Your science class has taken swabs throughout the school. The image shows the
petri dish containing a bacterial culture that developed from a swab of one computer keyboard in the classroom. You would like to make a detailed observation of the internal structures of the bacteria in your culture. You know
that In order to see just their shape, it is necessary to use a magnification of
about 400x to 1000x. Based on this, develop a logical argument for using a transmission electron microscope.
A. The TEM magnifies 1,500,000X and produces a 3D image.
B. The TEM produces a 2D image of whatever specimen you are viewing.
C. The TEM magnifies up to 200,000X and you can see great detail, including the internal structure of cells.

Mollusk fossils were excavated and collected from a coastal cliff. Scientists studying the fossils observed patterns of changing shell shape in the mollusks. The scientists identified a period of stability or stasis, followed by rapid change, and then stasis again with regard to shell shape. Which of the following statements best predicts the result of a comparison between the fossils found before and after the period of rapid change?
a) The same species will be found in both static periods, but they will have different shell shapes.
b) The same species will be found in both static periods, but the species in the second static period will have smaller shells due to the stress of undergoing capid change
c) Most of the species found in the first static period will be absent in the second static period.
d) Most of the species found in the second static period will resemble each other more than the species found in the first static perlod
Answers
The statement that best predicts the outcome of a comparison between fossils found before and after the period of rapid change is that the same species will be found in both static periods but will have different shell shapes.
How does the evolution of species work?For Lamarck the evolution of the species occurs due to the modifications that are imposed by the environment in which they live. New characteristics are acquired by the repeated use or disuse of an organ or body part. Defines that, according to the use of a particular member, it would be developed.
With this information, we can conclude that the statement that best predicts the outcome of a comparison between fossils found before and after the period of rapid change is that the same species will be found in both static periods, but will have different shell shapes.

Summary of Photorealism
The name Photorealism (also known as Hyperrealism or Superrealism) was coined in reference to those artists whose work depended heavily on photographs, which they often projected onto canvas allowing images to be replicated with precision and accuracy. The exactness was often aided further by the use of an airbrush, which was originally designed to retouch photographs. The movement came about within the same period and context as Conceptual art, Pop art, and Minimalism and expressed a strong interest in realism in art, over that of idealism and abstraction. Among several male practitioners of Photorealism there is an interest in themes of machinery and objects of industry such as trucks, motorcycles, cars, and even gumball machines, whereas Audrey Flack, the sole female practitioner, infuses her works with greater emotionality and the transience of life. Ultimately, the Photorealists were successful in attracting a wide audience, but they are often overlooked by art historians as an important avant-garde style.

Greg is in a bike race. At mile marker four (out of ten), his speed was measured at 13.5 mph. Which best describes the measured number? It is the average speed of the bike rider. It is the instantaneous speed of the bike rider. It is the instantaneous velocity of the bike rider. It is the average velocity of the bike rider.Which is a valid velocity reading for an object? 45 m/s 45 m/s north 0 m/s south 0 m/s
Answers
Answer:
The correct answer is - It is the instantaneous speed of the bike rider.
Explanation:
Velocity is the speed with the direction so, it is a vector while speed is the specific distance covered in a unit of time, as there is no sense of direction it is scalar.
The instantaneous speed is the speed of an object at a particular or specific instant of time, in this case, the speed of the biker is mentioned not the velocity as a direction not given
Thus, the correct answer is option - It is the instantaneous speed of the bike rider.
