Answer:
The study of mathematics as a "demonstrative discipline" begins in the 6th century BC with the Pythagoreans, who coined the term "mathematics" from the ancient Greek μάθημα (mathema), meaning "subject of instruction".[4] Greek mathematics greatly refined the methods (especially through the introduction of deductive reasoning and mathematical rigor in proofs) and expanded the subject matter of mathematics.[5] Although they made virtually no contributions to theoretical mathematics, the ancient Romans used applied mathematics in surveying, structural engineering, mechanical engineering, bookkeeping, creation of lunar and solar calendars, and even arts and crafts.
Explanation:
Answer:
Mitochondria convert chemical energy, in the form of a chemical called adenosine triphosphate or ATP for short. ATP is an energy currency that every cell in our body can use. ... Electrons are passed between the complexes of the electron transport chain and enable the cells to convert energy.
so it's 2nd (light to glucose)
Weather is an example of rapid environmental changes.
Explanation:
Environment refers to our natural world surroundings. Rapid means fast or quick. Weather around us keeps changing as the earth rotates and revolves around the sun. It changes depending on the month of the year or may change from day to night. You can also note the room temperature at different times in a day, it keeps changing mostly minorly but it does change. There are sunny, foggy, rainy, cold etc days and hence we can say that weather is example of rapid environmental changes.
Correct question: A fast swimming strong body fish such as a <u>salmon</u> which is adapted to clear fast and strong water current would most likely be found in which aquatic zone? Options in the attached file
Answer:
Source of a river zone
Explanation:
The fishes body is directly correlated with their environment and the pressures they receive from it. Those animals that are used to living in clear waters, with fast currents must be very strong, must have a hydrodynamic torpedo-like body and big and strong caudal fin to propel against the currents. These animals are used to living in water masses such as the source of a river zone.
Rivers belong to lotic environments, characterized by constant moving water.
- Profundal zone: Sunlight can not reach this zone, so there are no plants. The Water movement is very limited, and in most cases, water is not clear.
- Littoral zone: Is the transition zone, near the shore, where the light easily reaches the bottom. Usually, there is plenty of vegetation fixated to the bottom.
- Wetland zone: In general these are calm water, very rich in diversity, and a proper breeding area for a wide variety of fish.
- Source of a River zone: Rivers flow from higher to lower areas. They originate at the top of the mountains and fastly descend to finally end in a lake or in the sea.
Some species of salmons characterize by living in the sea during sexual maturity, but whenever they need to breed, they go back to the area where they were born. This is in sweet water. They swim in the river until they reach the place where they are going to oviposit. In order to do this, they need to swim against the current. Many times, females die trying to reach this special place.
