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:
B) A difference in pressure across a distance.
Answer:
Topoisomerase and Primase
Explanation:
Topoisomerase — Relaxes the super-coiled DNA
Primase — Provides the starting point for DNA polymerase to begin synthesis of the new strand
In the apple maggot fly, the frequency of certain alleles increases steadily as one goes from North to South. This is an example of: Sympatric speciation.
Sympatric speciation is observed when there are no physical barriers which prevent any members of a species from mating with another, and all members are in close contact to one another. A new species, possibly established on a distinct food source or trait seems to develop instinctively.
The example of apple maggot fly supports a model for sympatric speciation in progress. Hawthorn is the native host for the apple maggot fly in North America. However, in the mid-1800s, a new population developed on introduced, domesticated apple.

Answer:
Water has several very unique properties, like surface tension, cohesion, and adhesion because water is polar and every water molecule electrically attracts the neighboring water molecules.
Explanation:
Water is a universal solvent and has several unique properties like surface tension, adhesion, cohesion, high specific heat, etc.
In a water molecule, the oxygen atom's nucleus attracts electrons more strongly than the nuclei of hydrogen atoms. The negatively charged electrons are pulled toward the oxygen atom's nucleus and away from the hydrogen atom nuclei. As a result, a negative electrical charge occurs in the middle part of the water molecule near the oxygen atom and a positive charge near the other parts of the molecule (hydrogen atoms). This unequal distribution of electrical charge between different parts of the water molecule (polarity) makes it a polar molecule.
The positive part of one water molecule (hydrogen atoms) is attracted to the negative parts of neighboring water molecules and as a result, hydrogen bonds are formed between hydrogen and oxygen atoms of adjacent water molecules. These hydrogen bonds between molecules help hold water molecules together.
