Describe the change in shape of the lens when a person looks from a near object to a distant object

Answers

Answer 1

Answer:

Accommodation is the process of changing the shape of the lens to focus on near or distant objects.

To focus on a near object – the lens becomes thicker, this allows the light rays to refract (bend) more strongly.

To focus on a distant object – the lens is pulled thin, this allows the light rays to refract slightly.

Answer:

C

Explanation:

ATP stands for adenosine triphosphate. An ATP molecule has ahead of adenose sugar and a tail of three phosphate groups. Energy is stored in the bonds between phosphate groups, so when your body needs energy, it breaks off some phosphate and releases energy to the immediate environment.

There is a U-tube in which solutions in two arms A and B are separated by a membrane. Arm A contains glucose with concentration of 0.4 mol per liter and sodium chloride with concentration of 0.5 mol per liter. Arm B contains glucose with concentration of 0.8 mol per liter and sodium chloride with concentration of 0.4 mol per liter.
The solutions in the arms of a U-tube (the figure) are separated at the bottom of the tube by a selectively permeable membrane. The membrane is permeable to sodium chloride but not to glucose. Side A is filled with a solution of 0.4 M glucose and 0.5 M sodium chloride (NaCl), and side B is filled with a solution containing 0.8 M glucose and 0.4 M sodium chloride. Initially, the volume in both arms is the same.

If you examine side A in the figure after three days, the concentrations of glucose and NaCl should be _____________.

find evidence that opposes a scientific position.



find evidence that supports a scientific position.



find evidence that proves a scientific position.


find evidence that disproves a scientific position.

Answers

It’s to find evidence that supports a scientific position! It’s actually in the definition, if you search up corroborate! Really hope this helps ya, and have a great rest of your day.

The most correct option as to what corroborating information means would be to find evidence that supports a scientific position.

Corroborate is an English word that means 'to agree with' or 'give credence to'.

Hence:

Finding evidence that opposes a scientific position is a wrong option because that is the complete opposite of what corroborate means. Finding evidence that approves a scientific position is also a wrong option because corroborating a statement does not necessarily make the statement to be scientifically correct.Finding evidence that disproves a scientific position is also incorrect. Corroborate neither translates to approve nor disprove,

Therefore, the correct option that clearly explains what corroborate means in the context of science is to find evidence that supports a scientific position.

The prevalence of CRE infections in health care settings has increased significantly in recent years, in part because these organisms are able to share plasmid-encoded resistance genes. Which method of horizontal gene transfer is most likely responsible for transfer of the plasmid between bacteria

Answers

Answer:

Bacterial conjugation

Explanation:

Carbapenem-resistant Enterobacterales (CRE) are different types of bacteria that lead to infections in healthcare settings. Moreover, a plasmid is a small piece of DNA that can replicate independently from the bacterial chromosome. Bacterial conjugation is a type of horizontal gene transfer by which plasmids are transferred from one bacterium referred to as 'donor' into another called 'recipient' by sex pili. Plasmid transfer is unidirectional and depends on physical contact between bacterial cells. In this case, it is expected that this type of DNA transport mechanism occurs among patients occupying the same rooms in healthcare settings.

Forming a hypothesis is the first step of the scientific method.

Answers

Answer:

The first step in the Scientific Method is to make objective observations. These observations are based on specific events that have already happened and can be verified by others as true or false. Step 2. Form a hypothesis.

Explanation:

The hypothesis is an educated guess as to what will happen during your experiment. The hypothesis is often written using the words "IF" and "THEN." For example, "If I do not study, then I will fail the test." The "if' and "then" statements reflect your independent and dependent variables

Prior to the industrial revolution in the mid-1800s, a species of moth had light-colored wings speckled with small black spots. This coloration camouflaged the moths resting on the birch trees growing in their native habitat, since birch bark has similar coloring. In the early 1900s, this changed as dark soot produced by industrial pollution coated birch trees such that the trees lost their speckled coloring. Years later, it was observed that the moths of this species had changed from being light and speckled to being solid black. Which is the most plausible reason for this change

Answers

Answer:

The dark colored moths were due to a genetic mutation, and were more than likely present before the Industrial Revolution. Their fitness was low because predators could easily see them on the light-colored trees. They would be eaten before they could reproduce and pass on their genetic mutation. After the trees became darkened by soot, the darker colored moths now had the survival advantage, able to "hide" from predators. The lighter colored moths became more visible to predators, and the advantage shifted. Now, the light colored moths were more visible to predators, were eaten, and didn't have the chance to reproduce. The darker moths with the mutation had the survival advantage, blending in with the soot-covered trees, and were able to reproduce at higher rates, passing the mutation on to later generations.

The fruit of the mistletoe, a parasitic angiosperm, is a one-seeded berry. In members of the genus Viscum, the outside of the seed is viscous (sticky), which permits the seed to adhere to surfaces such as the branches of host plants or the beaks of birds. What should be expected of the fruit if the viscosity of Viscum seeds is primarily an adaptation for dispersal rather than an adaptation for infecting host plant tissues

Answers

Answer:

We should expect that the fruits should grow in population and spread more easily.

Explanation:

Like the relationship between bamboo and pandas, the relationship between the seeds and the beaks of birds should allow the seeds to spread to other areas more easily that would otherwise be a very gradual process if the seeds did not evolve its viscous ability.

7. To test a new voice feature in a cockpit design a flight simulator was used. The simulator was programmed to
give visual readings of flight information, or to give visual and auditory (voice) readings of flight information. All
test pilots were put through a simulated emergency landing procedure, but were randomly assigned to the
visual, or visual and auditory conditions. Flight experts rated each pilot's performance in the simulator on a
scale of 1 (very poor) to 10 (excellent).

Answers

The variables in the simulation procedure carried out are :

Independent variable = Simulator Independent variable = Simulator Dependent variable = Performance

The dependent and independent variables are critical in any experimental study as both variables encompasses the variable to be measured and the variables manipulated in other to obtain the variable to be measured.

Independent variable : This is also called the predictor variable which is tweaked in other to obtain changes in the measured or dependent variable. In the experiment performed, the simulator is the independent variable has it has different visual or visual and auditory conditions capable of causing changes to the performance rating.

The dependent variable is the variable being measured in an experiment. In this case, it is PERFORMANCE. It is the measured output obtained as the the pilot are being rated based on the simulation.
