Answer:
The function of a root hair is to increase the surface area available for absorption in plant roots
Explanation:
Root hairs are located mostly near a plant's root tips. Most water absorption occurs through the root hairs due to its large surface area for absorption of water. The root hairs acts as a protective mechanism to prevent harmful bacterial organisms from infecting the plant via the xylem vessels.
<span>The contraction of the diaphragm causes an increase in the height of the thoracic cavity. Contraction of the intercostal muscles causes the diameter of the thoracic cavity to increase. The increased thoracic cavity volume brings a volume increase in intrapulmonary volume, which causes a drop in pressure relative to atmospheric pressure. Air rushes into lungs along this pressure gradient until intrapulmonary and atmospheric pressure are equal.</span>
Answer:
Explanation:
It is carried out by nitrogen-fixing bacteria. The bacteria live in soil and roots of legumes, such as peas. When plants and other organisms die, decomposers break down their remains. In the process, they release nitrogen in the form of ammonium ions.
Answer:
mixotrophs
Explanation:
Myxotrophism or myxotrophy, in biology, is the name given to the quality of the living being with autotrophic and heterotrophic characteristics. That is, it is capable of producing its own food from carbon dioxide fixation (through photosynthesis or chemosynthesis), but it can also feed on other inorganic or organic compounds. Mixotrophic can be either eukaryotic or prokaryotic.
Carnivorous plants are commonly cited as myxotrophic organisms in the wrong way because all their food comes from photosynthesis. These plants only depend in part on the nitrogen contained in animal proteins that they digest. This dependence occurs because the carnivorous plant is native to areas with poor, soggy soil, scarce of nitrates, essential for the synthesis of the chlorophyll molecule.
