A Correct answer
Explanation

Yes, it is correct. Organs which have different design but serve a common function in different animals are called analogous organs. Wings of bats are mainly composed of the digital bones and a thin membrane covering the structure. Yet, wings in both the organisms are used for flying.

Multiple choice

Moldy fungi differ from the slime molds in:

  1. possessing basidiospore

  2. producing amoeboid or flagellated cells

  3. being heterotrophic

  4. having different cellular organisation

  5. there is no difference
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Moldy fungi are absorptive heterotrophs, whereas the slime molds perform phagocytosis, a process in which they engulf their food and get it digested through different enzymes.
