The <u>urethra</u> is an organ which communicates with the lower bladder in order to enable excretion of urine from the body of a living organism.
<h3>What is an excretory system?</h3>
An excretory system refers to a living system that is saddled with the responsibility of removing waste products from the body of a living organism, so as to prevent damage to the body and help maintain homeostasis.
Based on scientific information, the <u>urethra</u> is an organ which communicates with the lower bladder in order to enable excretion of urine from the body of a living organism.

Answer:
It recognizes and binds to a pair of "mismatched" nucleotides, preventing their translation.
Explanation:
Mut L protein is involved in mismatch DNA repair. MutL protein is complexed with MutS protein and the MutL-MutS complex recognizes all the mismatched base pairs present in the newly formed DNA strand. The complex can not recognize the "C-C" pairs. MutH protein joins the complex.
The MutH protein also has a site-specific endonuclease activity and cleaves the unmethylated DNA strand towards the 5' end of the guanine base in the GATC sequence to mark the strand for DNA repair. In this way, MutL protein, along with MutS and MutH proteins mark the mismatched DNA bases for repair so that they are not translated into a faulty protein.
Answer:
Factors that remain constant from experiment to experiment are the constants.
Explanation:
A constant in an experiment is also known as a <em>control variable</em>. It is the part of an experiment that must stay the same in order to validate the experiment. If the constant were to change, the results would be skewed and therefore false.
i.e. you want to test the rate of growth of lima bean plants in different types of lighting. You believe that a lima bean plant that grows in yellow will grow faster and stronger than a lima bean plant that grows in blue or red light.
In this experiment, the constant would be the lima bean plant. You cannot change the type of seed or else your experiment is invalidated. If you tried to use a sunflower seed in the blue lighting and a tomato seed in the red lighting, your results would be invalidated and skewed.
Answer:
Cytokinesis
Explanation:
After meiosis I finishes, the cell splits in a period called cytokinesis. Each cell then has half the original number of chromosomes.
