Microorganisms can be divided into two groups:
1. Archea
• Archea are prokaryotic unicellular organisms without cell nucleus or other membrane bound-organelles.
• Their membrane is built from ether lipids, which differs them from bacteria’s cell membrane.
•
2. Bacteria
• Bacteria are also unicellular prokaryotic organisms.
• Bacterial cell membranes are made from phosphoglycerides with ester bonds. Bacterial genome is in a form of circular chromosome.
• They reproduce by binary fission or by budding.
Besides, prokaryotes (Archea and Bacteria) a large number of eukaryotes are also microorganisms. Unicellular eukaryotes contain organelles such as the cell nucleus, the Golgi apparatus and mitochondria. Usually, they reproduce asexually by mitosis. An example of eukaryotic microorganism is Protist.
Answer:
proline
Explanation:
coded for the polypeptide poly-proline. Therefore, the codon AAA specified the amino acid lysine, and the codon CCC specified the amino acid proline.
Answer: Lipoproteins; site of utilization
Amber ate a meal high in fat. Initially, after digestion and absorption, the different types of fat will be packaged into lipoproteins and carried to the site of utilization
Explanation:
Lipoproteins are proteins that formed complex with lipids (fats). After a meal rich in fats, they help to transfer lipids from the site of absorption of the site of utilization. Based on the their density, lipoproteins are classified as:
- very low density lipoproteins (VLDLs) which transports triglycerides
- low density lipoproteins (LDLs) which transports several kinds of fats
- high density lipoproteins (HDLs) which transports cholesterol
- very high density lipoproteins (VHDLs) which transports phospholipids
B
Explanation:
It occurs when water dissolved with salts seeps into the cracks of a rock. When the water slowly evaporates it leaves behind crystals of salts. When the rock is heated, the salts also expand and create pressure within the cracks, widening them and causing the rock to split.
