Which two of the given points are known as the twin characteristics of growth?(i) Increase in mass(ii) Increase in number of individuals(iii) Cellular organisation(iv) Cellular differentiation.(i) and (ii)(i) and (iii)(ii) and (iii)(iii) and (iv)? ›

Increase in mass and increase in number of individuals are twin characters of growth. Cellular organization and the cellular differentiation are the defining features/characteristics of living beings whereas growth is a non-defining characteristic of living beings.

Increase in body mass (by cell division) and increase in number of individuals by reproduction are considered as twin characteristics of growth.

The distinction between nominal and real values is an incredibly important one in economics. We apply the latest GDP numbers from the ONS to show how the inflation-adjusted numbers help to convey the twin characteristics of growth: positive longer-term growth but variable short-term rates of growth.

Twins can be either monozygotic ('identical'), meaning that they develop from one zygote, which splits and forms two embryos, or dizygotic ('non-identical' or 'fraternal'), meaning that each twin develops from a separate egg and each egg is fertilized by its own sperm cell.

From the given options, increased mass and increase in the number of individuals are considered the twin characteristics of growth. The mass is increased by cell division through mitosis. The mitosis is a type of cell division in which the parent cell is divided to form two cells.

Growth is quantitative, while development is both quantitative and qualitative. Growth depends on age, while development occurs throughout the lifespan. Growth generally refers to structural changes and development refers to functional changes.

Identical twins share the same genomes and are nearly always the same sex. In contrast, fraternal (dizygotic) twins result from the fertilization of two separate eggs with two different sperm during the same pregnancy. Like most other siblings, fraternal twins share half of their genomes.

Identical twins have exactly the same DNA, but they are not exactly alike. Each twin has his or her own personality, talents, likes, and dislikes. There are even diseases that appear in one twin but not the other, including arthritis, diabetes, autism, schizophrenia, cancer, and many others.

To form identical or monozygotic twins, one fertilised egg (ovum) splits and develops into two babies with exactly the same genetic information. To form fraternal or dizygotic twins, two eggs (ova) are fertilised by two sperm and produce two genetically unique children.

Reproduction is the production of offspring. There are two main forms: sexual and asexual reproduction. In sexual reproduction, an organism combines the genetic information from each of its parents and is genetically unique. In asexual reproduction, one parent copies itself to form a genetically identical offspring.

Which of the following is a characteristic of growth? ›

Growth is defined as the irreversible increase in mass, size, dry weight and number of an individual. In other words, the twin characteristics of growth include increase in mass and increase in number of individuals.

The increase in size and mass of an organism is known as growth. It is an irreversible increase of individual mass. As multicellular organisms grow, they add more cells to produce new tissues and organs.

Cell growth is the process by which cells accumulate mass and increase in physical size. On average, animal cells are ≈10 to 20 μm in diameter with a wide range of sizes, spanning from tiny red blood cells (≈5 μm in diameter) to motor neurons, which can grow 100's of micrometers in length (1).

In living organisms, growth occurs mainly by cell division. An increase in body mass and size are also considered as growth.

Complete answer:

Growth is the defining characteristic of living organisms. But, sometimes in non-living organisms, the growth is seen by the accumulation of materials on the surface. Growth of crystal, sand dunes, mountains are some of the examples where we see external growth.

Unicellular organisms grow by cell division.
