etc.

What is the overall charge of an atom? Why does it have this charge?
Ainat [17]
The overall charge of an atom is neutral because it has the same amount of protons and neutrons. They are positive and negative so they cancel each other out.
