Which compound can only be made if it has access to magnesium ions?
Answer:
Hope it helps
Explanation:
Green plants absorb light in their leaves and convert it to energy by photosynthesis. Temperature, carbon dioxide concentration and light intensity can affect the rate of photosynthesis.Plants need minerals for healthy growth. They are absorbed through the roots by active transport as mineral ions dissolved in the soil water.Magnesium ions and nitrate ions are needed by plants. A plant will not grow well if it cannot get enough of these ions, and it will show symptoms of mineral deficiency. Fertilisers are used to replace minerals used by plants.
Nitrogen fertilisers - such as ammonium nitrate and ammonium phosphate - provide plants with water-soluble sources of nitrogen that they can absorb through their roots. They allow farmers to increase the yield and quality of their crops. However, overuse can cause problems. Eutrophication happens when excess nitrate (or phosphate) enters rivers or lakes from fields. This can lead to the death of fish and other aquatic animals.

A farmer is struggling to control the population of a certain insect on his farm. After researching population control techniques, he discovers that a particular bird is a predator of this insect. The farmer purchases a number of these birds and releases them onto his farm.
How might the farmer’s action most likely have a negative impact on the ecosystem?
The birds will increase biodiversity of native plant species.
The birds will pollinate native species, increasing genetic variation.
The birds will consume beneficial insects, as well as the pest species.
The birds will mate with native birds and create a new species.
One of the effects of the farmer's action on the ecosystem would be that the birds will consume beneficial insects along with the pest species.
Ecological effects of biological pest controlBiological control of pest requires that a living organism that will prey on the pests are introduced into the ecosystem
However, the most effective biological control of pests has to do with introducing biological agents that are very specific in action.
Using a bird species to control insect pests may lead to beneficial insects being consumed along with the insect pest in the ecosystem. The loss of beneficial insects will create a new problem in the ecosystem.

Answer:
A
Explanation:
A. Carbon cycle
Cellular respiration is the metabolic reaction that occurs in the cells of organisms. Cellular respiration and photosynthesis both add carbon dioxide to the biogeochemical cycle. Thus, option A is correct.
What is a biogeochemical cycle?The biogeochemical cycle is the process that transfers and moves the abiotic chemical factors through the various spheres of the earth. It includes carbon, water, nitrogen, phosphorus cycle, etc.
The process of cellular respiration releases carbon dioxide as the waste gas into the atmosphere that gets consumed by the plants to make energy that gets eaten by the organism that again releases the carbon dioxide. This cycle of carbon goes on from the producer to the consumer in the ecological chain.
Therefore, cellular respiration and photosynthesis contribute to the carbon cycle.

by collecting drill core samples of Earth’s crust
by measuring seismic wave activity
by analyzing how living things survive
by recording changes in climate patterns
Answer: A
Explanation: E2022
Geologists study direct evidence of Earth's interior by measuring seismic wave activity, which is the second option, as the seismic waves are waves of energy that travel through the earth's interior.
What are seismic waves?Geologists use various techniques to study the Earth's interior, but one of the most important is the measurement of seismic wave activity. Seismic waves are generated by various sources, such as earthquakes, volcanic eruptions, and human-made explosions. The waves travel through the earth's interior and can be detected by seismic instruments such as seismometers. Seismic waves come in two main types: body waves and surface waves. Body waves are waves that propagate through the earth's interior, while surface waves travel along the earth's surface. Body waves are further divided into two types: P-waves and S-waves.
Hence, geologists study direct evidence of Earth's interior by measuring seismic wave activity, which is the second option.

Ddt was widely used as a pesticide for 20 years. Its use was banned after studies showed severe side effects were evident in humans, the environment, and animals as a result of ddt. Which reason best explains why the side effects of ddt were so harmful?.
Answer:
One major side effect of DDT was the extreme damage to bird populations. DDT caused the shells of bird eggs to become extremely thin, which made them prone to breaking from minor disturbances and failing to thrive due to temperature regulation issues. It also slowly poisoned animals, especially birds that fed on insects that were poisoned by DDT. A notable bird species that was affected by DDT is the bald eagle. At one point in the 1960s, bald eagles nearly went extinct due to various effects of DDT. The threat of one of the most recognizable animals in America going extinct led to lawmakers trying to ban DDT.

"As energy is transferred or transformed, more and more of it is wasted."
In this case the second law of thermodynamics (in the simplified form presented here) says that no matter what process takes place inside the container, its entropy must increase or remain the same in the limit of a reversible process...
Explanation:
The second law of thermodynamics states that as energy is transferred or transformed, more and more of it is wasted. It's one of the four laws of thermodynamics, which describe the relationships between thermal energy, or heat, and other forms of energy, and how energy affects matter...
The second law of thermodynamics says that when energy changes from one form to another form, or matter moves freely, entropy (disorder) in a closed system increases. Differences in temperature, pressure, and density tend to even out horizontally after a while...
The second law of thermodynamics describes the nature of processes and chemical reactions as follows: processes occur spontaneously if and only if by their process, the entropy change in the universe, is greater than or equal to zero…
Second law of thermodynamics:Statement,examples and applications. The second law of thermodynamics states that heat can flow spontaneously from a hot object to a cold object; heat will not flow spontaneously from a cold object to a hot object. Carnot engine, heat engine are some examples of second law of thermodynamics .....
The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object.
Why is the second law of thermodynamics so important? Second law of thermodynamics is very important because it talks about entropy and as we have discussed, 'entropy dictates whether or not a process or a reaction is going to be spontaneous'...
His formulation of the second law, which was published in German in 1854, is known as the Clausius statement: Heat can never pass from a colder to a warmer body without some other change, connected therewith, occurring at the same time. The statement by Clausius uses the concept of 'passage of heat'...
“The first law of thermodynamics also known as the law of conservation of energy states that energy can neither be created nor destroyed, but it can be changed from one form to another.” “The second law of thermodynamics states that the entropy in an isolated system always increases.”
