Is there a question or are you asking
Answer:
ZZ species will take more number of crosses to produce a recessive offspring.
Explanation:
Here Z seems to be the dominant allele. A species having ZZ or homozygous dominant genotype shall not express the recessive phenotype until unless it has both recessive allele and this is not possible as of now or is dependent on the genotype of mating species and the number of generations of development.
If ZZ mates with WW, the offspring in F1 generation will have genotype ZW
However, if the offspring in the F1 generation are crossed then in next generation we could see organism with recessive phenotype i,e WW
ZW*ZW
ZZ, ZW, ZW, WW
While in case of organism having ZW type genotype, recessive phenotype will occur in the first generation cross with the ZW.

Hope this helps :)
I say C. <span>it lowers the activation energy of a reaction in affects only very specific reactions. Correct me if I'm wrong tho...thank you ;)</span>
The statement is true that T-cells are a type of immune cell system that recognizes pathogens in the body.
T-cells are the lymphocytes that are involved in providing acquired immunity to the body. They can recognize the pathogens presented by the antigen presenting cells. There are two types of t cells: helper T cells and Cytotoxic T cells.
Immune cells are the cells of the immune system that are involved in protecting the body from infection, allergies and foreign pathogens. There are several immune cells that perform several functions. The example of such cells are: phagocytes, lymphocytes, dendritic cells, etc.
