Answer:
Migrate through blood vessels
Explanation:
White blood cells have the ability to perform diapedesis. Diapedesis refers to the emigration of white blood cells through the blood vessels. During the process, white blood cells move along the endothelium of blood vessels and stick to it. The white blood cells squeeze between the endothelial cells to migrate out of the blood vessels.
In this way, white blood cells can reach the site of infection or move from blood to the interstitial fluid to perform immune functions. The ability to migrate in and out of the blood vessels allows the phagocytic neutrophils and macrophages to arrive at the site of pathogen entry, basophils arrive at the site of inflammation to perform their respective functions.
Answer:
active; prokaryotes
Explanation:
Active transport can be defined as the movement of molecules across cell membranes against a concentration gradient, i.e., from a region of low concentration to a region of high concentration. Group translocation is a specialized type of active transport observed in prokaryotic cells. In group translocation, the transported substance is chemically modified during its movement, thereby the cell membrane becomes impermeable to this substance once it is within the cell. In bacteria, the phosphotransferase system is a type of group translocation that uses phosphoenolpyruvate (PEP) as a source of energy to transport sugar molecules into the cell.
Answer:
It tricks the child's mind to feel safe
Explanation:
YOUR ANSWER IS tRNA because the mRNA sends out a message to the tRNA and the tRNA brings back the appropriate amino acid but if the tRNA where to bring back the wrong the protein could fold incorrectly.
