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.

On your first research mission you make an amazing discovery by finding a new species living in the hostile environment of the s

Tomtit [17]

The best classification for this new species is Animalia.

According to the six kingdom classification given by Carl Woese, all organisms are divided into 6 kingdoms.

1) Archaebacteria

2) Eubacteria

3) Protista

4) Fungi

5) Plantae

6) Animalia

As the newly discovered species is a multicellular (made up of more than one cell) organism.

Then it can only belong to Kingdom Fungi, Plantae and Animalia as the rest of the kingdoms like Archaebacteria, Eubacteria and Protista consist of unicellular organisms that are made up of only one type of cell.

Now this species is not autotrophic ( i.e. an organism that can get its own nutrition by the use of light, water, carbon dioxide, or other substances).

It means it is heterotrophic which means it can't get nutrition on its own.

Out of the Fungi, Plantae and Animalia , only fungi and Animalia kingdoms consist of heterotrophic organisms.

Now this species also does not contain chitin which is an important characteristics of Fungi.

So only option left is Animalia.

Hence, the best classification for this new species is Animalia.
