why does exposure to high temperatures cause an enzyme to lose its biological properties?
Answer:
Shape of active site changes that's why
Enzymes are affected by temperature. So, as temperature increases, enzymes activities also increases, till optimum temperature is reached. If it goes above the optimum temp, the enzymes becomes denatured or can't function anymore due to change in its active site.

Conclusion:
Be sure to answer the following reflection questions as a summary in the conclusion of your lab report:
Was your hypothesis correct? Why or why not? Be sure to include evidence from the data you collected to support your conclusion.
Based on your data, what can you infer about the length of time spent in each stage of the cell cycle?
What stages were the longest and shortest? Give a brief explanation of why these stages may have that time period.
Questions:
Using what you have learned in the lesson and the virtual lab activity, answer the following questions in complete sentences.
What differences can you see when you compare the nucleus of a dividing cell with that of a non-dividing cell?
If your observation had not been restricted to the tip of the onion root, how would the results be different?
The distinguishing visible features of each stage of the cell cycle include chromosome condensation, mitotic spindle, equatorial plate and formation of two cells.
What is the cell cycle?The cell cycle is a series of well-defined steps in the life of a cell that begins with cell growth and end with its division.
The cell division has a series of steps that may be classified according to the phenomena that occur in these phases.
For example, chromosomes condense during the first stage of cell division (prophase), where they migrate to the equatorial plate at metaphase.
In conclusion, the distinguishing visible features of each stage of the cell cycle include chromosome condensation, mitotic spindle, equatorial plate and formation of two cells.

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

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?
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.

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.

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