SF6 AND XeF4 are the species that will have an expanded octet structure.

Sulfur hexafluoride (SF6) has an octet geometry where one sulfur atom is surrounded by 6 fluoride atoms. Xenon Tetrafluoride (XeF4) is a square planar compound and an octahedral because of the presence of lone pairs of electrons.

Galactosemia is a metabolic disorder characterized by the inability to metabolize the sugar galactose. People with galactosemia
Umnica [9.8K]

Answer:

Genetic mapping for unequivocal identification of the potentially causative mutation  

Explanation:

Galactosemia is a genetic disorder caused by mutations in the Galactose-1-phosphate uridylyltransferase (GALT) gene, which encodes an enzyme involved in the metabolism of galactose. Gene mapping is a technique widely used in genetics to identify the position of one locus a chromosome by using molecular markers to estimate genetic distances. Genetic mapping provides useful evidence in order to identify when a disease that is transmitted from parent to offspring can be associated with one or more genes and then determine which gene/s is/are responsible for this condition.

In pea plants, the allele for tall stalks (T) is dominant over the allele for short stalks (t). Suppose a cross between a tall p
vazorg [7]

Answer:

Tt - 1/2

tt - 1/2

Explanation:

<em>A cross between a tall pea plant and a short pea plant that produces 43 tall and 47 short offpsring (almost 1:1) is most likely a cross involving a heterozygous tall individual and a homozygous short individual.</em>

Tt   x   tt

Offspring = Tt   Tt   tt   tt (50% tall and 50% short)

If one of the tall offspring (Tt) is crossed with one of the short offspring (tt):

Tt   x   tt

Offspring = Tt   Tt   tt   tt

Genotype ratio = 2Tt:2tt

Hence,

Tt = 1/2

tt = 1/2

Anarel [89]
The correct answer to this question is letter " a. metaphor." <span>Your words are bees about a pear-tree. From that statement, it is comparing words to the bees without the use of any keywords like "like and as ... as." So this is definitely a metaphor, not a simile.</span>
