The Trachea

laila [671]

Answer:

There will be less animal life in lake Raymond in the next year.

Explanation:

In the year with heavy rain, this has caused the depth of Raymond lake to be increased. This will bring an increase in the growth and survival of more water plants and animal species.

In the second year where there is a decrease in the water level, the animals and water plants will face problems. The worst hit are those plants and animals species that lives at a much deeper path of the lake with the least sunlight or any external factors that are now going to be more exposed due to low water level..

Thiamine (vitamin B1) deficiency diseases have a lower prevalence now than in the past. However, they are seen as beriberi in so
Misha Larkins [42]

Answer and Explanation:

      Vitamin B (thiamine) is usually found in cereals, grains, vegetables and meat among other foods. Ingestion of this nutrient through balanced diet is one of the most important measures for the control of Beriberi. Not only the consumption of thiamine sources, but also the decrease in beverages that may disturb the absorption of thiamine, such as coffee and alcoholic beverages.

     Beriberi is a serious disease directly linked to the lack of thiamine, also known as Vitamin B1. This disease can lead to death, but with proper treatment, it is possible to achieve cure. When vitamin B1 is not consumed regularly in food, mild symptoms of beriberi may arise such as insomnia, nervousness, irritation, fatigue, loss of appetite and energy. These problems may manifest themselves after two to three months of exclusively consuming thiamine-poor foods. Symptoms can still develop into more severe symptoms such as numbness, tingling and swelling of the legs and arms, difficulty breathing, heart problems, heart failure and even death.

   Wernicke-Korsakoff syndrome), also known as alcoholic encephalopathy, cerebral beriberi, among others, is a neuropathy related to vitamin B1 deficiency, and indirectly (but more commonly) acute alcoholism, because alcohol interfere in body's ability to absorb thiamine.

  Vitamin B1 is related to the process of transformation of pyruvic acid, which is responsible for performing biochemical transformations of proteins, fats and mainly carbohydrates. When this element is lacking in the body, neurons are the most affected cells, causing these sympthons above.
