Can someone explain Meiosis 1 and II to me like I'm a baby? (i really don't understand it!) 15 pts
topjm [15]

Answer:

Meiosis 1 is when the homologous chromosomes separate and crossing over occurs. Meiosis 2 is when the sister chromatids seperate and produces 4 haploid daughter cells.

Explanation:

The phases of Meiosis 1 are, Interphase, Prophase 1, Metaphase 1, Anaphase 1, Telophase 1 & Cytokinesis.

Interphase: DNA is replicated and organic material is synthesized.

Prophase 1: Chromosomes pair up

Metaphase 1: Crossing Over occurs and chromosomes line up at the equator.

Anaphase 1: Chromosomes pull apart

Telophase 1 & Cytokinesis: Cell pinches to both sides and begins to pull apart as the cytoplasm is copied.

The phases of Meiosis 2 are, Prophase 2, Metaphase 2, Anaphase 2, Telophase 2 & Cytokinesis.

Prophase 2: Two daughter cells are formed

Metaphase 2: Chromosomes line up at equator of both cells.

Anaphase 2: Sister chromatids are pulled apart in each cell.

Telophase 2 & Cytokinesis: The cells pinch to both sides as the cytoplasm is replicated and four granddaughter cells are formed.

Case study - are invading bullfrogs harmful?
andrew-mc [135]
The invading bullfrogs ARE HARMFUL. This is because, they cause decline in the population of the native species.
Decline in the population of the native species will throw the ecosystem into a condition of imbalance which will eventually affect all the living organisms that are living in that ecosystem.
