Answer: Cell number one is an hypotonic solution, cell number two is an isotonic solution, and cell three is an hypertonic solution.
Explanation:
Cell number one which is a 98% water content is added the 100% water solution, water moves from low to high concentration. Therefore, the water moves from the solution into the cell, which is hypotonic.
Cell number two which is a 98% water content added with a 98% water solution. These two solutions are equal to one another, so the water does not move. This is isotonic.
Cell number three which is a 98% water content added with a 80% water solution. Water moves from high to low concentrations, so water moves from the cell to the solution. The water leaves the cell, which is an hypertonic.
Answer:
Platelets would release signals to stimulate the production of more platelets
Explanation:
Positive feedback mechanism is one of the two types of feedback mechanisms (other being negative feedback mechanism) in which the products of a process stimulates more of that product to be synthesized or produced. In other words, the result of a reaction increases the secretion of more results.
In this case where the injured tissue of a cut initially releases chemical signals into the bloodstream. These chemicals signal platelets to be attracted to the injured area. However, if this is a positive feedback mechanism as explained above, Platelets would release signals to stimulate the production of more platelets.
Answer:
a. lack of running water
Explanation:
The Tippy tap technology was invented to solve the issue of running water problem. This technology is designed mainly for hand washing and it is used in the rural area to solve the running water problem.
This technology technique needs only forty milliliters of water; it is less expensive and reduces the chance of transmitting diseases as the user only touches a bar of soap suspended by a string.
Preserves animal tracks are called trace.
