1. If a Tt plant is crossed with a Tt plant, what is the chance that a tt offspring
will be produced?
75%
b. 25%
C. 50%
d. 100%

The Right Answer is 25%

B

Explanation:

T is the allele for tall plant, which is dominant trait. 't' is the allele for dwarf plant, which is a recessive trait.

Genotypes of the parent plants are- Tt and Tt. When they are crossed, there are 25% chances of producing tt offsprings. Refer the punnett square for this.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
