Aheterozygous male and a homozygous female plants are cross-pollinated. what is the genotypic ratio of the offspring

When a heterozygous male and homozygous female plants are cross-pollinated the genotypic ratio of the offspring will be tt, Tt

Explanation:

In a pea plant, when the heterozygous male plant (Tt) is cross-pollinated with homozygous female plant (tt) ;

T × t = Tt

t × t = tt

t × T = tT

t × t = tt

Therefore, the genotypic ratio of the offspring is short and tall (tt, Tt) because the dominance of tall trait is less that the short trait, indeed the chances of tall offspring is low.

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.

it's diluted or concentrated

in a diluted solution, you can add a lot more solute but in concentrated only a little more can be added
