Why do we care how bacteria reproduce? Conjugation is a huge problem for humans. In bacteria, conjugation can occur even between individuals of different species. The DNA on plasmids often allows bacteria to grow in the presence of antibiotics, drugs intended to kill them. When these plasmids are shared by conjugation and many different plasmids are accumulated, new strains of bacteria are created. These new strains can fight off many, perhaps all, known types of antibiotics. This is becoming a big concern in human health. Research multiple antibiotic resistance. Then, list a few ways in which human activities contribute to this problem.

the major parts of the digestive system:

salivary glands.

pharynx.

esophagus.

stomach.

small intestine.

large intestine.

rectum.

accessory digestive organs: liver, gallbladder, pancreas.

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.

i believe it is "they are not used up by reactions" as the answer to your question, text me back if this is correct because i just learned this.

what do the different brain waves do?

explanation:

brainwaves are produced by synchronised electrical pulses from masses of neurons communicating with each other. brainwaves are detected using sensors placed on the scalp. brainwave speed is measured in hertz (cycles per second) and they are divided into bands delineating slow, moderate, and fast waves.
