BIOLOGY: CARDIOVASCULAR 6 Cardiovascular Cardiovascular Introduction Some of the significant differences between smooth muscle and skeletal muscle occur during the excitation-contraction coupling (Weckström & Tavi, 2007). Additionally, one fundamental similarity between the two muscles is the existence of calcium which plays a significant starring role (Gurji, 2005). However smooth muscles

Cane Toads

6CANE TOADS Cane Toads Cane Toads Cane Toads (Buffo marinus) are native species in Australia (Koike, 2006). They are very hardy and voracious predators of small prey such as insects. Because of this reason, they were introduced into Australia from their original land of Hawaii in order to control pest

The role of amino acid nanoparticles in Arthritis

The role of amino acids nanoparticles in Arthritis Role of amino acids in arthritis Arthritis is a medical condition that affects the bones and the joints. Arthritics causes the cartilage of a person’s joint to wear out which leads to thinning of the cartilage and in turn causes friction, inflammation,


Dear customer, Please find your document in the second attachment. Thank you.

Part 3: (i)

According to the figure, the single stranded loops present in the double stranded nucleic acid represent the introns. The loop structures are formed following splicing in the post-transcription stage. Basing on this information, there are eight introns in the gene. From available literature, the universally conserved nucleotides in the 5′

Summary of Article: How cells know the size of their organs

Summary Of Article University affiliation Reasons as to why Cells are cautious regarding the size of their organelles. Mostly, the cells occupy fixed volumes. The reactions within the cells, as well as the pathways, are subdivided within the distinct cytoplasm and organelles, which have a definite size. Therefore, at least

SECTION A: 4). When placed in different solutions, the cells react differently due to osmosis. In distilled water, the animal cell would absorb water and explode. This is similar to the plant cell. However, the plant cell does not explode due to the nature of its cell cover. Therefore, the


Discuss sepsis in humans due to infection with Gram negative bacteria such as Escherichia coli? The outer cell wall of Gram negative bacteria is made up of endotoxins occupying at least three quarters of the cell wall membrane. Endotoxins are glycolipid lipopolysacharide (LPS) molecules capable of causing lethal shock. The
