Destruction of coral reefs would cause an imbalance in the ecosystem. Some species could be driven to extinction.
Coral reefs are the base of the most diverse marine ecosystem in the world. They are often referred to as the ‘rainforest’ of the oceans and seas. They provide shelter for cnidarians, sponges, crustaceans, and etcetera and provide hiding grounds from predators.
Answer:
accepting electrons at the end of the electron transport chain.
Explanation:
Answer:
Answer is Sinoatrial node, SA.
Explanation:
The sinoatrial node, SA, is known to be a group of cells which are found at the top of the heart.
The electrical signal that is initiated by the sinoatrial node bring about or stimulates the atria and then the ventricle of the heart.
It should be noted that, the sinoatrial node are regarded as the pacemaker cells.
1. Depth: The water level in the Great Salt Lake fluctuates from year to year. Water levels drop and salinity increases when less water flows into the lake than usual. Not only that, but the wetlands dry up and the shoreline recedes. The reason the shoreline shifts so dramatically is because it sits at the bottom of a broad and relatively flat basin. For a visual example, think of pouring water into a plate versus a bowl.
Salinity: This Great Salt Lake has a high mineral content, as most terminal lakes are, which means that it is quite salty. Even the fresh water flowing into the lake contains small amounts of dissolved minerals. As water evaporates from the lake, the minerals stay behind. As a result, these minerals have accumulated to very high levels because they have been left behind for thousands of years. The Great Salt Lake is between 3.5 and 8 times saltier than the ocean. However, the organisms that survive in such saline conditions have adapted to their surroundings through special features.
Temperature: The Great Salt Lake has a very shallow depth, with an average of 14 feet deep and a mere maximum of 33 feet. This means that a lot of the surface area is exposed to the air, and is at the mercy of its seasonal temperature fluctuations. In the summer, rise to more than 80 degrees Fahrenheit while falling to below freezing in the winter.
2. Depth: Salinity drops and lake levels rise during high precipitation years. Wetlands get covered by salt water, and the shoreline expands, sometimes destroying wildlife habitats and killing sensitive vegetation.
Salinity: <span>Changes in lake elevation are accompanied by changes in salinity. The salinity in the lake decreases as incoming fresh water dilutes the salt water. This happens during the wet years. During dry years, however, salinity increases as continued evaporation removes fresh water.
</span>Temperature: Because of the lake's salt high content, the water doesn't usually freeze. However, as the temperature drops during the winter, less saline zones freeze solid, and most of the lake turns into a vivid pea-soup green color. In mid-March, temperatures begin to rise again as brine shrimp begin hatching. By late April, juvenile, and adult brine shrimp fill the water, serving as food for migrating and breeding birds.
3. Brine shrimp are smaller in highly salty water and larger in less salty water. Also, salinity levels also affect the rate of sexual development. Higher salinities produce adults who reach maturity quicker but are shorter in length. As salinity increases, the abdomen becomes longer relative to body length. Low salinity may also cause cysts to crack prematurely, as well as allowing other competitors into the ecosystem. High salinity results in offspring that develop quickly but are smaller and have a relatively longer abdomen. In short, effects of abiotic conditions on brine shrimp are development rate, the rate of sexual maturity, the overall length of the abdomen, amount/type of food available, cyst density and location.
4. One limiting factor of brine shrimp are predators: corixids that consume brine shrimp, grebes that consume brine shrimp and their cysts, and humans that commercially harvest brine shrimp cysts. Another limiting factor for brine shrimp is cooler temperatures. They<span> are much more productive in warmer water and consume more phytoplankton. However, when the lake water temperature is cold, the shrimp population tends to decline. </span>
Answer:
After you have established a research question, which of the following should you do first?
put your research question into a null and alternative hypothesis
Explanation:
It expedient that after research question has been established, one needs to make a null hypothesis and alternate it, this gives a clue of what the researcher intends to find or problem to be solved.
