Answer:

a Anaphase I

b Metaphase I

c Telophase I

d Anaphase II

e Prophase I

f Telophase II

Explanation:

Prophase I begins after the DNA has been duplicated, as shown in picture e. The chromosomes are condensed, and also visible, which is apparent in picture e.

The next stage is called Metaphase I, in which the pairs of homologous chromosomes align at The the centre of the cell and the spindle fibres attach, as shown in picture b.

The pairs of chromosomes are pulled apart to opposite poles of the cell by the spindle fibres., as shown in picture a. This stage is called Anaphase I.

Then, a process called Telophase I occurs, when the cell divides into two daughter cells. One of these cells is shown in picture c.

Picture d shows the stage Anaphase II, where the spindle has attached and the chromatids are pulled to the opposite poles of the cell.

The final picture left is picture f, which shows the daughter cell at the end of meiosis II, where the nuclear envelope is reforming, as in telophase II.

What is a cephalopod?
klio [65]

A cephalopod is a predatory-like mollusk of the large molluscan class of Cephalopodan animals. This includes cuttlefish, octopus, squid, and/or nautilus. They are animals that live in the ocean. Additionally they eat foods like fish and jellyfish on regular and customary occasions. They sometimes possess cannibalism by eating their own species, which is absolutely crazy. Anyways, I hope that this has helped you today.. :)

During the late cretaceous, the bisti badlands were home to numerous animals including turtles, crocodiles, and even dinosaurs.
vaieri [72.5K]
These animals were living in an environment with a warm climate that results in changing sea levels. These conditions create a lot of shallow inland seas allowing these animals to thrive. The Cretaceous period is the last period of the Mesozoic area where new groups of mammals, birds, and flowering plants appeared on Earth.
