We know that oil floats on water and do not mix
<span>
What happens to the oil when you first pour it in? It flows into the water, but then seperates.
Why does this happen? oil is lighter than water and the molecules of the oil are attracted to the other oil molecules, not water, the water molecules the same
What kinds of animals would be most affected by an oil spill at the beginning? animals that live their lives near the surface of the ocean. Why? because now the water that was clear and free-flowing is now dark and sticky. oil also changes the way how some animals survive so make their ways less effective. one example are birds like pelicans
Use a spoon to stir the oil for 30 seconds.
Answer the following questions:
What natural action stirs the real ocean? ocean currents caused by wind and the earth's roation
What happened to the oil? went back to the top
Even if you can’t see it, is all the oil still in your ocean? yes
Which animals in the ocean become affected after wave and current
action causes some of the oil to settle to the bottom, or be absorbed
into the water? bottom-feeders
Add a splash of dish detergent to the mixture and stir.
Answer the following questions:
What happened to the oil? it mixed with the water Is it all still in the ocean? yes
Sometimes cleanup efforts involve dumping a soap mixture over a spill area. Why is this done? to bond the oil to the detergent and the detergent to the water. so they can grab all the oil
What might be a negative effect of dumping the soap?</span> soap has chemicals that could upset the ballance of the ecosystem and kil some animals/plants
Answer:
The correct answer is- TAAGCCGATAAATGCTAACGGTA.
Explanation:
DNA is a nucleic acid molecule made of two strands. Each strand is made up of nucleotide bonded via phosphodiester bonds. Each nucleotide is made up of- 5C deoxyribose sugar, a phosphate group and nitrogenous bases.
DNA replication produces an exact copy of the DNA molecule through complementary base pairing. The complementary strand is formed by adding nucleotide through DNA polymerase which adds base pairs according to the Chargaff rule. The Chargaff rule states that A will bind T via two hydrogen bonds and G will bind C via three hydrogen bonds.
Therefore, the complementary strand will be-TAAGCCGATAAATGCTAACGGTA
<em>carbon has four valence electrons in its outermost shell .. which makes it able to form four bonds to complete its valence shell ..
it forms large number of chains with its own self which makes it useful .. also it forms bonds with oxygen and hydrogen forming large organic compounds of great importance ..</em>
<span>The question is what would happen if you are given pure water in an IV. The answer is, the pure water will disrupt the osmotic balance of the body. Saline solutions are usually used in IV, this is because, there is a need to maintaint the osmotic pressure between the body cells and body fluids. Cell membranes are selectively permeable, infusing the body system with pure water will make pure water to rush into cells, dilute the contents and make the cells to swell up.</span>
Answer: Reproductive Cell
Explanation:
Meiosis is a specialized form of cell division that produces <u><em>reproductive cells</em></u>, such as plant and fungal spores and sperm and egg cells. In general, this process involves a "parent" cell splitting into two or more "daughter" cells.
