What two recurring events in Earth’s history have an impact on the carbon cycle?
inessss [21]
The carbon cycle is affected by a variety of factors, and happens through different processes. The processes can be divided into two, which are biological processes and geological processes. The biological aspect covers the use and production of carbon by living organisms. The geological aspect covers physical processes such as volcanic eruptions, and weathering of rocks, which may result to release of carbon back to the atmosphere. However, both of these aspects can be affected by recurring events in Earth's history. One is the switching between glacial and interglacial periods, and the other one is the seasonal changes. Glacial periods can lead to lower temperatures and lower carbon levels in the atmosphere. In contrast to this, warmer interglacial periods result to higher carbon levels primarily due to an abundance of life. Seasonal changes have a similar effect that can be observed at a shorter time. Human activities such as burning of fossil fuels and deforestation may also bring changes to the carbon cycle.

Serous membranes line certain cavities within the anterior body cavity. <br> a. true <br> b. false
crimeas [40]

Serous membranes line certain cavities within the anterior body cavity. This statement is FALSE.

Serous membrane, also known as serosa in anatomy, is a silky tissue membrane made of mesothelium that lines the interior of bodily cavities and their contents. It secretes serous fluid to permit greased sliding motions between friction surface. Organs housed in body cavities that don't open up to the outside are covered by serous membranes that line the body cavities. The epithelium secretes a thin coating of serous fluid that coats serous membranes.

An indication of a serous membrane is the lining of the thorax. The pleura is the name for the serous membrane found in the thorax. The visceral pleura, the innermost layer, is on the lungs, whereas the parietal pleura, the outermost layer, is on the interior layer of the thorax.
