Scientific Investigation can be tested, measured by asking in questions format.
For example - Do hand sanitizers decrease a person’s risk of a bacterial infection?
Science is more about practicing and conducting than knowing to gain and learn the actual aspect of the world.
This learning can be achieved through Scientific Investigation .
What is Scientific Investigation?A scientific investigation is a plan for asking questions and testing possible answers in order to advance scientific knowledge. The purpose of Scientific Investigation is testing ideas with evidence.
Real science is nonlinear, iterative (repetitive), creative, unpredictable, Scientists often undertake the steps of an investigation in a different sequence, or they repeat the same steps many times as they gain more information and develop new ideas.
Scientific investigations often raise new questions as old ones are answered and Successive investigations may address the same questions but at ever-deeper levels.
Alternatively, an investigation might lead to an unexpected observation that sparks a new question and takes the research in a completely different direction.
Steps involved in Scientific Investigation are:
- Step 1 - Make Observation
- Step 2 - Ask a question
- Step 3 - Forming hypothesis
- Step 4 - Making prediction based on hypothesis
- Step 5 - Do an experiment to test the prediction
- Step 6 - Analyze the result
- Step 7- Hypothesis is either Correct or Incorrect
- Step 8 - Final result based on Hypothesis
- Step 9- Try again if the given hypothesis is incorrect from Step 4.
Making Observation:
Scientific investigation typically begins with observations that is detected through human senses or with instruments and measuring devices that enhance human senses and also with our sense of touch, smell, taste, or hearing.
In addition, we can extend and improve our own senses with instruments such as thermometers and microscopes.
Hypothesis Formation:
A hypothesis is a possible answer to a scientific question based on scientific knowledge. A hypothesis also must be logical, and it is beneficial if the hypothesis is relatively simple. In addition, to be useful in science, a hypothesis must be testable and falsifiable.
A hypothesis is often expressed in the form of prediction.
Hypothesis Testing:
Hypothesis testing is at the heart of a scientific investigation. Data are essentially just observations which may be measurements in an experiment or just something the researcher notices.
A hypothesis is supported if the actual observations (data) match the expected observations. A hypothesis is refuted if the actual observations differ from the expected observations.
Analyzing the Data:
The data scientists gather raw data which are the actual measurements or other observations that are made in an investigation. Raw data usually must be analyzed and interpreted before they become evidence to test a hypothesis.
To make sense of raw data and decide whether they support a hypothesis, scientists generally use statistics.
Drawing Conclusion:
A hypothesis can never be proven conclusively to be true. Scientists can never examine all of the possible evidence, and someday evidence might be found that disproves the hypothesis.
In addition, other hypotheses, as yet unformed, may be supported by the same evidence.
The more evidence that supports a hypothesis, the more likely the hypothesis is to be correct.

Vertical structural members that exterior wall sheathing and siding may be attached to are called:
Vertical structural members in construction that support exterior wall sheathing and siding are known as studs. They are integral to the building's framework, working alongside horizontal members to ensure structural stability.
Studs are essential elements in building construction, providing structural support to the walls, akin to how horizontal beams, like vigas and latillas, support the roof. In traditional post-and-lintel construction, the vertical posts provide a similar function, bearing the weight from the horizontal lintel above doorways and other openings. In the context of a house, other vertical structures include window frames and door lintels. The role of these vertical members is critical as they work in conjunction with horizontal structures to provide stability and support to the entire building.

Lipids are a poor source of stored energy. lipids are a poor source of stored energy.
a. True
b. False
Lipids are excellent sources of stored energy in the body, contrary to the mistaken belief that they are not. They store about twice the amount of energy as proteins or carbohydrates and can be broken down for use in periods of energy requirement.
Explanation:The statement given is false; lipids are not a poor source of stored energy, but rather excellent ones. Lipids, which include fats, oils, waxes, and certain vitamins, serve multiple essential roles in the body. They act as important components of cell membranes and play key roles in signaling. However, one of their most vital functions is energy storage. Lipids pack about twice as much energy as proteins or carbohydrates per gram.
When the body needs energy, it can break down these lipid stores to provide it. This makes them a useful and efficient source of energy for extended periods without food, such as during fasting or starvation. To summarize, lipids are in reality very efficient and concentrated sources of stored energy in the body.

The scientific process is ________ involving both inductive and deductive reasoning
The scientific process is circular involving both inductive and deductive reasoning.
Further details
Scientific Process
The logical strategy is a progression of steps pursued by logical examiners to address explicit inquiries regarding the regular world. It includes mentioning objective facts, defining a speculation, and directing logical examinations. Trial results.
Steps of scientific Process
Mention an objective fact. Pose an inquiry. Structure a speculation, or testable clarification. Make an expectation dependent on the speculation. Prediction is tested. Repeat: utilize the outcomes to make new speculations or expectations.Deductive reasoning
It is the way toward thinking from at least one explanations (premises) to arrive at a consistently certain resolution. Deductive thinking goes a similar way as that of the conditionals, and connections premises with ends. On the off chance that all premises are valid, the terms are clear, and the guidelines of deductive rationale are pursued, at that point the end came to is essentially valid.
Inductive reasoning
Inductive thinking is an intelligent procedure wherein different premises, all accepted genuine or discovered genuine more often than not, are joined to get a particular end. Inductive thinking is regularly utilized in applications that include expectation, or conduct.

