It would be most likely Harm
1) They are both Eukaryotic cells.
2) They lack cell wall.
Eukaryotic cell are cells that have a nucleus enclosed within membranes. Also, there are numerous membrane bound organelles which includes Golgi apparatus, mitochondria, Endoplasmic reticulum and Chloroplast.
Cell wall is rigid in nature and semi-permeable protective layer found in cells. They are positioned next to the cell membrane in most fungi, bacterial and plant cells but absent in Animal cells. Furthermore, they perform many important functions in the cell which includes protection, structure and support.
However, both human being and Ameoba have Eukaryotic cells and lack cell wall.
Answer:
Physical Change:
- Boiling water
- Breaking a pencil
- Water evaporating
- Denting a car door in an accident
- Tearing paper
- Ice melting
- dissolving
Chemical Change:
- Something rusting
- photosynthesis
- metabolism/digestion
- Nuclear power [atoms are arranged differently]
- Smashing paper with two metal balls, burns paper
- Electricity in water, breaks H2O into H2 and O2
-----
physical change is when there is only physical change occurring--and it can typically be undone easily,
whereas chemical change is when there is chemical change--which changes the chemical properties of something, which cannot be undone simply.
hope this helps!!
Members of phylum Porifera are commonly known as spongs. They are generally marine and mostly asymmetrical animals. These are primitive multicellular animals and have cellular level of organization (lacks tissues). These Organisms (belonging to phylum Porifera) lacks most of the structures that are present in multicellular organisms like digestive system, respiratory system, Brain etc
Body of Spongs are made up of spicules or spongin fibers and these organism contain a water canal system which helps them in digestion, reproduction and catching their food in marine habitat.
