Answer: an area where all draining water goes into the same river system

Explanation:

A watershed is an area which occupies water from the rainfall and snow melt that drains into a water body such as marshes, river , streams and groundwater. This is also called as drainage basin because of the fact that the water from many sources drains into a common outlet.

On the basis of the above description, this can be said that a watershed is an area where all draining water goes into the same river system is the correct option.

slavikrds [6]

Answer:

Sonic Hedgehog.

Explanation:

Sonic hedgehog is a secreted protein that in humans is encoded by the SHH gene. It is the best studied ligand of the hedgehog signaling pathway, others being desert hedgehog (DHH) and Indian hedgehog (IHH). It plays a key role in the development of animals, from insects to mammals. In vertebrates, it is involved in organogenesis, including the growth of digits on limbs and the organization of the brain.

Sonic hedgehog has also been shown to act as an axonal guidance cue. It has been demonstrated that SHH attracts commissural axons at the ventral midline of the developing spinal cord. Specifically, SHH attracts retinal ganglion cell (RGC) axons at low concentrations and repels them at higher concentrations

Many marine organisms depend on up welling to bring nutrients to the surface. How might El Nino affect a fisherman's way of life
svp [43]
During an El Nino, warm water gathers along the West coast of South America, so the nutrient rich water is no longer being upwelled. keeping in mind that cold water sinks and warm water rises, usually the warm water near coastal regions would not be full of nutrients compared to the cold water where the nutrients fall. therefore, more fish will be located or migrate to areas of this nutrient rich cold water instead. So, many fishermen would not have high yields of fish ultimately affecting their way of life and money. also a lot of these fish that remain at the surface would not be as healthy or nutrient rich.

hope that helps! :))

What happens to contraction of a muscle cell if some of the Ca2+ that was released during a contraction is still in the cytoplas
Kazeer [188]
<h2>Muscle contraction in cytoplasm </h2>

Explanation:

  • Calcium stays in the sarcoplasmic reticulum until discharged by an improvement. Calcium at that point ties to troponin, causing the troponin to change shape and expel the tropomyosin from the coupling destinations. Cross-connect stick proceeds until the calcium particles and ATP are never again accessible.
  • ATP is basic to get ready myosin for official and to "revive" the myosin.
  • When the actin-restricting destinations are revealed, the high-vitality myosin head overcomes any issues, framing a cross-connect. When myosin ties to the actin, the Pi is discharged, and the myosin experiences a conformational change to a lower vitality state. As myosin consumes the vitality, it travels through the "power stroke," pulling the actin fiber toward the M-line.

using the process of bacterial transformtion, a student reseacher inserted a plasmid containing a gene for antibiotic resistance
Elena-2011 [213]

Transfer of newly created plasmids to e coli. The bacteria that contains a plasmid with antibiotic resistance will grow in the presence of antibiotic concludes that the insertion was successful.

<h3><u>Explanation:</u></h3>

The plasmid DNA that contains the foreign DNA when integrated with the competent bacteria which is e coli and heated,  plasmid DNA will be entering into the bacteria by means of some smaller pores that are created in the  membranes of the cell.

The plasmid DNA will be copied many times with the help of the replicating mechanism of DNA of the bacteria. Bacteria will grow on a nutrient rich food called agar after the transformation process. Those bacteria that contains a plasmid containing antibiotic resistance only grow in the antibiotic presence. Transformed bacteria will then grow in larger quantity.
