Answer:
<em>C) Eat locally-produced and organic food; cur meat and dairy consumption.</em>
Explanation:
Eating organic food will be of no help because humans do not usually use forest trees as food resources. And hence, it will be of no help to stop the carbon dioxide emissions. Hence, option C will be of no help.
The consumption of green products will lead to lesser production of carbon dioxide and hence can be helpful. Using alternate energy sources which are not carbon based will also help to reduce the amount of carbon dioxide. If lands are restored then, these trees will not change over time. Hence, option A, B and D are helpful for no substantial change in the tree species over time.
B) Vacuoles allow water to enter and exit the paramecium.
Answer:
Those capillaries that have endothelial cells tightly attached have an increase in cell-to-cell junctions, such as desmosomal junctions that are poorly permeable to substances.
These capillaries generally function as conductors or collectors and not as permeabilizers like the pulmonary capillaries that are fenestrated and allow a high passage of substances and gases.
The capillaries are waterproof and prevent the passage of substances or fluids such as in the blood-brain barrier that is very selective
Explanation:
The blood-brain barrier is too selective since it is not favorable for the organism that many fluids, drugs, substances or chemical compounds enter the brain space.
This is the reason why the vessels are waterproof and why pharmacology was challenged to invent drugs that could cross this barrier since it was considered impossible.
An example is dopamine, which in parkynson's disease the levo group is added to dopamine, thus forming levodopamine as a product, this is the only way that the drug crosses the blood-brain barrier and can pass the impermeable barrier generated by capillaries with endothelial cells that are close to each other or closely linked
Answer:
2
Explanation:
Because if you add 1 to 8 you get 9 then subtract 9 by 7 then and your answer is 2
Answer:
The correct answer will be option-B
Explanation:
Three types of solution are formed based on the concentration of the solute which are:
1. High solute concentration- Hypertonic solution
2. Low solute concentration- Hypotonic solution
3. Equal solute concentration- Isotonic solution
When a cell contains a high amount of solute concentration and low concentration of water then it results in the generation of very high osmotic pressure.
If a cell is placed in an aquatic medium then due to high osmotic potential, the water will enter the cell which will lead to the rupture of the cell membrane. This process of rupture of the cell membrane is known as the plasmolysis.
Since the cell rupture due to the generation of very high osmotic potential, therefore, is the correct answer.
