2.) A scientist is testing the efficiency of various pH levels by measuring average growth rate. She runs 7 trials. What is the dependent variable of this experiment?a.) Plant Growth
b.) pH of Soil
c.) Average Plant Growth
d.) Type of Soil
2.) A scientist is testing the efficiency of various pH - 1

Answers

Answer 1
Answer: I think it's B because in the question it says "she is testing the efficiency of various pH levels by measuring average growth rate". Also, keep in mind that dependent variable is what is being tested or measured in a scientific experiment. The growth of the plant would be independent variable because when testing for a independent variable it's the change or what's being controlled.

Answers

A) Coevolution

Etimologycally, coevolution means evolutionate together.

Biologically, the changes in the two species affect reciprocally.

The right option is; A) coevolution

Coevolution is the term that refers to a change in one species that results from a change in another species that it interacts with.  

Coevolution is a process of mutual evolutionary change that takes place between two or more organisms as they interact with one another.

Coevolution can happen in interactions such as between host and parasites, predators and prey and mutualism.

Which of the following best describes what Einstein’s theories tried to explain?A) the creation of the universe
B) evolution and human development
C) how the physical world functions
D) the possibility of time travel

Answers

Answer:

The correct answer is option C, how the physical world functions

Explanation:

Einstein theories were quite fascinating and revealed some concepts which have changed the way science was studied. For example the theory of relativity explained the behavior of an object in space and time (concept of four dimensional). His theory of relativity introduced the “absolute”  frame of reference according to which whenever some quantity is measured be it velocity, momentum etc. it is in reference to some thing.  

This absolute reference do not apply to the speed of light and also nothing is faster than the speed of light. Like wise his theories changed the perception of scientist/scholars  with respect to the existing scientific theories as well as the future theories to be discovered.

Describe how viruses and prions can alter cell functions

Answers

Since viruses are nonliving, they will need a host in order to take over and spread. Thus, viruses need help in order to reproduce. However on the other hand, Prions are also NON-living but they do not reproduce, they are protein that are not folded properly and continue to create those badly folded proteins to alter the cell.

The protoplasm and cytoplasm of a plant are interchangeable terms

Answers

No. These two terms aren't interchangeable. 
Protoplasm is the living content of a cell which is surrounded by a plasma membrane called the cell membrane. It is composed of a mixture of small molecules including ions, amino acids, monosaccharides and water, and macromolecules like nucleic acids, proteins, lipids and polysaccharides.
In eukaryotes,  the protoplasm surrounding the cell nucleus is known as the cytoplasm.

SOS:

The answer is FALSE!!!

The cytoplasm is protoplasm that surrounds the nucleus. All the organic substances of the cell are referred to as the protoplasm. The cytoplasm and the nucleus make up the protoplasm.

Hope this helps!!
