Biology
1 answer:
Mariulka [41]3 years ago
6 0

Answer:

D. water is able to hold dissolved oxygen

Explanation:

Dissolved oxygen (DO) can enter water by <em>diffusing</em> across the surface of water from the air, or as a <em>byproduct of photosynthesis</em> by other aquatic organisms like plants and algae. Each aquatic organism, like land-dwellers, has specific oxygen requirements. Fish use DO for the process of respiration, where they obtain oxygen from the surrounding water using their gills. Anoxic conditions, where oxygen levels are low usually result in significant deaths in fish populations.

Which chromosomal defect is caused when part of a chromosome breaks off and reattaches backward on the same chromosome?
LiRa [457]

The right answer is inversion.

Inversion is a genetic mutation characterized by the end-to-end reversal of a portion of chromatid on a chromosome.

In other words, it is a double break then it is replaced after rotation of 180 ° of a chromosome segment (backward insertion).

We distinguish :

Paracentric inversions:  The centromere in the chromosome is not included in the inversion.

Pericentric inversions:  The centromere is included in the inversion which transforms a metacentric chromosome into an acrocentric chromosome.
