Answer:
Lysosome (more info below)
Explanation:
the Lysosome’s main job is to transport undigested material to the cell membrane for excretion from the cell. They digest excess or worn out organelles, food particles, and engulfed viruses or bacteria. Lysosomes are like the stomach of the cell.

Answer:
Decreased transcription of structural genes of try operon irrespective of presence or absence of tryptophan. The leader sequence has a tryptophan codon in its sequence 1 that does not allow the formation of attenuator structure when tryptophan levels are low.
Explanation:
The leader peptide has a tryptophan codon in sequence 1. When tryptophan levels are low, translation of sequence 1 pauses at the tryptophan codon and the sequences 2 and 3 pair with each other. This does not allow pairing of sequences 3 and 4 and the formation of the attenuator is inhibited. Therefore, tryptophan operon is expressed when tryptophan levels are low.
When the leader peptide sequence is replaced with the one from phenylalanine operon, expression of tryptophan operon will be reduced. The replaced sequence lacks a tryptophan codon and therefore, the translation would not pause when the tryptophan levels are low. This would allow the ribosome to quickly translate the sequence 2. Sequences 3 and 4 will pair to form attenuator and the gene expression will be reduced irrespective of low levels of tryptophan.

Answer:
1. SnapDragon - incomplete dominance
2. Cows/chickens- multiple alleles
3. Blood type in humans - co-dominance
4. Skin and hair color - polygenic inheritance
Explanation:
1. Sometimes, the phenotypic expression of a recessive allele cannot be completely covered by that of the dominant allele. This is called incomplete dominance. Flowers of snapdragon and four'o clock plants are the example of such an event where the recessive allele for flower color, which is white is also expressed in heterozygous plants along with the dominant red color, producing pink flowers.
2. Multiple alleles determine the genetic traits of cows and chickens.
3. There are three alleles in humans that determine the blood type - dominant Ia and Ib for A and B type respectively, and recessive Io for O type. when in a heterozygous person, both dominant alleles are present, both are expressed phenotypically forming AB type blood. this is called Co-dominance.
4. Skin and hair color in humans is determined by multiple alleles present in different chromosomes. this is called polygenic inheritance.
