If there is electrochemical cell where Q = 0.0010 and K = 0.10 then the truth about Ecell and E°cell is,
Ecell is positive and E°cell is negative.
E° = (RT/nF) InQ = (RT/nF) × In(K/Q) = Positive.
Since ( K/Q) = 100 then In(K/Q) = positive
Answer:
a. they can fix carbon at the lower CO2 concentrations that develop when the stomata are closed
Explanation:
C4 plants are those that have the capacity to fix CO2 even when a tiny concentration of it is available.
Desert condition is characterized by dryness and strong heat with both condition capable of creating water stress in plant as a result of evapotranspiration. In order to reduce evapotranspiration rate, desert plants (most C4 plants) close their stomata during the day.
<em>Stomata closure limit the diffusion of CO2 into desert plants and the small concentration of CO2 that results is utilized by a special enzyme in the plants.</em>
The correct option is a.
Answer:
Chromosomes are like a ball of yarn in the sense that there are multiple components that make up the structure. Genes can be in similitude of the smallest threads in the yarn and when a multitude of genes are put together they make a DNA strand or a long, thick thread of yarn. Lastly, when DNA is twisted together, it becomes bundled together, making a chromosome or a "ball of yarn".
Explanation:
The second one I believe.
Answer:
a dam flooding a valley
Explanation:
It would be a dam flooding a valley because in a new ecosystem there would then be a increased load of phosphorus and nitrogen and increased algae growth.
