The answer to your question is Biotechnology
OBJECTIVES
Observe different types of cells.
Use the microscope. These supplies and equipment are needed:
prepared slide of muscle tissue
prepared slide of some internal organ such as the kidney, liver, or heart
prepared slide of erythrocytes, or leukocytes (from blood)
Follow these directions and complete the activities.
1. Place one of the prepared slides of animal tissue on the stage of the microscope.
2. Focus the microscope on low power. Then change to the high power objective. Focus on the tissue, and note the cells.
3. On a separate sheet of paper, draw an individual cell that you see in the tissue. Note the shape of the cell and its other distinctive characteristics.
What do you think the function of this cell might be?
4. Repeat Steps 1 and 2 using the other prepared slides.
5. On a separate sheet of paper, draw individual cells from the other prepared slides examined.
What do you think the functions of the other cells drawn might be?
If all of the different kinds of cells which you observed had been taken from the same organism or individual, would they have all had the same genetic information?
Consider specialization: What biological concept or occurrence is demonstrated by the different kinds of cells which were observed?
Why is it important?
Answer: 434 words total. Left two questions blank (they are underlined) so youll probs need to fill it in. I also suggest putting it into your own words so if they run it through a plagerism checker this doesnt pop up. I hope this helps tho.
Introduction:
Cells are the basic building blocks of all living things. The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. Cells also contain the body’s hereditary material and can make copies of themselves. Cells have many parts, each with a different function. Some of these parts, called organelles, are specialized structures that perform certain tasks within the cell.
Materials:
• Microscope
• Prepared slide of muscle tissue
• Prepared slide of some internal organ such as the kidney, liver, or heart
• Prepared slide of erythrocytes, or leukocytes (from blood)
Instructions:
1. Place one of the prepared slides of animal tissue on the stage of the microscope.
2. Focus the microscope on low power. Then change to the high-power objective. Focus on the tissue, and note the cells.
3. On a separate sheet of paper, draw an individual cell that you see in the tissue. Note the shape of the cell and its other distinctive characteristics.
-What do you think the function of this cell might be?
4. Repeat Steps 1 and 2 using the other prepared slides.
5. On a separate sheet of paper, draw individual cells from the other prepared slides examined.
Questions:
What do you think the functions of the other cells drawn might be?
- (i think this differs on person to person so may need to do it yourself)
If all of the different kinds of cells which you observed had been taken from the same organism or individual, would they have all had the same genetic information?
- Yes, the cells will have the same genetic information. However, the particular combination of genes that are turned on (expressed) or turned off (repressed) dictates cellular morphology (shape) and function. Essentially meaning that though the cells share the same genetic information they do not necessarily share the same functions.
Consider specialization: What biological concept or occurrence is demonstrated by the different kinds of cells which were observed?
- Though these cells have the same DNA, they all have different phenotypes. The phenotypes are different because the cells appear different under the microscope. The cells do this by expressing different genes at different rates. For example, the blood cell is expressing the gene to make hemoglobulin while the other cells are probably expressing different genes that allow them to be specialized. Cells differentiate which means that they are becoming more specialized. Epigenetics focuses on how cells become more specialized.
Why is it important?
- This is important because it allows different parts of the body to carry out their crucial functions necessary for the whole body to run properly.

Answer: The correct answer is second and third statement.
Explanation:
The second and third statement are examples of the concerns expressed by opponents of the use genetically modified food crops. The second statement is related with the fear of the farmers during the harvest stage, because they consider that new genes can reach their crops, from the GM crops. The third statement is related to the fear of the some "naturalists" people who express that the protein products can lead to allergic reactions, however GM food crops have been tested regorously, and there is no evidence of any kind of allergic reaction.
Opponents of genetically modified (GM) food crops express concerns including potential allergic reactions in human consumers, the passing of new genes to wild relatives, and the possible incorporation of these new genes into human consumers' DNA.
Concerns expressed by opponents of the use of genetically modified (GM) food crops include the possibility of GM food crops passing their new genes to human consumers, the potential for GM food crops to pass their new genes to close relatives in nearby wild areas, and the risk that the protein products of transgenes in GM food crops might lead to allergic reactions in human consumers.
GM plants, also known as transgenic plants, are created by inserting DNA from one species into another species to introduce desirable traits. However, the introduction of these foreign genes presents risks including ecological instability due to the potential spread of these genes to other species in the environment. Additionally, the artificial DNA in these foods could potentially trigger allergic reactions in some individuals due to the protein products of these genes.
Further, the concern that GM food crops might pass their new genes to wild relatives stems from the possibility that this could upset the balance of ecosystems and lead to loss of biodiversity. Lastly, the worry that GM food crops might pass their new genes to human consumers may arise from a lack of understanding of the genetic modification process, as genes from food are not typically incorporated into our own DNA during digestion.

mitochondria produce water from oxygen while chloroplasts produce oxygen from water. I just did it and got it wrong because of the answer below. So mad.
Three critical things of genes are it carry all the genetic information from one generation to the next generation, it determine heritable characteristics of organisms, it is easily copied.
Gene is located within the chromosome and it is an inseparable part of a chromosome, consists of Nucleic acid that is mainly DNA.
A gene consist of 1500 nucleotides and the chemical structure of one gene does not influence on the chemical structure of other chromosomes
Number of genes is uncountable, the genes of a particular chromosome are arranged by a specific method and the place where is located called as locus
The volume of a gene may be about 1.20µ, capable of self-replicating without any change of characteristics where the new generation inherits the characteristics from their parents due to the transfer of genes.
