ONLY ANSWER IF YOURE AN EXPERIENCED FISH KEEPER<br> is my female swordtail pregnant?
LenKa [72]

Answer:

I don't know what your fish looks like but I will try my best :)

To accommodate the developing eggs, the mother's body expands, becoming deeper and broader. A few days before delivery, she develops a bulge below the gills, her outline becoming fairly square in this region, while the gravid spot has enlarged its area. The female swordtail and guppy will both give birth to anywhere from 20 to 100 live young after a gestation period of four to six weeks, and mollies will produce a brood of 20 to 60 live young after a gestation of six to 10 weeks.

Observe the two plants. Which cellular change affected the structure of second plant?
OLEGan [10]

Answer:

The correct answer is option D which is release of water from the vacuoles.

Explanation:

The difference in second plant from the first one is rigidity. Second one is wilted and not rigid. This is due to the release of water from the vacuoles in the cell of plants.

Vacuoles are present in the center of plant cell. They are usually filled with water and provide structural support to the cell.

In the absence of water filled vacuoles, plants shoots are wilted as in case of second plant.

Answer:

A temporary lake create salt flats in Death Valley when Holocene lakes began to evaporate.
