Weekly Quiz Competition
  • Question 1
    1 / -0
    In Earthworm, gizzard occurs in segment
    Solution
    In earthworm, a terminal mouth opens into a buccal cavity which leads into a muscular pharynx. A small narrow tube, oesophagus continues into a muscular gizzard (8-9 segments). It has a thick wall of circular muscles lined by columnar cells which is further lined by the cuticle. The gizzard grinds the food into a fine state. It helps in grinding the soil particles and decaying leaves. The gizzard uses stones that the earthworm eats to grind the food completely.
    So the correct answer is '8'.
  • Question 2
    1 / -0
    Enzyme found in saliva of cockroach is
    Solution
    The salivary secretions in cockroach help in the partial digestion of food. The saliva contains enzymes such as amylase, chitinase and cellulase enzymes.
    So, the correct answer is 'D'.
  • Question 3
    1 / -0
    Number of segments in the anal cerci of Cockroach is
    Solution
    The abdomen bears 8 pairs of stigmata, anus and a pair of anal cerci. Anal cerci are developed from the junction between 9th and 1Oth segments on the dorsal side one on each side. The total number of segments present in anal cercus 15. They occur in both male and female cockroaches. They are regarded as the appendages of the vestigial eleventh segment. Therefore the number of segments in the anal cerci of Cockroach is 15.
    So the correct answer is '15'.
  • Question 4
    1 / -0
    In Cockroach which one is absorbed in hepatic caeca
    Solution
    Hepatic caeca produce digestive enzymes. With the help of these digestive enzymes, the digestion of food takes place in the mesenteron. Here digestive enzymes are poured by hepatic caeca. These digestive enzymes contain gastric amylase, maltase, invertase tryptase, and lipase.
    The digestion of carbohydrates, proteins, and fats is completed. Hence in the cockroach, both Glucose and amino acids are absorbed in hepatic caeca.
    So the correct answer is 'Glucose and amino acids'.
  • Question 5
    1 / -0
    Correct sequence of arrangement of segments in the leg of cockroach is
    Solution
    In cockroach, three pairs of legs, are substantially different in lengths and functions, but they have the same parts and move the same way. The upper portion of the leg, called the coxa, attaches the leg to the thorax. 
    The trochanter acts like a knee and lets the cockroach bend its leg.
    The femur and tibia resemble thigh and shin bones.
    The segmented tarsus acts like an ankle and foot. The hook-like tarsus also helps cockroaches climb walls and walk upside down on ceilings.
    So the correct answer is 'Coxa, trochanter, femur, tibia, and tarsus'.

  • Question 6
    1 / -0
    In Cockroach, gizzard is part of
    Solution
     The digestive system of cockroach consists of the pharynx, the esophagus, the crop, the intestine, and the gizzard.  After the food passes through the esophagus, the food moves into the crop where it is stored and then eventually moves into the gizzard. The gizzard uses stones that the earthworm eats to grind the food completely. The food moves into the intestines as gland cells in the intestine release fluids to aid in the digestive process.
    So the correct answer is 'Digestive system'.

  • Question 7
    1 / -0
    Correct statement about circulatory system of cockroach is
    Solution
    The heart of the cockroach is elongated, thick, muscular, tubular and 13-chambered. It lies in the pericardial sinus of the hemocoel. Each chamber of the heart receives oxygenated blood from the dorsal sinus through one pair of slit-like openings called ostia. The heart contracts in a posteroanterior direction and the blood also flows posteroanterior. The alary muscles are responsible for the circulation of blood.

    So the correct answer is 'It has a 13-chambered heart with a pair of ostia in each chamber'.
  • Question 8
    1 / -0
    Number of spiracles found in Cockroach are
    Solution
    In cockroach, the respiratory system has a network of the trachea. They open through 10 pairs of spiracles that are present on the lateral side of the body. Thin tubes carry oxygen from the air to all the parts of the body. The spiracles are regulated by the sphincters. Exchange of gases takes place by diffusion.
    These are organized as 2 pairs of thoracic spiracles and 8 pairs of abdominal spiracles.
    So the correct answer is '2 thoracic, 8 abdominal'. 

  • Question 9
    1 / -0
    Adhesive pads present in legs of Cockroach are
    Solution
    The adhesive pads are present at the tip of each tarsal segment in cockroaches. These help them while climbing smooth surfaces. These adhesive pads are called plantulae.
    So, the correct answer is 'Plantulae'.
  • Question 10
    1 / -0
    In Earthworm, typhlosole occurs between
    Solution
    A pair of short and conical intestinal caecae projects from the intestine on the 26th segment. The characteristic feature of the intestine is the presence of an internal median fold of dorsal wall of the intestine called typhlosole between the 26th and 95th segments. This increases an effective area of absorption after digestion.
    So the correct answer is '26th -95th segments.
