A. Dna thats pased down from parents to offspring
The essential information the product of the bicoid gene in Drosophila provides during development is (D) orientation of the anterior-posterior axis.
Bicoid is the maternal gene that acts as a morphogen. It expresses itself on the basis of its concentration gradient. The concentration of bicoid is high towards the anterior region, hence the region where bicoid protein is expressed les is the posterior portion.
Drosophila is the fruit fly commonly found in the households. It is one of the most studied model organism in developmental biology. This is because it can reproduce rapidly, has a relatively simple structure and is cost-effective.

The metazoa the group whose members lack cell walls are multi cellular and heterotrophic
The correct answer is: Enzymes
When tissues and cells are damaged great quantities of certain enzymes are released into the bloodstream. Enzymes can be elevated in response to cardiac or other organ damage. So, for example creatine kinase is an enzyme found mostly in heart muscle and its concentration increases when there is damage to the heart muscle cells
The answer is definitely B
