Answer: D. Estuaries
Explanation:
Organisms adapted to surviving in water with a wide range of salinity are most likely to be native species in estuaries.
Organisms adapted to surviving in water with the widest range of salinity would most likely be native species in estuaries. Estuaries are coastal areas where saltwater and freshwater mix, creating fluctuating levels of salinity. Many estuarine plant species are halophytes, which can tolerate salty conditions, while animals in estuaries have developed behavioral adaptations to function in this changing environment.

Answer:
True
Explanation:
The question is incomplete as it lacks multiple options. The options are as follows:
Notify the primary healthcare provider
Check the chest tube for patency
Inspect the incision for bleeding
Auscultate the left lung
Answer:
Auscultate the left lung
Explanation:
Pneumonectomy may be defined as the surgical procedure of the removal of lung or its part. The pneumonectomy is mainly performed in case of the lung tumors.
The auscultation is the procedure of listening different sounds of the hear and lungs. The auscultation is important as after the surgery the airway obstruction might occur and may also cause the trachea deviation. The proper lung sound do not require any medical procedure but abnormal sound require emergency medical procedure.
Thus, the correct answer is option (4).
A
All cells contain ribosomes that conduct protein synthesis.
B
Cells contain genetic information in the form of DNA.
If isolated from a eukaryotic cell, mitochondria can no longer survive and reproduce on their
own.
If isolated from a plant cell, a chloroplast can survive and reproduce on its own.
Answer:
C. If isolated from a eukaryotic cell, mitochondria can no longer survive and reproduce on their own.
Explanation:
The endosymbiotic theory proposes that early eukaryotic cells evolved from endosymbiotic interactions among prokaryotic cells. This theory states that mitochondria and chloroplasts were once primitive bacterial cells that were ingested by large anaerobic prokaryotic cells, and then these cells benefited from living and working together. The most important lines of evidence that support this theory are that mitochondria and chloroplasts contain their own genetic material (circular DNA) and their own protein biosynthesis machinery (ribosomes).
The statement supporting the endosymbiotic theory claims chloroplasts can survive and reproduce on their own when isolated from a plant cell. This suggests these organelles, once independent prokaryotic cells, retain certain autonomous features despite integration into the eukaryotic cells.
The endosymbiotic theory proposes that certain organelles in eukaryotic cells, such as mitochondria and chloroplasts, originated as independent prokaryotic cells that were engulfed by a host cell. This event allowed a symbiotic relationship to develop, which subsequently led to the development of eukaryotic cells. The option that best supports this theory is: 'If isolated from a plant cell, a chloroplast can survive and reproduce on its own.'
This statement suggests that chloroplasts, like the bacteria from which they evolved, maintain some ability to live independently. Yet, although they contain their own DNA and ribosomes (symbols of their independent past), they are no longer 'free-living'. Similarly, mitochondria are also likely to have been independent entities because they too contain their own DNA and ribosomes. However, having been integrated into the host cell, they can no longer survive on their own, contrary to what might be inferred from the third option. The first and second options simply represent characteristics of all cells and provide no specific support for the endosymbiotic theory.

b. under their feathers
c. on their wings
d. on their feet
The correct answer is d - on their feet.
The scales found on birds are made of keratin, the same material that forms the beak, claws and spurs.
The scale are mainly found on the toes of the bird and also on the metatarsus. Some may be found a little up the ankle.
The scales of birds were thought to be similar to those found on reptiles and mammals, but research done in recent times has shown they are somehow different.
