Which blood corpuscle help in coagulation of blood?

  • Lymphocyte

  • Platelets

  • Monocyte

  • Red blood corpuscles



Coagulation is a complex process by which the blood forms clots to block and then heal a lesion/wound/cut and stop the bleeding. It is a crucial part of hemostasis - stopping blood loss from damaged blood vessels. In hemostasis, a damaged blood vessel wall is plugged by platelet and a fibrin-containing clot to stop the bleeding, so that the damage can be repaired. Coagulation involves a cellular (platelet) and protein (coagulation factor) component. When the lining of a blood vessel (endothelium) is damaged, platelets immediately form a plug at the site of the injury, while at the same time proteins in the blood plasma respond in a complex chemical reaction, rather like a waterfall, to form fibrin strands which reinforce the platelet plug.


A person using a lens as a simple microscope sees an

  • inverted real image

  • inverted virtual image

  • upright real image

  • upright virtual image


upright virtual image

A simple microscope is nothing but a single biconvex lens. It is referred to an as magnifying glass. Its use image upright and virtual.

  • Robert Hook

  • None of the above

  • petrol

  • kerosene

  • lubricant oil

  • ligroin

Conduction of thermal energy takes place in

  • solids

  • liquids

  • gases

  • All of these


All of these

In heat transfer, conduction (or heat conduction) is the transfer of thermal energy between regions of matter due to a temperature gradient. Heat always flows from a region of higher temperature to a region of lower temperature and results in the elimination of temperature differences by establishing thermal equilibrium. Conduction takes place in all forms of matter, viz. solids, liquids, gases, and plasmas, but does not require any bulk motion of matter. In solids, it is due to the combination of vibrations of the molecules in a lattice or phonons with the energy transported by free electrons. In gases and liquids, conduction is due to the collisions and diffusion of the molecules during their random motion.


In yeast asexual reproduction takes place through

  • Budding

  • Fission

  • Both (1) and (2)

  • None of these



Yeast are unicellular (some are multicellular) eukaryotic micro-organisms belonging to the kingdom fungi. Yeast size can vary greatly depending on the species, typically measuring 3-4 pm in diameter. Most yeasts reproduce asexually by an asymmetric division process called budding. First, it produces a small protuberance on the parent cell that grows to full size and forms a bud. The nucleus of the parent cell splits into a daughter nucleus and migrates into the daughter cell. The bud detaches from the mother's body by forming a constriction at the base. Budding will repeat to form a chain of bud cells. The daughter cell produced during the budding process is generally smaller than the mother cell.


Which of the following method will you use to develop an aquarium?

  • Heuristic method

  • Problem solving method

  • Project method

  • Programmed method


Project method

Project method of teaching is one of the standard teaching methods. With this method students can develop independence and responsibility. They can also practice social and democratic modes of behaviour. Project method of teaching first became popular in 1590 in architectural schools in Europe.


Which of the following topic is suitable for a unit plan?

  • The meaning and concept of the systems of the body.

  • The blood circulatory system

  • The different systems of the human body

  • The blood and respiratory system


The different systems of the human body

A unit plan is developed by the teacher and serves as a long-range plan. It contains multiple lessons that are related to a particular unit. In a given question teacher the unit plan for teaching the different system of human body as it can be further divided into chapters while other options show content of individual chapters.


The concept of "Seed germination" can be best taught by

  • showing germinated seeds to the class and explaining the process of germination

  • presenting the different stages of germination through drawing on the board

  • showing photographs of seed germination

  • asking the students to sow seeds, observe and draw the different stages of germination


asking the students to sow seeds, observe and draw the different stages of germination

The highest form of learning occurs when all the senses are utilized, hence when the learners will sow the seeds themselves and observe they will come up with their own observations, which will be authentic , also there could be new things which they could make out which cannot be told to them, so they will discover the phenomenon themselves .
