Bubonic Plague Lymph Nodes
503 words
Plague is a term applied randomly in the Middle
Ages to all fatal epidemic diseases, but now
restricted to an acute, infectious, contagious
disease of rodents and humans, caused by a short,
thick bacillus, Yersinia pestis. In humans, plague
occurs in three forms: bubonic plague, pneumonic
plague, and septicemic plague. Bubonic plague is
the best-known form and is so called because it is
characterized by the appearance of buboes, or
enlarged, inflamed lymph nodes, in the groin or
armpit or on the...

Zinc hyper accumulation in Thlaspi caerulescens as
a chemical defence against herbivore ABSTRACT
Thlaspi caerulescens is one of several plant
species known to accumulate heavy metals in excess
of 2 % of their above ground plant biomass. The
reasons for hyper accumulation are unknown, but
several studies conclude that it may be a plant
chemical defence. This has been of interest to
biologists because these metals are usually toxic.
The accumulation of these metals may serve as a
model for coevolu...

Silent Valley was actually the name adopted by the
British when they first saw the peculiar nature
related to this beautiful valley surrounded by
mountain ranges. The thing they noticed was the
silence in the forests in the valley. Unlike what
is found in the other forests of Kerala where
crickets hum throughout the day and become more
active as the night approaches, it was noticed
that here there was no humming even during the
night. The silence becomes eerily loud as we

Food Processing And Preservation

... methods, such as smoking or salting, which
yielded a palatable product, were generally
preferred. Commercial dehydration of vegetables
was initiated in the United States during the
American Civil War but, as a result of the poor
quality of the product, the industry declined
sharply after the war. This cycle was repeated
with subsequent wars, but after World War II the
dehydration industry thrived. This industry is
confined largely to the production of a few dried
foods, however, such as milk...

Sulfur Dioxide And Nitrogen Burning Of Fossil Fuels

What is Acid Rain? Acid rain is a form of
precipitation that falls to the earth as rain. For
rain to be acidic it has a pH level of less than
5. 6. The corrosive nature of acid rain causes
widespread damage to the environment. The problem
begins with the production of sulfur dioxide and
nitrogen oxides from the burning of fossil fuels,
such as coal, natural gas, oil and other kinds of
manufacturing. When these pollutants are in the
air, they react with water and other chemicals, to
form sulfuric...

hundreds of years of genetic modification by
farmers and scientist in search of desirable

Ice Storm Carbon Dioxide

INTRODUCTION Ice storms, also referred to as glaze
storms, cause considerable damage every year to
trees in urban and natural areas. They vary
considerably in their severity and frequency. Ice
storms are result of the ice formation process,
which is influenced by general weather patterns.
Ice accumulates when super cooled rain freezes on
contact with surfaces, such as tree branches, that
are at or below the freezing point (0 C). This
generally occurs when a winter warm front passes
through an ar...

Plants Food Seeds
388 words
Plants give us lots of things including oxygen,
foods, and medicines. Plants need things like
water, light, and air. The amount of daylight
affects their growth. Plants also need food, just
like we do. The different parts of a plant help it
make food. Some plants cross-pollinate. These
plants have male (the stamen), or female (the
carpel) parts. Wind and water sometimes scatter
the pollen, but insects do most of the work. Other
plants pollinate themselves. A new plant is born
from a seed. The se...

Human Biology and Evolution Humans are Alive The
earliest human life form can be traced back more
than 3. 5 billion years ago. Humans are said to be
descendants of a single celled ancestor. Although
they are different in size and shape all basic
functions are alike. The more complex the
organization of the cell became the more
successful and developed it became. As these
single celled organisms developed they became
known as pre-humans. We share many characteristics
with these pre-humans. Some o...

taking the bubble with them underwater. Most
