pH value of these kind solution in 7
Answer: b) organelles must interact with each other to synthesize and transport proteins.
Explanation:
The DNA is a genetic material which is converted into mRNA by the process of transcription in the nucleus. The protein synthesis takes place in ribosomes where the translation of mRNA to protein takes place. The proteins are transferred to rough endoplasmic reticulum for the packaging into membrane structures called as cisternae. The proteins are transferred to the golgi apparatus where they are modified, sorted and packed in vesicles. The vesicles take away proteins outside the cell. In golgi apparatus the proteins are tagged with the aminoacids so that they can be targeted to the particular cell.
Biology is the study of the earth therefore it is false
Answer:c. Steroids/cholesterols and phospholipids
Explanation:
The cell membrane structure exhibit a fluid mosaic model due to the presence of two types of membrane lipids these are phospholipids and sterols like steroids/cholesterols.
A phospholipid is a kind of lipid that is made up of glycerol, two fatty acids in tail and a head group associated with the head group. The biological membrane forms two layers of phospholipids with their tails that points inwards and the arrangement is called as the phospholipid bilayer.
The cholesterol is the another membrane lipid in the cell membrane. It is composed of fused carbon rings present along the side of phospholipids.
