In what phases is the genetic material in the cell correctly referred to as chromatids?
a. interphase and prophase
b. metaphase and telophase
c. anaphase and metaphase
d. metaphase and prophase e. interphase and telophase

Mitosis consists of four phases - prophase, metaphase, anaphase, telophase and cytokinesis.1. Prophase: Chromatin in the nucleus condenses and chromosomes pair up. Mitosis consists of four phases - prophase, metaphase, anaphase, telophase and cytokinesis

1. Prophase: Chromatin in the nucleus condenses and chromosomes pair up

2. Metaphase: Chromosomes line up at the center of the cell. The sister chromatids are joined together.

3. Anaphase: The sister chromatids separate from each other to the opposite sides of the cells.

4. Telophase and Cytokinesis: Membrane forms around each set of chromosomes on two opposite sides of the cells and cell divides into two identical daughter cells.

Therefore, chromatids are present in metaphase and anaphase. In prophase structures are called chromonema.

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c

yes it is weird but true
