Nitrate and Sulfate are alternative electron acceptors. With the use of these it would not use oxygen so It would be Anaerobic Respiration..hope this answer helped.
Inner core was found to be solid after observing the motion of P waves.
Explanation:
Seismologist Inge Lehmann, studied the seismic waves of an earthquake and discovered about inner core in the mantle layer of Earth. She States that there is a boundary of discontinuity between the outer and inner core of Earth.
She studied the travel of secondary and primary waves during an earthquake and how it flows at different shells of Earth's layer which helped her in finding about the inner core of mantle. She observed that the inner core is a solid layer inside the molten layer of outer core
As for this question, the answer would be B. kidney.
GU system or what they call as the Genitourinary system and may also be referred to as urogenital system is the system of both the reproductive system and the urinary system. They can be classified together into one system due to their immediate proximity, their origin during the embryological stages, and also the usage of a common organ. Rectum would be part of the excretory system. Lymph nodes would be of the lymphatic system and the adrenal gland would be in the endocrine system.
The right answer is True.
A watershed is the expanse of territory drained by the waters of rivers and lakes, which in turn converge to a common outlet. Groundwater is flowing into the watershed, although the boundaries may not exactly coincide with surface water. Smaller flow areas that feed subwatersheds can be called catchment basins or drains. Watersheds can flow into river basins that may encompass larger areas.
Known watersheds are separated from one another by ridge lines, also known as watersheds. These are designed to delineate the watershed.
Watersheds are nested networks, the smaller ones nesting in larger ones. Streams that form the watershed can be organized according to a ranking framework. For example, the upper streams at the highest elevation of the watershed are first class streams.
When two first-class rivers meet, they form a second-rate stream. When two second-rate rivers meet, they form a third-class watercourse. A stream joined by another lower ranking stream retains its rank. For example, a third-class watercourse joined by a first or second-rate watercourse remains a third-rate watercourse.
