Maurinko [17]

Answer:

The embryonic stage.

Explanation:

The prenatal development goes through three different stages:

  1. The germinal stage: Begins at conception and it takes place during the next 2 weeks.
  2. The embryonic stage: It takes place from week two to eight weeks after conception. During this stage, the embryo begins to differentiate itself into three layers that will become different systems of the body. By week eight, the basic structures of the brain and central nervous system have been established and the organs start to appear.
  3. The fetus stage: It takes place from week 9 until birth. The systems formed in the previous stage continue to form until they are ready for birth.

Therefore, the period of prenatal development that occurs two to eight weeks after conception. During this period, the rate of cell differentiation intensifies, support systems for the cells form, and organs appear is called the embryonic stage.

photoshop1234 [79]

Answer:

The answer is D. Another teacher puts his notes on PowerPoint and lectures from them to help students take precise notes that capture the content without misunderstandings.

Explanation:

Of all of the strategies the teachers used, this one is the least likely to meet the principal's expectations because it is the one that corresponds the least to the constructivist perspective in education. This perspective states that students should have a more active role in the learning process, and they should be able to apply knowledge to everyday situations outside school. They should also play an active role in the assessment of what they have learned, learning to reflect upon their learning process.

By putting his notes on PowerPoint so students can copy it, the teacher is not planning activities that involve student participation, on the contrary, they have a pasive role.
