Part 2: Explain

Examine the heating curve of water below, and then answer the questions about it. If you require the use of a text reader, open the file Heating Curve of Water to receive the information.


Which three parts of the graph’s curve represent the solid, liquid, and gaseous state of water?

Explain your reasoning.

Which point of the graph’s curve represents the melting point of water? Explain your reasoning.

Which point of the graph’s curve represents the boiling point of water? Explain your reasoning.

What happens to the energy of water in Part B and Part D of the graph’s curve? How do you know?

Why does the temperature of the water stay the same when it melts and boils?

Now comes the hands-on part of your project! You will continue to explore phase changes by performing an experiment and creating your own heating curve. Before you begin your experiment, read over the following information.


The materials you will need for your experiment are listed below.


small pot

measuring cup (must have mL and oz markings)

spoon (wooden, plastic, or metal)

Place 14 oz of crushed ice into a small pot. Then add about 125 mL of water to it.

Using the thermometer, measure and record the initial temperature of the ice water. List this temperature in °C in the “0” minutes row of your data table in the lab handout. *Do not allow the thermometer to touch the bottom of the pot when recording measurements.

Place the pot on the stove, and turn the knob to the medium-low setting.

Using the thermometer, measure the temperature every minute until the water begins to boil vigorously. Record this data in the table on your lab handout.

At each measurement, also record what is happening to the water. Be sure to record the times of these events:

The ice melts.

The water forms steam.

The water begins to boil.

Once the water has begun to boil, stir the water constantly with the spoon.

Continue to measure and record the temperature every minute until almost all the water has boiled and the pot is close to empty.

Record the last temperature, and turn off the stove. DO NOT TOUCH THE POT WITHOUT SAFETY EQUIPMENT.

Create the x-axis and y-axis of a graph.

Label the x-axis as follows: Time (min).

Label the y-axis as follows: Temperature of Water (°C).

Along the x-axis, create and label 15 marks, one for each minute of the experiment. (Hint: The origin starts at 0.)

Along the y-axis, create and label temperature markings for every 20 degrees. (Hint: The origin starts at 0.)

Refer to the data from your experiment to plot the points on your graph. Then connect each of the data points with a line.

Look over your graph to make sure it is clear and correctly labeled.

Either save your graph as a computer file, or take a picture of your graph and upload it as a file on your computer.

Describe your experience in performing the experiment. What went well? What could have been

improved?

Examine your line graph. How does the graph’s slope change over time?

Examine your line graph. Why does the slope change?

How could you apply the knowledge gained from this experiment in the real world?

Hint: Think of cooking.

Make a prediction. How do you think adding other substances to the water would affect its

heating curve?

Anatomy
Label each of the following structures or processes.

Answers

Answer:

A - DNA

B - mRNA

C - nuclear pore

D - tRNA

E - ribosome

F - rRNA

Explanation:

The entire structure illustrates the process of transcription and translation in a typical eukaryotic cell.

The DNA (A) in the nucleus of the cell is first transcribed to mRNA (B). The mRNA produced is transported to the cytoplasm through the openings within the nuclear membrane - the nuclear pores (C). On getting to the cytoplasm, the mRNA binds to the ribosome (E) (carrying rRNA, F). The tRNA (D) carrying the specific anticodon for a particular codon on the mRNA then binds to the structure and the corresponding amino acid is released. A polypeptide bond is formed between subsequent amino acids and the ribosome moves along the mRNA chain until the translation process is complete.

What are the potential advantages and disadvantages of a major shift from the hard or traditional path of energy development to the soft or visionary path?


(These were the corresponding textbook pages, if needed) Please read the following from the textbook Environmental Science:

7th Edition - Chapter 17

9th Edition - Chapter 14

Answers

It’s terms in the set 10

Answer:

Advantages of following the soft path, the argument here is alternative sources of power such as hydropower, geothermal energy , wind energy , and photovoltaic cells must be developed. This provides a alternative source to remain in a healthy environment and also function as the society we currently live in using the hard path.  Disadvantages of following the hard path result with future generations fearing over the irreversible damage of climate change and the damage done to our atmosphere. The hard path argue that we should continue to operate in the future as we have in the past, except more efficiently. This is close to impossible and will only continue the negative effects the hard path( the path we have been following) results in. The major shift determines the outcome of this world, the futures worries or reliefs and ultimately the survival of humans.

