Answer:

A, B, C

Explanation:

Freshwater wetlands are defined as the lands which have natural supply of water for the whole season due to geological or ecological factors such as  tidal flows, connections with groundwater or  flooding rivers.

There are three main types of freshwater wetlands swamp, marsh and bog.

A Swamp are able to support tall shrubs, tress, herbs and mosses to grow . These are covered with floodd water or gently flowing water and  waterlogged soils prevent woody debris to decompose completely.

Marsh is found near lake, tidal water or rivers and remain flooded periodically. Marsh are the grassy areas covered by shallow water and help to overgrown with coarse grasses, rushes and sedges.

Bog is defined as an area where moss or mots decomposes slowly and form peat . They are characterized by acidic waters, a floor covered by a thick carpet of sphagnum moss and spongy peat deposits. they are generally found in northern climates which support precipitation of water.

Hence, the correct answer is A, B, C.

Gray seed color in peas is dominant to white. Assume that Mendel conducted a series of experiments where plants with gray seeds
bazaltina [42]

Answer:

(a) Gg × Gg; (b) genotypic = 1:2:1, phenotypic = 3:1

Explanation:

a) A cross between two gray seeded plants produces progeny with gray and white seeds in 3:1 ratio (302:98=3:1). This means that the parent plants are heterozygous and each has at least one recessive allele. If the allele "G" is responsible for gray seed and the allele "g" imparts white color to the seeds, the genotype of the heterozygous parents would be "Gg".  

b) A cross between two heterozygous gray seeded parents would produce progeny in following ratio:

Genotype ratio= 1 GG: 2 Gg: 1 gg

Phenotype ratio= 3 Gray: 1 white
