The answer to this question is DNA ONLY!
C. Dependent variable
The independent variable is what you want to change (ex amount of light given to plants)
The dependent variable is what changes because of the independent variable (ex the height of the plants)
So Independent is what you change, Dependent is what you measure
The total volume of the gas-exchanging region in the lung is called alveolar volume.
The alveolus is an air sack-like organ in the end of the respiratory airway. The alveolus is the site where gas-exchanging happens, so only air inside alveolus that will undergo actual exchange. Air in bronchus or trachea wouldn't do exchange
Answer:
A. Populations of native wetlands plants will recolonize the land.
Explanation:
From many years' wetlands are converted into farmlands as they provide retention of soil, proper food and clean water, and the cycling of nutrients. But wetlands should not be permanently converted<em> because it can increase the load on soil and add pollutants (pesticides or fertilizers) in the soil and groundwater.</em>
If the farming stops and water flows on the land again, the native plants present in wetlands will help to recolonize the land which is disrupted by farming activities.
Hence, the correct option is A.
Answer:
Capillaries, the littlest and generally various of the veins, structure the association between the vessels that divert blood from the heart (supply routes) and the vessels that return blood to the heart (veins).
Explanation:
Capillaries, the littlest and generally various of the veins, structure the association between the vessels that divert blood from the heart (supply routes) and the vessels that return blood to the heart (veins). The essential capacity of capillaries is the trading of materials between the blood and tissue cells.
Blood vessels a cylindrical organization all through the body that permits blood to spill out of the heart to each body cell and afterward back to the heart. The three kinds of veins are corridors, vessels, and veins. Each vein comprises of a layered divider encompassing a focal blood-containing space, or lumen.
