Despite having gills, anabantoids can still drown if it does not have access to the surface.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Anabantoids, despite having gills, can still drown if they do not have access to the surface. This is because anabantoids, such as labyrinth fish, have a specialized organ called the labyrinth organ that allows them to breathe oxygen from the air. Without access to the surface, they cannot breathe and may suffocate, leading to drowning. Therefore, the statement that anabantoids can drown despite having gills is true.Rate this question:

Which of the following fish are "bentho-pelagic"?
- A.
Synodontis catfish
- B.
Various "shark minnows"
- C.
Loracariidae Catfish
- D.
Corydoras
Correct Answer(s)
A. Synodontis catfish
B. Various "shark minnows"Explanation
Bentho-pelagic fish are those that inhabit both the benthic (bottom) and pelagic (open water) zones of a body of water. Synodontis catfish and various "shark minnows" are both examples of bentho-pelagic fish. These fish are able to swim and feed in the open water column, but also spend time on or near the bottom. This allows them to take advantage of different food sources and habitats within their environment. Loracariidae Catfish and Corydoras, on the other hand, are not classified as bentho-pelagic fish as they primarily inhabit the benthic zone.Rate this question:

- A.
CRISPR Cas9
- B.
CD4
- C.
Glycine
- D.
Cytosine
Correct Answer
A. CRISPR Cas9Explanation
CRISPR Cas9 is the correct answer because it is a protein that can be used to modify or edit genes for genetic modification of fish. CRISPR Cas9 is a powerful tool that allows scientists to target and modify specific genes, making it a key component in genetic engineering and gene editing techniques. It works by using a guide RNA to direct the Cas9 protein to a specific DNA sequence, where it can then cut the DNA and introduce desired changes. This technology has revolutionized the field of genetic engineering and has numerous applications in various fields, including agriculture and medicine.Rate this question:
