Hydras may reproduce by budding. In this process, a small polyp forms on an adult hydra, and then it leaves to become a new organism. Which observation
would support the conclusion that budding is an example of asexual
reproduction?
a. The polyp that buds off the hydra has different DNA from the parent.
b. The polyp that buds off the hydra is significantly smaller than its parent.
c. Budding may occur in a hydra that has been completely isolated from others
of its kind,
d. Budding may occur in a hydra that has been raised with many others of its
kind

phaneritic textures in which phaner means visible so phaneritic textures are standard of impertinent volcanic rocks. these rocks crystallized gradually under the surface of earth. when the magma cools deliberately then the ores have chance to develop and produce long crystals.
