Answer:
translation
Explanation:
occurs at the ribosome, which consists of rRNA and proteins
Answer:
B
Explanation:
The fatty acid tails of phospholipids are hydrophobic – meaning they are ‘water-hating’. This is why they are in the middle of the bi-lipid layer of the cell membrane 'hiding' from the 'watery' environment of a cell. This poses a challenge in the diffusion of large and charged molecules across the membrane -such as sodium ions. Such molecules need transmembrane protein channels to help them cross the membrane. These are called integral proteins because they are part and parcel of the cell membrane. The cell membrane, in addition, also has glycolipids and glycoproteins on its surface that are significant in the identification of the cell by other cells.
Answer:
photosynthesis
Explanation:
Chlorophyll a absorbs the wavelengths of violet-blue and orange-red light and functions as a primary electron donor during the election transport chain in photosynthesis. It also functions in transporting energy to the reaction center where P680 and P700 are located.
This is a false statement.
Natural resources are those substances that occurs naturally which are used by human being for various needs.
Example of natural resources that need sustainable practice include:
- Forest
- wild life
- mineral resources
- water
- soil
Sustainable use of these natural resources is the wise or judicious or intelligent use of these resources to ensure their availability and preserve the quality of the environment.
Therefore, using natural resources is considered a sustainable practice because most natural resources are in limited supply and can be degraded or depleted
