The answer is a. the ureters. The ureter is a tube that
carries urine from the kidney to the urinary bladder. There are two ureters, the
upper half of the ureter is located in the abdomen and the lower half is
located in the pelvic area. One attached to each kidney.
Answer: Gene that arose through gene duplication, but by acquiring mutations became nonfunctional.
Explanation:
A gene is a functional unit of heredity formed by DNA. They possess a sequence of nitrogenous bases that during translation is read by ribosomes to produce molecules called proteins. A pseudogene is a DNA sequence that resembles a gene, but which has been inactivated in the course of evolution by mutations in its sequence. Thus, it is a gene that derives from other known genes and whose functions are different, <u>may have lost their functionality or have radically changed </u>it. To this day, it is not known exactly how pseudogenes are created, however some theories are as follows:
1. A gene duplication can generate two copies of a gene when only one is needed. A mutation would then occur that deactivates one of the copies. In addition, the duplication event may not be complete, so that the copy has incomplete promoters.
2. They may be fragments of the messenger RNA transcript of a gene may be spontaneously reverse transcribed and inserted into the chromosomal DNA. They lack the promoters of normal genes, so they are not expressed normally.
3. A gene may become non-functional or inactivated if such a mutation becomes fixed in the population. This can occur by normal means such as natural selection or genetic drift.
Your answer should be "Appears brighter than any other star" because the sun is brighter than the next brightest star in the sky.
Answer:
Bacteria that carried the traits for antimicrobial resistance were able to pass on the trait to their offspring
Explanation:
Populations of organisms that are able to be resistant to pesticides have acquired this due to the ability to properly breakdown the chemicals or package it and discard of it effectively.
Bacteria populations typically multiply very quickly and many mutations arise. Some of these mutations are fortunate adaptations to the very agent that is meant to kill them. These mutants that are able to survive antimicrobial treatment will be able to pass these on to their prodigy.
