The second choice is correct. The reticular formation is one of several
systems involved in arousal. The primary
function of this interconnected nuclei in the brainstem are modulatory and
premotor. This is also divided into
three columns which are the median, medial zone, and the lateral zone.
Oxygen is produced in the light stage of photosynthesis at Photosystem 2 and results from the splitting of water. Chlorophyll does not absorb green light so in green light there will be less water split and so less oxygen is produced.so thats how we know the reason why a leaf is the color that it is. basically it is because of chlorophyll.
Hope this helps.
Answer: B
Explanation:
G protein-coupled receptors (GPCRs), also known as seven-(pass)-transmembrane domain receptors, 7TM receptors, heptahelical receptors, serpentine receptor, and G protein–linked receptors (GPLR),comprises of a large protein family of receptors that discover molecules outside the cell and initiate internal signal transduction pathways and, eventually, cellular responses. They are called seven-transmembrane receptors because they pass through the cell membrane seven times
1) The correct answer is: 128 combinations.
The genetic combinations that are possible through independent assortment can be calculated as 2^n; where n is the number of different chromosomes.
So, using this formula for 7 chromosomes:
2^7 = 128 different combinations.
2) For a zygote produced by two barley parents, the number of possible genetic combinations can be calculated as: 2^n * 2^n
So, for 7 chromosomes: 2^7 * 2^7=16384
Both coconut and watermelon are angiospermic species. In angiosperms ovary after fertilization becomes fruit and ovules become seed. Biologically seed of coconut and seed of watermelon seed has the same property only differ in size. Both are viable seeds and after germination they produce seedling and seedling grows into adult plant.
