Answer:
It acts as a catalyst to break down harmful bacteria.
Explanation:
The bacterial cell was is made up of murein also called peptidoglycan. The active site of the enzyme lysozyme binds with the molecule of peptidoglycan attacking and breaking it. It degenerates the bacterial cell wall eventually killing the bacteria.Lysozyme mostly, works on the gram-positive bacteria as the peptidoglycan layer is present on the outer side of the cell wall unlike gram-negative where it is present in the inner side of the cell wall. Thus, acting and functioning as a catalyst that breaks down walls of bacteria, enhances innate immunity, and protects from infection.For more information:

Which of these graphs represents the effect of temperature on the rate of photosynthesis? Explain your answer.
WILL MARK BRAINLIEST!!
Graph A represents the effect of temperature on the rate of photosynthesis.
Why is photosynthesis affected by temperature?Photosynthesis is a biological process that is essential to the synthesis of energy in plants and other primary producers. Light, water, and carbon dioxide combine to generate glucose molecules, which are the building blocks of energy-containing carbohydrates.
As a result, the waste product oxygen is emitted. Numerous factors affect photosynthesis, such as the amount of carbon dioxide present, the surrounding temperature, and the amount of light. It is a reaction with a rate constraint. High light intensities accelerate the rate of photosynthetic reaction because photons, or light particles, supply the energy needed for the reaction. According to the graph, the rate rises steadily as the intensity does, but at a certain point, the intensity stops having an impact and the rate of photosynthesis plateaus or becomes constant.
Beyond this point, the reaction is restricted by either the temperature or the carbon dioxide supply. For instance, at high intensities, heat or high temperatures may even harm tissues.

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.
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.

explain what a species is and how resources lead to species biodiversity.
Species are organisms which have similar characteristics and are capable
of interbreeding. A common example is we human beings.
Resources leads to species biodiversity as a result of organisms moving
from one place to another in search of food for its survival. The availability
of resources will lead to an increase in reproduction and species
biodiversity as more organisms will be present in the area.
Scarcity of resources on the other hand results to lower species biodiversity
and decreased reproduction rate.

30 POINTS!!! If a forest burns down, which stage of the water cycle is interrupted in that ecosystem, and why?
a. Transpiration
b. Precipitation
c. Infiltration
d. Evaporation
Answer:
A.TRANSPIRATION
Explanation:
Trees have deeper roots than other plants, which implies they can access and pump up larger soil water volumes for transport to the leaves for transpiration and growth. ... The energy needed to evaporate all that water is withdrawn from the environment and leaves the system as embedded latent heat.
Which means if the forest got messed up the transpiration would be jacked up

what would happen to the carrying capacity of the ecosystem & why
Q-a volcano covers an area with 2 feet of lava
Answer:
The carrying capacity would shoot downward.
Explanation:
The area would no-longer be able to support organisms or the ground until the lava cools off. Even after then, any plants that may have been there will be gone, meaning that the ecosystem can now support less herbivores, as well as less primary producers (plants).
Less plants, means less herbivores, which means less of the animals that eat the herbivores (secondary and tertiary consumers).

Answer:
The Pull of the Planets is a 30-minute activity in which teams of children model the gravitational fields of planets on a flexible surface. Children place and move balls of different sizes and densities on a plastic sheet to develop a mental picture of how the mass of an object influences how much effect it has on the surrounding space.
This activity should be conducted after Heavyweight Champion: Jupiter!, which allows the children to discover the force of gravity in the solar system. These concepts involve more advanced science than previous activities in Jupiter's Family Secrets, and they explore more deeply the science of the Juno mission and the rich information it will return to us.
