D. Plants have adapted to deal with the sun in many different ways, and this is one. The stomata are regulated by guard cells, which are activated by different things depending on the species of plant, and guard cells are supposed to keep the stomata from staying open all the time and losing too much water to evaporation. So, the solution is to have the stomata on the bottom of the leaf to prevent direct sunlight contact (and therefore more evaporation), and guard cells to protect the stomata.
Answer:
see the answer below
Explanation:
<em>The cells of the brain and spinal cord are irreplaceable because these cells do not undergo cell divisions like some other cells of the body.</em>
<u>Through cell division of the vegetative cells, damaged cells of the body are replaced by new cells. The cells of the brain and spinal cords however are special cells that will not divide under ordinary conditions. Hence, when there is any form of damage, there are no new cells to replace the damaged cells.</u>
Answer:
This is great because in a changing eviroment (needing to change if they want to survive) they may reproduce sexually for genetic diversity, whereas if they are already well adapted to the area it is possilbe for them to pass on ALL of the traist that allowed them to survive in the first place.
Hope this helps :)
The given blanks can be filled with NADPH and ATP.
The dark reactions or light-independent reactions of photosynthesis refers to the chemical reactions, which transforms carbon dioxide and other constituents into glucose. These reactions take place in the stroma, that is, the fluid occupied region of a chloroplast external to the thylakoid membranes. These reactions use the products of light-dependent reactions, that is, NADPH and ATP to do further processes.
Technique b is more advantageous because if they used technique a. The bees that pollinate the crops would die and the crop would not make more seeds. Hope this helps(:
