Answer:

The correct answer is C. Only one cell layer is found in a blastula.

Explanation:

A blastula is a multicellular embryo having a single-layer structure, a stage in the development of the embryo that the eggs of most animals pass through, as the final result of the process of egg crushing. This follows the morula stage and completes the cleavage. In the narrower sense, blastula is only the “bladder germ” that occurs in many animals and encloses a liquid-filled cavity, the so-called blastocoel.

Allison is playing in a high school field hockey game and passes the ball to Erika, who appears to have a scoring opportunity. A
Readme [11.4K]

Answer:

True.

Explanation:

The developmental theory of George Herbert Mead of Role-Taking theory suggests that self-development takes place through the process of the role-taking that is divided into three stages. These stages are:

  1. The Preparatory Stage
  2. The Playing Stage
  3. The Game Stage

<u>In the given case, it is the </u><u>game stage of the Role-taking theory</u><u>. The </u><u>Game Stage</u><u> is the final stage in the theory. In this stage, a child, who is of seven years of age or above, begins to understand the rules of the game. The children begin to understand their roles as well as the role of other players in the game. So, the act of Allison's passing the ball to Erika, despite the opportunity of her scoring, is an example of </u><u>the game stage</u><u>.</u>

So, the answer is true.
