Answer:

Either through bacteria or lightning

Explanation:

Nitrogen can be converted directly to nitrates through lightning.

It can also be converted to ammonia (NH3) through free-living nitrogen fixing bacteria e.g <em>Azotobacter</em> or fixed on plants by symbiotic micro-organisms e.g <em>Rhizobium</em>. The Ammonia formed is converted to Nitrites (NO2) by nitrifying bacteria e.g <em>Nitrococcus</em> bacteria. The Nitrites are converted to nitrates by other nitrifying bacteria e.g<em> Nitrobactor</em>

Nitrification. The conversion of ammonium to nitrate is performed primarily by soil-living bacteria and other nitrifying bacteria. In the primary stage of nitrification, the oxidation of ammonium ( NH+4) is performed by bacteria such as the Nitrosomonas species, which converts ammonia to nitrites ( NO−2).

A woman with normal blood clotting ability whose father was a hemophiliac and whose mother was normal with no family history of
Alborosie

Answer:

The answer is 25%.

Explanation:

Hemophilia is a recessive illness that is x-linked.

If the husband has normal clotting ability, that means he has the dominant gene since he has only one X chromosome.

Since there is a probability that their child will have hemophilia, this means that the woman, who has 2 X chromosomes but has normal blood clotting abilities, has one dominant and one recessive hemophilia gene.

The probability that their first child will be a male is 50% and the probability that he will have hemophilia is also 50% since he will only get the Y chromosome from the father and the mother has one dominant and one recessive.

So the probability that their first child will be a son with hemophilia is 25%.

I hope this answer helps.
