Answer:

pore

Explanation:

Sponges are simple multicellular organisms. They do have aggregate cellular level of body organization. All major body functions in the sponge such as exchange of gases, circulation, and excretion are carried out by diffusion between the cells located at the pore (opening) of the sponge and the water which passes through the pore.   All the cell present within the sponge take oxygen from water through diffusion. Similarly, carbon dioxide is released into water diffusion. The excretory product produced as a by-product as a result of the breakdown of protein is diffused out by individual cells into the water as it passes through the sponge.

<span>contractile vacuole

Contractile vacuoles are organelles that are responsible for excretion function. They perform osmoregulation which manages wastes, water and other needed materials in the cell. They are found in some prokaryoric organisms like the algae, protists, amoeba and other unicellular organisms.

Because the human embryo is able to split during early cleavage or blastocyst formation to produce two viable progeny, it is sai
juin [17]

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).
