Dalton’s theory was identified using

light microscope images of atoms.
the experimental results of other scientists.
water vapor and air experiments.

Answers

Answer 1

Answer:

Explanation:

Actually it was the experimental results of other scientists. The main stems of the theory was the indivisibility of small spheres (his image) that represented the elements he knew which reacted with other elements.

They seemed to give the same ratios in reactions (definite proportions) and multiple whole number ratios. Look up Lavoisier.

n a classic example of this type of trait: the arms of a human, the legs of a cat, the flippers of a whale, and the wings of a bat, all have similar structures as seen in the picture above. Each of the structures serves a unique purpose for the different organisms and their lifestyles. However the similarity between the structures implies that they were derived from a common ancestor. What kind of trait is being described in this example

Answers

Answer:

Scientists must collect accurate information that allows them to make evolutionary connections among organisms. Similar to detective work, scientists must use evidence to uncover the facts. In the case of phylogeny, evolutionary investigations focus on two types of evidence: morphologic (form and function) and genetic. In general, organisms that share similar physical features and genomes tend to be more closely related than those that do not. Such features that overlap both morphologically (in form) and genetically are referred to as homologous structures; they stem from developmental similarities that are based on evolution. For example, the bones in the wings of bats and birds have homologous structures (Figure 1).

Figure 1. Bat and bird wings are homologous structures, indicating that bats and birds share a common evolutionary past. (credit a: modification of work by Steve Hillebrand, USFWS; credit b: modification of work by U.S. DOI BLM)

Notice it is not simply a single bone, but rather a grouping of several bones arranged in a similar way. The more complex the feature, the more likely any kind of overlap is due to a common evolutionary past. Imagine two people from different countries both inventing a car with all the same parts and in exactly the same arrangement without any previous or shared knowledge. That outcome would be highly improbable. However, if two people both invented a hammer, we can reasonably conclude that both could have the original idea without the help of the other. The same relationship between complexity and shared evolutionary history is true for homologous structures in organisms.

Why is Dr. Elizabeth Cochran’s sensor important to earthquake research? How can it help develop an earthquake warning system?

Answers

Answer:

According to Cochran, these sensors become temporary seismic stations, enabling scientists to automatically monitor and retrieve data from six months to a year after an earthquake. Therefore, scientist can detect earthquake through information collected from the last earthquake.

Explanation:

Answer:

Dr. Cochran has invented a device to use on any laptop to detect an earthquake. This device can warn people about earthquakes immediately. These detectors are inexpensive and work on any computer. Scientists can create more of these sensors and distribute them to all residents in earthquake-prone areas. The sensors would let people know about earthquakes so they could go somewhere safe without wasting time.

A skateboarder drops in off the top of one side of the half pipe shown below. She does not push off and starts from rest. She stands straight as she skates down one side and up the other. She expected to get to the top of other side but didn’t make it. The skateboarder recalled the law of conservation of energy from science and didn’t understand why she didn’t make it to the top of the other side.

Which of the following actions would help the skater reach the top of the other side of the half pipe?


Lubricate the wheels in order to reduce frictional force that is causing the skateboard to lose velocity and bend down while skating off the side and bottom of the half pipe.


Hold a weight in order to increase her mass and cause the skateboard to move with a greater velocity down the half pipe.


Sit on the skateboard in order to lower her center of mass and increase the potential energy of the skateboard.


Push off at the bottom of the half pipe in order to replace lost energy and add kinetic energy to the skateboard.

Answers

The actions that will help the skater reach the top of the other side of the half pipe is to lubricate the wheels in order to reduce frictional force that is causing the skateboard to lose velocity and bend down while skating off the side and bottom of the half pipe.

The law of conservation of energy from science states that energy can neither be created nor destroyed but can be transformed from one form to another.

The skateboarder couldn't make it to the top of one side of the half pipe because the kinetic energy that was generated was converted to heat energy through friction.

As the heat energy is lost to the surrounding environment, the skateboard loses velocity.

Bending down by the skateboarder will provide additional energy to make up for the lost energy.

Therefore, in order for the skateboarder to reach the top of the other side of the half pipe, she has to lubricate the wheels in order to reduce frictional force that is causing her to lose velocity and bend down while skating off the side and bottom of the half pipe.
