The correct answer is: Endoderm

en·do·derm

the innermost layer of cells or tissue of an embryo in early development, or the parts derived from this, which include the lining of the gut and associated structures.

blas·tu·la

an animal embryo at the early stage of development when it is a hollow ball of cells.

mes·o·derm

the middle layer of an embryo in early development, between the endoderm and ectoderm.

ec·to·derm

the outermost layer of cells or tissue of an embryo in early development, or the parts derived from this, which include the epidermis and nerve tissue.

Answer:

The correct answer is - eliminates all lymphocytes that have been built that would bind and kill healthy, unaffected body cells.

Explanation:

Self-testing in the immune system is a very important step as it helps in analyzing if the immune cells or lymphocytes. To fight against the intruders, the immune system should initially recognize them. That is, the immune system must have the option to recognize what is nonself (remote) based on what is self. The immune system can make this identification since all cells have distinguishing recognition molecules (antigens) on their surface.

Self-test helps in identifying and eliminate in all lymphocytes that have built and attack the healthy cells and killing them.

Bear pigmentation is subject to epistasis of the B alleles by the d alleles. B (black) is dominant over b (brown). D is dominant
White raven [17]

Answer:

9/16 black, 3/16 brown, 4/16 white

Explanation:

             BD         Bd          bD         bd

BD     BBDD      BBDd     BbDD     BbDd

Bd      BBDd      BBdd     BbDd      Bbdd

bD      BbDD     BbDd      bbDD     bbDd

bd       BbDd    Bbdd       bbDd     bbdd

A punnet square can be described as a diagram which is made to predict the genotype as well as the phenotypes of the offsprings of a cross.

To study the epistatis nature of the pigmentation in bear, a punnet square was made and the results of the punnet square are shown above.

The results of the punnet square show that the cross between two bears will have the chances of producing 9/16 black bears, 3/16 brown bears and 4/16 white bears.
