Choose the true statement about the nitrogen cycle.
a. Bacteria take nitrogen from the atmosphere and convert it into sugars.
b. Nitrogen is contained in the leaves of plants such as peanuts, soybeans and clover.
c. Nitrogen makes up about 22% of the atmosphere's composition.
d. Animals release nitrogen through urination and by dying.
Answers
The true statement about the nitrogen cycle is that: b. Nitrogen is contained in the leaves of plants such as peanuts, soybeans and clover.
Nitrogen is a chemical element with the symbol "N" and it has an atomic number of 7.
Basically, it is found in group (5) of the periodic table and as such it has 5 electrons in its outermost shell. Therefore, nitrogen has two (5) valence electrons.
Nitrogen cycle can be defined as a repeating biogeochemical process which typically involves the interconversion or circulation of nitrogen and its compounds by the actions of both living organisms and non-living things in the environment such as nitrogen fixation and decomposition. Thus, it is biogeochemical process that converts nitrogen gas into organic substances and then back to nitrogen in air.
In the real world, it is known that the leaves of plants such as peanuts, soybeans and clover contain nitrogen in a very significant amount.
In conclusion, true statement about the nitrogen cycle is that nitrogen is contained in the leaves of plants such as peanuts, soybeans and clover.

Imagine that you are standing on a beach but cannot swim. Your friend encourages you to walk into the surf zone created by incoming deep water waves that a wavelength of 30 meters. Would it be safe to walk out to where the waves are breaking?
Answers
Answer:
Explanation:
The water depth in the surf zone is between 5 to 10 meters deep and with a wavelength of 30 meters, the speed of the wave is considerably fast such that control for safety may be difficult
Also the speed of the wave is directly related to the depth of the water which means that where the wave described above is fast as well as the rip current, also the water depth is expected to be considerable for a non swimmer
It is best to seek for sign post regarding safe areas and do not go into the water where there are no lifeguards or marked safe zones.

The map shows the locations of 13 major river basins in Africa: the Senegal, Volta, Niger, Lake Chad, Nile, Lake Turkana, Juba Shibeli, Ogooue, Congo, Zambezi, Okavango, Limpopo and Orange river basins. This spectacular Southern African waterfall, considered to be among the greatest in the world, is located along the Zambezi River and straddles the border between Zambia and Zimbabwe. The awe-inspiring nature of the waterfall is in part due to its enormous width—more than 5,500 feet (1,700 meters). The waters plunge as far as some 355 feet (108 meters) down and drop not into an open basin but into a dramatic-looking chasm. Victoria Falls is known for its veil of mist visible from miles away; the name given to the falls by an indigenous group is Mosi-oa-Tunya (“The Smoke That Thunders”). Victoria Falls and the adjoining areas were collectively designated a World Heritage site in 1989.

Which of the following does NOT negatively affect groundwater? Development has caused rainwater to drain into sewers instead of into aquifers. Runoff from household and agricultural chemicals filters into groundwater. Increased water consumption by humans depletes aquifers. Humans are utilizing groundwater to generate electricity.
Answers
Answer:
Humans using water to generate electricity does not negatively affect groundwater.
Explanation:
Rainwater, which is mostly fresh, drains into sewers most of the time of course. They are abundant in many towns, cities, etc. As a result, rainwater is not utilized enough, as it goes to waste when blending in with dirty sewer water. This leads to rainwater not draining into aquifers, And with the worlds population increased rapidly by the minute, consumption increases, leading to the water contained within aquifers to decrease in amount. Runoff from things such as pesticides and fertilizers is also a major issue that harms groundwater. As rain approaches, these chemicals can seep through dirt and soil, eventually going as far as to reach the groundwater underneath the surface, contaminating it. And humans utilizing water to generate electricity is more of a benefit to the environment. It is another effective way to get power, and is an alternative to fossil fuels. And using groundwater as a power source does not really affect the groundwater itself, so this is why the last option is correct.

Out of the total water resources available, the agricultural sector uses 52%; whereas the rest of the water is used by industries and households.
What are water resources?
The natural resources that provide water for consumption and other uses, are known as the water resources. For example, lakes, rivers, ponds, glaciers are some water resources.
Only 3% of the total water resources are fresh and suitable for human consumption. More than half of the total freshwater is used for agricultural activities, and about a quarter each by the industries and the households.

Geomagnetic reversals __________. Group of answer choices Provide strong evidence for sea floor spreading Reveal that polar wandering may have occurred. Were discovered by the Deep Sea Drilling Project Confirmed the existence of subduction zones Cause the movement of plates
Answers
Answer:
The answer is "Provide strong evidence for seafloor spreading".
Explanation:
The magnetic changes from east to west and vice versa are geomagnetic. geomagnetic reversals. And they can provide significant evidence of the expansion of sea bed in the rocks formed along the middle sea ridges by documenting the geomagnetic pattern of echo.
A new crust is developing from the magma explosion into the seafloor in the ocean along the mid-oceanic ridges along the mid-ocean ridges. When the magma cools, the minerals of ferromagnetism found in the magma will align as per the magnetosphere of this time.
In the event of geomagnetical revolutions, newly formed minerals will be reverse-aligned to early elements, thus registering the lithosphere on both sides of the mid-oceanic ridge. Lithosphere, one could argue, is a continual move away from oceanic crusts midway through.
