Answer:
spleen is a correct answer.
Explanation:
Foreign particles circulating in the blood are filtered by the spleen
Spleen is present in the upper left area of the abdomen.
Spleen function is to filter the foreign particles from the blood as it acts as a blood filter.
Spleen recognizes the damage and old red blood cells, foreign particles.
As the blood flows into the spleen the white blood cell present remove and they attack the foreign particles.
Spleen acts as a blood filter by this way foreign particle are removed and the blood is filtered.
Thus(spleen) is a correct answer.
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.

Answer:
A) action and myosin sliding past each other and partially overlapping
Explanation:
The muscle contraction occurs by the interaction between two protein filaments in sarcomeres (actin and myosin). During this process there is a “shortening” of the sarcomere, caused not by changing the length of the actin and myosin filaments, but by overlapping these filaments,
