7)Flame lip of broth culture tube.
8) Sterilize the loop.
Explanation:
The aseptic technique is a s<u>eries of steps to prevent contamination during manipulations of cultures and sterile culture media</u>. A mastery of aseptic technique is required for maintaining pure cultures, as airborne contaminants are virtually everywhere. Picking an isolated colony and restreaking it is the main method for obtaining pure cultures from liquid samples containing several different organisms and is a common procedure in the microbiology laboratory. Other techniques for obtaining pure cultures have been developed that are especially suited for particular groups.
Answer:
De la glándula pitnitaria se encuentran las hormonas llamadas dopomina, que es impulsada por los hipodtalamas, la parte del cerebro directamente sobre la glándula pituitaria. La dopapamina restringe la proyección, por lo que cuanto más dopomilo haya, menos liberación se produce
Answer: The answers seem correct.
1. Active transport - the process in which energy is used to move the particles of a substance against a concentration gradient from a region where they are in lower concentration to a region whey are in higher concentration.
2. The answer chosen for #2 makes sense because energy is usually needed when you putting effort into doing an activity that includes some type of force. That means ions are using energy to be moved against the concentration gradient.
3. Volume makes sense for the last question since the cells are using a space (volume) to move material in and out by diffusion. The other options besides volume are unreasonable.
