Answer:
first
Explanation:
a. True
b. False
B. They have a true body cavity.
C. They have two germ layers.
C. They have two germ layers.
Members of the phylum Porifera are not considered diploblastic because they do not have two germ layers. Instead, they have a unique level of organisation where their cells do not form tissues or organs. The term 'diploblastic' correctly applies to organisms like jellyfish or sea anemones that have two germ layers producing various tissues and organs.
Members of the phylum Porifera, often referred to as sponges, are not considered diploblastic because they do not have two distinct germ layers. Instead, they possess a unique level of organization in which their cells do not form tissues or organs. Confusingly however, they do have two layers of cells, but these do not equate to the germ layers seen in true diploblastic organisms like cnidarians.
In a true diploblastic organism, such as a jellyfish or sea anemone, the two germ layers - the ectoderm and endoderm, produce the various tissues and organs of the organisms. The jellyfish's tentacles and mouth, for instance, are produced by the ectoderm, while its digestive cavity is produced by the endoderm.
So, the statement that clarifies the term 'diploblastic' with respect to members of Porifera is not accurately represented by any of the provided options, since they are not truly diploblastic. The closest would be 'C. They have two germ layers', but this is still not technically correct for the reasons mentioned above.

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.

The respiratory and circulatory system work together to deliver oxygen to body cells.
The respiratory and circulatory systems work together to deliver oxygen to body cells. The respiratory system is responsible for breathing in oxygen and expelling carbon dioxide, while the circulatory system transports oxygen-rich blood to the cells. Within the circulatory system, the heart pumps oxygenated blood through arteries to the body's tissues, where oxygen is delivered to the cells through capillaries.

Cell respiration occurs in animal cells and not plant cells.
Photosynthesis uses chemical energy as energy source, and cell respiration uses light energy.
Photosynthesis uses light as energy source, and cell respiration uses chemical energy.
Correct answer: Photosynthesis uses light as energy source, and cell respiration uses chemical energy
Photosynthesis is a light dependent process in which green plants and certain other organism convert light energy in to chemical energy. In this process sunlight is uses to to convert water and carbon dioxide into ATP molecule which are needed for growth.
Cellular respiration is metabolic process that occurs inside the mitochondria of the cell to convert biochemical energy which is derived from nutrients into ATP (Adenosine triphosphate) and removal of waste products.
Photosynthesis uses light as an energy source, while cell respiration uses chemical energy. Therefore option d. is the correct answer.
The correct statement that distinguishes photosynthesis and respiration is:
Photosynthesis uses light as an energy source, and cell respiration uses chemical energy.
In photosynthesis, plants convert light energy into chemical energy, specifically glucose. This process occurs in the chloroplasts of plant cells.
On the other hand, cell respiration is the process by which cells break down glucose to release energy in the form of ATP (adenosine triphosphate).
This process occurs in both plant and animal cells, specifically in the mitochondria.
Therefore, photosynthesis uses light as its energy source, while cell respiration uses chemical energy.
Therefore option d. is the correct answer.
