couple of bio questions

[pistolpete007]

whats the difference b/w releaser phermone and sex phermone. also on destroyer 185:
A. chemical that tavels outside the body, carrying info to members of the same species-AGGREGATION PHERMONE?
Bthey may act as sex attractants- is this sex phermone or releaser?
c.Fromic acid produced by ants is an example of a Trail phermone?
D.Many vertebrates use pheromones in feces, urine or scet glands to mark territories....territorial phermone

If an organism has a diploid number 18, how many chromatids are visible at the end of mitotiic prophase, mitotic telophase, meisois prophase I, meiosis telophase I, meiosis prohase II, and meiosis telophase II respectively?

I will answer the second question...end of mitotic prophase=36, mitotic telophase=18 (if you are refering to a single cell, each has 18), meiosis prophase I=36, meiosis telophase I=18, meiosis prophase II=18, meiosis telophase II=9

1 sister chromatid = 2 chromatids
1 chromosome = 1 or 2 chromatids = 2 sister chromatids

I put 1 or 2 chromatids because during prophase I when you have a homologous chromosome and 2 chromatids it is 1 chromosome but after they seperate completely during anaphase II you will still have 1 chromosome with 1 chromatid...

as far as I know, there isnt much of diff between releaser phermones and sex phermones. They both kinda of do all mention facts that you said.
