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.
In both animals and plants, cells produce new cells by mitosis - but they split differently. A cleavage farrow forms in the animal cell and it splits. For the plant cell, a cell plate forms and then the cell splits.
Answer:
The correct answer will be option-Carpel
Explanation:
The carpel is the basic unit of the female reproductive organs or gynoecium which is present in the flower either in the fused form or free form.
The carpel is the innermost part of the cell which comprises of three structure: style, stigma and ovary. The carpel is surrounded by the male reproductive organ.
The carpel is formed from the floral meristem (diploid structure) through mitotic division therefore carpel is diploid in nature.
Thus, option-Carpel is the correct answer.
Yeah i can’t see the 2 scenarios too
Answer :a. the polygenic nature of sickle-cell disease
Explanation:
<u>SS is a genetic disorder in which more than two genes control a single character</u>. Contrary to single gene to a trait. It exhibit an abnormal clinical heterogeneous traits for Mendel inheritance with multiple factors exerting influence on an individual disease outcome. Therefore multiple complications arises with symptoms
