Answer:

We can conclude that the fish is Sturgeon.  

Explanation:

We need to identify the result of a fish with a single dorsal fin, no fin on its back near the tail, and an asymmetrical tail.

The problem mentions the following dichotomous key:

1. (a) Has a single dorsal fin ® 5 (b) Has a double dorsal fin ® 2

5. (a) Has a small fin on back near tail ® 6 (b) Has no fin on back near tail ® 7 6. (

a) Has barbs near the mouth ® Catfish (b) Does not have barbs near the mouth ® 10

7. (a) Tail is asymmetrical ® Sturgeon (b) Tail is symmetrical ® 8

In the first step, the fish we need to study has a single dorsal fin. According to the key number 1. (a) Has a single dorsal fin ® 5 We should go to five-step.

After that, we know that this fish has no fin on the back. Taking into account key number 5. (a) Has a small fin on the back near tail ® 6 (b) Has no fin on the back near tail ® 7 We should go to number seven.

The last information we have about this fish is that it has a tail asymmetrical. 7. (a) Tail is asymmetrical ® Sturgeon. As the final result, we can conclude that the fish is Sturgeon.

Finally, we can conclude that the fish is Sturgeon.

Why does a female’s cervix dilate prior to delivering a baby?
cluponka [151]

Effacement: The cervix – which is normally long and thick, measuring about 1-2 inches, starts to get shorter and thinner. This process is known as effacement. As the cervix gets more and more effaced, it gets shorter and shorter and “pulled up” into the lower part of the uterus.

Dilation: At the same time, the cervix softens and begins to open up – known as dilation. This widening, allows a smooth passage for the baby’s head and the rest of the body from the uterus into the vaginal canal.
