Answer:
The correct answer will be-
1. Nucleosomes
2. Chromatin
3. Sister chroamtid
4. Centromere
Explanation:
The DNA is a very long molecule which if has to be passed on to the daughter cell as it is will cause problems. So, to reduce problems a cell form tightly packed structure of DNA so that they can be passed easily to the daughter cell.
The packaging of DNA begins with the wrapping of the DNA around histone proteins which forms the 11 nm basic structural units called nucleosomes. The nucleosomes start condensing each other and form 30 nm structure chromatin fibres.
The chromatin fibres undergo replication during S phase which produces an exact copy of the chromatin called sister chromatids bound to each other at a central point called centromere which helps the separation of the chromatids during M phase.
Answer:
Characteristics of Fungi
Fungi are eukaryotic, non-vascular, non-motile and heterotrophic organisms.
They may be unicellular or filamentous.
They reproduce by means of spores.
Fungi exhibit the phenomenon of alternation of generation.
Fungi lack chlorophyll and hence cannot perform photosynthesis.
The right answer is: C) Iruptive Growth. For their growth is never stable.
bro this is so easy,
if to animals fight, the one more adapted, prepared or psychically built will win will the weaker one lose and die, which is natural selection at its finest.
