What is mercury bioaccumulation? What are the main issues with that type of bioaccumulation?what organisms does it affect? What are the causes? What could humans do to prevent it?
Bioaccumulation is the total accumulation of certain chemicals/contaminants in an organism, coming from diverse sources such as water, air, and diet. Therefore the case of mercury occurs when mercury is accumulated in an organism, for example, fish. The most common pathway for this to happen is through the food chain, nonetheless can occur through abiotic means, an example is in fish, where methylmercury is acquired through the gills.
When methylmercury is absorbed through the gastrointestinal tract & enters the bloodstream and goes rapidly to other parts of the body.
Mercury is a persistent substance, which can bioaccumulate, in living organisms, inflicting increasing levels of harm on higher-order species such as predatory fish and fish-eating birds and mammals through a process known as "biomagnification"
The release of processed mercury can lead to a progressive increase in the amount of atmospheric mercury, which enters the atmospheric-soil-water distribution cycles where it can remain in circulation for years. Mercury poisoning is the result of exposure to mercury or mercury compounds resulting in various toxic effects depending on its chemical form and route of exposure.
The major route of human exposure to methylmercury (MeHg) is largely through eating contaminated fish, seafood, and wildlife that have been exposed to mercury through the ingestion of contaminated lower organisms.
King mackerel, marlin, orange roughy, shark, swordfish, tilefish, ahi tuna, and all contain high levels of mercury.
Human activity is the main cause of mercury release, especially coal-fired power stations, residential coal burning for heating and cooking, industrial processes, waste incinerators, and as a result of mining for mercury, gold, and other metals.

Energy is also transformed from one type to another. Describe what happens to these four substances, light energy, and chemical energy during photosynthesis. Then write a simple equation for the substances and another for energy, using words and arrows to illustrate these changes.
My friends answer is:
Photosynthesis is the process by which plants use light energy to convert water and carbon dioxide into sugars and oxygen. During photosynthesis, light energy is absorbed by the plant and converted into chemical energy. The water and carbon dioxide are broken down into their component parts, and the oxygen is released into the atmosphere. The sugars are stored in the plant for later use. The equation for photosynthesis can be represented as light energy + water + carbon dioxide → sugars + oxygen. The equation for energy transformation can be represented as light energy → chemical energy.

the opposite process from nitrogen mineralization by the soil microflora is: group of answer choices ammonification by the soil microflora. nitrification by the soil microflora. nitrogen immobilization by the soil microflora. denitrification by the soil microflora.
The opposite process from nitrogen mineralization by the soil microflora is nitrogen immobilization by the soil microflora.
This is because nitrogen mineralization is the process by which organic nitrogen compounds are converted into inorganic forms such as ammonium and nitrate by soil microorganisms, making them available for plant uptake.
Nitrogen immobilization, on the other hand, is the process by which soil microorganisms use available inorganic nitrogen to build their own biomass, making it temporarily unavailable for plant uptake. This can occur when there is an excess of organic matter or when the ratio of carbon to nitrogen in the soil is high, leading to a shortage of available nitrogen for plant growth.

The major form of phosphorus found in plant foods is phytic acid. The correct option is b.
Phytic acid, also known as inositol hexaphosphate or IP6, is a compound found in many plant-based foods, particularly in seeds, grains, legumes, and nuts. It is considered the primary storage form of phosphorus in plants.
In the context of nutrition, phytic acid can have both positive and negative effects. On one hand, it acts as an antioxidant and may have some health benefits, such as reducing the risk of certain chronic diseases. On the other hand, phytic acid can bind to minerals, including calcium, iron, zinc, and magnesium, forming complexes that are not easily absorbed by the human body. This can potentially lead to reduced bioavailability of these minerals.
To mitigate the potential negative effects of phytic acid, various food processing techniques such as soaking, fermenting, and cooking can help to reduce its levels and improve mineral bioavailability in plant-based foods.

AAA (codes for the amino acid lysine, Lys) being mutated to AAG (which also codes for Lys) are some silent point of mutations.
One of the three forms of substitution mutations (also known as point mutations), along with nonsense and missense, is a silent mutation. A silent mutation specifically happens when a change in a gene's DNA sequence has no impact on the subsequent amino acid sequence of the protein it codes for. Since both of those codons translate to the same amino acid, Ser, or serine, there is no actual change in the protein produced by this gene if the DNA sequence changes from AGC to AGA, for instance. However, the matching RNA would change from UCG to UCU. Because it has no immediate impact, the mutation is said to be "silent."
