Answer:
The populations are isolated and thus do not interbreed.
Explanation:
Answer:
This question lacks options, options are:
a) indirect
b) mosaic
c) determinative
d) regulative
e) direct.
The correct answer is d.
Explanation:
The egg (ovum) like the embryo during the first embryonic divisions, do not possess any sign of polarity. This development mechanism can be called regulative development(in contrast to the mosaic model) since the fate of the cells that originate is not fixed and can be modified during development. In regulative embryos, part of the embryo can be removed and the remaining cells can compensate for the loss and give a complete individual as the final product.The strongest evidence that continues to support this regulatory model is based on the plasticity or potential that mammalian cells possess before implantation. It is known that the blastomeres produced by the first divisions can be replaced with each other or even can be eliminated without apparently altering the embryonic development and therefore they are equivalent (without polarity).
Answer:
golgi tendon and muscle spindle
Answer:
<u><em>Starfish</em></u> reproduce every winter by ejecting there eggs into the water, since they only live on average 35 years they reproduce about 35 times in their lifetime. Only a couple of the eggs will fertilize and turn into a Starfish.
<u><em>Hippos</em></u> are the only mammals in Africa that reproduce in water, Hippos reproduce in May and through June. Hippos usually live to around 40 to 50 years, and most hippos through May and June reproduce more than one time.
Explanation:
Hippos strategies of reproducing are better than Starfish.
