Students measured the temp of water at different depths in Lake Michigan and found the temperatures varied. What is the independent variable?
Answer:
Depth of lake
Explanation:
In simple words, The independent variable can be understood as the feature of a psychological investigation which is regulated or modified by investigators rather than by other factors. For instance, learning would have been the independent variable inside an investigation of the impact of studying on test results.
Thus, we can conclude that in the given case, depth of lake is the independent variable.

What is need to conserve freshwater?Fresh water is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids.
Fresh water is vital to life and yet it is a finite resource. Although critical to natural and human communities, fresh water is threatened by a myriad of forces including overdevelopment, polluted runoff and global warming.
With this in mind, WWF partners with communities, businesses and others to decrease pollution, increase water efficiency and protect natural areas to ensure enough clean water exists to conserve wildlife and provide a healthy future for all.

The British stopped the Axis forces from entering Egypt again. Axis positions adjacent to El Alamein were perilously close to Egypt's ports and towns, the bases used by the Commonwealth troops, and the Suez Canal. El Alamein was just 106 kilometers (66 miles) from Alexandria. However, the Axis troops couldn't stay in El Alamein permanently because they were too distant from their headquarters in Tripoli, Libya.

Why is it unlikely for stable life to develop over the first few hundred million years of Earth's history
Answer:
In simple words, there existed no living on Earth for the first few million years since the environment was unsuitable for life. The original atmosphere of the Earth had a lot of water vapor but practically little oxygen. Volcanic activity blasted substances into the atmosphere such as nitrogen, carbon dioxide, hydrogen, and water vapor, but no pure oxygenation.

Answer: D. The economy was struggling in much of 2009.
Explanation:
In 2009, the ownership of mp3 players seemed to dip from April to September and only recovered afterwards.
Laptop computer ownership may not have decreased but stopped growing and remained the same in the same period. Desktop computer decreased in ownership and even Cellphone ownership decreased as well.
This means that all four gadgets were affected in 2009 in a negative manner which means that the economy struggled in that time period in 2009.
Can hydrogen Bonds form among hydrogen chloride molecules? Why?
Explanation:
Despite its electronegativity, size of a chlorine atom is larger and hence, the electron density is low. So, HCl does not have hydrogen bonding but, HF,NH3,H2O shows hydrogen bonding.The hydrogen bond does not form because the chlorine atom is too large. Despite chlorine's high electronegativity its big size lowers the negative charge density and it is not enough to attract a hydrogen atom in a stable phase. Nevertheless, there is a small dipole-dipole attraction between adjacent HCL molecules.hope it helps.stay safe healthy and happy...The zone of convergence between sub-tropical and polar air masses, and where frequent traveling storms take place, is along the:
Answer:
The zone of convergence between sub-tropical and polar air masses, and where frequent traveling storms take place, is along the sub-polar latitudes.
Explanation:
Convergence zones are meteorological systems that have a strong impact on global climate quality. These systems are formed by the interaction of various meteorological events that occur between different latitudes.
The convergence zone, which encompasses the subtropical and polar air masses, has an influence on the amount of storms that occur frequently. This convergence zone is located along subpolar latitudes, being strongly influenced by the humidity found in this region.

When comparing groups of stars, which group has relatively low
luminosities and temperatures?
Answer: Red dwarfs
Explanation:
Red dwarfs are thought to be the coolest star out of the rest. They are also the smallest. Because they are so cool, their luminosity is low as well on account of the fact that relatively speaking, the fusion taking place on their surface is little.
Red dwarfs are the most numerous star in the universe and the most numerous in the Milky Way galaxy as well. We just can't see them with out naked eyes because of their low luminosities.

While geography may be split between physical and human geography, what are some examples you can think of that would include utilizing both to answer scientific questions
Answer:
Physical and human geography can be used to answer scientific questions such as:
"How to reduce deforestation related to environmental exploration?"
"How can the creation of borders interfere with social classes?"
"How to limit urban expansion?"
"How to reduce the problems caused by the rural exodus?"
Explanation:
Scientific issues are, most of the time, aimed at explaining and solving problems related to the physical environment and the way in which human beings are inserted in this space. It is because of these goals that physical and human geography is so important to the resolution of scientific issues, as they directly refer to the natural elements of terrestrial space and the interaction of this space with humanity. Thus, the junction between science, physical and human geography, can be useful to answer questions such as: political instability, population expansion and decrease, environmental issues, atmospheric phenomena, environmental exploration, among others.

Explanation:
pls mark me as brainlist
The impact of human activities on soil are that some human activities have clear direct impacts.
These include land use change, land management, land degradation, soil sealing, and mining. The intensity of land use also has a great impact on soils.
Measures to conserve it include crop rotation, cover crops, conservation tillage and planted windbreaks
What is land degradation?Land degradation is a process in which the value of the biophysical environment is affected by a combination of human-induced processes acting upon the land.
It is viewed as any change or disturbance to the land perceived to be deleterious or undesirable.
Natural hazards are excluded as a cause; however human activities can indirectly affect phenomena such as floods and bush fires.
It is estimated that up to 4% of the world's agricultural land is seriously degraded.
What is crop rotation?Crop rotation is the practice of growing a series of different types of crops in the same area across a sequence of growing seasons. It reduces reliance on one set of nutrients, pest and weed pressure, and the probability of developing resistant pests and weeds.
A well-designed crop rotation can reduce the need for synthetic fertilizers and herbicides by better using ecosystem services from a diverse set of crops. Additionally, crop rotations can improve soil structure and organic matter, which reduces erosion and increases farm system resilience.
