Counterclockwise rotation of the flagellum causes a bacterial cell to swim or ______ towards a stimulus, interrupted by clockwise rotation in which the cell ______ and changes its course.
Counterclockwise rotation of the flagellum causes a bacterial cell to swim or run towards a stimulus, interrupted by clockwise rotation in which the cell tumbles and changes its course.
How does a bacterium respond to stimuli?A bacterium is a unicellular organism that posseses a structure called flagellum.
Flagellum in bacteria is a long, whiplike proteinaceous appendage, used for locomotion.
However, a counterclockwise rotation of the flagellum causes a bacterial cell to swim or run towards stimulus. This rotation is interrupted by a clockwise rotation of the flagellum that causes the bacterium to tumble.

What additional procedure must be done to indicate glucose is present?
The glucose urine test estimates the amount of sugar (glucose) in a urine sample. The existence of glucose in the urine is called glycosuria or glucosuria. Glucose classes can also be calculated using a blood test or a cerebrospinal fluid test.
What is diffusion?Diffusion refers to the natural tendency of a system to homogenize the concentrations of chemical species within it.
It is an irreversible transport phenomenon that results in the migration of chemical species into a medium. Under the effect of the thermal agitation, a displacement of the constituents of the zones of high concentration towards those of low concentration is observed.
Thus, The glucose urine test estimates the amount of sugar (glucose) in a urine sample.

Answer:
divergent,mid ocean ridges
Explanation:
the seafloor diverge from each other causing the land to go thinner and thinner and thinner and make an opening between the floors and continue to move away from each other until they touch a more firm land to be able to stop, then the mid ocean ridges come between the floors where inside there is water and on the side there are the ridges

A fossil of a new primate species is discovered. scientists find evidence that members of this species traveled long distances without putting their hands down on the ground and used tools. which trait would the fossil most likely have? a foramen magnum at the back of the skull a curve in the lumbar region of the spine a femur angled outward an opposable big toe
The trait would the fossil most likely have is a curve in the lumber region of the spine.
What is the concept of fossil?Fossils are remains or traces of animals and plants preserved in rocks. Remains are parts of an animal (eg bones, teeth, scales) or plant (eg trunks) and traces are evidence of its existence or activities (eg footprints).
From the fossils it is possible to see the evolutions that the animals suffered in this case it was a curve in the lumber region of the spine.

1. How do you think your organs work together to digest food?
2. What other inventions do you think are based on the functions of the digestive system?
3. How might you be able to tell that enzymes are working in your body?
4. How do different types of food change the number of digestive enzymes present in your body?
Answer:
1. Food moves through your GI tract by a process called peristalsis. The large, hollow organs of your GI tract contain a layer of muscle that enables their walls to move. The movement pushes food and liquid through your GI tract and mixes the contents within each organ.
2.The SmartPill is an ingested, wireless device for measuring the health of the digestive system. As it passes through the digestive tract, the capsule transmits data to a receiver, which is later returned to the doctor and the information downloaded onto a laptop computer.
3. When its not working many of the uncomfortable reactions such as an upset stomach, allergy-like symptoms or irritability are actually signs that the enzymes are working. The body is cleaning itself out and the healing process is starting.
4.One of the main reasons for reduced output of digestive enzymes is poor exocrine pancreatic function. The causes of Exocrine Pancreatic Insufficiency (EPI) are very diverse ranging from: Problems with the endocrine part of the pancreas such as insulin dysregulation from diet high in refined carbohydrates and diabetes.

5. Which statement best describes the geocentric model of our solar system?
Answer:
Earth is at the center.
Explanation:
The geocentric model is a model system that explains how the planets in the solar system move around.
Ptolemy established the geocentric concept, which states that the earth is at the center of the solar system and that other celestial bodies, including planets and stars, rotate around it.
Nicolas Copernicus invalidated this model system by explaining that the sun is at the center of the solar system and that the planets rotate around it.

You’ve found some fossil bones while digging in your backyard. could they be dinosaur bones? using carbon dating, you determine that 3% of the original radioactive carbon-14 is still radioactive. (the rest has decayed into nitrogen-14.) how many half-life cycles has it gone through? approximately half-life cycles.
Since 3% of the original radioactive carbon-14 is still radioactive, the carbon-14 radioisotope has undergone five half-lives.
What is Half-Life?Half-life of a substance is the time it takes for half the original amount of the substance to decay.
Radioactive elements decay spontaneously according to their half-lives.
Since 3% of the original radioactive carbon-14 is still radioactive, the number of half-lives undergone is determined as follows:
After one Half-Life, 50% remains
After two half-lives, 25% remains
After three half-lives, 12.5% remains
After four half-lives, 6. 25% remains
After five half-lives, 3.125 % remains.
Therefore, the carbon-14 radioisotope has undergone five half-lives.
