How do Demetri's results show that digestive enzymes are crucial to maintaining homeostasis inside the body?

Answers

In addition to breaking down food so that the nutrients may be absorbed, enzymes also generate vitamins like biotin and vitamin K and protect the body from dangerous microorganisms.

What is homeostasis?

A biological system's ability to self-regulate and maintain stability while responding to shifting environmental factors is known as homeostasis.

The body needs a steady supply of nutrients from food that has been digested. They are crucial for maintaining health and carrying out bodily tasks. The body may absorb and use food that has been broken down by the digestive system.

What are the states of energy? List the Laws of Thermodynamics.

Answers

Answer:

The laws of thermodynamics define a group of physical quantities, such as temperature, energy, and entropy, that characterize thermodynamic systems in thermodynamic equilibrium.

Explanation:

What are the states of energy? List the Laws of Thermodynamics.
Answer: The first law, also known as Law of Conservation of Energy, states that energy cannot be created or destroyed in an isolated system. The second law of thermodynamics states that the entropy of any isolated system always increases.

Paragraph: Discuss the three laws of thermodynamics.
Key Points

The first law, also known as Law of Conservation of Energy, states that energy cannot be created or destroyed in an isolated system.
The second law of thermodynamics states that the entropy of any isolated system always increases.
The third law of thermodynamics states that the entropy of a system approaches a constant value as the temperature approaches absolute zero.
Terms

absolute zeroThe lowest temperature that is theoretically possible.
entropyA thermodynamic property that is the measure of a system’s thermal energy per unit of temperature that is unavailable for doing useful work.

System or Surroundings

In order to avoid confusion, scientists discuss thermodynamic values in reference to a system and its surroundings. Everything that is not a part of the system constitutes its surroundings. The system and surroundings are separated by a boundary. For example, if the system is one mole of a gas in a container, then the boundary is simply the inner wall of the container itself. Everything outside of the boundary is considered the surroundings, which would include the container itself.

The boundary must be clearly defined, so one can clearly say whether a given part of the world is in the system or in the surroundings. If matter is not able to pass across the boundary, then the system is said to be closed; otherwise, it is open. A closed system may still exchange energy with the surroundings unless the system is an isolated one, in which case neither matter nor energy can pass across the boundary.

A Thermodynamic SystemA diagram of a thermodynamic system
The First Law of Thermodynamics

The first law of thermodynamics, also known as Law of Conservation of Energy, states that energy can neither be created nor destroyed; energy can only be transferred or changed from one form to another. For example, turning on a light would seem to produce energy; however, it is electrical energy that is converted.

A way of expressing the first law of thermodynamics is that any change in the internal energy (∆E) of a system is given by the sum of the heat (q) that flows across its boundaries and the work (w) done on the system by the surroundings:

Δ
E
=
q
+
w
Δ
E
=
q
+
w

This law says that there are two kinds of processes, heat and work, that can lead to a change in the internal energy of a system. Since both heat and work can be measured and quantified, this is the same as saying that any change in the energy of a system must result in a corresponding change in the energy of the surroundings outside the system. In other words, energy cannot be created or destroyed. If heat flows into a system or the surroundings do work on it, the internal energy increases and the sign of q and w are positive. Conversely, heat flow out of the system or work done by the system (on the surroundings) will be at the expense of the internal energy, and q and w will therefore be negative.

The Second Law of Thermodynamics

The second law of thermodynamics says that the entropy of any isolated system always increases. Isolated systems spontaneously evolve towards thermal equilibrium—the state of maximum entropy of the system. More simply put: the entropy of the universe (the ultimate isolated system) only increases and never decreases.

A simple way to think of the second law of thermodynamics is that a room, if not cleaned and tidied, will invariably become more messy and disorderly with time – regardless of how careful one is to keep it clean. When the room is cleaned, its entropy decreases, but the effort to clean it has resulted in an increase in entropy outside the room that exceeds the entropy lost.

The Third Law of Thermodynamics

The third law of thermodynamics states that the entropy of a system approaches a constant value as the temperature approaches absolute zero. The entropy of a system at absolute zero is typically zero, and in all cases is determined only by the number of different ground states it has. Specifically, the entropy of a pure crystalline substance (perfect order) at absolute zero temperature is zero. This statement holds true if the perfect crystal has only one state with minimum energy.

