Answer:

Cellular Respiration: a process able to extract a large amount of energy from food molecules.  In eukaryotic cells oxygen is a required component. This metabolic process is the main reason that animals have elaborate gas exchange organs such as lungs, gills and other systems. The goal of these systems is, of course, to get access to oxygen and to get rid of carbon dioxide.

Answers

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

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.

Which of these graphs represents the effect of temperature on the rate of photosynthesis? Explain your answer.

WILL MARK BRAINLIEST!!

Answers

a. A describes the effect of light intensity on photosynthesis.

Answer: A

Explanation:
In plants and other primary producers, photosynthesis is a biological mechanism that is vital to energy production. Energy-containing carbohydrates are derived from light, water and carbon dioxide in the form of glucose molecules.
The waste product oxygen is released as a result. Photosynthesis depends on many variables, including:
carbon dioxide concentration,
ambient temperature
and light intensity
It is a rate-limited reaction. Since photons or particles of light provide the energy required for the reaction, high intensities of light increase the photosynthetic rate. From the graph shown, as the intensity increases steadily, so does the rate- but at too high of an intensity, it ceases to affect the rate of photosynthesis, which becomes constant or plateaus.
Beyond this point, either the supply of carbon dioxide or the temperature limits the reaction. For instance, at high intensities tissues may even be damaged by high temperatures or heat.

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.

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.

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).

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.
