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.

zinc
hydrogen
nitrogen
oxygen
The elements such as carbon, hydrogen, oxygen, and nitrogen are significantly found in living organisms in excess amounts.
The characteristics of living organisms may include breathing, reproducing, excretion, increase in size, homeostasis, etc.
In living organisms, hydrogen is one of the most abundant elements followed by carbon, oxygen, nitrogen, sulphur, phosphorus, etc.
While zinc, magnesium, manganese, cobalt, iodine, copper, iron, etc are trace elements that are found in very small amounts.
Elements such as chromium, cadmium, lead, arsenic, mercury, etc. are heavy metals that are toxic to human health.
Therefore, it is well described above.

Answer:
Carbon, sulfur, hydrogen, oxygen, and nitrogen
Explanation:
a
Answer:
Growth and Development.
Explanation:
.
Capillaries; veins; arteries
Capillaries allow materials to be exchanged between the blood and tissues, veins carry blood towards the heart, and arteries carry blood away from the heart.
Capillaries are small blood vessels through which molecules such as oxygen and glucose enter the cells.
Veins are tubes or blood vessels that transport blood toward the heart. Veins mostly transport deoxygenated blood towards the heart except the pulmonary and umbilical veins, which transports oxygenated blood toward heart.
Arteries are blood vessels that transport blood away from the heart to other parts of the body. Arteries have elastic walls and they are stronger and thicker than veins.
b. increases
c. remains the same
Answer: a. decreases
Explanation:
A population density can be define as the number of individuals in a population of a species living in a unit of area in a particular time. The population density can be influenced by number of births, deaths, immigration, emigration and competition. The number of live birth in a concerned population and immigration (introduction of the new members) are likely to increase the population density of a region. But the number of deaths and emigration (the members of the same population move to a new habitat), and the competition (the members of the same species may compete among themselves for the same resources, the superior one will receive the resources and the inferior one will loose and may die) will decrease the population density.
According to the given situation, death rate and competition among the individuals will likely to decrease the population density.
Answer:
The correct answer will be- non-living.
Explanation:
The rust is a chemical compound formed through a process called rusting by the oxidation of iron in the presence of air and water.
The formation of rust is a chemical process or a metabolic process which leads to the corrosion of iron and iron erodes away or rust eats the iron. It is not considered a living reaction as it lacks other features of living beings like not takes place in a cell as well not a heredity feature.
Thus, non-living is the correct answer
Rust eating a hole in a metal bucket is a nonliving process, as the answer to the question indicates. Iron, an element present in nature, is oxidised to make rust.
When iron is exposed to oxygen and moisture, it is created. Rust is not a living thing and cannot move, develop, or reproduce on its own. It is only a type of iron that is lifeless. A chemical interaction between the metal and oxygen causes rust to chew a hole in a metal bucket.
Rust is the result of the metal's reaction with oxygen to produce iron oxide. There is no need for a living thing for this response to take place because it is not alive. It is only a nonliving chemical process.
