Except for the first and last segments, which have no setae, there are eight tiny bristle-like structures that can not be seen with the naked eye called setae on each segment of an earthworm. The arrangement of the setae is one factor that helps in the identification of earthworms, as they can be closely or widely paired in four pairs or separate. Setae grip the soil to help the earthworm move about and sense the enviroment.
What else can I help you with?
How many amino acids are produced by the segment of DNA that has 21 bases?
A segment of DNA with 21 bases would encode for a polypeptide with 7 amino acids. This is because each amino acid is coded for by a sequence of three bases, called a codon. Therefore, 21 bases would be translated into 7 codons, each specifying an amino acid.
How many base pairs are present in this segment of DNA Model?
To determine the number of base pairs in a segment of DNA, you would need to know the length of the segment in base pairs. Each base pair consists of two nucleotides bonded together, such as adenine-thymine or cytosine-guanine. You can count the bases in the segment and divide by two to get the number of base pairs.
Does the number of segments on a earthworm relate to its age?
Yes, because worms grow by adding segments to their posterior end. While many species grow to a length of only a few centimeters, some tropical species live for up to ten years and grow to a length of more than 3 meters.
How are nutrients transported from the blood of an earthworm to the muscle cells of its body wall?
Nutrients are absorbed by the earthworm's digestive system from the ingested soil and transported by the circulatory system in the blood. The circulatory system consists of blood vessels that deliver these nutrients to all body tissues, including the muscle cells in the body wall. Once in the muscle cells, nutrients are utilized for energy production and other cellular processes.
During replication which sequence of nucleotides would pair with the DNA segment ttacgc?
The DNA segment ttacgc would pair with the complementary RNA sequence aaugcg during replication. In RNA, adenine (A) pairs with uracil (U) instead of thymine (T).
How many pores are there in each segment of an earthworm?
2
How many segments does a earthworm have?
In an adult worm, there may be more than 100 segments.
How many parapodia are found per segment in earthworm?
Earthworms do not have parapodia.
How many setaes on one earth worms segment?
they have 4 of them on each segment
How many endpoints does a segment have-?
Just the two of them at each end of the line segment.
What are the two specific points of a line segment?
Any line segment has infinitely many points and each one of them is specific to that line segment.
Who many eyes does an earthworm have?
An earthworm has 5 eyes, that your answer!!!
How do you describe segmentation in earthworms?
The earthworm is a segmented worm with a true coelom which is partitioned into separate segments. There are many internal structures that are repeated within each segment. Each segment is surrounded by both longitudinal and circular muscles allowing earthworms coordinated movement. The fluid filled coelom acts as a hydrostatic skeleton. Each body segment contains four pairs of chaetae, bristles that provide traction for movement. Also the first four segments make up the anterior head region of the external structure of earthworms. The first segment is the periostomium which bears the mouth and the anus is found in the last posterior segment. My reference is my Biology 191 laboratory manual on invertebrates. (pg's 77-78)
How many setae are on a worm?
The earthworms has 4 seate's on each segment.
Earthworm B is how many centimeters longer than Earthworm A?
It is seven (7) centimeters.
How many times does each line segment in a polygon intersect?
I want to say 2, once at each corner
How many septum do earthworm's have?
