The Human Egg Cell. The human egg cell is also known as the ovum. With a spherical structure it is the largest cell in the human body measuring about 0.2mm in diameter. The function of the ovum is to reproduce‚ when fertilized by the sperm cell the ovum is capable of creating a new living organism. The size and shape of the ovum gives it space to store and create nutrients (see fig 3) (Boyle and Senior 2008) The ovum is bounded by the egg follicles of the ovaries and is produced by primitive germ

The effect of environmental factors such as temperature‚ osmotic pressure‚ oxygen concentration and pH on microbial growth and survival Abstract: Microbial growth can be affected by different environmental factors such as temperature‚ osmotic pressure‚ oxygen concentration and pH. Six experiments were carried out in this report testing for microbial growth against different environmental factors. Good aseptic techniques were used to prevent contamination‚ resulting in a uniform set of results

can be modified? Detection of changes in blood pressure (leading to resultant changes in blood vessel diameter): Baroreceptors at the carotid sinus (the bifurcation of internal and external carotid arteries in the neck) and the aortic arch detect changes in blood pressure. These non-encapsulated nerve endings‚ located in the adventitial layer of arteries‚ are technically mechanoreceptors; they respond to arterial distension occurring due to a change in blood pressure. Afferents from the carotid region
