The correct statement is that "Archaea are older organisms than eukaryotes"

  • Archaeans are group of organisms classified under the domain Archaebacteria. They are found in environments with extreme conditions e.g. high temperature etc.

  • They are prokaryotic in nature i.e. they do not possess a membrane-bound nucleus in their cells.

  • Based on this, archaea are not classified under the same domain as bacteria (domain- protista). They are unicellular organisms.

  • However, archaea are older set of organisms than eukaryotes. This is the correct statement among the options provided.

A male flying tree squirrel with a medium-length tail has babies with a female with a medium-length tail. Over the years their t
o-na [289]

Answer:

Explanation:

(a) The mode of inheritance for the tail length would be incomplete dominance. In this type of inheritance, one of the alleles representing a gene in heterozygous conditions exert incomplete dominance on the other allele giving rise to a new phenotype.

(b) The likely genotype of the parents are heterozygous. The medium tail length results from the incomplete dominance of the long tail allele on the short tail allele. There is no allele for the medium tail length itself.

(c) Assuming that the allele for long tail length is T and that of short tail length is t, the genotype of the parents would Tt. Crossing the two parents

      Tt     x     Tt

  TT    Tt    Tt    tt

TT - Long tail = 1/4

Tt - medium tail = 1/2

tt - short tail = 1/4

(d) From the expected phenotype ratio

Expected number of offspring with long tail = 1/4 x 52 = 13

Expected number of offspring with medium tail = 1/2 x 52 = 26

Expected number of offspring with short tail = 1/4 x 52 = 13

True or false? the chemiosmotic hypothesis states that the synthesis of atp generates a proton gradient that leads to electron f
lapo4ka [179]

Answer:

False

Explanation:

The chemiosmotic hypothesis states that the flow of electrons through an electron transport chain generates a proton gradient that leads to the synthesis of ATP. A proton gradient across chloroplast and mitochondrial membranes drives ATP synthesis by the enzyme ATP synthase.
