Answer:
People drink water that has been contaminated by animal feces
Explanation:
Given the characteristics mentioned in the question, the animal must be an annelid.
<h3>What is an annelid?</h3>
Annelids, (Phylum name annelida) segmented worms, characterized by having body cavities (or body coelom), mobile bristles (or setae), and bodies segmented by transverse rings. The body cavity is reduced in leeches, and the bristles are devoid of some specialized morphology, including leeches. An important phylum of invertebrates in the animal kingdom, Annelida, consists of more than 9,000 species divided into three classes: Sea worms (polychaetes) are divided into motile and sedentary or tube-dwelling forms. earthworms (Oligochaeta); and leeches (Hildinea). Annelids are coelomic and tridermal.
General characteristics of annelids are:
- They show organization at the organ system level.
- Your body is segmented.
- They breathe through their body surfaces.
- The kidney is an excretory organ. They have well-developed circulatory and digestive systems.
- Common names for more familiar annelids include earthworms, sandworms, annelids, bristleworms, and leeches.

Answer:
64
Explanation:
Since the population is in Hardy-Weinberg equilibrium and the equilibrium is defined by the equation
p² + 2pq + q²
where the frequency of the homozygous dominant allele F ( feathers on the leg ) = p²,
F of homozygous ( featherless legs) = q²
F of heterogyous ( carrier of featherless allele) = 2pq
F (q²) = 128/200 = 0.64
q = √0.64 = 0.8
and p + q = 1
p = 1 - 0.8 = 0.2
2pq = 2 × 0.2 × 0.8 = 0.32
number of chickens that are heterozgous for the feathered leg allele = 0.32 × 200 = 64
