    Thank you for asking our help with your homework assignment. However, there are some rules we have for doing so.
    Do not simply retype or paste a question from your book or study material

    We won't do your homework questions for you. You were given the assignment for you to learn.

    If you come up with your own answer or process and post it for us to critique that is acceptable. If you have some SPECIFIC questions that you couldn't find or didn't understand, we may help with that.
    But this is your assignment, so show us you have at least attempted to complete it on your own.

    Thank you.

    Which of the following transport show that plasma membrane is elastic nature?
    1)osmosis
    2)diffusion
    3)endocytosis
    4)active transport
    The answer is 3 but how?why not the others?all are related to plasma membrane and its selectively permeable nature.all allows certain solutes to pass through it so why 3?

    Which of the following is a function of basement membrane and how explain the answer?
    1)contractility
    2)molecular filtering
    3)active ion transport
    4)excitability
    The answer is 2 but basement membrane also helps in active ion transport so why it can't be 3?

    Biology of class 11th plant diversity
    What is hierarchy and explain the answer how?
    1)history of evolution of plants
    2)numerical classification
    3)descending order of taxonomic categories
    4)empirical classification
    The answer is 1 but history of evolution of plants is known as phylogeny and hierarchy is the descending order of taxonomic categories.so answer should be 3 but in book it is given 1.
