Explanation:

Selective breeding or artificial breeding is a process that allows humans to select parents in plants and animals that have desirable traits. Such parents are bred to produce offspring that have desirable traits from both parents. Humans have bred many species of plants and animals to improve the quality of plant and animal yields in terms of crops, milk, meat, eggs, and other derivatives.

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.

Explain why the scientific method may not follow the exact same step each time through the process.

kherson [118]

Answer:

The scientific method may not follow the exact same steps each time because experiments are different. Some may have many more steps to follow to reach the conclusion, while others may take less time and have less steps. For example, some experiments may require a chart or graph of the results to be made, while others do not need that to display the results
