Answer:
churning of the stomach contents.
Explanation:
When food is moved to the back of the mouth by the tongue (deglutition), it does not cause the churning of the stomach contents.
The churning of stomach contents occurs when the bolus from the mouth has entered through the lower esophageal sphincter into the stomach. Churning is the mixing of the bolus with digestive juices containing acids and enzymes secreted from the stomach lining.
Answer:

Answer:
Budding cells formed by the Saccharomyces are through "Cytokinensis"
Explanation:
Cytokinensis helps the budding cells of the Saccharomyces to get splitted over two new cells. These buds raise, throughout its cell cycle and afterwards leaves its mother cell while mitosis been completed. Budding of the yeast makes up an perfect model for the creature to study the meiosis. Diploid yeast can be prepared by making it undergo through meiosis in absence of nitrogen which will lead to the generation of an ascus along with 4 haploid cells. Due to this the property of the meiotic products can also be studied.
Answer:
Fossils provide direct evidence of evolution. They show the changes of animals from ancient organisms to present form. Fossils are the preserved remains of earth layers. There are 4 types of fossils-
Original fossils that are not very old. e.g. teeth, skeleton, shells.
Frozen fossils
less permanent fossils
casts, molds, and prints - wings, skin, leaves, etc.
The fossils show the adaptive radiation in horses, humans. The transition fossils form the connecting link between different groups such as fish and amphibians, reptiles and birds, etc.
e.g. Archeopteryx is the connecting link between the reptiles and birds.
The modern horse Equus have several ancestor species, we came to know from the fossil records.
The fossil record shows the evolution of humans and their ancestors.
If adding more HCl will double the original amount you get concentrated HCl I think
