<span>a. What is one adaptation of a mangrove tree species that allows it to survive in its environment?
Answer: </span><span>Two key </span>variations they need are the flexibility<span> to survive in </span>wet<span> and </span>hypoxia<span> (no oxygen) soil, </span>and therefore the<span> ability to tolerate </span>briny<span> waters. Some mangroves </span>take away<span> salt from </span>briny water<span> waters through ultra-filtration in their roots.</span>
Answer: The correct answer is- B) Ecosystem.
Ecosystem can be described as a group of living organisms present in a particular area that are interacting with each other as well as the non living components of that environment.
In other words, it is the interaction between biotic ( living such as plants and animals) and abiotic ( non living such as temperature, air, water) components of an environment.
Example- Pond ecosystem, lake ecosystem.
Answer:
Use a head tilt (tilting the head backward) and chin lift to prevent the tongue from obstructing the upper airway, and look for the foreign body that is causing the obstruction.
Explanation.
The backward head tilt and chin lift will prevent the tongue from obstructing airflow.
If the foreign object can be seen and removed, do so. Usually, it is not wise to use the fingers unless the foreign object is visible and accessible.
The next step is to perform CPR because the patient is unresponsive.
Answer:
A) 6
Explanation:
Complex III of the electron transport chain transfers four protons across the membrane during aerobic respiration, per pair of electrons. In the other hand, complex IV is responsible for transporting two protons (per pair of electrons) across the membrane.
If the given compound injects a pair of electron into complex III, four protons will accumulated due to complex III activity and then two more protons as these electrons move forward to complex IV. This means a total of 6 protons being transported to intermembrane space.
