SPINDLE FIBERS
In Mitosis, Spindle Fibres form at opposite poles of the cell and meet at the equator. Collectively, they form a spindle-shaped structure which attach to Centromeres.
CENTROSOMES
The organelle located near the nucleus in the cytoplasm,
composed of 2 centrioles that divides during S Phase
Centrioles are surrounded by a mass of proteins (Pericentriolar Material (PCM))
Migrates to opposite poles of the cell during mitosis
Involved in the creation of spindle fibres
CHROMOSOMES
A threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes.
Centromeres
The constricted region joining the two sister chromatids that make up an X-shaped chromosome. It also serves as the point of attachment for spindle fibers when the spindle fibers are pulling the chromosomes toward the centrioles (situated on opposite poles in a cell) prior to cytokinesis.
Answer:
Fats: fatty acids and glycerol
Protein: amino acids
The similarities are;
- Both of them depend on light to function
- Both of them could be adjusted during studies
- The object could be magnified or diminished during study.
<h3>What is SI V-Scope?</h3>
The SI V-Scope is a sort of a virtual microscope that is designed to operate in a manner that is similar to that of the compound light microscope. The both tools could be used for investigation.
Recall that a microscope is a device that could be used to see a very small specimen. The first microscope was the compound microscope and was invented by Robert Hooke. This microscope was used to observe the cells of cork.
The following are the similarities between compound light microscope and SI V-Scope;
Both of them depend on light to function
Both of them could be adjusted during studies
The object could be magnified or diminished during study.

THE EXCRETORY SYSTEM
Answer: The attachment shows the nephron which is the functional unit of the kidney.
It does the work of urine formation through 3 distinct processes.
-Ultra filtration( Small molecules are forced out of the selectively permeable membrane of the glomerulus into the Bowman's capsule under regulated pressure.these molecules are from the blood in the glomerulus brought in by the afferent arteriole.
- Selective reabsorption ( Useful molecule and iron such as glucose and sodium are reabsorbed back into the blood as the filtrate flows through the tubule(nephron)
-Tubular Secretion. ( Movement of molecules not filtered by the glomerulus during the initial stage of filtration back into the filtrate through the renal capillaries.
Stella's urine sample shows the presence of large protein (ULTRAFILTRATION)
John's blood test report indicates a high toxin level ( ULTRAFILTRATION AND TUBULAR SECRETION)
Miguel's blood test shows an increase in metabolic waste( ULTRAFILTRATION AND TUBULAR SECRETION)
Janice's urine report shows the presence of vital materials ( SELECTIVE REABSORPTION).
