The nurse should respond BY APPLYING GENTLE PERINEAL PRESSURE.
Application of gentle perineal pressure will prevent the excessive rapid expulsion of the foetus head which can cause perineal laceration in the mother.
Answer:
(a) Phosphatases remove the phosphate from GTP on GTP-binding proteins, turning them off
Explanation:
- A molecular switches are molecule that can be reversibly shifted between two or more stable states.
- The molecules may be shifted between the states in response to environmental stimuli, such as changes in pH, light, temperature, an electric current, micro-environment, or in the presence of ions and other ligands.
This is a process called transcription and translation.
Information to synthesize a particular protein is found in DNA in the cell nucleus. This information is copied (transcribed) onto messenger RNA or mRNA in short. The copying process is called transcription.
mRNA then leaves the nucleus and enters the cytoplasm where it attaches to a ribosome. Transfer RNA or tRNA then begins to read (translate) the information on the attached mRNA. This is the process of translation.
tRNA then fetches amino acids that correspond to this information and brings them to the ribosome where they are linked together into a chain. This chain of amino acids is the primary structure of the protein.
Photosynthesis in algae cells
Ecosystems were able to maintain themselves by cycling the
nutrients and energy obtained from external sources. The flow of energy through
a food chain is known as energy flow. At tropical level, solar energy is used by the primary producers to produce organic plants materials through photosynthesis.
