  2. Metatheria

  3. Prototheria

  4. None of the above

Show answer
Correct Option: C
Explanation:

A. Eutherians are called placental mammals, in which the mothers carry their unborn.

  • In them, the scrotum is present behind the penis.
B. Metatherians are also called marsupials or pouched mammals, the young are born immature and for further development takes place in mothers pouch. in the mother's pouch. 
  • In them, the scrotum is present in front of the penis.
C. Prototherians are called egg-laying mammals.

  • In them scrotum is absent.
  • So, the correct answer is 'Prototheria'.

Binomial system of nomenclature means that every organism has___________

zoology plant taxonomy nomenclature in classification nomenclature of animals introduction to plant kingdom

  1. Two names, one scientific and the other popular

  2. One name given by two scientists

  3. One scientific name consisting of a generic and specific name

  4. A number in an international catalogue by which it can be identified

Show answer
Correct Option: C
Explanation:
 C Linnaeus, the father of taxonomy, introduced the binomial system of nomenclature. He dealt about this in the 10th edition of his book 'Systema Naturae' which was published in 1785.
This is a system of providing organisms with distinct scientific names which consist of two words, the first one indicating a generic name (Genus). The first and second together form a specific name (Species). These two words are in Latin or Latinized if derived from other languages.
Genus is a common noun and starts with a capital letter. It indicates the name of a group. In the specific name, the second word is like an adjective and begins with a small letter excepting the cases when it denotes proper nouns like the name of a person, place or the like. It may then, start with a capital letter.
The names when written should be underlined to indicate their Latin origin. In the printed form, they should be italicized.
The name of the author who has first described the plant in scientific journals may be appended in full or abbreviated form. For example - the botanical name of mango is Mangifera indica Linn. All three comprise binomial nomenclature.
The generic name is one for all species whereas the species name is variable. For example - Ficus bengalensis, Ficus religiosa, Ficus glomerata, which represent banyan, peepul and fig trees respectively. All have one generic name Ficus but their species names are F.bengalensis, F.religiosa, F.glomerata.

Who proposed the 'Binomial Nomenclature System'?

  1. Whittaker

  2. Mendel

  3. Carl Linnaeus

  4. Tippo

Show answer
Correct Option: C
Explanation:

The binomial system of nomenclature was introduced by Carolus Linnaeus. In this system, he gave scientific names to plants and organisms in which the first part is 'genus' and the second part is 'species'.

A major problem with polynomial names was that they were

zoology taxonomy and systematic botany nomenclature in classification nomenclature of animals introduction to plant kingdom binomial nomenclature nomenclature of organisms

  1. Inaccurate

  2. Cumbersome

  3. Not descriptive

  4. In Latin

Show answer
Correct Option: B
Explanation:

  • The term nomenclature means the scientific naming of organisms according to an established system. In earlier days common vernacular names were used which generally changes with change of language. Later in the haunt of one common internationally accepted name for a species, scientific names (Technical names) have been introduced in the form of polynomial, binomial and trinomial systems of nomenclature.
  • In the early seventeenth century, taxonomists started using a string of descriptive Latin words to designate a species. For example, in the herbal of Clusius (1583) a species of willow is named as Salix pumila angustifolia altera.
  • Polynomial nomenclature was discarded for the two main reasons that it was lengthy and difficult to remember, it often varies from place to place, scholar to scholar based on the characters chosen by them.
So the correct option is 'Cumbersome'.

Which structure gives us ability to speech?

zoology the age of adolescence human respiration the mechanism of breathing breathing and its movements

  2. Vocal cord

The vocal cord has two small bands of muscle within the larynx. These muscles vibrate to produce the voice. It is a V shape inside larynx. When we talk, the vocal cord tightens up and move closer together and air from lungs forced between them and make then vibrate, producing the sound.

So the option B, Vocal cord is correct.
