During which phase of mitosis do the chromosomes become distinctly visible in the microscope?
Prophase of mitosis do the chromosomes become distinctly visible in the microscope.
During metaphase, the nucleus dissolves and the cell's chromosomes condense and move together, aligning in the center of the dividing cell. At this stage, the chromosomes are distinguishable when viewed through a microscope. The first stage of mitosis and of meiosis I and II.
During prophase the chromosomes become visible as distinct structures, the nuclear envelope breaks down, and a spindle forms (Meiotic prophase I is more complex, and includes synapsis of homologous chromosomes and crossing over). During Prophase chromosomes become Clearly visible, nuclear envelope disappears, kinetochores and spindle fibers form.

During a tapeworm infection, you would expect to see increased numbers of eosinophils. Neutrophils are most effective at: fighting a bacterial infection.
Leukocytes protect the body against invading microorganisms and body cells with mutated DNA, and they clean up debris. Platelets are essential for the repair of blood vessels when damage has occurred; they also provide growth factors for healing and repair.
The granules of eosinophils include antihistamine molecules, which counteract the activities of histamines, inflammatory chemicals produced by basophils and mast cells. Some eosinophil granules contain molecules toxic to parasitic worms, which can enter the body through the integument, or when an individual consumes raw or undercooked fish or meat which causes infection.

Polysaccharide digestion and glycogen breakdown involve sequential cleavage from ________ ends of glucose polymers.
Sequential cleavage from the non-reducing terminals of glucose molecules is required for both glycogen degradation and polysaccharides hydrolysis.
Why non-reducing end is selected for digestion?
A polysaccharide's non-reducing end is the one where an anomeric carbon participates in the glycosidic connection. The elimination of carbohydrate remnants one at a time out from the non-reducing terminal occurs during glycogenolysis and polysaccharides hydrolysis.
For example, several enzymes are involved in glycogenolysis in the liver and muscle. An example of such an enzyme is glycogen phosphorylase, which catalyzes the successive dissociation of the alpha 1->4 glycosidic bond that connects two glucose molecules at a non-reducing terminal of glycogen. The last glucose residue is eliminated as alpha-D-glucose 1-phosphate.That is why non-reducing end of glucose is chosen for digestion or breakdown of the carbohydrate polymer.

The most commonly used microscope, which uses visible light to view cells, is called a Light microscope.
Basically, a Light microscope contains two subsystems: an illumination system for illuminating the sample as well as an imaging system which produces a magnified image of the sample after its interaction with light. The image thus formed can be viewed by the eye or through a camera.
Light from a source is focused onto the sample or object using a mirror and condenser lens. The light after passing through the sample is collected by an objective lens, forming an intermediate image which is finally imaged by the eyepiece lens and transmitted to the eye in the form of a magnified image of the sample.

Moving your finger across a textured surface can produce vibrations that are interpreted as texture. These vibrations are defined as?
Moving your finger across a textured surface can produce vibrations that are interpreted as texture. These vibrations are defined as temporal cues.
Temporal envelope (ENV) or temporal cues are changes in the amplitude and frequency of sound perceived by humans over time. These temporal changes are responsible for several aspects of auditory perception, including loudness, pitch and timbre perception and spatial hearing.
Complex sounds such as speech or music are decomposed by the peripheral auditory system of humans into narrow frequency bands. The resulting narrow-band signals convey information at different time scales ranging from less than one millisecond to hundreds of milliseconds. A dichotomy between slow "temporal envelope" cues and faster "temporal fine structure" cues has been proposed to study several aspects of auditory perception (e.g., loudness, pitch and timbre perception, auditory scene analysis, sound localization) at two distinct time scales in each frequency band.
Over the last decades, a wealth of psychophysical, electrophysiological and computational studies based on this envelope/fine-structure dichotomy have examined the role of these temporal cues in sound identification and communication, how these temporal cues are processed by the peripheral and central auditory system, and the effects of aging and cochlear damage on temporal auditory processing.
Although the envelope/fine-structure dichotomy has been debated and questions remain as to how temporal fine structure cues are actually encoded in the auditory system, these studies have led to a range of applications in various fields including speech and audio processing, clinical audiology and rehabilitation of sensorineural hearing loss via hearing aids or cochlear implants.

what is a polar molecule? Why is water considered polar?
Answer:
A polar molecule is usually formed when the one end of the molecule is said to possess more positive charges and whereas the opposite end of the molecule has negative charges, creating an electrical pole.
Water is polar because of the bent shape of the molecule. The unequal sharing of electrons between the atoms and the unsymmetrical shape of the molecule means that a water molecule has two poles - a positive charge on the hydrogen pole (side) and a negative charge on the oxygen pole (side).

Our blood vessels are lined with muscles that allow for automatic dilation and constriction based on environmental situations. what kind of muscle tissue lines the blood vessels?
Smooth muscle, a type of tissue that allows for constriction or dilation, makes up the blood vessel walls. The absence of striations (stripes), which are present in both skeletal and cardiac muscles, gives smooth muscle its name.
Only smooth muscle cells are found in blood arteries. The tunica media houses these muscle cells, elastic fibres, and connective tissue. Even though vessels only have smooth muscles, skeletal muscle contractions are crucial for the venous system's ability to transport blood from the periphery to the heart.
The autonomic nervous system regulates the smooth muscle found in the walls of hollow internal organs like blood vessels, the gastrointestinal tract, the bladder, and the uterus. Since smooth muscle cannot be consciously controlled, it behaves spontaneously.
