The chromosomes in a pair each have a different Alleles for each gene. But same gene.
Answer:
Operons afford the organism the opportunity to simultaneously regulate transcription of multiple genes, whose products are active in the same process.
Explanation:
Operon is the group of related genes and the operator and promoter sequences that regulate their expression. All the genes in an operon are expressed together and are under the regulation of the same promoter and operator sequences.
Operons consist of the genes that are involved in related metabolic pathways. For example, the genes that code for the enzymes of lactose catabolism are expressed together as lac operon. It allows simultaneous expression of the genes of lactose catabolism only when lactose is present in the medium. Similarly, these genes are inhibited simultaneously in absence of lactose by binding of repressor protein to the operator sequence.
1. The water will leave the cell.
Hypertonic solution
2. There will be no net movement of water.
Isotonic solution
3. The water will leave the cell.
Hypertonic solution
4. The water will enter the cell.
Hypotonic solution
5. I predict that the water will move into the cell because inside the cell, the concentration of water molecules is less than that of outside the cell. According to the process of osmosis, water moves from a region of high water concentration to a region of low water concentration.
Thank you
Answer:
Option (D)
Explanation:
Dinosaurs are the extinct species that were very well structured and developed and were enormous. They existed on earth during the Mesozoic era, which includes the Triassic, Jurassic and Cretaceous period and the rocks of this age are found to comprise of their fossils at different places on earth. They were extinct about 65 million years back i.e. by the end of the Cretaceous.
They were Archosaurs, which belongs to the group of diapsid amniotes and are mainly classified as reptiles. They also had some property of endothermy, where an organism can maintain their body temperature by carrying out the processes related to metabolism. So, they were able to control their body temperature.
Thus, the correct answer is option (D)- all of these.
