It is useless for living specimens of bacteria, and inferior for non-photosynthetic protists or metazoans, or unstained cell suspensions or tissue sections. Here is a not-so-complete list of specimens that might be observed using bright-field microscopy, and appropriate magnifications (preferred final magnifications are emphasized). Prepared slides, stained - bacteria (1000x), thick tissue sections (100x, 400x), thin sections with condensed chromosomes or specially stained organelles (1000x), large protists (100x). Smears, stained - blood (400x, 1000x), living preparations (wet mounts, unstained) - pond water (40x, 100x, 400x), living protists (40x, 100x, 400x occasionally), algae and other microscopic plant material (40x, 100x,…
F. For which of the organisms on the wet mount, if any, were you able to observe motility?…
Organism two is yeast, which is apart of the fungi kingdom, evident due to its small circular transparent cells. Organisms in the fungi kingdom are mostly multicellular eukaryotes that reproduce both sexually and asexually. Fungi are also heterotrophs, meaning they gain energy from the consumption of other organisms. Organism three is a Daphnia which is a common water flea with a transparent body. Daphnias are apart of the Animalia kingdom, making it eukarya. Organisms in the kingdom Animalia are also multicellular eukaryotes that are heterotrophs and reproduce sexually. Organism four is a paramecium which is a single-celled eukaryote with an evident nucleus in the center of the cell. Parameciums are apart of the Protista kingdom and are mostly unicellular eukaryotes. Organisms such as parameciums in the Protista kingdom also reproduce both sexually and asexually while also being both heterotrophs and autotrophs. Lastly, organism five, also known as Euglena, is a unicellular eukaryote that is also apart of the Protista kingdom. Euglenas also reproduce asexually and are…
KNOW IT j 1. Describe the cell theory. 2. Which of the following statements best explains why bacteria are considered living organisms?…
There was several amoeba shaped cells that varied in size. There were five somewhat darker areas that were circular in shape. There were also three large, oddly shaped areas that had very distinct edges.…
Bacteria are a single cell micro-organism that can only be seen from under a microscope. It lives off the nutrients from its surroundings.…
Chemosensory organs in many crustaceans including Hyalella azteca allow them to locate food and mates while entirely avoiding predators. When detecting environmental changes such as the change in chemicals such as salinity, many amphipods have tiny hair-like organs containing sensory cells called sensilla (Hallberg, 2011). These chemosensory olfactory receptors are virtually found on many parts of the crustacean body including antennae, mouthparts and tips of the walking appendages (Hallberg, 2011).…

A single celled organism, such as an Amoeba, has a short life because of the heavy work load and exposure to elements on all four of its sides. An Amoeba operates on one cell, so it is a lot of work and cannot get very big with just one cell. Any injury to the cell can result in immediate death to the fragile organism. Yet, it is still a life because it IS a cell, and grows, can split in half and make a new amoeba, responds to the environment, uses energy to grow and can also adapt to their environments by living in both soil and water. They use their body to surround food and “eat” it. Some amoebas have learned to cover themselves in grains of sand to protect their small bodies. Trees, cats, and single cell organisms all need oxygen, have cells, grow and reproduce, respond to stimuli, use energy, and adapt to environment so they are all living things.…
-The organism depends on its ability to sense and respond. The organisms could compete for water or hydration.…
The figure below shows a Paramecium, a single-celled freshwater protist. The hairlike structures visible on the Paramecium allow it to move. These structures are ______.…
Dinoflagellates sby 2 things, flagella and movable protein strands that propel the cell through the water. The longitudinal flagellum extends out from the sulcal groove of the hypotheca when it snaps back and forth it moves the cell forward. The flattened flagellum lies in the cingulum, the groove that expands around the equator of the cell. The motion of this provides maneuvering and forward movement. The result of this is the action of the two flagella the cell spirals as it moves.…

The key decision makers in this case are the patient, and the medical team. The big question is whether to respect the patient's autonomy and compromise standards of care or ignore the patient's wishes in an attempt to save her life. The key decision makers in this case is the woman’s husband and herself. The husband already lost an unborn child due to the mother’s religious background, should he lose his wife as well? Many religions, if not all believe in wrongs of innocent killings. If the woman is religious shouldn’t she think about the murder of her unborn child? The decision she made without accepting the blood transfusion and surgery caused her to lose her child and is the cause of her own death.…
“The Bells” is one of Poe's famous poems, in which Poe tries to make the bells sound real. He tries to make the sounds by using words instead of sound because he repeats things so often in the poem. He uses words like shrieking and twinkling. The poem “The bells” talks about how the same sound can be heard in a different tone thus giving either a sense of urgency, matrimony, a musical sound, or an alert of presence. “The bells” can be interpreted in many different ways and can be read in many different tones. The tone of voice that the speaker reads it with affects how the poems sounds, but also how the audience perceives the poem and how they’re affected by it.…
