    What is venous heart?

    <p>A venous heart is a heart that receives deoxygenated blood from the body and pumps it to the lungs for oxygenation. This type of heart is found in some invertebrates, like mollusks.</p> Signup and view all the answers

    Explain the term viviparous.

    <p>Viviparous animals give birth to live young ones, rather than laying eggs. The embryos develop inside the mother's body, receiving nourishment through the placenta or yolk sac.</p> Signup and view all the answers

    What is adelphy?

    <p>Adelphy refers to the fusion of stamens, the male reproductive parts of a flower, into a single group or bundle. This fusion can occur completely or partially, resulting in different patterns of stamen arrangement within the flower.</p> Signup and view all the answers
