Endangered forest animal is - (A) Fox (B) Blue cow (6) Golden cat (D) Peacock​

Answer:

(A) Fox

Explanation:

Answer:

Endangered Forest animal is Fox (Option a)

Explanation:

Endangered species/ animals consist of the species or animals who are likely to get extinct in the coming future.

This extinction is majorly due to the disturbances created by human beings.

Among the given options, Fox is an endangered forest animal.

The various species of fox which are endangered are as follows,

1. Arctic Fox

2.Sierra Nevada Red Fox

3. Darwin's Fox

4. Island Fox

The excessive use of natural habitats and and exploitation of species have resulted in various problem for various species such as,

1. Habitat loss and global warming which leads to the displacement of these species.

2. The large scale conversion of lands to commercial agricultural and infrastructure development.

3. Climate change and hunting  - The fox is hunted tremendously for its fur and high quality pelt.

Hence, the correct option is option(a) , that is Fox.

Explanation:

In English the core building blocks of any intellectual or research argument are paragraphs. Each paragraphs should be a single unit of thought, a discrete package of ideas composed of closely linked sentences. The most generally applicable sequence to follow is — Topic, Body, Tokens, Wrap.In English the core building blocks of any intellectual or research argument are paragraphs. Each paragraphs should be a single unit of thought, a discrete package of ideas composed of closely linked sentences. The most generally applicable sequence to follow is — Topic, Body, Tokens, Wrap.The opening ‘topic’ sentence alerts readers to a change of subject and focus, and cues readers (in ‘signpost’ mode) about what the paragraph covers. It should never link backwards to material that came before (linkages are instead always made forward in ‘wrap’ sentences). So be wary of starting paragraphs with linking words (such as ‘However’, ‘Never the less’, ‘Furthermore’), lest they lead you into looking back. Instead topic sentences should clearly signal a new focus of attention. Yet they also need to be carefully written, to give readers the impression of a fluent, ‘natural’ progression of thought. Remember too that a signpost is just that — it is a very short cuing or naming prompt, not a mini-tour guide or a preview of the whole paragraph argument to come.
Sahil performed an experiment to study the inheritance pattern of genes. He crossed tall pea plants (TT) with short pea plants (tt) and obtained all tall plants in F1 generation. a. What will be set of genes present in the F1 generation? b. Give reason why only tall plants are observed in F1 progeny. c. When F1 plants were self - pollinated, a total of 800 plants were produced. How many of these would be tall, medium height or short plants? Give the genotype of F 2 generation.

Answer:

There will be 600 tall plants and 200 short plants in the F2 Gen. There will be no medium height plants in F2 Gen. due to the fact that only extreme characters of the pea plants have been chosen...

Genotype for F2 Gen.

TT(1), Tt(2) and tt(1)

So genotypes ratio of F2 Gen = 1:2:1

Answer:

a) The set of genes present in the F1 generation is T, T, and t, t.

b) F1 progeny are all tall because of the dominance of the dominant Tall (T) gene over the recessive dwarf (tt) gene.

c) When F1 plants were self-pollinated, out of 800, 600 plants would be tall and 200 would be short plants.

d) The genotype of F2  generation- TT:Tt: tt.

Explanation:

  • The crossing was done between tall (TT) and short (tt) pea plants.
  • The offspring obtained in the F1 generation would be tall (Tt).
  • Thus, the set of genes present in the F1 generation is T, t and T, t.
  • The T (tall) gene is dominant over the t (short) recessive gene. The reason for the observation of only tall plants in the F1 generation is the law of dominance.
  • On self-pollinating the F1 plants, the plants produced would be TT, Tt, and tt.

                        Tt              X            Tt

        Progeny    TT, Tt, tT, and tt

  • Out of 800 plants produced, 600 plants would be tall and 200 plants would be short.
  • The phenotypic ratio for F1 generation is 3 Tall: 1 short.
  • The genotype of F2 generation is  TT, Tt, tT, and tt
