The products and processes developed through scientific and engineering processes is the best definition of technology.
How to define technology?Technology, or as it is sometimes referred to, the modification and manipulation of the human environment, is the application of scientific knowledge to the practical goals of human life. the method a company employs to transform inputs into outputs. Positive technological change is also described as. the capacity to generate more output from the same inputs. the capacity to generate the same output with fewer inputs.
What is the scientific engineering process?While the scientific method requires students to use an experiment to test their hypothesis, the engineering design process asks them to construct a prototype. Testing and redesigning are opportunities provided by the engineering design process. The scientific method gives students the chance to evaluate the findings.

Pretend you are looking through a microscope at cells from different human organs. In which organs would you expect to find cells with the most mitochondria? The most lysosomes? The most ribosomes? Explain your answers.
Answer:
Muscle cells need a lot of energy to expand and contract, so they have a large number of mitochondria, which burn glucose for energy.
Lysosomes are responsible for holding and releasing enzymes to break down many different molecules for many different purposes. One of the major functions of the liver is metabolizing nutrients and toxins the body ingests, which is done using enzymes. So liver cells would have the most lysosomes compared to other organs.
Ribosomes are a key part in protein synthesis, which every cell does. Though, the liver is responsible for most of the protein production for the body, so liver cells would have the most.

Which correctly distinguishes between how a pine tree and an apple tree reproduce?
Answer:
Pine seeds develop in the bracts of the female pine cone and are not surrounded by fruit. The apple seed grows in the ovary of the apple flower and is surrounded by a fleshy wall that grows into the fruit.
Explanation:
How does the pine tree reproduce?
Male pine cones produce pollen, which is like a powder. The male cones release their pollen, which is carried around the air by blowing wind, and hopefully to another female pine cone on a different pine tree. If the pollen reaches a female pine cone, this process is called pollination
How does an apple tree reproduce?
Flowering plants --including the apple tree--reproduce by transferring pollen from the male organ or stamen of one blossom to the female organ or pistil of another. Some flowering plants require no pollinating partner--the flowers are sel- fertilizing.
Which of the following statements best describes why most animal fats are formed from saturated fatty acids?
The hydrocarbon chains of saturated fatty acids are straight so they can be tightly packed to store more energy in less space.
The hydrocarbon chains of saturated fat cannot pack together closely, which keeps the animal from becoming too large.
The hydrocarbon chains of saturated fatty acids allow fewer hydrogen atoms to bond, which makes the molecule stable for energy storage.
The hydrocarbon chains of saturated fatty acids have bends so they can be loosely packed to store more energy in less space.
Answer:
The hydrocarbon chains of saturated fatty acids are straight so they can be tightly packed to store more energy in less space.

D. REACH
Many people do not want landfills sited near their homes, but they do want their trash to go somewhere. This is called option A. NIMBY
A landfill is, quite honestly, a plot of land it really is used to unload waste. think about a sea of damaged, foul-smelling rubbish that has been buried and left to rot for years on an unused piece of land.
The useful resource Conservation and healing Act (RCRA), enacted in 1976, is the primary Federal regulation within the U.S. governing the disposal of solid waste and dangerous waste.
CERCLA stands for the complete Environmental reaction, repayment, and Liability Act, recognized additionally as Superfund. It was exceeded in 1980 in reaction to some alarming and decidedly unacceptable risky waste practices and control happening inside the Nineteen Seventies.
NIMBY, an acronym for the phrase now not in my back backyard, is a characterization of competition by residents to proposed trends of their nearby place, in addition, to a guide for strict land use rules.

In the early 1900s Alfred Wegener proposed the continents were “drifting.” The scientific community did not support his theory due to a lack of scientific evidence. Using what you just heard, would you support Wegener’s hypothesis or not?
Answer - The main reason that Wegener's hypothesis was not accepted was because he suggested no mechanism for moving the continents. He thought the force of Earth's spin was sufficient to cause continents to move, but geologists knew that rocks are too strong for this to be true.
Answer:
No, I would not.
Explanation:
I would not support his theory, due to the lack of information, and he had no good conclusion on why or how they were drifting

How does Claire's diagnosis explain why 1 mL of liquid from her small intestine digested
protein slowly but 1 mg of her pure protease digested protein normally?
Type your answer here
According to Claire's diagnostic, her small intestine either lacks or just has a very little number of proteolytic enzymes. Proteins in the body or on the skin are broken down by proteolytic enzymes.
What is protein digested into by protease?Any of a set of enzymes that divide proteins into shorter pieces (peptides), and subsequently into their constituent amino acids, is known as a proteolytic enzyme. It is also known as a proteinase, protease, or peptidase.
Protease is yet another crucial enzyme for the effective breakdown of meals. Proline dipeptides from gluten and casein, as well as proteins and polypeptides from plants and animals, are all primarily broken down by it.
Proteins are broken down into amino acids by protease. Lipids, which are fats and oils, are broken down by the enzyme lipase into glycerol and fatty acids.
