Why do individual water masses within the oceans retain distinctive physical properties for long periods?
LekaFEV [45]

Answer:Water masses give a very robust representation of the thermohaline state of the ocean and ocean circulation. ... This water body shows extremely stable vertical stratification, and its water density changes from ~1,011 kg/m3 at the ocean surface to ~1,016 kg/m3 at 100‐m depth.

The stages of mitosis were originally defined by cellular features observable through a light microscope.
Brrunno [24]

Answer: TRUE

Explanation:

The cell division that takes place during the growth and development of an organism is in an as MITOSIS. Mitosis takes place in somatic cells that is, body cells that are not involved in the production of gametes. The difference stages of mitosis were originally defined by cellular features observable through a LIGHT MICROSCOPE. These stages includes:

--> PROPHASE: when viewed under a light microscope, each chromosome shortens and thickens and is seen to consist of two chromatids. The Centriole begin to separate.

--> METAPHASE: The nuclear membrane disappears, a spindle forms, the chromosomes line up across the middle of the cell and become attached to the spindle fibres at their centromeres.

--> ANAPHASE: The sister chromatids are pulled apart to opposite ends of cell as the spindle fibres contract.

--> TELOPHASE: A nuclear membrane forms around each set of chromatids, and the cell divides into two daughter cells.

This procedure for measuring cell size has certain limitations . List three such limitations​
marusya05 [52]

The limitations of cell size are:

1) Surface area to volume ratio

2) Nucleo cytoplasmic ratio

3) Fragility of cell membrane

What are the cause of limitations on cell size?

The need for a surface area of sufficient area to allow the cells function→.

→If the surface area of cell increase volume increase to the cube of the linear increase.

→ Nuclie contains information needed for protein synthesis . Some cells reduce this limitation to increase the no. Of nucleus called multinucleated.

Examples are muscle cells.
