Which technology are environmental scientists using to photograph poaching activities in africa? a. unmanned aerial systems (uas) b. gel electrophoresis c. environmental dna (edna) surveillance d. acoustics

Option A. Unmanned aerial systems (UAS)

Explanation:

Unmanned aerial systems are cheap method of monitoring an area with radius of thousands of acres/km.  

These systems work by using infrared light which are able to capture images and videos in night also.  

Due to this, UAS  is now being used an essential equipment in anti-poaching missions where it assists in doing Bird’s nest surveys, tracking activities of animals, automated species identification etc.  

 Being cheaper makes it financially suitable for African countries.

Thus, option A is correct.

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.
