Detailed Solution for EMRS PGT Biology Mock Test - 5 - Question 52

Ecology is the study of the distribution and abundance of organisms, the interaction between organisms, the interaction between organisms and their environment, and structure and function of ecosystems.

  • Ecology is distinguished from natural history, which deals primarily with the descriptive study of organisms. It is a sub-discipline of biology, which is the study of life.
  • There are many practical applications of ecology in conservation biology, wetland management, natural resource management (agriculture, forestry, fisheries), city planning (urban ecology), community health, economics, basic & applied science and it provides a conceptual framework for understanding and researching human social interaction (human ecology).
  • Ecology is not synonymous with environmentalism, natural history, or environmental science. It overlaps with the closely related sciences of evolutionary biology, genetics, and ethology. An important focus for ecologists is to improve the understanding of how biodiversity affects ecological function. Ecologists seek to explain:
  • Life processes, interactions, and adaptations
  • The movement of materials and energy through living communities
  • The successional development of ecosystems

The abundance and distribution of organisms and biodiversity in the context of the environment.

Just prior to flowering, internodes elongate enormously. This is called bolting. Bolting needs either long days or cold nights.

When a cabbage head is kept under warm nights, it retains its rosette habit. Bolting can be induced artificially by the application of gibberellins under normal conditions.

The gibberellins are weakly acidic phytohormones which help in longitudinal growth of stem.

There are more than 100 gibberellins reported from widely different organisms such as fungi and higher plants. They are denoted as GA1, GA2, GA3 and so on.

However, Gibberellic acid (GA3) was one of the first gibberellins to be discovered and remains the most intensively studied form.

All GAs are acidic. They produce a wide range of physiological responses in the plants.

Addition of gibberellin to a cabbage plant converts the dwarf stem into a stem which is 6-8 feet tall.

The habit of a cabbage plant can be changed drastically by the application of GA3.

Red pigment of tomato is formed by

Detailed Solution for EMRS PGT Biology Mock Test - 5 - Question 64

Phytochromes are red and far-red light photoreceptors that plays a major role in controlling many aspects of plant growth and development in response to light.

An unripe tomato is colored green by chlorophyll, the most common pigment found in unripe fruit and many vegetables.

As the tomato ripens, its colour starts to change from green to yellow and then eventually to red.

This change is due to the breakdown of chlorophyll, which in turn synthesize a red carotenoid called lycopene.

When ripe, the carotenoid can easily be seen as the dominant colour of the tomato, i.e. red.

EMRS PGT Biology Mock Test - 5 - Question 65

Which of the following statement is incorrect?

Detailed Solution for EMRS PGT Biology Mock Test - 5 - Question 65

The Darwin’s variations are small, which means they cannot bring sudden change in the life forms and they can bring change when they accumulates. While mutation are large and they bring sudden change even in the span of single generation. Mutation do not need accumulation.

Sludge digesters used in the secondary treatment uses

Detailed Solution for EMRS PGT Biology Mock Test - 5 - Question 66

In secondary treatment remaining major part of sludge is pumped into large tanks called anaerobic sludge digesters. Here anaerobic methanogenic bacteria digest the bacteria and fungi present in sludge. Bacteria produces a mixture of gases like methane, hydrogen sulphide and carbon dioxide. These gases can be used as a source of energy as it is inflammable and forms the biogas.

Which among the following is a living fossil?

Detailed Solution for EMRS PGT Biology Mock Test - 5 - Question 68

Latimeria chalumnae also known as The Coelacanth is a living fossil. It belongs to the group crossopterygii, from which amphibians are thought to be evolved. It is the oldest living fish and has survived till today without undergoing any change. It was first caught in east coast of South Africa.

EMRS PGT Biology Mock Test - 5 - Question 69

Cremaster muscles are found in which part of male?

Detailed Solution for EMRS PGT Biology Mock Test - 5 - Question 69

Cremaster muscles and connective tissues form spermatic cord and surrounds all structures passing through inguinal canal. Cremaster muscles and dartos muscles of the scrotal sac (a thin external sac of skin that is divided into two compartments, each compartment contains one of the two testes, the glands that produce sperm, and one of the epididymis, where the sperm is stored) help in the positioning of testes. When the outside temperature is low, these muscles contracts to move the testes close to the abdominal or pelvic cavity. When the outside temperature is high these muscles relax moving the testes away.

EMRS PGT Biology Mock Test - 5 - Question 70

Type of a roots found in Maize is

Detailed Solution for EMRS PGT Biology Mock Test - 5 - Question 70

In Maize, the roots arise from the lower nodes of stem to main axis and enter the soil obliquely. This types of roots are known as stilt roots. 

Storage roots: In some plants the primarily roots are modified to store food and assume various shapes. E.g. carrot, radish 

Respiratory roots: In some plants roots come out of the ground vertically upward to get oxygen for respiration, known as pneumatophores. 

E.g. rhizophore 

Prop roots: in banyan trees, roots arise from branches of stem for providing mechanical support to heavy branches as pillars.

Which of the following is not the correct statement regarding Chargaff’s rule?

Detailed Solution for EMRS PGT Biology Mock Test - 5 - Question 71

Chargaff’s put forward certain generalised postulates for double stranded DNA, called Chargaff’s rule. 

  • These postulates are applicable for double stranded DNA not for single stranded DNA. The 1st three statements are included in this rule 
  • Purine guanine is equimolar with pyrimidine cytosine. 
  • Cytosine is common to both DNA and RNA, while uracil is present only in RNA, which is not the basis of Chargaff’s rule.
EMRS PGT Biology Mock Test - 5 - Question 72

Which of the following is not the characteristics of Spring wood?

Detailed Solution for EMRS PGT Biology Mock Test - 5 - Question 72

The activity of cambium ring is not uniform throughout the entire year but marked affected by variation in external environment, i.e. climate as well an internal environment of the plants. The secondary xylem or the wood produced in different season with the differential activity of cambium. 

Characteristics of Spring wood: 

  • In the spring season, cambium is very active and produce large number of xylary elements. The vessel are produced with the wider lumens as more water is needed to meet the requirements by increasing transpiring surface in spring seasons. The wood so formed is called as spring wood or early wood. The spring wood is lighter in colour and has lower density. 

Characteristics of Autumn wood: 

  • In winter, the cambium is less active and as result, fewer xylary elements are formed and vessels have narrow lumen as the less water is needed. the wood formed during this season is called as Autumn wood or late wood. This wood is darker in color and has higher density.
