    Glands in a vertebrate body originate from

    • ectoderm, mesoderm and endoderm

    • ectoderm and endoderm

    • mesoderm

    • ectoderm

    D.

    ectoderm

    Glands in a vertebrate body originate from ectoderm. Glands are the modification of epidermis of skin. The ectoderm also gives rise to the neural crest (ganglion, sensory cell, etc) and neural tube (brain, spinal cord etc).

    3.

    Function of SER is

    • protein metabolism

    • lipid metabolism

    • carbohydrate metabolism

    • catabolic activity

    B.

    lipid metabolism

    SER or Smooth Endoplasmic Reticulum is an organelle present in both animals as well as plants. The function of SER is lipid metabolism. It does not contain ribosomes and is specialised to synthesize lipids and steroids.

    RER or Rough Endoplasmic Reticulum is attached with ribosomes on its surface and its main function is in protein synthesis.

    • Annelida and Arthropoda

    • Annelida and Mollusca

    • reptiles and mammals

    D.

    reptiles and mammals

    Ornithorhynchus is a connecting link between reptiles and mammals. They bear hair and mammary glands (like-mammals), but also possess some of the reptilian characteristics such as egg laying, presence of cloaca and some skeletal similarities.

    Patella (knee cap) is an example of

    • replacing bones

    • sesamoid bones

    • flat bones

    • irregular bones

    B.

    sesamoid bones

    Sesamoid bones are small rounded masses of bones formed in tendons at the joints, where they are subjected to great pressure. e.g., patella, fabellae.

    Which of the following branch of biology is correctly matched?

    • Ornithology - Study of mammals

    • Herpetalogy - Study of molluscs

    • Ophiology - Study of snakes

    • Therology - Study of birds

    C.

    Ophiology - Study of snakes

    Ophiology is the branch of zoology that deals with snales.

    Ornithology is a branch of zoology that concerns the study of birds. 

    Herpetology is the branch of zoology concerned with the study of amphibians and reptiles.

    Therology is the study or science of mammals.

    Malacology is the branch of zoology that deals with molluscs.

    Answer

    Which of the following is correctly matched?

    • Enlarged P-wave - Acute myocardial infarction

    • QRS wave flat - Atherosclerotic heart disease

    • Enlarged Q and A - wave-Myocardial infarction

    • Elevated S-T - Enlargement of atria

    C.

    Enlarged Q and A - wave-Myocardial infarction

    Electrocardiography is the process of producing an electrocardiogram (ECG). It records the electrical activity of heart. It detects tiny electrical signals that make heart pump blood around the body.

    Enlarged Q and R waves indicates a myocardial infarction. The S-T segment is elevated in acute myocardial infarction and depressed when the heart muscle receives insufficient oxygen. Enlargement of the P-wave indicates enlargement of the atria. T-wave is flat when the heart muscles receive insufficient oxygen is in atherosclerotic heart disease.

    Which of the following helps in the absorption of Vitamin-B12?

    • Pepsin

    • Bile juice

    • Castle's intrinsic gastric factor

    • Cholecy stokinin

    C.

    Castle's intrinsic gastric factor
