Which of the following statements is true?

A Tt plant and a TT plant have the same genotype.
A TT plant and a Tt plant are both tall.
A Tt plant and a tt plant have the same phenotype.
A tt plant is called a hybrid because it has two recessive genes.

A TT plant and a Tt plant are both tall.

Explanation: T represents the allele for tall height and t represents the allele for short height. T is written in upper case therefore T is dominant while t is written in lower case therefore t is recessive. A dominant allele will be able to express itself phenotypically, that is, it will be able to show its observable trait in an organism even in the presence of a recessive allele. Since T is dominant, TT and Tt will both manifest as tall because T will be able to mask the outward effect of t.

answer: land bridge theory. land bridge theory held that shifting portions of dry land explained the finding of identical species on different continents. plate tectonic theory eventually eliminated the land bridge theory.

the cells uses some of the atoms of the glucose molecules to atp molecules. the atoms of the glucose molecules will then be converted into energy which will be eventually stored in atp. the energy produced which are stored in atp are coming from the glucose’s chemical bonds.
