What is a good property of an indicator?

Answers

Answer 1

Answer:

Acid base indicators are weak and acids and bases, which are used to signify the end point of neutralization reaction. The type of indicator used for a neutralization reaction depends on the strength of the acid and the base, that are involved in the reaction. A good acid base indicator must have a good pH range and it must be able to produce specific and identifiable color in specific acid base medium.

or

Two good properties of an indicator are as follows-

1) It should be specific- It means that the changes, which are measured by the indicator should be expressed in precise terms so that appropriate assessment could be made.

2) It should be time bound- This means that the measurable changes should arrive withing a particular time limit.

Example of indicator- Litmus is an acid base indicator that turns acidic solutions red and basic solutions into blue color.

Explanation:

El modelo atómico de Thomson, también conocido como el modelo de pudín de pasas, describe el átomo como un elemento compuesto por electrones de carga negativa embebidos dentro de una nube de carga positiva, tal como un pudín de pasas. Thomson fue el científico que descubrió los electrones en 1904, año en el que no se tenía mucha información aún de la interacción de las partículas subatómicas. En el modelo atómico de Thomson los electrones estaban distribuidos uniformemente, flotando alrededor de una nube de carga positiva.

Answers

Answer: RNA

Explanation:

Nearly all the RNA found in a typical eukaryotic cell is rRNA. Transfer-messenger RNA (tmRNA) is found in many bacteria and plastids.

What is generally found both inside and outside of the nucleus of a eukaryotic cell is ; RNA

RNA is formed in eukaryotic cells when DNA contained in the nucleus of the cell is transcribed/synthesized. The transcribed RNA is then moved out of the nucleus into the cytoplasm.

The RNA contained in the cytoplasm is later transcribed into protein in the cytoplasm of the cells . therefore RNA is contained both inside and outside the nucleus of a eukaryotic cell.

Hence we can conclude that what is generally found inside and outside the nucleus of a eukaryotic cell is RNA

Which is required for sexual reproduction? 1.mitosis 2.binary fission 3.diploid cell production 4.meiosis

Answers

Answer:

4. Meiosis

Explanation:

Mitosis creates cells for growth and repair, not for sexual reproduction. Binary fission is a form of asexual reproduction, not sexual reproduction. Diploid cell production is mitosis (mitosis creates diploid cells, or cells with a full set of chromosomes)

Meiosis is the correct answer. Meiosis creates gametes or sex cells that are necessary for sexual reproduction. Through this cell division process, 4 gametes are produced. The cells that are produces are haploid, which means they only have half of a full set of chromosomes. The cells are haploid because, during fertilization, a sperm (male sex cell) and egg (female sex cell) fuse. The result is a diploid zygote with half of the genetic information from the father and the other half from the mother.

The correct answer is 4. Meiosis.
