Nondisjunction - in nondisjunction, the chromosomes fail to separate at a proper state due to meiosis.
Answer:
-In Florida, it is hot and muggy year round.
Explanation:
Answer:
Ecology is the study of organisms and how they interact with the environment around them. ... Changes in ecosystems can result from many different factors including diseases among the organisms living in the area, increases in temperature, and increased human activities.
Explanation:
For questions 11-15
11. Magnesium Oxide is a combination between Magnesium and oxygen so the formula will be MgO
12. Calcium Chloride is a combination between Calcium and Chlorine, so the formula will be CaCl₂ the ₂ comes from the fact that there is two Chlorine atoms
13. Lithium Sulfide is a combination between Two lithium and a sulfur atoms,
so the formula will be Li₂S The ₂ coming from the two lithium atoms
14. Barium Selenide is a combination between Barium and Selenium so the formula will be BaSe
15. Aluminum Oxide is a combination between Aluminum and Oxygen, there are two Aluminum atoms and three Oxygen atoms, so it will make Al₂O₃
Hope this helps
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>
