The blood cells likely placed in a "hypotonic solution".
<u>Option: A</u>
<u>Explanation:</u>
When human blood cells are immersed in a solution with a low concentration of solute than is present in cells, osmosis allows water to pass through the cells, allowing the cells to get swollen; such a fluid is hypotonic to the cells. But when held in a solution with a greater concentration of solute, osmosis allows water to pass out of the cell, the cell is smaller and crenated in form; then a solution is hypertonic to the cells.
Healthcare facilities preserve human blood cells in a plasma solution that has the proper salt and protein ratios. Such solution is formulated to be mildly hypertonic to the red cells, thus maintaining the integrity of the cells and avoiding hemolysis.
The mechanism that affected the gene pool of the immigrants that entered the United states Through Ellis Island is Gene flow.
Gene flow involves the movement of genes or alleles between interbreeding populations of a particular species. In other words it is the movement of genes from one population to another population. Actually it may be an important aspect of evolution; evolution can occur as a result of genes being transferred from one population to another. Gene flow occurs when there is migration, since the loss or addition of people can easily change pool frequencies even without no other evolutionary mechanisms operating.
Answer:
The correct answer is Broca's area or Wernicke's area.
Explanation:
Aphasia refers to a language disorder, which arises due to the destruction of the parts of the brain, which are accountable for language. Aphasia generally causes due to the destruction of Wernicke's area or Broca's area. For the majority of the individuals, these are the sections of the brain's left hemisphere.
The condition known as aphasia generally takes place suddenly, usually as the outcome of a head injury or stroke, however, it can also arise gradually, in the individuals suffering from a brain tumor. The disorder hampers both the comprehension and expression of language and at the same time the tendency to read and write.
Flatworms-In the life cycle of trematode flukes of the subclass Digenea, mollusks (mostly snails) serve as the intermediate host. Fertilized eggs usually hatch in water. The first larval stage, the miracidium, generally is free-swimming and penetrates a freshwater or marine snail, unless it has already been ingested by one.
Roundworms-Roundworms can complete their life cycle in immature dogs, but as the pup's immune system matures (usually by 6 months of age), the larval stages of the roundworm will become arrested and will encyst (become enclosed in a cyst) in the pup's muscles. They can remain encysted in the dog's tissues for months or years.
