STRUCTURAL ORGANISATION QUIZ-2
Dear Readers,NEET is the most famous and important medical entrance examination held in our country. This exam is an objective type, an offline test which includes 4 sections namely– Physics, Chemistry, Botany, and Zoology. The maximum marks that can be scored are 720 marks and have 180 questions.
About half of the paper consists of questions from Biology, as the NEET exam essentially focuses on capacitating students to go for seats in medical courses. One of the most significant and crucial sections in the NEET exam is of Biology. It comprises of theories, descriptions, discoveries, diagrams, definitions, explanations of differences, and relations. The majority of the topics covered in the NEET syllabus are from the NCERT syllabus of Class 11 & 12 and other related sources become part of the rest of the syllabus.
Clear Exam curates a list of articles selected by professionals who recommend the highly vital topics for NEET exams. The table below takes you directly to the respective topic where the in-depth article and the MCQs are available for an easy and productive learning experience.

Students will be covered for all their studies as the topics are available from basics to even the most advanced.
Q1. Find out the pair in reference to the earthworm, which is not correctly matched
Solution
Setae plays a principal role in the locomotion but not in defence against predators

Q2.A group of similar cells which along with intercellular substances perform a specific function in multicellular organisms are called
Solution
Q3. Fertilisation and development in earthworms occurs with in the
Solution
Fertilisation and development in the earthworms occurs with in the cocoon. In the cocoon, mature sperm, egg cells and nutritive fluid are deposited. The ova (eggs) are fertilised by the sperm cells within the cocoon which then slips off the worm and then gets deposited on the soil. These cocoons holds the worm embryo. After three weeks, each cocoon produces two to twenty baby worms with an average of four

Q4. Which of the following organ regulates the volume and composition of the body fluids of earthworm?
Solution
Nephridia. In earthworms, nephridia regulates the volume and the composition of body fluids. A nephridium begins as a funnel that collects excess fluid from the coelomic chamber. This funnel connects with the tubular part of the nephridium, which delivers the wastes through a pore to the surface in the body wall into the digestive tube

Q5.Which of the following statement is incorrect about the female reproductive system of frog?
I. Reproductive organs includes a pair of ovaries
II. Ovary has functional connections with kidneys
III. A mature female can lay 15000-2000 ova at a time
IV. Oviduct and ureters open separately into the cloaca
Solution
The ovaries are situated near the kidneys. A pair of oviduct arising from the ovaries opens into the cloaca separately. A mature female can lay 25000 to 30000 ova at a time

Q6. Which one of the following mammalian cells is not capable of metabolizing glucose to carbon dioxide aerobically?
Solution
Cell organelles and nucleus are absent in mature red blood cells, therefore, aerobic respiration does not take place.

Q7.Epidermis of the earthworm’s body is made up of single layer known as
Solution
The epidermis of the earthworm is made up of a single layer of columnar epithelial cells, which contains secretary gland cells
The epidermis of the earthworm is made up of a single layer of columnar epithelial cells, which contains secretary gland cells
Q8.In cockroaches,stink gland is found in
Solution
The arthrodial membrane between the 5th and 6th abdominal terga is depressed to form a stink gland. These glands produces a secretion that gives a stinky smell

Q9.Which of the following intersegmental grooves contains four pairs of spermthecal apertures on the ventro-lateral sides of the earthworm?
Solution
Four pairs of spermathecal apertures are situated on the ventro-lateral sides of the intersegmental grooves, i.e., 5th to 9th segments, i.e., 5/6, 6/7, 7/8 and 8/9 segment. They leads into spermathecae and serves to receive the sperms from another worms during copulation

Q10. Three chambered heart of the frog contain
Solution
Two atria and one ventricle. etc. A frog heart is solid muscular organ situated in the upper half of body cavity. It is three chambered with two auricles and one ventricle. The ventricle is incompletely divided by an interventricular spetum, while auricles are completely divided by interauricular spetum. Heart is covered by a membrane called pericardium. The potential space between heart and pericardium is called pericardial space. This space is fluid filled and the fluid here is called pericardial fluid. The heart of frog pumps mixed blood as lungs are not much functional is than and most of the oxygenation of blood takes place throngle skin
