Why is recycling important to the environment?
Help
Answer: Recycling helps protect the environment
Explanation:
Recycling reduces the need for extracting (mining, quarrying and logging), refining and processing raw materials all of which create substantial air and water pollution. As recycling saves energy it also reduces greenhouse gas emissions, which helps to tackle climate change.

vacuole is a cell organelle which contains mainly water while lysosomes also cell organelle and are regarded as s u i c i d e bags by function. Vacuoles stores the undigested nutrients while the Lysosomes are the membrane bound sa cs containing digestive enzymes that breaks down large molecules.
Determine the number of sheets of plywood needed to lay the subfloor of a building that measures 24' wide and 64' long. what is the total square footage of these pieces?
No. of Sq. Pieces:
Total Sq. Ft.:
Answer:
48 pieces1536 ft²Explanation:
The 24' dimension is 6 times the 4' dimension of a 4×8 ft piece of plywood. The 64' dimension is 8 times the 8' dimension of a 4×8 ft piece of plywood.
Hence, it will take 6×8 = 48 pieces of plywood to cover the floor.
The area of the floor is the product of its dimensions:
24' × 64' = 1536 ft²
Answer:
48 pieces1536 ft²* The total square footage of these pieces.

c. The use of components that save energy, such as intelligent supply pressure adapting systems
Answer:
materials and components
Explanation:
____ is a system of manufacturers ensuring their products meet exact specifications.
A. Specification
B. Insurance
C. Quality control
D. Accuracy
Answer:
C. Quality control
Explanation:
"Quality control" refers to monitoring and ensuring the product's quality through a specific benchmark. This can be done through a process of "testing" the products by inspectors for their quality before being sold in the market. If a product doesn't pass the criteria, it will be evaluated carefully in order to learn which part of the production process made an error.
This system varies according to the different business types. For example, food manufacturers will focus more on the taste of their food and how the product appears while car manufacturers will focus more on the assembly of parts.
What form of joining uses heat to create coalescence of the materials?
Describe the make-up of an internal combustion engine.
Pls answer quickly.
Answer:
The engine consists of a fixed cylinder and a moving piston. The expanding combustion gases push the piston, which in turn rotates the crankshaft. Ultimately, through a system of gears in the power-train, this motion drives the vehicle's wheels.

Explain why relying on a concentrating solar power system would not be the best choice for an alternative energy source in the Columbia River Basin in Washington State.
Answer:
Concentrating solar power (CSP) plants use mirrors to concentrate the sun's energy to drive traditional steam turbines or engines that create electricity. The thermal energy concentrated in a CSP plant can be stored and used to produce electricity when it is needed, day or night. Today, roughly 1,815 megawatts (MWac) of CSP plants are in operation in the United States.
Parabolic Trough
Parabolic trough systems use curved mirrors to focus the sun’s energy onto a receiver tube that runs down the center of a trough. In the receiver tube, a high-temperature heat transfer fluid (such as a synthetic oil) absorbs the sun’s energy, reaching temperatures of 750°F or higher, and passes through a heat exchanger to heat water and produce steam. The steam drives a conventional steam turbine power system to generate electricity. A typical solar collector field contains hundreds of parallel rows of troughs connected as a series of loops, which are placed on a north-south axis so the troughs can track the sun from east to west. Individual collector modules are typically 15-20 feet tall and 300-450 feet long.
Compact Linear Fresnel Reflector
CLFR uses the principles of curved-mirror trough systems, but with long parallel rows of lower-cost flat mirrors. These modular reflectors focus the sun's energy onto elevated receivers, which consist of a system of tubes through which water flows. The concentrated sunlight boils the water, generating high-pressure steam for direct use in power generation and industrial steam applications.

Explanation:
all of the following are part of a cylinder head except
All the following are part of a cylinder head, except the combustion chamber. The correct option is B.
What are the different cylinder parts?
The cylinder head's cast-in intake and exhaust apertures connect the manifolds to the corresponding valves. Due of the space requirements for head bolt bosses, valve guides, cooling channels, and push-rod opening clearance, an ideal design is not always feasible.
A spark plug fires an electrical bolt over a tiny gap, igniting the gasoline and air mixture that moves the pistons and starts your car moving. They manage how much fuel enters the combustion chamber and for how long throughout the power stroke, guaranteeing maximum combustion and efficiency.
Therefore, the correct option is B. Combustion chamber.

In a paragraph of 125 words, distinguish the engineering design process from the reverse engineering process, citing at least three differences.
The difference between the engineering design process and the reverse engineering process are there, but very subtle. The engineering design process is a process based on careful planning and months of designing to create a blueprint for a certain project. The reverse engineering process is the base of learning to create something by working backwards on a previously made inspiration for your project. Three differences are that that the engineering design process doesn't require any physical learning and is more based on mental and written learning (unlike the reverse engineering process). Another difference includes that in the reverse engineering process you don't need to take anything apart and learn how things work based on the on hands aspect of this variety of engineering. The final difference is that the engineering design project is made fresh from your own thoughts and not based off of a similar project.
Answer:
The correct answer will explain that the engineering design process begins with a specific need, including the specifications and limitations of a design. If a current product or object does not match the need, then engineers will create a new design. The purpose of the engineering design process is to create or improve a design. Reverse engineering is more of an exploratory process, without the need to create a product that fits limitations and specifications. The reverse engineering process does not necessarily seek to improve a design so much as to understand the design. The key actions in this process include analyzing the structure and functions for the goal of recreating the same or similar functions. To determine which process to use, the engineer must identify his or her project goals.
What topic do Aerospace Engineers and Marine Engineers share as areas of
knowledge necessary to perform their duties.
Answer:
Fluid mechanics (dynamics)
Explanation:
The topic Aerospace Engineers and Marine Engineers has to do with the (common) environment of the equipment Aerospace Engineers and Marine Engineers work with which are air (gas) and water (liquid) both of which are classes of fluids
Therefore, the common topic shared by both professions is fluid mechanics which has branches of fluid statics (fluids at rest) , fluid kinematics (fluid having motion), fluid dynamics (the interaction of fluids in motion, and forces acting on them)
Given that both professions have energized equipment exerting forces in moving fluids, their common topic of knowledge is fluid dynamics
Fluid mechanics is a branch of physics, which is a branch of natural science which is one of the eight areas of knowledge.
