What is osmosis? ???​

Answers

Answer 1

Answer:

In biology, osmosis is defined as the net movement of water molecules through a semipermeable membrane (e.g. cell membrane) from an area of higher to an area of lower water potential. Other definitions of osmosis are as follows:

The process of a solvent diffusing through a semipermeable membrane from an area of low solute concentration to an area of high solute concentration

The tendency of water to flow from a hypotonic solution (low concentration of dissolved substances) to hypertonic solution (higher concentration of dissolved substances) across a semipermeable membrane

In chemistry, osmosis is defined similarly. It is the passage of a pure solvent from a solution of lesser to one of greater concentration of solutes when the two solutions are separated by a membrane that selectively prevents the passage of solute molecules while allows the solvent molecules to pass through.

how do indicators help to observe things that are too small to see

Answers

Indicators are substances which possess measurable and observable characteristic which can be used to depict a the acidic or alkaline nature of a substance.

Indicators may be natural, those which exists naturally in nature such as litmus or turmeric.

Indicators such as Phenopthalein or Methyl orange are artifical indicators as they are obtained through laboratory preparation.

Blue litmus paper turns red when dipped into an acid while Red litmus turns blue when in contacts with a base.

Hence, indicators helps to know when a change in pH value of solution occurs.

Indicators change color in the presence of certain substances, which can be used to identify and quantify those substances.

An indicator is a chemical compound that changes color in the presence of another substance. This property of indicators can be used to observe things that are too small to see, such as individual cells or bacteria.

For example, the indicator litmus paper is red in acidic solutions and blue in basic solutions. This means that by dipping a piece of litmus paper into a solution, you can determine whether the solution is acidic or basic.

Another example of an indicator is the dye methylene blue. Methylene blue is colorless in acidic solutions, but it turns blue in basic solutions. This means that by adding a drop of methylene blue to a solution, you can determine whether the solution is acidic or basic.

Indicators can also be used to quantify the concentration of a substance in a solution. For example, the indicator phenolphthalein is colorless in acidic solutions, but it turns pink in basic solutions. The deeper the pink color, the more basic the solution is. This means that by measuring the intensity of the pink color, you can determine the concentration of the base in the solution.

Indicators are a valuable tool for observing things that are too small to see. They can be used to identify and quantify different substances in solutions.

Here are some additional details about how indicators work:

Indicators work by changing their structure in the presence of certain substances. This change in structure causes the indicator to change color.The color change of an indicator is reversible. This means that the indicator will return to its original color when the substance that caused the color change is removed.The color change of an indicator is specific to the substance that caused it. This means that a particular indicator will only change color in the presence of one specific substance.

Indicators are a versatile tool that can be used in a variety of applications. They are used in laboratories to identify and quantify different substances in solutions. They are also used in everyday products, such as litmus paper and pH test strips.

what is the number of paired processes in the thoracic bony vertebra?

Answers

Answer:

There are six facets per thoracic vertebrae: two on the transverse processes and four demifacets—the facets of the transverse processes articulate with the tubercle of the associated rib. The demifacets are bilaterally paired and located on the superior and inferior posterolateral aspects of the vertebrae.

Explanation:

Each thoracic vertebra has six facets: two on the transverse processes and four demifacets, which articulate with the tubercle of the corresponding rib.

Thus, The superior and inferior posterolateral sides of the vertebrae each have a pair of demifacets that are bilaterally paired.

There are 12 bony thoracic vertebrae in the human thoracic spine. Transverse processes are the two paired processes that each thoracic vertebra has.

Numerous muscles and ligaments can attach to these transverse processes, which extend laterally on both sides of the spine. They are crucial in assisting in mobility and supporting the spine.

Thus, Each thoracic vertebra has six facets: two on the transverse processes and four demifacets, which articulate with the tubercle of the corresponding rib.
