Answer:
A
Explanation:
The Endoplasmic reticulum is now responsible for pumping cytoplasmic ATP across the plasma membrane. the Proteins could be send to the Golgi apparatus for packaging and from there to the nucleus. The ER is responsible for synthesizing these proteins because of its proximity to the nucleus
Double and single strands

Explanation:
Biogeochemical cycles are pathways by which nutrients flow between the abiotic and abiotic compartments of the Earth. The abiotic portion of the Earth includes the lithosphere (the geological component of the Earth) and the hydrosphere (the Earth’s water).
Ecosystems rely on biogeochemical cycles. Many of the nutrients that living things depend on, such as carbon, nitrogen, and phosphorous are in constant circulation.
Essential elements are often stored in reservoirs, where they can be taken out of circulation for years. For example, coal is a reservoir for carbon.
Humans can affect biogeochemical cycles. Humans extract carbon and nitrogen from the geosphere and use them for energy and fertilizer. This has increased the amount of these elements in circulation, which has detrimental effects on ecosystems.
Answer:
The respiratory system enables oxygen to be taken into the body and it ensures the movement of carbon dioxide outside the body.
When we breathe in, our diaphragm moves downwards. Air enters the lungs through the larynx where it is filtered. from there it travels down the trachea, to the bronchi and then to the bronchioles. Alveoli are the air sacs where the exchange of gases takes place between the lungs and the blood. The alveoli pass oxygen into the blood and the blood passes carbon dioxide to the lungs. As we exhale, the diaphragm rises upwards causing the air to flow from the trachea to the larynx and exhalation from the mouth.
