Issues and Needs in Science identified by the USGS as being connected to agricultural practices' environmental impacts are as follows:
- Effects of habitat fragmentation and changing land use on animals.
- Juggling competing water demands from the urban and agricultural sectors.
- Interactions between surface water, subsurface water, and air that have an impact on water quality.
- Water quality effects of irrigation, drainage, and return flow in agriculture.
- The creation and application of cutting-edge farming methods to preserve soil and water and enhance water quality.
- Genetically modified creatures' effects on naturally occurring species and environments.
- Rapid assessment methods and tools for locating agricultural contamination sources.
- Impacts of pesticides, fertilizers, and sediments on the habitat quality and health of fish and wildlife.
- Effects of soils, riparian forests, and wetlands—characteristics of watersheds—on nutrient uptake, retention, and cycling.
- Endocrine disruptive substances, veterinary medications, feed additives, hormones, and infections are transported across terrestrial and aquatic ecosystems and ultimately end up there.

Answer:
It is necessary because of the base pairing between the desired gene and plasmid
Explanation:
Restriction enzymes are enzymes that recognize the specific DNA sequence-restriction site, double-stranded cut DNA and produce ends with a single-stranded overhang. The overhangs of the plasmid can stick together with overhangs of gene of interest by complementary base pairing. Joining of ovarhangs is done by the enzyme DNA ligase.
Answer:One type of active transport is called the sodium-potassium pump which helps muscle cells contract.
Explanation:like if you dont have a sodium-potassium your bone wil have been weaker.
Answer:
It is positive. B/c nucleus consists of postively charged particles called Protons, and neutral charged (no charge) particles called neutrons. So it has a net positive charge.
Explanation:
The series explores strategies to sustainably feed more than 9 billion people by 2050. All pieces are based on research being conducted for the 2013-2014 World Resources Report. The world is projected to hold a whopping 9.6 billion people by 2050.
