The majority of signal molecules are peptides and small proteins. Both are made of a chain of amino acids, the difference being the number of amino acids that make up the molecule. Generally, if the signal molecules has fewer than 50 amino acids it is considered a peptide. If it has more it is considered a protein.

The proportion of F2 offsprings expected to be tall and yellow is 3 out of 16.
Mendel's Second Law is used in this case.
1. The genotype for the true-breeding tall, green podded plant is TTGG. The genotype of its gamete is TG.
2. The genotype for true-breeding short, yellow podded plant is ttgg. so, its gamete is tg.
3. When both gamete are crossed, it will produce F1 generation with genotype of TtGg.4 All F1 generation is 100% or heterozygous tall, green podded plant.
4. Now we would like to cross the F1 generation among themselves. So, there 4 possibilities of gametes produced by a single F1 generation plant which are TG, Tg, tG and tg.
5. Using a Punnett Square, these gametes from 2 F1 generations will be crossed, resultiing in 16 different type of genotypes of F2 generation. (shown in picture)
Answer:
Cells are small in order to get pass barriers. In particular, it has a small surface area to volume racio, which in turn allows it to carry more materials.
Explanation:
If cells are way to massive, it will require much more more energy to move the cell, the cell would not be able to remove all of its waste, and it would not get enough nutrients to survive
Answer:
because it has a four chambered heart
