Anammox (anaerobic ammonium oxidation), which is a reaction that oxidises ammonium to di-nitrogen gas using nitrite as the electron acceptor under anoxic conditions, was an important discovery in the nitrogen cycle.

Suppose a population of flour beetles has 10,000 individuals. There are two alleles possible for the gene that determines body c

miss Akunina [59]

Answer:

$0.75$

Explanation:

Given frequency of the two alleles i.e "B" and "b" are equal .

As per Hardy–Weinberg equilibrium, sum of frequency of the two alleles is equal to one.

i.e $p+ q= 1\\$

Since $p=q\\$

$p$ and $q$ will be equal to 0.5

Frequency of genotype "BB"

$= p^{2} \\= 0.5^{2} \\= 0.25$

Frequency of genotype "bb"

$= q^{2} \\= 0.5^{2} \\= 0.25$

As per second equation of Hardy–Weinberg equilibrium,

$p^{2} + q^{2} + 2pq=1$

Substituting the values of p and q in above equation we get -

$0.25+0.25+2pq=1\\2pq = 1-0.25-0.25\\2pq = 0.5$

Red beetles have genotype BB and Bb

number of red beetles with genotype (BB)

$= 0.25 * 10000\\= 2500$

number of red beetles with genotype (BB)

$= 0.5 * 10000\\= 5000$

Total red beetles

$2500+ 5000= 7500\\$

Frequency of red beetles

$= \frac{7500}{10000} \\= 0.75$

5. Knowing the type of food consumed by an organism helps to

Romashka [77]

This role would be the organisms niche. None of the other choices make any sense. A nesting site is not a role, a biomass is not a role, and territorial range is not the role an animal has in its community. A niche is an organisms role in its community, how it interacts with the things around it, where it lives and what it does.
