Answer:
The dura mater and pleural contain fluid which lubricates the brain and lungs respectively.
Explanation:
Dura mater is the outermost layer and a sac in the brain that envelope arachinoid and it's surrond venous channels which carried blood from the brain to the heart. The dura mater contain cerebrospinal fluid and drains it from the brain to the internal jugular vein
The pleural help in the proper functioning of the lungs and it supply pleural fluid which lubricates the lungs and allow for respiration.
The answer is isokinetic exercise. This type of exercise <span>uses specialized exercise machines that produce a constant speed no matter how much effort you expend and</span> allows muscles to gain strength consistently all through the range of movement. Isokinetic exercises are often used for rehabilitation and recovery since it’s a controlled form of exercise.
Answer:
Plants take in carbon and let out oxygen.
Explanation:
Carbon and cellular respiration has to do with those cycles because plants which do cellular respiration as well as all living things take in either oxygen or carbon and let either one of them out.
The right answers are:
A-present in eukaryotic genomes ==> Both exons and introns
B-generally absent from bacterial genomes ==> Introns
C-part of the final mRNA strand ==> Exons
D-code for an amino acid sequence ==> Exons
E-removed from initial mRNA strand prior to translation ==> Introns
F-present in the DNA used as the template for transcription ==> Both exons and introns
In the genes of eukaryotic organisms, the exons are the segments of an RNA precursor that are conserved in the RNA after splicing and that are found in mature RNA in the cytoplasm. The segments of the RNA precursor that are removed during splicing are called in opposition to introns. Exons are mainly found in messenger RNAs (mRNAs) encoding proteins. Some mRNAs may sometimes undergo an alternative splicing process in which one or more exons may be excised or some introns preserved in rare cases.
