Why does a substance like caffeine not bioaccumulate but heavy metals like mercury and lead do? Explain where these toxins are stored in the human body. Hint: is caffeine fat-soluble?
Answers
Answer:
Brain, heart, lungs, liver, kidney
Explanation:
Caffeine does not bioaccumulate in our body but heavy metals like mercury and lead can accumulate because caffeine are fat-soluble and broken down into simpler substances and used by the body whereas heavy metals are not fat-soluble and also essential for our body to function normally but when these heavy metals are very in concentration it accumulated in our body and causes several problems in our body organs. These heavy metals accumulation occurs in the organs such as brain, heart, lungs, liver and kidney where it cause problems.
Caffeine is in organic molecules that are metabolized by the liver. Heavy metals are atoms that cannot be broken down. They can be sequestered in the bones or in fatty tissue (with methylmercury) and have a long residence time in the body.
These toxins are stored in the human brain, heart, lungs, liver, and kidney.
What are heavy metals and examples?
The word-heavy metal directs to any metallic chemical element that has a relatively high density and is toxic at low concentrations.
Examples of heavy metals include mercury (Hg), cadmium (Cd), arsenic (As), etc.
Thus, Heavy metals are atoms that cannot be broken down.

Explain how light exposure can affect gene expression in organisms of the same species. Provide an example.
plz dont steal points
Answers
Answer:
The greatest of environmental factors on phenotype is on phenotypic plasticity, phenotypes that may change due to changes in the environment; ex: snowshoe hare have brown-colored fur in summer/spring and white fur in winter. Environmental factors may affect gene expression which may result in normal/abnormal phenotypic changes.

Specialized cells are __________ intocells with specific functions
Answers
Specialized cells are stem cells that turn into cells with specific functions
Specialized cells are differentiate into cells with specific functions.
What is cell differentiation?Cells are the fundamental cornerstones of all life. Numerous numbers of cells construct the human body.
The process by which dividing cells alter their functional or phenotypical type is known as cell differentiation. All cells, it is assumed, derive from stem cells and acquire their functions as they mature.
In response to antigen exposure, some differentiation occurs. Differentiation alters a cell's size, shape, membrane potential, metabolic activity, and responsiveness to signals significantly.
These changes are primarily the result of highly controlled changes in gene expression and are the subject of epigenetic research.
Mesenchymal stem cells, epithelial stem cells, and muscle satellite cells are the three types of differentiated cells.
Thus, the answer is differentiation.

CO2 is released from the reaction
Answers
AnswerA. ADP and P form ATP
Explanation:
Hope this is correct!
Answer:
ADP and P form ATP
Explanation:
The high energy is released in steps and picked up by ADP and P to form the high energy phosphate (ATP). For each two hydrogens passed down the chain, three ATPs are produced. At this stage, 36 ATPs are produced from the original glucose that started out in glycolysis. After the hydrogens have given up all of the excess energy they are combined with oxygen to form water. mark me brainy plz! (^_^)
