Strains fuse nuclei and produce a in sexual reproduction, two different strains of hyphae called <u>plus</u> and <u>minus</u> zygote.
Explanation:
In a fungi or rhizopus, sexual reproduction takes place by fusion of a plus and minus strains. As the hyphae grows in these opposite strains, they become close together due to swelling, and come into contact with each other.
These plus and minus strains of nuclei travel into these swelling and forms the progametangia. This then converts to gametangia which dissolve and fertilze and produce diploid zygote nuclei.
A zygosphere covers these nuclei which later undergoes meiosis and forms hyphae with sporangium filled with haploid spores.
The correct answer is true. Both intramembranous ossification and endochondral ossification originates from a primary ossification center. The primary ossification center, as the name implies, is the focus where the bone tissue starts ossifying. Primary ossification centers are usually found in the diaphysis of long bones or in the body of irregular bones.
Variation - different appearance and behavior
inheritance- traits passed on from parent to offspring
growth in population
and survival and reproduction
