The answer would be 25%
Carbon 14 is radioactive material with 5700 year of half-time which will change it into carbon-12, a more stable substance. If the age of the fossil is 11,400 years old, then the amount of half-time passed would be: 11,400 years/ (5,700years/ half-time)= 2 half-time.
Since it undergo 2 half-time, the percentage should be: 100% * (1/2)^2= 25%
Answer: The shoot grows up towards the sunlight is Positive Phototropism
The root grows down the soil is Positively Geotropism / positive gravitropism.
happy to help again :)
<span>"Carrier proteins bind to the substances they transport across the membrane via facilitated diffusion, whereas channel proteins provide a pore for substances to move across the membrane via facilitated diffusion."
This is the most correct option.
The main difference, when comparing these two gates of transportation across a membrane through the same process (via facilitated diffusion or any other), is that carrier proteins bind to the substances they transport and only communicate with one environment of the cell (whether intracellular or extracellular) at the time, while channel proteins let substances move across the membrane without any binding being opened to both cell environments.</span>
Answer:
La diversidad de un ecosistema depende de dos factores, el número de especies presente y el equilibrio demográfico entre ellas. ... Por otra parte, entre dos ecosistemas que tienen el mismo número de especies, consideraremos más diverso al que presenta menos diferencias en el número de individuos de unas y otras especies.
