Explain how thermohaline circulation is influenced by salinity and temperature.
Answer:
Thermohaline circulation is influenced by changes in density gradients. These density gradients are affected by the salinity and temperature of the ocean’s water. Cold water is denser than warm water and salt water is denser than freshwater. As water cools off, it sinks. As water evaporates, the salt concentration of the remaining water increases because the salt from the evaporated water remains. This causes the water to sink and circulate.
Explanation:
Changes in density gradients have an impact on thermohaline circulation. The salinity and temperature of the ocean's water have an impact on these density gradients.
What effect of thermohaline circulation?The distribution of heat to the polar regions is largely dependent on thermohaline circulation.
As a result, it impacts how quickly sea ice forms at the poles, which in turn affects other components of the climate system (such as the albedo, and thus solar heating, at high latitudes).
Both salt water and cold water are denser than warm or fresh water. Water sinks as it cools.
Because salt from the evaporated water persists, when water evaporates, the salt content of the remaining water rises. The water circulates and sinks as a result of this.
Therefore, thermohaline circulation is influenced by salinity and temperature.

Select the most complete model that shows the cellular structures present in all living cells.
Answer animal cells
Explanation:
The most complete model that shows the cellular structures present in all living cells is option B. So, the correct option is (B).
What is Animal Cell?An animal cell is defined as the type of eukaryotic cell that lacks a cell wall and has a true, membrane-bound nucleus as with other unicellular organisms.
Animal cells are generally smaller than plant cells. Animal cells are irregular in shape due to the absence of a cell wall. But animal cells share other cellular organelles with plant cells as both evolved from eukaryotic cells.
Animal cells consist of following cell organelles:
Cell membraneNucleusNuclear membraneCentrosomeLysosomeCytoplasmGolgi ApparatusMitochondriaRibosomeEndoplasmic reticulumVacuoleNucleoporeThus, the most complete model that shows the cellular structures present in all living cells is option B. So, the correct option is (B).

. What causes a hurricane to form
will give brainliest to smartest answer
Answer:
For one to form, there needs to be warm ocean water and moist, humid air in the region. When humid air is flowing upward at a zone of low pressure over warm ocean water, the water is released from the air as creating the clouds of the storm. As it rises, the air in a hurricane rotates.
Explanation:
In short pressure zones over warm ocean
Answer:
When warm moist air over the water rises, it is replaced by cooler air.
The cooler air will then warm and start to rise.
If there is enough warm water, the cycle will continue and the storm clouds and wind speeds will grow causing a hurricane to form.

Explanation:
i hope its help more
Answer: The equipment will "push back" on the astronaut with the same amount of force.
Explanation: Newton's third law of motion can be summed up as "For every action, there is an equal and opposite reaction." This means that when the astronaut applies force to push the object, that object will apply an equal amount of force to the astronaut.

Which of the following best describes how much precipitation and evaporation occurs over the ocean?
A) A small amount of the evaporation and precipitation
B) Most of the evaporation and precipitation
C) Most of the evaporation but a small amount of the precipitation
D) A small amount of the evaporation and most of the precipitation
Answer:
C. Evaporation occurs when the ocean water comes up to the clouds and change it from a liquid to a gas, however precipitation occurs just a tinsy bit because precipitation is actually like rain, hail, sleet, etc... so that doesn't happen all the time

if you measure the age of a fossil using 14c dating and determined its age to be about 17000 years old, how much of the rock should be made of 14N
Answer:
Geologists do not use carbon-based radiometric dating to determine the age of rocks. Carbon dating only works for objects that are younger than about 50,000 years, and most rocks of interest are older than that. Carbon dating is used by archeologists to date trees, plants, and animal remains; as well as human artifacts made from wood and leather; because these items are generally younger than 50,000 years. Carbon is found in different forms in the environment – mainly in the stable form of carbon-12 and the unstable form of carbon-14. Over time, carbon-14 decays radioactively and turns into nitrogen. A living organism takes in both carbon-12 and carbon-14 from the environment in the same relative proportion that they existed naturally. Once the organism dies, it stops replenishing its carbon supply, and the total carbon-14 content in the organism slowly disappears. Scientists can determine how long ago an organism died by measuring how much carbon-14 is left relative to the carbon-12.
The percentage of 14C is close to 12%
Carbon-14 is a radioactive isotope chemical element characterized by containing 6 protons and 8 neutrons. Its main function is the dating of organic specimens because it is present in all organic materials.
This is because once an organism dies carbon-14 slowly decreases over year as the lifespam of carbon dioxide is between 5000 and 30000 years. The way it decreases is determined by a mathematical function, but to make it easier there are graphs like the one below that show the process.
According to the graph showing the amount of carbon in an organic material when a fossil is 17,000 years old, the percentage of Carbon - 14 is about 12%.
