Delta can also be an easy answer plus it is easy to remember
Answer:
Invasive species are among the leading threats to native wildlife. Approximately 42 percent of threatened or endangered species are at risk due to invasive species. These species were brout from other countries and they cause problems in these other countries or continents. Like the bees in america were not native and neither werer the cattle in the western hemisphere.
Explanation:
Answer:
collecting duct
Explanation:
The collecting duct is part of nephrons and has mainly two types of cells. These are called principal cells and intercalated cells. The principal cells of collecting duct have receptors for ADH and aldosterone. The function of the anti-diuretic hormone (ADH) is to reduce the fluid loss from the body when blood volume and blood pressure fall and the person experiences dehydration. In response to ADH, transcytosis of water in collecting duct is stimulated. This results in the absorption of most of the water from the filtrate and formation of concentrated urine.
Answer:
The answer is incomplete because it is imperative to know what is the result of the transposition (i.e., deleterious, beneficial or neutral). For example, A and C options represent study cases where the insertion of Transposable Elements (TEs) may result beneficial for the organism.
Explanation:
Transposable Elements (TE) are mobile genetic elements that have the ability to move within the genome. According to their mechanisms of insertion, TEs are classified into two major classes: Class I (or retrotransposons) and Class II (DNA transposons), which are capable of moving by copy-paste (i.e., by a RNA intermediate) and cut-paste mechanisms, respectively.
Although originally were considered to be parasitic (deleterious) genetic mobile elements, nowadays it is well known that they may be sometimes beneficial depending on the localization of the TE insertion. For example, TE insertion into a protein-coding region (exon) sequence it is likely to produce protein disruption and thereby it has a deleterious effect. However, the insertion of TEs into upstream and intron non-coding regions may confer gene regulatory activity and be eventually beneficial to the organism.
