Answer:
Within the scientific community, peer review has become an essential component of the academic writing process. It helps ensure that papers published in scientific journals answer meaningful research questions and draw accurate conclusions based on professionally executed experimentation.
I don’t know what the options are, but remember viruses are:
-nonliving (they cannot reproduce without a host)
-surrounded by a protein coat
-composed of DNA or RNA
-able to live for years
-unable to thrive outside of the host cell
-classified into 4 structural classes (helical symmetry, isometric symmetry, enveloped, bacteriophage)
Answer:
1)Diffusion
2)yes, because of size difference
Explanation:
1) Biological cells live and grow by the inside and outside movement of molecules and diffusion is a process which takes place when molecules move from higher concentration area to lower concentration area. When cubes of agar alongwith indicator (phenophthalein) is added into vinegar, the hydrogen ions move from vinegar into the agar cubes and change in color appears. This change of color indicates the diffusion of vinegar into agar cubes
2) The diffusion distance differs between the cubes because of different sizes of the cubes. The difference in size results in difference of surface area which can be calculated by the volume of the cube. Larger the cube is, the more time vinegar will take to diffuse into the agar cube.
