Answer:

Lakes and rivers

Explanation:

Lago is the name used to designate a naturally formed depression that constantly stores a large amount of water. The water contained in a lake can have several origins, such as: own spring, rainwater, salt water from ancient seas, rivers and melting glaciers. The salt concentration in the lakes is greater than the concentration that allows the tench fish to survive. The same happens with the concentration of salt in rivers.

A river is a watercourse that flows naturally from a higher area to a lower one of the relief, usually flows into another river, lake or sea. These water courses are formed from rain, which is absorbed by the soil until it reaches impermeable areas in the subsoil where it accumulates, constituting what we call groundwater.

Brown coat color rabbits possess the dominant allele B, and white coat color rabbits possess the recessive allele b. If the freq
PolarNik [594]

Assuming Hardy-Weinberg equilbrium, we have

p + q = 1

where p = frequency of dominant allele and q = frequency of recessive allele. So

p = 1 - q = 1 - 0.04 = 0.96

Consequently we have

• p² = 0.9216 = frequency of hom ozygous domininant genotype

• pq = 0.0768 = frequency of heterozygous genotype

• q² = 0.0016 = frequency of hom ozygous recessive genotype

since

p² + 2pq + q² = 1

A species whose presence is critical to maintaining the ecological balance is called a/an _____ species.
kow [346]

Answer:

keystone species

Explanation:

Keystone species are indispensable species that are essential to the maintaining of the balance of an ecosystem, and also play a major role in the way species in the ecosystem interrelate. The absence or removal of a keystone species from a habitat or ecosystem would lead to the disruption and imbalance of the ecosystem, and as such lead to the extinction of other species.

An example of a keystone species is the bee. Bees are very important in pollination of flowering plants and also ensure their survival. This plants serve as home to various insects that are source of food to birds. The removal of bees from this ecosystem would affect the ecological balance of this ecosystem.
