The condition which is most likely to cause death of a botulism patient is Respiratory failure.
Explanation:
The causal organism of Botulism is the bacteria <em>Clostridium botulinum.</em>
It is usually found in canned food and causes a very severe food poisoning.
The bacteria release botulinum toxin on reaching the intestine of the person and from their the toxins are absorbed into the blood.
Botulism mainly effects the neuromuscular system of the body. .
The basic symptoms of botulism is characterised by weaknes in limbs , jaws and eyes.
A decreased muscular activity sometimes causes constipation due to slowed down peristalsis.
Sometimes nausea , vomiting and diarrhea may occur.
If left untreated and in severe cases, the toxins may proceed to effect the respiratory muscle thus hindering the proper breathing and gaseous exchange.
A further damage could result in the respiratory failure.
I think it's D. It shields life forms on the surface from radiation?
The correct answer is option C
The demand for a better life increased the pollution in the society. The increased pollution in the environment led to many health problems.
The Nuclear power plant creates radioactivity and thermal pollution.
The water used in the nuclear power plants is very warm and causes thermal pollution as it is released into water bodies.
The nuclear power plant uses radioactive substances like uranium and the waste that is left is radioactive waste.
Answer: B
Explanation:
carbon monoxide is poison and can kill you
Nitrogen is the major nutrient required by grass and is used to
stimulate high growth rates and is key to achieving high yields, however
if too much nitrogen is applied this can have a negative effects on
quality.
High rates of nitrogen can also cause problems with silage
fermentation due to excess nitrate having a negative impact on the
fermentation process and will produce silage that is less palatable and
the animals will be less keen to eat it.

Nitrate is generally taken up by grasses quicker than it is
incorporated into proteins and until used this excess known as luxury
uptake is stored in the leaves. Excess nitrate will be present if
insufficient time is allowed between application and mowing and can also
occur under conditions of poor growth eg low light levels, cool
temperatures. It is also a problem if there is a dry spell after
application, when nitrate cannot be taken up by the roots, followed by a
period of wet weather that results in luxury uptake. The plant cannot
convert it to protein quickly enough so it accumulates in the plant.

High rates of nitrogen may cause a reduction in crop sugars as they
are used to provide energy for the increased rate of plant growth and
for the manufacture of plant proteins and this increased growth rate may
in turn lead to lower crop dry matter content although in practice this
is often not significant.
Excess nitrate can be avoided by following the Grassland Rule to apply nitrogen at the rate of no more than 2.5 kg N/ha/day.
