Answer:

Differentiated Cells

Explanation:

Differentiated cells are specific cells from specific tissues that have the ability to change into completely different and specific types of tissues. This phenomenon is referred to as Trans differentiation or cell differentiation.

One of the best examples of this phenomenon is the transformation of bone marrow derived stem cells into different types of pancreatic cells to treat different diseases and ailments.

Studies show that de-differentiated cells become modified into differentiated cells for multiple purposes such as tissue regeneration, repair, formation of new organs. This phenomenon occurs during the stage when the body of organism develops from a very small embryo e.g human embryo where it undergoes various cell divisions and differentiated cells become specialized to form differentiated cells or tissues with a specific function. You can see attached image for better understanding.

Hope it helps!

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

Is ductility considered as a physical property or a chemical property
Elena L [17]

Ductility is a physical property.

A physical property of a material is a property that can be measured or observed without changing the composition of the material.

In this case ductility is a physical property. It is defined as the  property of a material associated with the ability to be drawn or stretched into a wire without breaking. The chemical identity of the material is not affected, that is  it does not change.

Example of ductile materials include gold, silver, copper, erbium, terbium and samarium.

Other examples of physical properties are:

1. Solubility

2. Melting point.

3. Boiling point.

4. Color

5. Density.

Use the chart above to determine which substitution mutation has the potential to cause more damage? Highlight your answer. (2pt
icang [17]

Answer:

This question is incomplete

Explanation:

This question is incomplete because of the absence of the chart referred to in the question. However, what appears to be the case is that the three nitrogenous bases represent codons (and the missing chart is the codon chart). The mutation that has the potential to cause more damage will be the one that would change the amino acid formed from the codon change.

A. CAU to CAC: The codons CAU and CAC both form the amino acid histidine and thus is not expected to cause a major damage.

B. UGU to UGC: The codons UGU and UGC both form the amino acid cysteine and thus is not expected to cause a major damage.

C. UCU to UUU: <u>Codon UCU forms the amino acid serine while the codon UUU forms the amino acid phenylalanine</u>. Thus, this eventual change in the amino acid formed has the potential to cause a major damage and thus option C is the correct option.

NOTE that a codon is a sequence of three DNA/RNA nucleotides that corresponds to a single amino acid.
