Give one example of a parasitic fungi and explain how it affects human health.
Zarrin [17]

Answer: Many pathogenic fungi are parasitic in humans and are known to cause diseases of humans and other animals. In humans, parasitic fungi most commonly enter the body through a wound in the epidermis (skin). Such wounds may be insect punctures or accidentally inflicted scratches, cuts, or bruises. One example of a fungus that causes disease in humans is Claviceps purpurea, the cause of ergotism (also known as St. Anthony’s fire), a disease that was prevalent in northern Europe in the Middle Ages, particularly in regions of high rye-bread consumption. The wind carries the fungal spores of ergot to the flowers of the rye, where the spores germinate, infect and destroy the ovaries of the plant, and replace them with masses of microscopic threads cemented together into a hard fungal structure shaped like a rye kernel but considerably larger and darker. This structure, called an ergot, contains a number of poisonous organic compounds called alkaloids. A mature head of rye may carry several ergots in addition to noninfected kernels. When the grain is harvested, much of the ergot falls to the ground, but some remains on the plants and is mixed with the grain. Although modern grain-cleaning and milling methods have practically eliminated the disease, the contaminated flour may end up in bread and other food products if the ergot is not removed before milling. In addition, the ergot that falls to the ground may be consumed by cattle turned out to graze in rye fields after harvest. Cattle that consume enough ergot may suffer abortion of fetuses or death. In the spring, when the rye is in bloom, the ergot remaining on the ground produces tiny, black, mushroom-shaped bodies that expel large numbers of spores, thus starting a new series of infections.

When your cell makes a new compound, such as glycogen from many glucose molecules, usable energy is needed and is obtained by wh
Licemer1 [7]

When cells makes a new compound, such as glycogen from many glucose molecules, usable energy is needed and is obtained by removing a phosphate group from ATP, producing energy plus ADP plus phosphate.

<h3>What is ATP?</h3>

This is referred to as adenosine triphosphate and is the energy currency of the cells.

This is  usually formed from the synthesis of ADP and a phosphate group thereby making it the most appropriate choice.

What is the acceleration due to gravity on another planet if the potential energy of an object on
Andreyy89

Answer:

g = 66.7 ms^-2 (3 s.f.)

Explanation:

Potential Energy -> PE

m -> mass

g -> acceleration due to gravity

h -> height

using the formula, PE = mgh

600 = 3 × g × 3

9g = 600

g = 600/9

g = 66.666

g = 66.7 ms^-2 (3 significant figures)
