<span>During ejaculation, the sperm is sent out from the epididymis into the deferent duct which then travels up the spermatic chord into the pelvic cavity. The first organ that sperm pass through is the epididymis ejaculatory duct . During this time rhythmic movements propel the sperm forward.</span>
Buildup of organisms means that the species number is pretty high.
Gradual change means that it was a slow, calm time to make the change.
I hope this helps!!
Muscular activity of its digestive system distorts the body wall should convince you that the organism is acoelomate.
<h3><u>
Explanation:</u></h3>
An animal that does not have body cavity refers to an acoelomate. It is in contrast with the eucoelomates which are the animals that have body cavity. The acoelomate will not have a cavity which is filled with fluid between the digestive tract and the body. Hence there will be a distortion of body wall by the muscular activity of the digestive system.
Some of the examples of acoelomate are Cnidaria,Porifera , Platyhelminthes, Placozoa ,Gnathostomulida.Nemertina and Mesozoa. The presence of pseudocoelom in which the body cavity will not be lined by the mesodermal cells are the Pseudocoelomate.
The ATP molecule is a high energy molecule. When a molecule of ATP breakdown, it produces chemical as well as thermal energy. The type of energy produced is mainly depends on the application for example, if the ATP breaks down to ADP, it produces thermal energy and if couples with a cellular process it produces chemical potential.
Our body needs energy to carry out cellular functions and the energy produced in a form of ATP is taken by cells to perform functions.
