1 Nutrition
Living things take in materials from their surroundings that they
use for growth or to provide energy. Nutrition is the process by
which organisms obtain energy and raw materials from nutrients
such as proteins, carbohydrates and fats.
2 Respiration
Respiration is the release of energy from food substances in all
living cells. Living things break down food within their cells to
release energy for carrying out the following processes.
3 Movement
All living things move. It is very obvious that a leopard moves but
what about the thorn tree it sits in? Plants too move in various
different ways. The movement may be so slow that it is very
difficult to see.
4 Excretion
All living things excrete. As a result of the many chemical
reactions occurring in cells, they have to get rid of waste products
which might poison the cells. Excretion is defined as the removal of
toxic materials, the waste products of metabolism and substances
in excess from the body of an organism.
5 Growth
Growth is seen in all living things. It involves using food to
produce new cells. The permanent increase in cell number and size
is called growth.

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.

PLATO GANG WASSUP
The first phase is interphase, during which the nucleus divides and the DNA replicates. The second phase is mitosis, during which the cytoplasm divides. The third phase is cytokinesis, during which the cell divides into two daughter cells.
What is cell cycle ?The cell cycle is the series of events that take place in a cell leading to its division and duplication. It consists of two major phases: interphase and the mitotic phase. The mitotic phase is further divided into two stages: mitosis and cytokinesis.
During interphase, the DNA of the cell is replicated in preparation for cell division. This phase is divided into three subphases: G1 (Gap 1), S (Synthesis), and G2 (Gap 2).
During G1, the cell grows and prepares for DNA synthesis. During the S phase, the DNA is replicated, resulting in two identical sets of chromosomes. Finally, during G2, the cell prepares for mitosis.
After interphase, the cell enters the mitotic phase. During mitosis, the replicated chromosomes condense and line up at the center of the cell. The nucleus then divides into two identical nuclei, each with a complete set of chromosomes.
After mitosis, cytokinesis occurs, which is the process by which the cytoplasm divides, separating the two daughter cells. The cytoplasmic division usually occurs simultaneously with the telophase stage of mitosis, resulting in the formation of two genetically identical daughter cells.
Therefore, interphase is the phase in which DNA replicates, mitosis is the phase in which the nucleus divides, and cytokinesis is the phase in which the cytoplasm divides to form two genetically identical daughter cells.

A) Regulation will help the ecosystem to remain balanced and contribute to the stabilization of other populations of river organisms.
Explanation:
For the electricity, the use of Biomass meets the demands due to the fact that, it has minimal impact on the environment, does not add carbon dioxide to the atmosphere. Also, it is renewable form of energy.
For the regulation of the amount of fish removed from the river helps to maintain the ecosystem balance. If it was not done, the fishes found in the river will be totally harvested thereby disrupting the chains in that river ecosystem.
How has the study of genetics shaped our understanding of heredity?
Genetics is the study of how heritable traits are transmitted from parents to offspring. Humans have long observed that traits tend to be similar in families. It wasn't until the mid-nineteenth century that larger implications of genetic inheritance began to be studied scientifically.

what would happen if your body failed to return to normal after exercising? explain.
Answer: if your question has to do with homeostasis here you go! i hope this helps:)
In order for a body to work optimally, it must operate in an environment of stability called homeostasis. When the body experiences stress—for example, from exercise or extreme temperatures—it can maintain a stable blood pressure and constant body temperature in part by dialing the heart rate up or down.
The loss of too much blood may lead to circulatory shock, a life-threatening condition in which the circulatory system is unable to maintain blood flow to adequately supply sufficient oxygen and other nutrients to the tissues to maintain cellular metabolism.

What renewable energy source do you think would be best to develop first.
There is no right or wrong answer
In at least 3 sentences, please.
I believe solar power is a renewable energy source that should develop first. This is because as of right now, scientists know that they aren't as efficient as they could be. These panels are currently growing cheaper as production capabilities increases but the panels are going to rarely be able to produce efficiently due to weather conditions. If more money gets added to the research and development of this technology, these panels will become more efficient, thus making more clean energy.
Is It possible for two parents with a round jaw to have a child with a square jaw? Why or Why not
Yeah it's possible. Even though both parents have round jaws... that may be the result of a dominant trait overpowering the recessive trait. As long as both parents have the recessive gene (in other words they're heterozygous traits) then there is a possibility for a child to be born with a square jaw.
