Explain why lightning strikes can be dangerous even when an individual is not directly struck.
Ber [7]

Answer:

Lightning can be best described as an electrical discharge, which is caused by the imbalances between the clouds and the storm and the ground or sometime within the cloud. It carries around 20,000 to 30,000 ampere of current when it comes to the ground.

It is not only the direct hit of the lightning that make you worry, but any strike that is close to us can be dangerous to us as it results in the release of huge amount of electricity in the surrounding area.

stich3 [128]

Answer:

One method used by newborn mammals to generate heat is referred to as nonshivering thermogenesis. This method utilizes a protein channel called <u>thermogenin</u> which is present in high levels inside the mitochondria of <u>brown adipose tissue.</u>

Explanation:

Thermogenin forms a proton channel in the inner mitochondrial membrane in the brown adipose tissues. Most of the newborn mammals have these brown adipose tissues. In these tissues, the oxidation of nutrients do not produce ATP but generate heat. The heat is used by the newborn to maintain the warmer body temperature. The process is called nonshivering thermogenesis.
