He used Pea plants to help him find the laws of inheritance. He crossed homozygous (AA) tall plants with short (aa) plants and found that all of the off spring were tall, due to the fact that tall is dominant and short is recessive. He then conducted another experiment where all the offspring mated (all offspring were heterozygous (Aa)) And produced the F1 generation and 25 percent of the plants were short (use a punnet square to see why) and 75 percent were tall.
I hope this response helped :) If u have anymore q about mendelian genetics pls lmk !

Answer:
The correct answer will be- true and structural specializations
Explanation:
The evolution of life on earth has suggested that life has moved from the simplicity to complexity or from single-celled organism to multicellular organism.
This multi-cellularity is achieved through the property of called cellular differentiation and specialization. as the cellular complexity increases, therefore, cellular demands like the use of energy, food, water and other variables increased.
This lead to the formation of the organ and organs system specializes to perform specific functions like the digestive system and another biological system.
Thus, true and structural specializations are the correct answer.
Both move molecules from higher concentration to lower concentration.
Answer:
Some substances are made of only one kind of atom. Other substances are made of more than one kind of atom. How are the properties of these two types of substances different?
The properties of both atom differs as a result of presence of different constituents in their atom, the electron of an element made up of one atom would be different from another made up of two atom.
