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.

The lineage of pea plants produced round seeds for four generations. The plants that fertilized these pea plants also produced r

adell [148]

Yes, it is possible.

In this case both of the parental plants were heterozygotes and they manifested dominant allele in their phenotype, which is round seed.

P: Aa x Aa

F5: AA, Aa, aA, aa - possible genotypes in fifth generations.

A- dominant allele (round seeds); a- recessive allele (wrinkled seeds)

Wrinkled phenotype is manifested only if there are two recessive alleles present.
