Which of the following mutations would most likely be identified as a chromosomal translocation
snow_lady [41]

Answer: Structural chromosomal mutation

Explanation: In translocation, a small piece of chromosome is detached from one chromosome and is attached to another non-homologous chromosome. Translocation can be simple, shift or reciprocal.

Simple translocation involves single break in the chromosome. The broken piece gets attached to the end of the non-homologous chromosome.

In Shift translocation, the broken segment of one chromosome gets inserted interstitially in a non-homologous chromosome.

Segment from one chromosome is exchanged with a segment from another non-homologous chromosome simultaneously in Reciprocal translocation.

Most species of cyanobacteria are enclosed in a _____.
Natali [406]

Answer: mucilaginous sheath

Explanation:

These algae are known as "blue algae" because of their pigmentation or "cyanobacteria" because they are prokaryotes. Microbiologists classify cyanobacteria in the realm of Eubacteria. They are the only prokaryote algae. The cellular organization is prokaryotic, without nuclei or organelles. Respiration takes place at the level of plasmalemma and thylakoids. In the center (nucleoplasm), cells contain their genome and circular plasmids. Cyanobacteria often also have a mucilaginous sheath common to many trichomes.

These organisms contain several carotenoid pigments, particularly myxoxanthophyll, which does not occur in any other algae group. Some cyanobacteria are strictly phototrophic, others are optional: they are phototrophic when in the presence of light, but may grow in obscurity using an organic carbon source. Others can use a source of organic carbon as well as inorganic carbon, but only in the presence of light.

Which of the following is true of anabolic reactions? View Available Hint(s) Which of the following is true of anabolic reaction
puteri [66]

Answer:

Anabolic reactions use ATP and small substrates as building blocks to synthesize larger molecules.

Explanation:

Anabolic reactions are part of metabolic pathways that occur inside the living cells. Anabolic reactions always form complex molecules from simpler substances. The formation of glucose from relatively simpler CO2 and H2O during the Calvin cycle is an example of the anabolic pathway. During anabolic pathways, the metabolic energy of ATP hydrolysis drives the endergonic reactions. Therefore, anabolic reactions consume ATP. Calvin cycle uses the ATP produced during light reactions of photosynthesis.
