A Correct answer
Explanation

Cadmium (Cd) is one of the most toxic elements to which humans could be exposed at work or in the environment. The outbreak of itai-itai disease, which is the most severe stage of chronic Cd poisoning, occurred in the Cd-polluted Jinzu River basin in Toyama.

Multiple choice chemistry chemistry in daily life food spoilage and food preservation methods of preserving food chemicals in food

A lot of controversy has been generated over the use of 'BVO' in soft drinks on the ground that it is carcinogenic (cancer-causing). What is 'BVO'?

  1. Brominated vegetable oil

  2. Basic vitamin overdose

  3. B-complex vitamin overdoes

  4. Bakery vanilla odour
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

BVO stands for brominated vegetable oil which is a food additive sometimes used to keep citrus flavoring from separating out in some sodas and sports drinks.

It is a complex mixture of plant derived triglycerides that have been reacted to contain atoms of the elements bromines bounded to the molecules.

Multiple choice evs - i methods of preserving food food spoilage and food preservation chemicals in food food chemistry

Some scientists believe that a chemical widely used as a preservative and a colouring agent in foods gets converted to an acid in the stomach, affects the genes and causes cancer in human beings. Identify that substance.

  1. Ferric chloride

  2. Sodium nitrite

  3. Vinegar

  4. Sulphur dioxide
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Sodium nitrite and nitrate closely are related chemicals that have been used for centuries to preserve meat. While nitrate itself is harmless, it easily converts to nitrite, which when combined with secondary-amine compounds forms nitrosamines, a powerful cancer-exacerbating chemical. This chemical reaction occurs easily during the frying process.

Multiple choice biology diseases and hygiene anaemia mosquito and human health non communicable diseases

Increased asthmatic  attacks in certain seasons are due to 

  1. Inhalation of seasonal pollen

  2. Heat and huminity

  3. Low temperature

  4. Eating preserved fruits
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Asthma is a common long-term inflammatory disease of the airways of the lungs. Symptoms include episodes of wheezing, coughing, chest tightness, and shortness of breath. Environmental factors which are responsible for asthma include exposure to air pollution and allergens. The increased asthmatic attacks in certain seasons are due to the inhalation of seasonal pollen. Seasonal pollen is obtained by the dehiscence of pollen grain in a particular season to which a person may be allergic.

So, the correct answer is 'Inhalation of seasonal pollen'.

Multiple choice biology diseases and hygiene anaemia mosquito and human health non communicable diseases

Increased asthmatic attacks in certain seasons are related to

  1. Inhalation of seasonal pollen

  2. Eating of seasonal vegetables

  3. Low temperature

  4. Wet and dry environment
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Pollen allergies are very common and in a season of pollination. If a person inhales or come in contact with that pollen in the garden or area with lots of plants will create a severe impact and increase the asthmatic attack and other problems like sneezing and able to block certain passages inside the body.

So the correct option is 'Inhalation of seasonal pollen'.
