Answer:
An aquaculture company called AquaBounty Farms has produced the first transgenic animal intended for human consumption: Atlantic salmon with two donor genes from other fish. The donated genes keep the transgenic salmon growing year-round, instead of taking a winter break, so they reach adult size faster than normal.
Explanation:

Answer:
The root mean square speed of O2 gas molecules is
<u>519.01 m/s</u>
<u></u>
Explanation:
The root mean square velocity :



Molar mass , M
For He = 4 g/mol
For O2 = 2 x 16 = 32 g/mol
O2 = 32/1000 = 0.032 Kg/mol
First calculate the temperature at which the K.E of He is 4310J/mol
K.E of He =


K.E of He = 4310 J/mol


<u>Now , Use Vrms to calculate the velocity of O2</u>




Answer:
Presence of water molecules
Explanation:
Temperature decreases with an increase in altitude. At sufficiently high altitudes, the air is much colder than the air on the surface of the Earth. Water vapor has a low density and is capable to rise until it gets into a medium with a significantly low temperature and pressure to condense and produce water droplets out of water vapor. Those droplets then form clouds.
<span>The earth's crust is primarily composed of a mineral named feldspars. Feldspars are the most common mineral by a margin of 30% more than the second most common mineral, quartz. Together, both of these minerals make about 50% of our Earth's crust.</span>
