At stage 3, it is most difficult to tell the embryo apart. This is because There are a lot of similarities at this stage and the distinguishing features have not developed yet.

Each embryo has some type of tail bone, whether it may or may not be used when actually born.

This can be used to support evoultion because the similarities clearly and visibily show a common ancestor between embryos. Because of their obvious similar traits, embryos must share ancestral DNA that they evolved from.

How is the reproductive rate of marine mammals
related to their status in regards to extinction?

Answers

Answer:

The fewer fish the less that can reproduce.

Explanation:

marine mammals with a slower reproductive rate are especially sensitive to disturbance , environmental changes and anthropogenic sources of stress because when populations of these organisms decline, recovery is especially slow . it takes a significant amount of time for these animals to reach reproductive maturity and they are commonly heavily invested in raising only one or two young ones every two to three years on average . therefore , populations of marine mammals with slow reproduction are in imminent danger when multiple sources of envirnmental pressure are acting in tandem over an extended period of time . The fewer fish the less that can reproduce.

More the reproductive rate, lesser the extinction and lesser the reproductive rate, more is the extinction.

What is reproductive rate?

The reproduction rate measures the conditions under which generations are replaced. This calculation can be made taking account of mortality (net reproduction rate) or without mortality (gross reproduction rate).

What is extinction?

Extinction is a situation in which something no longer exists.

When the reproductive rate of marine mammals will be less, they will not be able to cover up the loss/death of their species caused by any reason and will ultimately lead to extinction.
