Hello! Allow me to help!
Your question: Can the atmosphere change in its composition?
My answer: Our atmosphere is made up of many different gases. The most common gases are nitrogen, oxygen and argon. But, the exact amount of each gas is always changing.
Why is my answer correct? Good question! Allow me to explain: Tropical deforestation not only has a large impact on the carbon cycle and climate, but also affects the chemistry of the atmosphere. Together with the carbon cycle and weather patterns land use can affect the concentrations of greenhouse gases like methane and ozone.
Over a vast amount of time, millions of years, the earth gradually cooled. When the temperature dropped enough, water vapor condensed and went from a gas to liquid form. This created clouds. From these clouds, the oceans formed and the oceans absorbed a lot of the carbon dioxide in the atmosphere.
Changes in atmospheric composition and the rest of the climate system would include temperature, rainfall, and humidity, which would affect the economic importance, geographical distribution, and management of diseases effecting crop production.
Hope this helps! UwU

Answer:
8 different combinations of gametes can be produced by this mosquito, assuming no homologous recombination between chromosomes
Explanation:
The mosquito has 6 chromosomes. This means that means it has 3 pairs of homologous chromosomes. Basically, we can assume the number of different gametes by 2 to the power of 3 as their are 3 homologous pairs. This means 2×2×2 which will be equal to the amount of eight. Hence, eight different combination of gametes will be produced.
1- they can be used as domestic fuel for cooking instead of kerosene or firewood that contribute to pollution
2-they can also used to generate electricity in rural areas as these areas has not enough resources of electricity
The thoracic region receive sympathetic innervation from the middle and inferior cervical ganglia.
The cervical sympathetic trunk is the portion of the sympathetic trunk located to the left and right of the cervical spine, this trunk extends from the entrance of the thoracic wall to the base of the skull.
- It is made up of 3 ganglia: the superior ganglia made up of the first 3 cervical ganglia; the middle ganglia made up of the 4th cervical ganglion and the inferior ganglia made up of the last 4 ganglia.
- These ganglia are responsible for the sympathetic innervation of the upper extremities, the viscera of the thoracic cavity and that of the organs of the abdominal cavity.
Therefore, we can conclude that the thoracic sympathetic chain is made up of ganglia that innervate the thoracic region.
