    The pancreas secretes digestive enzymes and bicarbonate into the small intestine.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The pancreas is an important organ involved in digestion. It produces and secretes digestive enzymes such as amylase, lipase, and protease, which help break down carbohydrates, fats, and proteins respectively. These enzymes are released into the small intestine to aid in the digestion of food. Additionally, the pancreas also secretes bicarbonate, which helps neutralize the acidity of stomach acid as it enters the small intestine. Therefore, it is true that the pancreas secretes digestive enzymes and bicarbonate into the small intestine.

    • Fimbriae

    • Corpus luteum

    • Follicles

    • Oocytes

    Correct Answer
    A. Oocytes
    Explanation
    Fimbriae are fingerlike projections at the open end of the oviduct that help move the oocyte into the oviduct.

    Corpus luteum are the remains of the ruptured follicle that secretes large amounts of progesterone and estrogen to prepare the uterus for the possible arrival of a fertilized egg.

    A follicle is a primary oocyte and its surrounding nourishing granulosa cells.

    An Oocyte is an immature egg cell.

    Rate this question:

  • 10. 

    Primary oocytes are present in females at birth.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Primary oocytes are present in females at birth. These primary oocytes are immature eggs that have not yet undergone meiosis. They are arrested in prophase I of meiosis and remain in this state until puberty. At puberty, a small number of primary oocytes are activated each month to continue meiosis and develop into mature eggs. Therefore, it is true that primary oocytes are present in females at birth.

    Rate this question:

    What is usually the cause of death from cancer?

    • Neoplasms

    • Benign tumors

    • Metastasis

    • T-cell failure

    Correct Answer
    A. Metastasis
    Explanation
    Metastasis is the correct answer because it refers to the spread of cancer cells from the original site to other parts of the body, leading to the formation of secondary tumors. This process is responsible for the majority of cancer-related deaths, as it allows cancer cells to invade and damage vital organs and tissues. Neoplasms and benign tumors are not the cause of death from cancer, as they can often be successfully treated or removed. T-cell failure, while it can weaken the immune system and increase the risk of cancer, is not the direct cause of death.

    Correct Answer
    A. Interphase
    Explanation
    Mitotic phase is the entire process of the nucleus and then the cytoplasm dividing.

    Prophase is the first phase of mitosis. (During prophase the chromosomes condense and thicken, the pairs of centrioles migrate to opposite sides of the cell, and the mitotic spindle forms which is the structure that causes the two identical strands of DNA to divide.)

    Cytokinesis is when the cytoplasm divides and two new cells (called daughter cells) are formed.

    Interphase is the long growth period that is divided into the above three subphases.
