Answer:
two nucleotides are deleted
Explanation:
Frameshift mutations arise when the normal sequence of codons is disrupted by the insertion or deletion of one or more nucleotides, provided that the number of nucleotides added or removed is not a multiple of three.
Because two nucleotides are deleted (2 is not divisble by 3), it would be a source of a frameshift mutation.
Hope this helped! :^)
Answer:
The stratosphere
contains the ozone layer
,
is used by airplanes,
has strong, steady winds
, and
increases in temperature as altitude increases
.
Explanation:
The stratosphere is the atmospheric layer between 10 km and 50 km above the Earth's surface.
It includes the ozone layer, which is at an altitude of about 20 km.
It has strong, steady winds that can reach as high as 220 km/h.
Passenger aircraft generally fly in the lower levels of the stratosphere, at altitudes of about 10 km to 12 km.
Temperatures increase with altitude, from -50 °C at 10 km to -3 °C at 50 km.
A is wrong. The mesosphere (altitude 50 km to 85 km) is the coldest of the atmospheric layers, with temperatures as low as -90 °C at 85 km.