Describe a time when you had to approach a complex problem by breaking it down into smaller parts that were easier to understand. Why is this type of approach helpful?

Answers

Answer

During a summer camping trip, my family struggled to set up our tent. No matter how hard we tried, the tent wouldn’t stay up. So, we decided to break down the entire process. First, we identified and labeled each of the parts we found in the tent bag, including the meshes, poles, and stakes. Next, we framed and raised the tent by inserting the poles into the mesh. Finally, we staked the tent to the ground to secure it. Breaking down a product or process can help you understand the process better.

Explanation:

Sample Answer

Approaching a Complex Problem: When I was working on a software development project, I encountered a complex coding issue. Instead of tackling the entire problem at once, I broke it down into smaller tasks, focusing on each component separately before integrating them.

During the software development project, I encountered a challenging problem that required careful consideration and problem-solving. Rather than attempting to address the entire problem in one go, I decided to apply a divide-and-conquer approach. I broke the problem down into smaller, manageable tasks that each addressed a specific aspect of the problem.

By approaching the problem this way, I was able to focus on understanding and solving each individual task more effectively. I researched and brainstormed solutions for each smaller part, ensuring that I fully comprehended the underlying concepts and challenges. Once I had solutions for each smaller task, I started integrating them to address the larger problem as a whole.

This type of approach was helpful for several reasons:

Reduced Complexity: Breaking down a complex problem into smaller tasks makes it less overwhelming. Each task becomes more digestible and manageable, allowing for a clearer understanding of its intricacies.Focused Problem-Solving: Addressing smaller components one at a time enables a more focused and targeted problem-solving process. It allows for a deeper exploration of each aspect, leading to more effective solutions.Clear Progress Tracking: Completing each smaller task provides a sense of accomplishment and progress. This motivation encourages continued work on the problem and boosts overall productivity.Enhanced Collaboration: When working in a team, breaking down a complex problem facilitates collaboration. Team members can tackle different components concurrently, leveraging their strengths and expertise.Improved Decision-Making: Analyzing each smaller part can reveal insights and nuances that might be overlooked when trying to solve the entire problem at once. This leads to well-informed decision-making.

In conclusion, breaking down a complex problem into smaller parts is a strategic approach that promotes deeper understanding, effective problem-solving, and manageable progress. It helps manage the complexity, aids in making informed decisions, and boosts overall success in addressing challenging issues.

CAN SOMEONE WHO DID THE CELERY STALK OSMOSIS LAB ANSWER THESE QUESTIONS? 50 POINTS
1. What is osmosis?

2. Celery is composed of millions of plant cells. Do these cells contain any water?
Yes
3. Did the cut celery in step 8 & 9 show any color change that would indicate that the water did enter the celery cells?

4. If you placed the celery into a bottle of colored water that was 35% sugar, would the colored water be seen in the celery? Why or why not? (HINT: Drawing a diagram of this scenario may help – 35% sugar is a very concentrated solution…)

Answers

Answer:

1. Osmosis is the spontaneous net movement or diffusion of solvent molecules through a selectively permeable membrane from a region of high water potential to a region of low water potential, in the direction that tends to equalize the solute concentrations on the two sides.

2. Plants obtain water through their roots. Water present in the soil (or air, in the case of air plants) enters the plant through the epidermis of the root. The epidermis is a very thin single layer of cells. The water passes through the membranes of plant cells and also fills the spaces in between the cells.

3. This experiment allows you and your child to talk about the circulatory system and "capillary" action. The small "vessels" in the celery stalks carry the water and color to the leaves, like the way blood travels through your body.

4. A great way to introduce basic science concepts are through fun and visual experiments such as this Celery Experiment. It requires just a few items and is a fun way to teach children about how a plant absorbs water. This process is called Osmosis. We will learn about how plants absorb water using colored water and celery stalks.

Give an example of how water acting as a solvent is important for living organisms.

Answers

Answer:Water acts as a solvent of carbon dioxide excreted from tissues, in blood and helps in regulating pH (because it forms carbonic acid that lowers pH when it tends to get higher). Blood pH should be maintained at about 7.4. One major reason is that the structure of protein is dependent ton pH because pH determines its ionization hence also affecting the charges and interaction between side groups of amino acids. A change in pH may, therefore, denature proteins and negatively affect cellular functions.
