Explanation:
Continental drift is the theory which states that the continents of the earth moved away from each other over a period of time. It is believed that this theory was opposed by many scientists because they stated that there weren’t enough evidence of mechanism to prove the drift between the continents.
However, it was also rejected because this theory opposed many ongoing geological theories like geosyncline theory, uniformtarism theory even when sufficient evidences were there to prove the continental drift theory.
Light energy is transferred to a chlorophyll reaction center where electrons become energized.
- A protein in the electron transport chain, pumps H+ ions from the stroma into the thylakoid space
- Electrons from the electron transport chain close to photosystem II replace the elctrons lost in photosystem I
- Electrons from Photosystem I become energized and escape photosystem I and move down the second electron transport chain.
- H+ ions flow down the concentration gradient through a channel in ATP Synthase, releasing energy in the process
- Electrons move down the electron transport chain, releasing energy
- Electrons move to an electron acceptor in the electron transport chain and electrons in photosystem II are replaced by the splitting of a water molecule
- Photosystem II receives photons in the form of light energy
- Water is split to replace the electrons in photosystem II
- At the end of the electron transport chain, the energized electrons and an H+ ion are used to reduce NADP+ to NADPH
- ATP uses energy to add a phosphate to ADP forming ATP
The following injury may require a tracheostomy, according to the statement.
The best option is A.
Laryngeal injuries can be treated with intubation, cricothyrotomy, or tracheostomy. A bronchial damage is treated by bronchoscopy and conceivably with surgical repair. Esophageal injuries require immediate surgical treatment. Gastric tube insertion and surgical repair are required for the treatment of a diaphragmatic injury.
<h3>What is a tracheostomy?</h3>
A tracheostomy is a hole drilled into the front of the neck that enables tracheal intubation. If necessary, the tube can be connected to a ventilator, a mechanical breathing device, and an oxygen source.

Answer:
Start your seeds off indoors - they need plenty of warmth to germinate.
Fill a seed tray or some 10cm pots with moist seed compost and flatten down.
Sow a few seeds on top and cover with a fine sprinkling of vermiculite or compost.
Place in a propagator at a temperature of 18-25C (64-77F).
