The key evolutionary development of animals seen for the first time in sponges is that of  Multicellularity.
Multicellularity means having or consisting of many cells or more than one cell to perform all vital functions. Sponge is a member of the phylum Porifera. It is a simple animal with any cells, but no mouth, muscles, heart or brain. It is any primitive multicellular aquatic animal that constitute the phylum stated above.

The key evolutionary development of animals seen for the first time in sponges is that of Multicellularity.    A Multicellular organism has a longer lifespan than an unicellular organism and since it has multiple cells, it can perform more functions.  Sponges do not have distinct circulatory, respiratory, digestive, and excretory systems – instead the water flow system  supports all these functions.

75% of the children will have the probability of being tasters. 25% will have the probability of being non- tasters.

Answer b)

There will be a 75% chance that their first child or their fourth child will be a taster.

The chances for every child will be the same because alleles assort independently during the time of gamete formation. Hence, the probability remains the same every time.

Answer c)

There will be a 25% chance for the first three offsprings to be non-tasters. 75% chances will be of them being tasters.

This is because the alleles assort independently each time during gamete formation. Hence, the chances will be the same every time.

A scientist was observing a specimen under a microscope. He obtained the specimen from pond water. He observed that the specimen
NNADVOKAT [17]

There are three ways you can solve this problem:

1.- You can guide yourself through knowledge, and therefore know the answer. There isn´t much to explain here.

2.- You can eliminate obvious options such as sarcodina or apicomplexa. Euglenoid isn´t an extremely obvious removal since it has a flagela, which can be mistook by a hairy-structure. But, if you do things correctly, obtaining your answer wont be a problem.

3.- You can do an etymologic-guess, which works really well in biology. If you guide yourself this way, you´ll bump into the answer quickly --> "cilio" means hair and according to the description the specimen was covered in hairy structures.

Hope it helped,