Explain how each type of infectious agent (bacteria, virus, fungi, and parasite) affects the body.

Answers

There are five major types of infectious agents: bacteria, viruses, fungi, protozoa, and helminths. In addition, a new class of infectious agents, the prions, has recently been recognized

Answer:

bacteria-Some bacteria help to digest food, destroy disease-causing cells, and give the body needed vitamins. Bacteria are also used in making healthy foods like yogurt and cheese. But infectious bacteria can make you ill. They reproduce quickly in your body.

Virus-A virus infects your body by entering healthy cells. There, the invader makes copies of itself and multiplies throughout your body. The new coronavirus latches its spiky surface proteins to receptors on healthy cells, especially those in your lungs.

fungi-When fungal organisms enter the body and the immune system is compromised these fungi grow, spread and invade into tissue and spread locally. Some organisms, especially yeast and some molds, can invade the blood vessels and cause infection in the bloodstream and distant organs.

Parasite-When the worms live in the body they can cause sickness. They may get into the stomach and gut and eat the food before the body has digested it. This means that the body does not get enough nourishment. Sometimes the worms will find their way into other parts of the body, such as the blood or liver.

The sugars of a DNA and RNA molecule are alternated with in the backbone of the strand

Answers

Answer:

A phosphate backbone is the portion of the DNA double helix that provides structural support to the molecule. DNA consists of two strands that wind around each other like a twisted ladder. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups. Attached to each sugar is one of four bases--adenine (A), cytosine (C), guanine (G), or thymine (T). The two strands are held together by bonds between the bases, with adenine forming a base pair with thymine, and cytosine forming a base pair with guanine.

How is the brain involved with the senses and what is the relationship to the wat a personreacts to objects?

Answers

Answer:

The senses are the components of our nervous system that capture stimuli from the environment for transmission to the brain, and it is there where the information is processed to issue a response. All sensations are electrical signals that travel through neurons which form a network that communicates all organs with the center of the nervous system, and communicate with each other to transmit the electrical impulse through a process known as synapsis.

Explanation:

The brain is an organ that controls the activity of the body, both its conscious and unconscious functions. It is located in the head and corresponds, therefore, to the encephalon of humans and other vertebrates and is subdivided into forebrain, midbrain and hindbrain.  

The brain acts on the rest of the organism by generating muscle activity or by the production and secretion of chemicals called hormones. Thereby the brain controls responses to changes in the environment. Some basic types of response such as reflexes may be mediated by the spinal cord or peripheral ganglia, but sophisticated intentional control of behavior based on complex sensory information requires the integration of information.

The thalamus, which is located in the central part of the brain, processes and coordinates the messages from the senses that it receives from the body. Five senses are considered to exist: sight, touch, smell, taste and hearing. For that, the information perceived from the outside must reach the brain.

The senses are the components of our nervous system that capture stimuli from the environment for transmission to the brain, and it is there where the information is processed to issue a response. Therefore, all sensations perceived from the outside are electrical signals that travel through neurons. For example, the eyes transform light signals into electrical impulses, which travel to the brain where they are transformed into electrical signals.

Neurons form a network that communicates all organs with the center of the nervous system, and communicate with each other to transmit the electrical impulse through a process known as synapsis, which is mediated by molecules called neurotransmitters. Since the electrical impulse cannot jump directly from one neuron to another, these neurotransmitters are needed. When the active neuron produces them, the next neuron in the network detects them and becomes electrically charged. Once this has happened, it produces neurotransmitters again so that the next one becomes electrically activated. This is how the electrical impulse reaches the brain.

What is the difference between flu viruses and the measles virus?

Answers

Answer:Influenza and measles are viruses that both cause respiratory symptoms. The typical measles rash does not appear for 2-4 days, so during influenza season, symptoms of early measles can be confused with influenza.

Explanation:

Explanation:

Vaccines for both measles and flu already exist, however the flu vaccine must be updated because of the virus's ability to change and adapt in order to invade cells in the human body. The goal of researchers was to find genes in each virus that cannot survive changes.

By comparing two similar viruses which attack the body in similar ways through the lungs, researchers confirmed that the measles virus is much less open to evolutionary change by using an experimental technique called insertional mutagenesis to change the genes of each virus.