Which cell component functions like a "cellular delivery truck" to transport cell materials?
Which macromolecule (or polymer) is properly matched with its subunit (or monomer)?
Final answer:
Macromolecules such as proteins, nucleic acids, and complex carbohydrates are polymers made from monomers; proteins from amino acids, nucleic acids from nucleotides, and carbohydrates from monosaccharides. Lipids can be built from fatty acids and glycerol. The joining of monomers to form polymers involves dehydration synthesis, where water is released.
Explanation:
Macromolecules are essential components of living organisms, and each class of macromolecule is made from specific types of monomers. Proteins are constructed from amino acids, nucleic acids from nucleotides, and complex carbohydrates such as starches and cellulose from simple sugars like glucose. Lipids, although not always formed by monomers and polymers in the same way as the other macromolecules, can be built from fatty acids and glycerol. The process of forming macromolecules from monomers involves dehydration synthesis reactions, where water is released as monomers are linked together to form polymers.
Each macromolecule category has its own type of monomers. For example, proteins are polymers made from amino acid monomers. Each nucleic acid strand consists of monomers called nucleotides. Carbohydrates are comprised of monosaccharide monomers. For a macromolecule to be properly matched with its monomer, it must be correctly paired with the subunit that forms that specific type of polymer.

When molecules move down their concentration gradient, they move from where they are more concentrated to where they are less concentrated.
Diffusion across a biological membrane is called passive transport.
When molecules move down their concentration gradient, they naturally flow from regions of higher concentration to areas of lower concentration. This process, known as diffusion, occurs spontaneously and does not require the input of energy. The movement of molecules across a biological membrane through diffusion is categorized as passive transport. In passive transport, molecules move freely through the membrane, driven by the concentration differences on either side.
This method is essential for various cellular processes, ensuring the equilibrium of molecules inside and outside the cell. In contrast, active transport involves the movement of molecules against their concentration gradient, requiring energy input to achieve this uphill transport. Both passive and active transport mechanisms contribute to the dynamic balance and proper functioning of cells.

What is one potential reason a plant may be forced to elevate its cell respiratory rate?
Final answer:
A plant may need to elevate its cell respiratory rate due to heat stress, which occurs when temperatures exceed the optimum for growth, leading to physiological changes like increased cellular respiration to cope with increased oxygen levels and reduced photosynthesis.
Explanation:
One potential reason a plant may be forced to elevate its cell respiratory rate is due to heat stress. Plants have an optimum temperature for growth, and exceeding this temperature can induce several physiological and biochemical changes. For instance, stomata might close to limit water loss under high temperature, which restricts CO₂ uptake, decreasing photosynthesis, and leading to an accumulation of O₂ in leaf tissues. This accumulation can cause free radical O₂ to oxidize cell membrane lipids, compromising their function. Consequently, respiration within the cells increases, using more stored energy and potentially resulting in reduced growth or even death if the heat stress is severe or prolonged. Additionally, temperature acclimation is important for understanding how plants adjust to changing climates.

Where are proteins produced other than on ribosomes free in the cytosol or ribosomes attached to the er?
Beyond the ribosomes in cytosol and attached to the ER, proteins can also be produced in the mitochondria and chloroplasts of eukaryotic cells, which contain their own DNA and ribosomes that allow protein synthesis.
Explanation:Proteins can be produced in a few places in a cell, but one primary location is the ribosomes, both free in the cytosol and attached to the endoplasmic reticulum (ER). However, proteins can also be produced outside of the ribosomes, and this occurs in the mitochondria and chloroplasts in eukaryotic cells. These organelles contain their own DNA and ribosomes, which allows them to synthesize their own proteins. So, in addition to the cytosolic and ER-bound ribosomes, the mitochondria and the chloroplasts are also important sites for protein production in cells.

Which finding would support the diagnosis of respiratory acidosis?
What sections of the embedded protein chain are most likely to contain amino acids with hydrophobic r-groups? explain your reasoning?
Hydrophobic R groups are most likely to be found in the center of the protein structure because during protein folding, the hydrophobic R groups of nonpolar amino acids are positioned in the interior of the protein, hidden from the water-based outer environment.
Explanation:The sections of the embedded protein chain that are most likely to contain amino acids with hydrophobic r-groups are typically those that are embedded in the center of the protein structure. This is due to the hydrophobic (water-repelling) nature of these r-groups. Proteins often fold in such a way that hydrophobic parts are tucked away from the aqueous environment, into the protein interior.
During protein folding, hydrophobic R groups of nonpolar amino acids tend to be positioned in the interior of the protein, hidden from the water-based outer environment, whereas R groups of polar amino acids, which are hydrophilic (water-attracting), tend to be on the outside of the protein. This process is guided by hydrophobic interactions.
For instance, in alpha-helix and ß-pleated sheet secondary structures of proteins, R-groups protrude out from the protein chain. The exact positioning of these r-groups, either buried in the interior or exposed to the surface, depends on their hydrophobic or hydrophilic nature.
