<span>This is called an intron. An intron is a sequence that is removed during RNA splicing. It's both the DNA sequence inside a gene and the related sequence in an RNA transcript. Introns are found inside the genes of almost every organism, and also inside viruses.</span>
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.
Which disease symptoms u would like to know?
Answer:
An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals. (Draw a plant and this is tghe one you underline)
A heterotroph is an organism that eats other plants or animals for energy and nutrients. (You can draw a dog, cat, frog or a person)
I don't know if you are supposed to explain or name it, but I'll just do both.
Well, the process is called sea-floor spreading. It makes new crust at mid-ocean ridges, and the older crust, when it gets away from the ridge, gets recycled from a deep-ocean trench(Or subduction zone, I can't remember). That is why the Earth don't get bigger
