Answer is B. Porifera
Members of the phylum porifera includes animals which lack tissues. These animals are also called sponges. These are the simplest multicellular animals. Even though they are multicellular, they do not have any tissues or organs. They have cellular level of body organization. Sponges are aquatic animals and water plays a major role in the feeding, exchange of gases and as well as excretion.
Answer: rough endoplasmic reticulum--b
Smooth endoplasmic reticulum--a,c,d
Explanation:The rough endoplasmic reticulum has numerous ribosomes attached to it. Thus it has a coarse texture.it is involved in the production of proteins. The ribosomes receives the messages to produce a protein from the messenger RNA, the ribosome the packs amino acid into proteins and transfers it to the rough endoplasmic reticulum.
The smooth endoplasmic reticulum does not have ribosomes attached.it is involved in the production of non-protein molecules eg lipids and fats.
It is an also important organelle for the metabolism of the cell.it helps in detoxification in the liver. It also stores calcium for use in the skeleton.The sarcoplasmic reticulum is an modified smooth endoplasmic reticulum
Answer:
1. lysosomes destroy unwanted material's
2. nuclear membrane determines what enters and exit the nucleus
3. cell membrane determine the type of material that enters or leave the cell
4. Golgi apparatus
5. golgi apparatus
Answer;
ATP.
The generation of ATP occurs by Chemiosmosis.
Explanation;
In the electron transport chain, hydrogen ions in the matrix space can only pass through the inner mitochondrial membrane through a membrane protein called ATP synthase.
As these protons move through ATP synthase, ADP is turned into ATP.
The production of ATP using the process of chemiosmosis in mitochondria is called oxidative phosphorylation.
