Answer and Explanation:

The scientific method is a research method used to produce knowledge. It consists of systematic observations, measures, experimentation, analysis, and verification of a hypothesis. It is based on two aspects: reproducibility (the capability of reproducing the experiment in any other place by any researcher) and refutability (susceptibility to be refused).

There are different steps to follow in a scientific method:

• Definition and problem statement. The question for which there is not an answer yet.

• Hypothesis formulation.  

• Data collection and analysis. This step involves testing the observations.

• Results

• Verification of the hypothesis. This step involves the acceptance or rejection of the working hypothesis.

• Conclusions and Discussion.  

In the exposed example:

Let us imagine that the scientist only wants to evaluate the performance of the new adhesive connecting only two previously determined metals: Metal A and metal B. Let us also assume that there is only one exhisting adhesive, apart from the new one that is being tested. Finally, we might also assume that he has already done bibliographic research to know better about the requirements for adhering metals and the properties of the adhesive material needed to do so. The problem might have been related to the need of getting a better adhesive.  

The scientist did not perform the experiment with the existing adhesive. The scientist did not compare the performance of the previously existing adhesive to the new one.

The scientist should have performed the experiment with two treatment groups:

The scientist also should have repeated the treatment at least two or three times for each group.

Finally, the scientist should have compared results between the performance of the two adhesives before reporting them.

Genetic variation is increased by meiosis

During fertilisation, 1 gamete from each parent combines to form a zygote. Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. This produces a unique combination of genes in the resulting zygote.

The correct answer is -Use all the data that was truly observed, not partial data that is expected or desired, skewing results.

Explanation:

In general, all practices and research should be guided by moral and ethical principles, which guarantees the research and practices are objective and participants are not harmed. In this context, an example of these principles is "Use all the data that was truly observed..." because it is ethically and morally correct to report the data that was found in the experiment or research and avoid modifying it based on financial interests, expectations, desires, etc. Also, this principle makes the research or practice objective.

Answer:

Pretty sure it's C.

Ciliates are the groups of organisms which include the protists that reside within the cells of corals. Thus, the correct option is D.

The ciliates are a group of protists which are characterized by the presence of hair-like organelles called as cilia on their membrane which are identical in structure to the eukaryotic flagella, however these are in general shorter and present in much larger numbers than that of flagella, and also with a different undulating pattern than flagella.

Cilia occur in all members of the group and are variously used in the activities such as swimming, crawling, attachment, feeding, and sensation.

Therefore, the correct option is D.

Answer: B would be the best answer

Explanation: The primary difference that lies between these organic compounds and inorganic compounds is that organic compounds always have a carbon atom while most of the inorganic compounds do not contain the carbon atom in them. Almost all the organic compounds contain the carbon-hydrogen or a simple C-H bond in them.

Option B is the right answer.

Organic compounds contain carbon and inorganic compounds do not.

Organic compounds contain one or more carbon atoms covalently linked to atoms of other elements, most commonly hydrogen, oxygen, or nitrogen. Carbides, carbonates, and cyanides are among the few carbon-containing compounds that are not classified as organic.

Organic compounds have covalently bound carbon, hydrogen, and frequently other elements. In chemistry, an inorganic compound lacks carbon-hydrogen bonds, i.e. is not an organic compound. Inorganic chemistry is a discipline of chemistry that studies inorganic compounds.

The most obvious difference between organic and inorganic substances is that organic compounds are primarily the outcome of the activity of a living being. In contrast, inorganic chemicals are obtained through natural processes unrelated to any of the Earth's life forms.

The relationship between gut bacteria and we the host is a mutualistic relationship. This is a form of relationship where both we and the bacteria benefit from the bacteria living in our gut.

They help us in our digestion process to break down some food particles into their basic units, some of which we would not be able to do without them. They also help to keep the gut’s surface intact, provide vitamins, and fight off other harmful bacteria.

Bacteria use immunity genes to neutralize toxins and protect themselves against been destroyed by our immune system by copying our immune resistance code, and using this code to make their outer membrane.

Answer:

This looks like a covalent bond between 2 atoms. Notice that the 2 electrons in the middle are being shared by both atoms, which is a feature of covalent bonds.

Explanation:

So answer should be "C"

Hope this help have a nice day!

The image depicts the sharing of electron between two atoms which form covalent bond. Thus, option C is correct.

The force of attraction between different constituents like atoms, ions which hold them together is called as chemical bonding.

Different types of bonds formed either from the loss or gain or sharing of electrons between two atoms/molecules.

Ionic bonding in which transfer of electrons from one atom or molecule to another there by generation of opposite charges on individual atoms.

The organic compound exhibit covalent bond that is sharing of electrons between atoms. it can be either polar or non-polar in nature.

Polar covalent chemical bond refers to unequal sharing of electrons between more and less electronegative atom. Water is the best example.

Hydrogen bond can be formed between oxygen and hydrogen where hydrogen develops partial positive charge so that electron can come closer to more electronegative atom.

Answer:

It slows down

Explanation:

Because water is denser than air the sound waves move through it faster which means that if the sound wave is coming from the water to the air then it will slow down. Also i took the test and got it right.

When a sound wave moves from air to water It slows down.

Sound is a mechanical wave that travels across a medium by means of the back and forth vibrating of its constituent particles. When a sound wave travels through air from left to right, the energy of the sound wave will cause displacement of air molecules in both the right and left directions.

The direction of the energy flow is parallel (and anti-parallel) to the particle motion. Sound waves in the air are described as longitudinal waves because of this.

Therefore,  When a sound wave moves from air to water It slows down.

Answer:

Choosing protein as macromolecule.

Explanation:

The given environmental changes can lead to structural changes in protein as well:

pH - Several amino acids contain sidechains with practical gatherings that can promptly pick up or lose a proton. Changes in pH would prompt an adjustment in the charge of the amino acids, prompting charge-charge attraction or repilsion between non-interfacing amino parts.  

Temperature - High temperatures can prompt protein denaturation. Warmth can upset hydrogen bonding and hydrophobic interactions.  

Reduction or oxidation Environment - Some tertiary structure of protein folding is held by disulfide linkages. Reducing agent will lead to unfolding by introducing itself to break disulfide bonds.

Effect of these change: Sequence of amino acid and structure of protein molecule form determines function, any slight change to a protein's structure may result in the protein to become dysfunctional or produce different product.

Explanation:

The unified cell theory was proposed by three scientists in the 1830's, they are: Mathias Scleiden, Theodor Schwann and Rudolf Virchow. They proposed three components that makes up the widely accepted cell theory. The components are:

1) Cell is the basic and fundamental unit of all living things

2) All living organisms are composed of one or more cells.

3) Cells arise from already existing cells

Based on these components of the cell theory, a STRAWBERRY is the household item that would be composed of cells because it is the only living thing (plant) in the option.
