ANTONII [103]

Answer:

The correct order is

5, 4 , 3, 2, 1

Explanation:

The first stage is the fusion of sperm  with egg in fallopian tube which induces chemical reactions that prevents fusion of multiple sperm with one egg. This is known as preventing polyspermy.

After this the fused egg starts dividing and growing through the process of mitosis. The growing zygote reaches the stage of morula after few cell division and continues the division process till it reaches the stage of blastocyst.

The blastocyst now move down the fallopian tube to attach to the wall of uterus. This stage is known as implantation.

Hence, the correct order is 5, 4 , 3, 2, 1

Here are the answers to the three questions on the right side of the page, as for the left, those are your own opinions, remember?

  • plate tectonics: a theory explaining the structure of the earth's crust and many associated phenomena as resulting from the interaction of rigid lithospheric plates which move slowly over the underlying mantle.
  • three different types of late boundaries:Divergent boundaries -- where new crust is generated as the plates pull away from each other. Convergent boundaries -- where crust is destroyed as one plate dives under another. Transform boundaries -- where crust is neither produced nor destroyed as the plates slide horizontally past each other.
  • crustal features formed at plate boundaries: Deep ocean trenches, volcanoes, island arcs, submarine mountain ranges, and fault lines are examples of features that can form along plate tectonic boundaries.

hope this helps ^^

7. When did whale ancestors begin living full time in the water?
antoniya [11.8K]
Around 40 million years ago

The earliest whales that we think were fully aquatic, that is, they never left the water, are found around 40 million years ago, during the middle Eocene. That means that the transition from terrestrial animals to fully aquatic animals took about 12 million years.
