Explanation: because most animals eat to get the substances they need and breathing is also a big one if they don't breath they will die like the every being on this planet needs oxygen to live if we do not have those we will drop over dead.
The correct answer is C. Students communicate results in laboratory reports, and professional scientists communicate results in scientific journals.
Explanation:
Both students and scientists can carry out scientific research that involves studying a phenomenon by using the scientific method and scientific instruments. However, professional scientists and students differ in their level of knowledge and expertise in science. This makes scientific research made by scientists to have some differences in comparison to scientific research by students.
One of these differences is the way results are communicated. Indeed, students develop simple scientific research and the results are communicated in laboratory reports at school, colleges, etc. On the other hand, professional scientists develop complex research. Due to this, results are communicated in academic texts with strict criteria and that can be seen by other scientists, these are known as scientific journals.
Answer:
Kepler described the orbits of the planets as elliptical. They were thought to be circular.
Explanation:
Parfocal refers to the idea that an image should maintain focus when shifted between distinct objectives. You should only make precise focus adjustments after the image is in focus.
<h3>Why is parfocal imaging crucial in microscopy?</h3>
Parfocal goals are those that can be modified with little to no focussing. It is convenient when the lenses stay in focus when you change the magnification on your microscope. When a microscope has named objectives, this is feasible.
The picture will stay in focus while switching from a lower-power objective to a higher-power objective because high-quality microscopes are parfocal. The oil reflects more light because it has the same refractive index as glass.
