Burj Khalifa is the world’s tallest building and was designed by Skidmore, Owings & Merrill architects, who have been bestowed with the “Global Icon” award. The design of the high-performance building makes use of cutting edge technology and carries cultural and historical influences. The architects faced several challenges when building a tower of this height such as wind, heat, humidity, gravity and earthquake forces.
The essay looks at the advanced technical and engineering skills used to create Burj Khalifa and how a skyscrapers’ design should respect cultural values and make the best use of space utilities and add to ...

C3 and C4 photosynthetic pathways

Plants have the ability to grown and survive in a number of different environments. They can adapt from hot and dry to frigid temperatures. In order to adapt to various environmental conditions plants have to adapt and develop mechanisms to survive different conditions. One mechanism of adaptation involves the mode of fixing carbon dioxide. Carbon fixation is the process of incorporating inorganic Carbon to an organic form. Photosynthesis is the process of carbon fixation used by the plants. C3 plants usually are found in cold, temperate climate and are most widely distributed worldwide. They use environmental carbon-dioxide (CO2) and incorporate ...

1. How does the basic leaf structure suit its function?
A leaf is a plant organ that is very crucial for a plant survival. It has a structure that makes it suitable to perform its functions. A leaf normally has a larger surface area so that they are able to absorb sunlight more easily. Sunlight is required by plants for the food making process. A leaf is normally very thin. This allows the carbon dioxide to travel and diffuse in a short distance. Also, oxygen which is usually a by-product, diffuse out easily. A leaf has a green coloring ...

The nervous system can be divided into two groups: the central nervous system (CNS), which comprises of the brain the spinal cord, and the peripheral nervous system (PNS), which consists of the nerves. Nervous tissue consists of two types of cells: the nerve cells and supporting glial cells (or simply glia). Glia have different types and outnumber nerve cells. In the CNS, astrocytes provide structural support for neurons, regulate the extracellular concentrations of neurotransmitters and ions, and facilitate information transfer at synapses. Radial glia is critical in the development of the nervous system. Both astrocytes and radial glia can ...

Condoms are a method of contraception used by both males and females. It acts as a barrier. A male condom constitutes a thin sheath that is usually made of latex (Alexander, 2016). On the other hand, the female condom is made of polyurethane sheath that has a flexible ring at the two ends (Edlin & Golanty, 2016). Condoms are intended for protecting people from contracting STIs during sexual intercourse. Besides, they are used as contraceptives. Condoms are grouped as class II medical devices since they exhibit the second lowest level of risk.
Various clinical studies have been conducted on various ...

This is a website of Multiple Sclerosis Association of America. Multiple sclerosis is an autoimmune disease wherein the myelin sheath sof the nerves are damaged causing symptoms such as numbness, fatigue, mobility problems and more (Mymsaa.org).
5 Facts

A steroid (Cortisone) was first to treat Multiple Sclerosis relapses in the year 1951.

The French neurologist, Jean-Martin Charcot gave MS its name in 1868.
The myelin sheath or the protective covering of nerves is damaged in MS.
“Lesions” or “plaques” are the inflamed or damaged areas in the brain and spinal cord.
Worldwide, about 2.5 million individuals have Multiple Sclerosis. (Mymsaa.org)

Nervous System

1. Neurons communicate with other neurons and stimulate both glands and muscles.
2. Match the following parts of the neuron and their function:

Dendrites input area, receives signals from other neuron conductive region; generates an action potential Soma (cell body) input area; main nutritional and metabolic area input area; receives signals from other neurons
Axon conductive region; generates an action potential
input area; main nutritional and metabolic area
3. Signals from other neurons are received at junctions called synapses, located primarily on the dendrites and cell bodies, the receptive and integrative regions of the neuron.
