Answer:
The correct answer is a) It brings a transport liquid into close contact with all cells in the body.
Explanation:
The circulatory system helps in bringing the blood which is a transport liquid in close contact with the cells present in our body. This helps in gas exchange between cells and blood. The circulation of blood in the body occurs by the pumping of blood by the heart into arteries, veins, and capillaries.
This circulation of blood plays many other vital functions like transport of nutrients to the cells, transport of waste products from the cell to outside the body, transport of hormones, maintenance of body temperature, etc.
So all these processes become possible when transport liquid comes in contact with the cells. Therefore the right answer is a.

Answer:
43 monosaccharides will be joined together to make the complex carbohydrate.
Explanation:
The complex carbohydrates are synthesized by the joining of monosaccharide residues by glycosidic linkages.One glycosidic linkage joins two monosaccharide residues by the elimination of one molecule of water.
In other words it can be said that elimination of one water molecule joins two monosaccharides.By the same way elimination of 42 molecules of water will result in the joining of 43 monosaccaride residues.
<span>Pressure waves originate within the inner ear at the oval window and travel through the perilymph in the scala vestibuli. Pressure waves in this structure cause deformation of the cochlear duct. The pressure waves then displace specific regions of the basilar membrane, relating to frequency. Hair cells in the cochlea of this region are distorted, initiating nerve signals in the cochlear branch of cn viii.</span>
