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.

nevsk [136]
Protein synthesis occurs in the cytoplasm, specifically in the ribosomes. Proteins that are meant to be excreted, such as in the pancreas, are produced in the rough endoplasmic reticulum which is a membrane studded with ribosomes. In organs that primarily function to produce and secrete proteins, there will be a larger rough endoplasmic reticulum with more ribosomes.

A client diagnosed with scabies has been prescribed lindane lotion.
AfilCa [17]

Answer:

Answer is E. Apply a thin layer of lotion on the skin from the neck to the soles of the feet.

Scabies are described or known to be small bugs that burrow and  found crawling under the skin. They lay eggs and continue to multiply under the skin.

They cause rash on the skin and severe or intense itching, which normally get worse in the night.

The lindane lotion , when applied on the skin, goes through or enters the skin, and kills the scabies and their eggs.

The scabies do not affect the face of adults and older children.

Pepsi [2]

Answer:

<em>As scientists learned more about genetics and biochemistry , some organisms were moved out of existing kingdoms and into new ones.</em>

Explanation:

As the researches in the scientific world continued, scientists realized that there were, in fact, many genetic diversities present in organisms which were placed in the same groups. Hence, they realized that due to these differences these organisms should not be kept in the same group. As a result, the groups in the classification system increased.

Carolus Linnaeus just grouped organisms based on their features. But today, scientists classify organisms based on various perspectives such as the evolutionary history, genetic similarities etc.
