Pairs

Answers

First image shows a stationary organism whereas the second image indicates predator.

The first picture represents a leaf structure which is a part of plant and we know that plant is a stationary organism means it can't move from one place to another so that's why it is called a stationary organism.

While on the other hand, the second picture represents predator due to the presence of sharp teeth which helps the predators in catching and tearing of prey so we can conclude that first image shows a stationary organism whereas the second image indicates predator.

An inventor claims to have invented an artificial kidney for patients that need a kidney
transplant. Which of the following would be a reason that the scientific community might
reject this claim?

A. Previous investigations were unable to obtain the same results.
B. The inventor failed to present observations with data.
C. Investigations were performed in an unknown laboratory.
D. The device failed to follow law of conservation of mass

Answers

I believe the answer is B

All of the given options could potentially be reasons why the scientific community might reject the inventor's claim, but the option that specifically relates to the principles of science is option D: the device failed to follow the law of conservation of mass.

What is an artificial kidney?

In the case of an artificial kidney, the device is supposed to filter out waste products from the blood, which is then supposed to be removed from the system in a measurable form, such as through urine or dialysis fluid. If the device fails to remove the waste products from the blood, or if it makes them disappear without a measurable output, it would suggest that the device is not functioning as claimed and may not be effective in treating patients who need a kidney transplant. Therefore, the scientific community would likely reject the inventor's claim until there is evidence that the device follows the fundamental principles of science, such as the law of conservation of mass

Hence, the option that specifically relates to the principles of science is option D: the device failed to follow the law of conservation of mass.

Considering that cells vary in shape,what other dimensions or parameters of the cell could be used to estimate cell size?​

Answers

Answer:

Three general factors determine cell shape: the state of the cytoskeleton, the amount of water that is pumped into a cell, and the state of the cell wall. Each of these three factors is highly dynamic, meaning they are constantly in flux or can be suddenly changed. This dynamism is how cells can vary in shape.
