Answer
Hi,
Geochemical cycling is the flow of substances or elements that occurs between reservoirs in Earth’s atmosphere, the water bodies and the lithosphere.
Explanation
A geochemical cycle is normally the path followed by chemical elements in the surface and crust of the Earth. The cycle starts with the crystallization of magma in the lithosphere at the surface or at depth. Weathering and surface alteration follows breaking down igneous rock that will be transported and deposited as sediments. The sediments become lithified and later metamorphosed until melting happens to form new magma.
Best wishes!

Answer:
B. functional body cavity lined by tissues derived only from endoderm
Explanation:
From the word "Pseudo" means false i.e something that is not true or literally acting in place for a particular real subject.
Coelom on the other-hand is an fluid-filled hollow cavity that act as the skeletal structure for an organism. They act helps serves as cushion effects for the organism.
Ceolomates are organism that have ceolom and the body tissues are derived from the mesodermal layer that lined the body cavity of organism possessing these ceolom.
But in pseudocoelomate they do not have a true ceolom, but there functional body cavity lined by tissues derived only from the endoderm.
Explanation:
In a general way cells communication to each other through chemical signal which can be regarded as their language. Hormones, compounds and neurotransmitters behave like words that are spoken because they tell the cell about its environment and they also pass messages to the cells and the cell acts on the signal received. Each cells has receptors through which they detect different actions to be taken or signals that needs to be responded to, so they are always underground biological conversations.
Answer:
ligament of Treitz
Explanation:
On the basis of anatomy and functions, the small intestine is divided into duodenum, jejunum, and ileum. Duodenum is the first part of the small intestine that starts at the pyrolic sphincter and ends at the suspensory ligament of Treitz. Beyond the suspensory ligament of Treitz, jejunum, and ileum are present without any anatomical distinction to delineate them from each other. Also known as suspensory ligament of the duodenum, the ligament of Treitz is a thin band of muscle and holds duodenum and jejunum in place.
